Function
Handbuch-KnxSmartmeter-85A-en-3.odt, 2018-10-04 Seite 4 von 69
The KNX Smartmeter is a bidirectional counter for measuring the active and reactive power or
energy, as well for power quality monitoring. The measurement will be done in three-phase
system or in three separate single-phase systems with the accuracy of class 1 (1%)
In the accuracy class 1 according to EN 62053-31 only accuracy requirements for the
measurement range between 2% and 100% of rated current are determined. For smaller
currents no requirements are defined, as these can not be accurately detected with conventional
current transformers. In contrast, the Enertex KNX Smartmeter uses high precision (Rogowski-)
current sensors which are calibrated to the device in factory. Thus, very small currents to
0.002% (2mA) of rated current are accurately measurable. In addition, the current is measured
with very little loss (< 2mW loss). The provided current sensors are suitable for through-hole
mounting and can be installed directly at the main supply point of the grid.
The Smartmeter is powered exclusively via the bus. Therefore, the device can even be operated
if there is no voltage at the voltage inputs or the voltage has been separated.
The measurement range of the active power extends from 0.5W to 19.550W or 58.650W (threephase). Energy values or measurement values for monitoring the power quality can be recorded
for analysis on a SD card.
All measured values (current, voltage, active power, reactive power, active energy, reactive
energy, power factor, THD-U, THD-I, power harmonics, unbalanced load, zero current, power
frequency) are shown on the KNX bus.
Besides specialized functions for performance-based load control, optimization of the inherent
energy demand with PV facilities, calculating the usage or feeding charge with tariff switching
the ETS application also provides various monitoring functions. In case of exceed of limits these
functions report events as power outages, high voltage spikes, high power distortion, high
reactive energy, highly non-uniform loading of the three phases (unbalanced load) or high
neutral loading on the bus. To assess the power quality harmonics up to the 50th harmonic of
current and voltage are measured. The numerous monitoring features enable fast accurate
analysis of network-related failures, malfunctions and damages of electrical equipment.
The device variant with the RT option can also be operated without a KNX bus. To do this, a
24VDC power supply must be connected to the KNX terminal. In this mode, all measurement
data of the recording mode "All measured values without mains harmonics" are recorded on the
SD card every minute as described in the section "Recording on the SD card". The recording
times for the measured values are selected in this mode according to an internal batterybuffered clock, which is factory set to the local time of Berlin (UTC / GMT +1 hour) and deviates
from the real time by a maximum of one minute per year. If necessary, the clock can be adjusted
using the SD card. The adjustment of the clock without KNX bus is described in section
"Adjusting the real-time clock without bus access".
Note: The security against tampering of the current counter, required for billing purposes, can
not be guaranteed with this Smartmeter. Therefore this KNX device is not a current counter for
billing purposes in terms of the standard (for example IEC 62052-11).

ATTENTION DANGER!
Electrical shock on contact with live parts. Electrical shock can result in death.
Disconnect the mains before working on device and cover up live parts in the
vicinity!
The neutral conductor and the measurement inputs for the 3 voltage measurement channels V1,
V2 and V3 are connected to the overlying screw terminal. When measuring a three-phase
system the phases L1, L2 and L3 have to be connected to V1, V2 and V3. If the Smartmeter is
not in three-phase operation then the phase voltage of the corresponding current channel has to
be connected to voltage measurement channel V1, V2 and V3. For example, if three powers are
to measure at one single phase, then this phase has to be connected to all three channels V1,
V2 and V3. The supply for the voltage inputs may be made from any location downstream the
main fuse, since the voltage inputs are designed for over voltage category IV. Insulation and
electro-magnetic imunity is designed for overvoltage category 4. So, the voltage inputs need not
to be additionally fused.
The EIB/KNX bus is connected on the upper left, grey / red terminal. The Smartmeter is powered
solely by the KNX bus.
Optionally a ground can be connected to one of the three ground terminals. By a connected
grounding the measurement accuracy for very small currents and powers is increased. Thus,
when measuring the current, the measurement deviation is reduced by about 0.3mA or when
measuring the power the deviation is reduced by about 70mW. By connecting the grounding the
KNX bus is connected via a capacitance of 15nF to ground.

Assembly of the current sensors
The current-carrying conductor, to be measured, must be passed through the current sensor. If
possible, the line should be passed vertically through the current sensor. Thus, the highest
precision is achieved in the current measurement. In order to fix the current sensor, it could be
fixed with a cable strap at the conductor. It is recommended for safety reasons to lead the
conductor with insulation through the current sensor.
Handbuch-KnxSmartmeter-85A-en-3.odt, 2018-10-04 Seite 8 von 69
Figure 2: Dimensions of the 85A current sensor in mm
Safety note: In the vicinity of label 1 of Figure 2 the current sensors cable is only single
insulated. At this point a savety distance of at least 5mm has to be adhered to all non insulated
live conductors. Similarly a safety distance of at least 10mm from the screw terminals has to be
adhered to all non insulated live conductors. However, the sheath of the line for the current
sensors has a reinforced insulation. Hereby no safety distances to the vicinity are required.
Since the current sensors are calibrated for each current channel it must be ensured that the
accompanying current sensors are connected to the corresponding channel. For this purpose a
corresponding marking of the channel is mounted on each current sensor. In addition, the
current sensors should be connected only to that Smartmeter, with which they were delivered.
To avoid any confusion, the serial number of the Smartmeter is attached to the line of a current
sensor. The serial number can also be recovered lateral of each Smartmeter.
A power count arrow (for positive power count direction) is attached by
on the current
sensors. A power flow in this direction corresponds to a positive power value. Usually, the
current sensors are mounted so that the power count arrow shows from the energy source to
the energy consumers, so that an energy consumption has a positive impact for the balance
energy counter.
The lines to the current sensors should be laid according to EMC requirements. This is
especially important when a high accuracy for currents below 100mA (equivalent to 25W) is
required. Therefore the following recommendations are made:
• The line should be laid in a minimum distance of 2cm to power lines.
Enertex® Bayern GmbH – Ebermannstädter Straße 8 - 91301 Forchheim - Deutschland - mail@enertex.de
Page 9
Handbuch-KnxSmartmeter-85A-en-3.odt, 2018-10-04 Seite 9 von 69
• The line should be laid at a distance of at least 10cm to high-frequency sources of
interference. These include for example:
◦ Inverter, converter
◦ WLAN Router
◦ Counter with GSM interface
◦ Equipment of a radio - bus, as Enocean, KNX-RF ...
For the highest precision the lines to the current sensors can also be cut to the minimum
required length. When shortening it is to make sure that also the drain wire is connected to the
shield terminal. In addition, care must be taken that after shortening, the cable shield is again
insulated by a shrinking tube, as it was the case in the original condition. As an alternative to this
insulation the electrical safety can also be ensured by maintaining a safety distance between the
non - insulated part of the shield and all the live conductors by at least 10mm.
If necessary, it is also possible to extend the lines for the current sensors up to 10m. However,
an increasing cable length is accompanied by a higher disturbance in the measurement signal.
Thus, the measurement accuracy for small currents is reduced. It is therefore recommended not
to extend the line, if currents below 500mA (about 100W) shall be accurately measured. To
affect the measurement accuracy as little as possible in a case of an extension the following is
recommended:
◦ Only use shielded lines with at least 0.5mm² . The shield of the extension must be
connected to the shield wire (drain wire) of the existing measurement line.
For safety reasons the extension has to be attached so that from the shield and the wires of the
extension to all live parts in the vicinity of the extension a double or reinforced insulation is
maintained. This can be achieved by insulation and/or the observance of minimum distances.
Commissioning
After connecting all the cables according to the connection diagram 1 the device is ready for
operation. Once the KNX bus is connected, the “POWER” LED lights up permanently green after
a short start-up (about 3 seconds). From that time the device performs measurements
continuously.
By a short light up the channel LEDs E1, E2 and E3 signalize measuring an energy amount of
1/1000 kWh in the particular channel. When the Smartmeter record data onto the SD card, the
POWER LED lights up red during the writing process. To prevent data loss on the SD card the
SD card may not be drawn during this writing phase. SD card is inserted in a way, that the
contacts of the SD card are on the top.
◦ The extension should be soldered to the existing measurement line.
◦ The shield of the extension or the extension drain wire must be connected to the
Smartmeter at the shield terminal.

Examples of settings
Below examples are presented, which show how the KNX Smartmeter can be used. To this end
appropriate adjustments in the ETS will be shown. The adjustments can be adopted directly.
Example 1:
Visualization of
energy consumption
Handbuch-KnxSmartmeter-85A-en-3.odt, 2018-10-04 Seite 10 von 69
In the first example the progress of energy consumption and the progress of the energy costs of
a residential house shall be recorded and shown on the bus. The consumption values
transmitted on the bus can be visualized for example on the web server of Enertex EibPC over
the last 30 hours.
Figure 3: Example of the visualization of energy consumption
Furthermore it is shown in this example, how the progress of the three-phase active power can
be displayed completely on the bus and the Smartmeter is configured such, that it also records
all measurement values on the SD card every 15 minutes.
In this example the following topics are treated: Installation of the Smartmeter, tariff counter,
intermediate counter, preempting a count, SD card, transmitting in case of change and time.
In this example the installation of the Smartmeter is a three-phase at the house connection.
Generally the current sensors are installed directly downstream the current counter of the
energy supplier. Similarly the voltage may be tapped directly downstream the current counter.

Figure 4: Connection of Smartmeter to record the total energy consumption of a residential
building
When connecting make sure that the current sensors are oriented such, that the applied power
arrows show from the public supply network in direction of consumers within the home. Next,
make sure that voltage L1 is connected to V1, voltage L2 to V2 and voltage L3 to V3. Likewise,
the current sensor at conductor L1 has to be connected to I1, the current sensor at conductor L2
to I2 and the current sensor at L3 to I3..
Attention: If a channel is reversed, the measured values for the active power and active
energies are distorted strongly.
After connecting the lines according to the connection plan the device is ready for operation.
Once the KNX-bus is connected, the “POWER” LED lights up permanently after a short start-up
procedure (about 3 seconds). From that time the device performs measurements permanently. If
not already done the SD card for recording the measurement data has to be inserted.
Below is shown, which relevant parameter related to this example has to be set in the ETS.
In the tab “General” the parameter “Request time and date after bus voltage recovery” should be
set. Otherwise the default values can be adopted. By setting the parameter the Smartmeter
requests once after each restart of the application the current time and date from the bus. This
data must be provided from an other device in via a group address. If no device exists on the
bus, which provides a time then this example can not be applied. The time is needed since the
Smartmeter transmit the measurement values always synchronized with the day time on the
bus, e.g. on the minute or hour. The time is also needed for the timely recording of the
measurement data on the SD card.
Therefore the tab “General” has to be parameterized as follows:
Enertex® Bayern GmbH – Ebermannstädter Straße 8 - 91301 Forchheim - Deutschland - mail@enertex.de
Page 12
Handbuch-KnxSmartmeter-85A-en-3.odt, 2018-10-04 Seite 12 von 69
Figure 5: Settings „General“ Example 1
The settings in the tab “Measurement” can be seen in Figure 6. It is advisable that in the
parameter “Reference current for limit values (x5A)” the security value is entered with which the
lines at the measurement point of the Smartmeter are protected. In this example the reference
value is therefore adjusted to 35A corresponding to the protection fuse of the house connection.
Therefore a parameter with the value 7 is entered in “Reference current for limit values (x5A)”.
This setting results in a viable range of values for the subsequent indication of current and power
limits.
Since only the measurement of three-phase values is relevant in this example, only these are
released in the settings. Otherwise the default values can be adopted. With the default settings
for the SD card recording, all measured values except the harmonics are recorded on the SD
card. With a parameterized recording interval of “15min” each 15 minutes a record of all
measurements (currents, voltages, powers, energy counter, THDs, frequency, power factors,
current and voltage peaks) on the SD card is done. The measurements are written in CSV
format to a file. At the beginning of each new day a new recording file is generated. Thus, the
data on the SD-card are ordered by day to a certain extent. The csv-files can directly be opened
and processed by a spreadsheet program such as Excel, Openoffice Calc or Gnumeric.
Figure 6: Settings „Measurement“ Example 1
In the next tab “Measurement three-phase” can be parameterized, which three-phase values are
to be transmitted on the bus.
Enertex® Bayern GmbH – Ebermannstädter Straße 8 - 91301 Forchheim - Deutschland - mail@enertex.de
Page 13
Handbuch-KnxSmartmeter-85A-en-3.odt, 2018-10-04 Seite 13 von 69
Figure 7: Settings „Measurement three-phase“ Example 1
If, as in this example, the three-phase power shall be displayed on the bus seamlessly, the panel
“Transmit power and current measurements at change” has to be enabled. Then further buttons
are opened, with which this function can be specified. In the panel “Transmit measured values at
change” a percentage rate of 5% is indicated. Thus, a new measured value is transmitted, if the
measured value has been changed by more than 5% with respect to the value last transmitted
on the bus. With this setting the measurement on the bus can be effectively tracked without
which the bus is flooded with unnecessary messages. If the number of messages is still too high
with this settings, then the number of transmitted messages can be reduced by increasing the
percentage value. However, this goes hand in hand that the measured values can be tracked by
the bus with less accuracy. Here a appropriate compromise depending on the fluctuation of the
consumption loads should be found between the deviation of the indication from the current
measurement and the operational demands of the bus. Finally it should be configured, which
measurements are to transmit in cases of changes. Since only the active power is of interest,
only that button is activated.
In the following tab “Energy counter/ Tariff cost counter” from Figure 8 the used counter can be
released. Since in this example only the three-phase consumption and its costs are to be
visualized, only the energy counter “Energy counter three-phase” and the cost counter “Tariff
cost counter 1” is released. Furthermore two other so-called intermediate counter are required in
this example to transmit quarter-hour-consumptions and to transmit daily consumption costs
(=daily cost of electricity). These counters are released as well:
Enertex® Bayern GmbH – Ebermannstädter Straße 8 - 91301 Forchheim - Deutschland - mail@enertex.de
Page 14
Handbuch-KnxSmartmeter-85A-en-3.odt, 2018-10-04 Seite 14 von 69
Figure 8: Settings „Energy counter/Tariff costs counter“ Example 1
In the following two tabs “Energy counter - three-phase” and “Tariff costs counter - three-phase”
no adjustments have to be done. Here the default values are taken.
Now the energy counter in the tab “Intermediate counter 1” is configured to count the quarterhour consumption. For this the “Input counter value of intermediate counter” has to be set to
“Active energy counter (consumption) - three-phase”. The counting interval is set to “15min”.
Furthermore the setting “Transmit counter value before resetting” is enabled:
Figure 9: Settings „Intermediate counter 1“ Example 1
With this configuration the intermediate counter sums up the three-phase energy consumption
each about 15 minutes and transmits this amount on the bus at the end of the interval. After that
the intermediate counter resets and adds the energy consumption again. Thereby the time
intervals are synchronized with the day time, so that the time intervals only start and end at
times XX:00 (=every hour), XX:15 and XX:45. Thus, these counters can also measure
synchronous to other current counters. Finally the 3-phase energy consumption of the last 15
minutes is transmitted cyclically after each quarter of an hour by this parametrization. Thereby
Enertex® Bayern GmbH – Ebermannstädter Straße 8 - 91301 Forchheim - Deutschland - mail@enertex.de
Page 15
Handbuch-KnxSmartmeter-85A-en-3.odt, 2018-10-04 Seite 15 von 69
the energy consumption of intermediate counter 1 is transmitted by the group object “Energy
counter-previous value” on the bus. The energy consumption is transmitted in the unit Wh.
Similarly, the intermediate counter 2 is configured to transmit each daily energy costs at the end
of a day on the bus. For this purpose “Tariff cost counter (consumption) - tariff 1” is used as
input value in intermediate counter 2. The counting interval is set to “24h” Furthermore the
adjustment “Transmit counter value before resetting” is enabled again:
Figure 10: Settings „Intermediate counter 2“ Example 1
The energy costs which have been summed up over the day are then transmitted on the bus at
the end of a day via the group object “Costs counter-previous value”of intermediate counter 2.
The transmitted value represents the energy costs in cent.
Finally a tariff must still be specified to calculate the costs. Thereby “Tariff 1” is released in the
tab “Tariff”. Then the parametrization of tariff 1 is done in tab “Tariff 1”:
Figure 11: Settings „Tariff 1“ Example 1
In the panel “Rate” the electricity rate is given in 0.01 ct/kWh. This means for a given current
rate of e.g. 30ct/kWh a value of 3.000 has to be specified here. Furthermore it has to be
specified here when the tariff shall be valid. In this simple example only one electricity tariff
should be configured, which is valid around the clock. For this purpose the entry “always active”
is selected in the panel “Tariff changeover tariff 1”.
The parametrization presented in this section causes the Smartmeter to transmit the following
group objects cyclically: “Energy counter-previous value” (ID 105), “Costs counter-previous
value” (ID 115), “Active power” (ID: 64).
If these group objects are linked with group addresses, then they can be very easily visualized in

Finally it should be explained on the basis of this example, as the already existing current
counter of Figure 4 can be synchronized with the Smartmeter. For this purpose the counter
value from the existing current counter shall be entered on the register “Active energy counter
(balance) - three-phase”. This can be performed using the ETS. Thereby the “Writing”-flag of the
group object “Active energy counter (balance) - three-phase” has to be set. After the group
object has been linked to a group address the application must be re-recorded. Now the counter
value of the existing current counter can be written to the corresponding group address in the
ETS group monitor. It should be noted that the value has previously to be converted from kWh
into Wh. If necessary, the “Writing”-flag of the corresponding group object can then be removed
again.
Example 2:
Bidirectional Counter for
Photovoltaics
In the second example the use of the Smartmeter as a bidirectional counter for a residential
building with a PV-system will be demonstrated. The daily energy costs and the daily tariff for the
PV-system are to be displayed on the bus. Thus, the energy costs and energy yields can be
visualized, for example, over the last 6 months on a chart. In addition the progress of the energy
fed by PV, the progress of the energy provided by the network and the balance of both are to be
visualized over the last 24 hours.

Furthermore it is shown in this example, as a simple load management can be implemented
using a single threshold. The load management shall contribute to the energy generated in the
PV-system is preferably used to supply their own consumer loads rather than feeding into the
net (for a relatively low feed-in rate).
In this example the following topics are treated: bidirectional counter, tariff counter, intermediate
counter and limit values.
The installation of the Smartmeter in this example is 3-phase in the main connection of the grid.
In general the current sensors are installed downstream the current counter of the energy
supplier. Likewise, the voltage can be measured directly downstream the current counter:
Figure 12: Connection of the Smartmeter in a residential building with PV-system
The example is irrespective of whether the PV-system is connected to the network single phase
or three phase.
Below is shown which relevant parameters are to set in the ETS relating to this example.
In the tab “General” the parameter “Request time and date after bus voltage recovery” should be
set. Otherwise the default values can be used:

Figure 13: Settings „General“ Example 2
The settings in the tab “Measurement” can be seen in Figure 14. It is advisable that in the
parameter “Reference current for limit values (x5A) the security value is entered with which the
lines are protected at the measurement point of the Smartmeter. In the present example the
reference value is set to 35A corresponding to the protection fuse of the house connection.
Therefore a parameter with the value of 7 has to be entered in “Reference current for limit values
(x5A)”. This setting results in a variable range of values for the subsequent indication of current
and power limits.
Since only the measurement of three-phase values is relevant, only these are enabled in the
settings. Otherwise, the default values can be used:
Figure 14: Settings „Measurement“ Example 2
In the next tab “Measurement - three-phase values” the limit value of the three-phase active
power for load management is parametrized. In principle the concept of load control is to work
as follows:
If currently more energy is generated in the PV system than is consumed by the consumer loads
at home, then the Smartmeter will measure a negative three-phase active power. Then energy is
fed into the grid. In the opposite case the measured active power would be positive. The load
management is to be designed so, that only the excess energy from the PV-system will be used
for additional consumer loads. Therefore corresponding consumer loads have to be switched on
as soon as the active power reaches a certain negative value. This threshold is determined on
-966W in the example. If the active power becomes positive again, the consumer loads will be
switched off again. Therefore this threshold is set to 0W. Between these two thresholds a buffer
zone should be parametrized so that consumer loads do not continuously switched on or off.

This is realized by the hysteresis function.
With the following parametrization this concept can be implemented. The limit value for the
three-phase active power is set to “-20” (=-2%). This corresponds to the following power:
The value 35A corresponds to the parametrized reference current. The term
is required
to convert the reference current in a three-phase reference power. The value for the hysteresis
is set to “-40” (=-4%). This corresponds to the following power:
With the limit values and the hysteresis the following thresholds arise:
• Under threshold:
• Upper threshold:
If the three-phase active power reaches the upper threshold of -966W, the value 1 is transmitted
to the group object “Active power limit message” (ID:66). In contrast, if the three-phase active
power reaches the lower threshold of 0W, the value 0 is transmitted to the group object “Active
power limit message” (ID:66). Exactly these values of the group object “Active power limit
message” (ID:66).are needed for switching on/off a consumer load. So the “switching”-group
object of the switching actuator of a consumer load has to be linked to the group object “Active
power limit message” (ID:66) of the Smartmeter.
However, the connected consumer load has also be suitable for this automatic enabling or
disabling. Possibly suitable consumer loads are for example electric heatings, heat pumps,
boiler, cooling aggregates or charging devices.
A much less critical method than the automatic switching of consumer loads is just to have the
energy excess displayed. Thus the residents are signaled by a green signal lamp at which time
the current is cheap (green signal lamp on) or at which time the current is expensive (green
signal lamp off). For this purpose the group object “Active power limit message” has to be linked
to the group object of the switching actuator of the signal lamp.
For parametrization of the load management the following values have to be selected in the tab
“Measurement- three-phase”:
Figure 15: Settings „Measurement - three-phase“ Example 2
In the next tab “Energy counter/Tariff cost counter” in Figure 16 the applied counter are

released. Since in this example only the three-phase consumption and its costs are to be
visualized, only the energy counter “Energy counter - three-phase”, the cost counter “tariff costs
counter 1” and “Tariff costs counter 2” are released. Furthermore 3 intermediate counter are
required to represent the energy consumption, the energy supply and the balancing energy over
the course of one day on the bus. Two other intermediate counter are used to represent the
daily energy supply costs and the daily compensation for electricity fed into the grid:
Figure 16: Settings „Energy counter/Tariff cost counter“ Example 2
In the following two tabs “Energy counter - three-phase” and “Tariff cost counter - three-phase”
no settings have to be made. Here the default values are used.
In the tab “Intermediate counter 1” the energy counter is configured to count the energy delivery.
For this purpose the “Input count value of the intermediate counter” has to be set to “Active
energy counter (consumption) - three-phase”. The count interval is set to “15min”. Furthermore
the setting “Transmit counter value before resetting” is enabled:
Figure 17: Setting „Intermediate counter 1“ Example 2
With this configuration the intermediate counter sums up the delivery of three-phase energy, that
is only the energy flux in positive power flux direction, each about 15 minutes and transmits this
sum on the bus at the end of the interval. After that the intermediate counter resets and starts
Enertex® Bayern GmbH – Ebermannstädter Straße 8 - 91301 Forchheim - Deutschland - mail@enertex.de
Page 20
Handbuch-KnxSmartmeter-85A-en-3.odt, 2018-10-04 Seite 20 von 69
again summarizing the delivery of energy. Thereby the time intervals are synchronized with the
day time, so that the counting intervals only start and end at times XX:00 (=every hour), XX:15
and XX:45. Finally the 3-phase energy delivery of the last 15 minutes is transmitted cyclically
after each quarter of an hour by this parametrization. Thereby the delivery of energy of
intermediate counter 1 is transmitted via the group object “Energy counter-previous value” on
the bus. The delivery of energy is transmitted in unit Wh.
Similarly the “Intermediate counter 2” is configured to transmit the energy fed into the grid every
15 minutes on the bus:
Figure 18: Settings „Intermediate counter 2“ Example 2
By selecting the counter value “ Active energy counter (generation) - three-phase” only the
energy flux is counted in negative power flux direction.
Finally in “Intermediate counter 3” the counter is configured for the balanced energy:
Figure 19: Settings „Intermediate counter 3“ Example 2
In contrast to the “Active energy counter (consumption)” and “Active energy counter
(generation)” the “Active energy counter (balance)” counts all the time. Its counter value can
increase or decrease, whereas the consumption counter only increase and the generation
counter only decrease. With the balancing counter neither the energy costs or the compensation
can be calculated. Nevertheless the course of the day of the balancing counter shall be
recorded, as seen directly from this, to what extend the purchase of an additional battery storage
for solar energy would be useful.
The “Intermediate counter 4” is used to calculate the daily energy delivery costs. As a counter
value it has to be used a “Tariff costs counter (consumption)”. Thus, this counter only counts,
when energy flows in positive power flux direction. As later in the example the delivery rate for
the current is deposited in the rate of tariff 1, the “Tariff costs counter (consumption) - tariff 1”
has to be used as a counter value:
Enertex® Bayern GmbH – Ebermannstädter Straße 8 - 91301 Forchheim - Deutschland - mail@enertex.de
Page 21
Handbuch-KnxSmartmeter-85A-en-3.odt, 2018-10-04 Seite 21 von 69
Figure 20: Settings „Intermediate counter 4“ Example 2
The counting interval is configured to 24 hours. Thus, the energy delivery costs are summed up
each over a day and transmitted to the bus via the group object “Cost counter-previous value” of
intermediate counter 4 at the end of the day. The transmitted value represents the daily energy
delivery cost in cent.
Similarly, the “Intermediate counter 5” is used to sum up the daily compensation and to transmit
on the bus. To calculate the compensation only the energy flux in negative power flux direction
may be used. Therefore a “Tariff cost counter (generation)” is necessary here, which only counts
on negative power flux direction.
Moreover this costs counter shall use the rate of tariff 2. In this tariff the compensation will be
specified ct/kWh in a later time. Therefore “Tariff cost counter (generation) - tariff 2” is selected
for the counter value:
Figure 21: Settings „Intermediate counter 5“ Example 2
As already mentioned, the rates for current delivery and for current feeding have to be provided
for the two cost counters. The specification have to be done under the heading “Tariff”. The
“Tariff 1” is used for the energy delivery tariff and the “Tariff 2” for the feed-in tariff. Therefore
these both tariffs are to release in the tab “Tariff”.
In the tab “Tariff 1” the current rate is indicated to 0.01 Cent/kWh. This means with e.g. a current
rate of 30ct/kWh a value of 3000 has to be specified here. Furthermore it has to be parametrized
here, when the tariff is to apply. In this simple example only a single current tariff should be
configured, which is valid around the clock. For this purpose the selection in “Tariff changeover
tariff 1” is selected to “always active”:
Enertex® Bayern GmbH – Ebermannstädter Straße 8 - 91301 Forchheim - Deutschland - mail@enertex.de
Page 22
Handbuch-KnxSmartmeter-85A-en-3.odt, 2018-10-04 Seite 22 von 69
Figure 22: Settings „Tariff 1“ Example 2
Similarly, the feed-in tariff is specified in the panel rate of “tariff 2”. To count positive income a
negative rate may be indicated here. In this case the active energy counter (generation) - threephase, which always contains, by definition, a negative value, is multiplied by a negative rate. It
results in a positive yield, which, for example, represents the yield of a PV-system. Therefore the
entering of the feed-in compensation of 11.56ct has a negative sign:
Figure 23: Settings „Tariff 2“ Example 2
Generally also the feed-in rate is not depending on the time of day. Therefore the tariff switching
is deactivated by selecting of “always active”.
The parametrization which is presented in this section causes the Smartmeter to transmit the
following group objects: "Energy counter-previous value" for the intermediate counter 1 (ID:
105), "Energy counter-previous value" for the intermediate counter 2 (ID: 113), "Energy counterprevious value" for the intermediate counter 3 (ID: 121), "Cost counter-previous value" for the
intermediate counter 4 (ID: 131) and "Cost counter-previous value" for the intermediate counter
5 (ID: 139).

effective value is always positive, because it has no direction.
Active power is the real consumed energy per unit time. It may
be positive (during Energy consumption) or negative (during
Energy generation). Refer to Figure 24.
Reactive power is the exchanging energy between capacitance
and inductance . It can be positive (inductive) or negative
(capacitive). See also Figure 24.
Apparent power is the value resulting from active and reactive
power. This is always positive. With the apparent power the
utilization of resources such as cables or transformers can be
assessed.
Instantaneous power factor.
The power factor (cos φ) is the ratio of active power to apparent
power. The sign is defined in Figure 24.
Harmonics (0. to 50.) of the voltage . Since the recording of the
test series takes a minute, the values correspond to the
harmonics one minute ago.
When transmitting a complete spectrum, four single messages
with each 14 Bytes are transmitted. In them all the harmonics of
a voltage are coded as follows:
The first byte corresponds to an index of a harmonic; i.e. an
integer number between 0 and 50. The second byte is the
amount of the harmonic corresponding to the index from the first
byte. The following 12 bytes correspond to the amount of the
next 12 harmonics. Thus, the values of 13 harmonics are
transmitted in a 14-byte message. To exploit the range of values
of a byte in an optimal way, the values of a byte are again
encoded.
For decoding, a byte needs to be interpreted as a positive
integer x (i.e. between 0 and 255) and according to the formula
it has to be converted into a corresponding value V which is the
ratio of the corresponding harmonic to the fundamental.

In this counter only the generated energy, i.e. the energy flow in
negative direction of the power count arrow is counted.
The value represents the generated energy and is always less

In this counter the absolute value of the reactive power is
counted. The shown value is the absolute value of the reactive

s32 in ct Currently accounted costs in the corresponding tariff. This value
indicates the balance between consumption and generation
costs. The value can be positive or negative. If the value is
negative, the absolute value corresponds to a compensation.
s32 in ct Current costs for the consumed energy in the corresponding
tariff.
s32 in ct Current costs for the generated energy counted in the
corresponding tariff.
These costs are (at positive tariff-rate) negative and therefore
correspond to a compensation. The counter is used to a certain
extend for counting the compensation for the generated energy
in the corresponding tariff.

General Function Concepts
Cyclical transmitting
Measured values and counter readings can be transmitted cyclically on the bus. The function is
used as for equidistant representation of a measured value on the bus or in a diagram and thus
represents a sampling of the measured value.
When activated, the corresponding values are transmitted on the bus in a cycle time, which can
also be parametrized by ETS. The first transmission is carried out shortly after a restart of the
application. From this moment the value is transmitted cyclically. The transmissions are not
synchronized with day-time in this case.
If the cycle time 0 is given in the ETS, the value will never be transmitted cyclically.
Transmit at Change
Measurement values and counter readings can be transmitted on the bus after a change. The
function is used for a complete representation of a measurement on the bus or in a diagram.
Since the measured values are only transmitted after a change this can be done with a minimal
strain of the bus. On the bus a maximum of one change of a measurement value per second
can be transmitted.
In the ETS it can be parametrized, at which change the value on the bus is retransmitted. This
value is indicated in percentage. The first transmission is always performed shortly after a restart
of the application. From this point a new value is transmitted in each case, if the measured value
has changed by more than the set percentage value relative to the value last transmitted on the
bus. It is independent of whether the value last transmitted has been transmitted due to the
function “Transmit cyclically”, “Transmit at change” or “Request measured values”.
Figure 24: Representation of the counter quadrant
Attention: In the setting “Transmit at change” it is to be noted that the last transmitted measured
value can vary from the actual current measurement value by up to the percentage value which
is parametrized in the ETS respectively. With the help of the adjustable percentage a suitable
compromise between the deviation of the indication from the current measured value and the
bus strain can be found.
If in the ETS the percentage is specified to 0% the value will never be transmitted on a change.

Bidirectional Counter
P+
The device can be used as a bidirectional counter and as a balancing counter at the same time.
Bidirectional counter are always required when at the measurement point of the counter an
energy flow occurs in both directions and in addition the energy flow in one direction is different
billed as the energy flow in the opposite direction. This is the case e.g. during the operation of a
PV-system in a residential building. If the Smartmeter is installed at the house connection line
then the registers for both directions must be used.
For this purpose each energy counter of the Smartmeter (i.e. active energy counter-channel 1,
active energy counter-channel 2, active energy counter-channel 3 and active energy counter
three-phase) has three registers. One register for the consumption (group object “Active energy
counter (consumption)”), one register for the generation (group object “Active energy counter
(generation)”) and one register for the balance (group object “ Active energy counter (balance)”).
The register for the consumption only counts, when an energy flow occurs in positive power flow
direction. The register for the generation only counts, when an energy flow occurs in negative
power flow direction. The register for the balance counts in both cases.
The power arrow direction is determined by the orientation of the current sensors. The power
arrow which is glued on the current sensors
Typically the current sensors are mounted so that the power arrow is oriented from the energy
source to the energy consumer load. This means that in the example of the installation of the
counter at the connection line of the residential home the current sensors are oriented so, that
the power arrow shows from the national grid to the consumer loads in the residential home. If
energy is currently consumed in the house, then the consumption counter counts in that case. If
in the house energy is never generated, the generation counter is always zero. If in the house
energy can be generated, e.g. by a PV-facility, then different scenarios are possible:

of the energy provider.
The “Active energy counter (balance)” also counts in the first both scenarios. For the charge of
the energy delivery only the value of the “Active energy counter (consumption)” is used.
However,for the charge of the compensation only the value of the “Active energy counter
(generation)” is used.
The “Active energy counter (generation)” is by definition always negative, since it is a negative
energy flow related to the power count arrow. With this definition it is always :
Active energy counter (balance) = Active energy counter (consumption) + Active energy counter
(generation)
Just as the energy counters each tariff costs counter has three registers for consumption,
generation and balance. They are treated in the same way, i.e. during an energy consumption
the tariff cost counter counts in the group object “Tariff costs counter (consumption)”, during an
energy generation the tariff cost counter counts in the group object “ Tariff costs counter
(generation)” and the tariff cost counter in the group object “ Tariff costs counter (balance)”
always counts.
Thus with regard to the costs separate registers are also used for each count direction. To count
a compensation directly in a cost counter, the feed-in tariff in tariff 1 can be specified. In the
group object "Tariff costs counter (generation)” for tariff 1 one can directly read the accumulated
compensation. In order that the compensation in the counter appears positive, a negative rate
(=compensation) has to be specified in the panel for the rate of tariff 1. If also energy delivery
costs are to be counted , the delivery rate of the supplier of electric energy can be indicated in
tariff 2. In the group object "Tariff costs counter (consumption)" for tariff 2 the accumulated
current costs can be read directly. The group object "Tariff costs counter (consumption)" for tariff

2 can be ignored in this case.
Intermediate Counter
Intermediate counter are used to display energy consumptions and energy costs on the bus or in
a diagram.
An intermediate counter accumulates (sums) in each case a selectable count value over a
configurable time interval. This counter value may be an energy consumption, an energy
generation, an energy cost value or a compensation for electricity fed into the grid. The counter
value and the counting interval are configured in the ETS. The counting interval of the
intermediate counter is thereby synchronized with the daytime, so that, for example, an
accumulation of energy values for one hour always starts on the hour.
In detail an intermediate counter operates as follows:
After restarting the application the selected counter value is accumulated (summed) in the
current value of the intermediate counter, that is group object “Current value”. This accumulation
is carried out up to the first interval limit. Since the interval limits are synchronized with the
daytime, one time has to be transmitted to the corresponding group object “time” of the
Smartmeter (i.e. once after the restart of the application). To do this automatically, the function
"Request time and date after bus voltage recovery” can be used.
Attention: If the time is not transmitted to the Smartmeter, the interval limits cannot be detected
and the function of the intermediate counter (unless a manual trigger is used, see section below)
can not be used.
Handbuch-KnxSmartmeter-85A-en-3.odt, 2018-10-04 Seite 27 von 69
Once an interval limit is reached, the accumulated counter value is written from the group object
"Current value" into the group object "previous value". Thereafter the counter in the group object
"Current value" is reset to zero and the accumulation for the next interval starts again. If the
function “Transmit counter value before resetting” is activated, then at the interval limit the
counter value of the last count interval in the group object “previous value” is transmitted on the
bus. This feature allows for example the energy consumption of the last count interval in the
group object “previous value” to be transmitted on the bus at the end of each count interval. This
value can then be used to show the energy consumption over one day.
The intermediate counter additionally offers the option to set a count interval with a trigger. Thus,
it can be used without time. The function is activated by selecting of "By trigger object" in the
parameter count interval. As a trigger object the group object "Reset counters" is used. If in this
case the value “ON” is transmitted to the group object then this has the same effect as the
reaching of the interval limit in the case above. Thus, for example, it is possible to start a
consumption measurement by pressing a key button. By re-pressing the key button the energy
consumption, which is measured between the two manual operations, is transmitted on the bus.
Tariff Costs Counter
Tariff costs counters allow a representation of energy costs and energy yields on the bus or in a
diagram.
In contrast to the energy counters, which count energy in Wh, the tariff cost counters count the
energy costs in cent. Therefore the energy costs and accordingly energy yields have to be
indicated in 0.01ct/kWh. These costs and yields are deposited in up to three tariffs, which for
each tariff a rate and a time frame can be specified. Furthermore each tariff has three group
objects for tariff costs counter wherein in each case the costs for the active energy counter
(balance) - three-phase, active energy counter (consumption) - three-phase and active energy
counter (generation) - three-phase are counted. It should be noted that only the costs for threephase can be counted. The cost for the consumption in a single phase,for example, can not be
calculated in the Smartmeter.
A tariff costs counter counts each if the tariff is currently active and also the underlying (i.e.
either for balance, consumption or generation) three-phase energy counter counts. Due to the
set time frame for a tariff it can be determined, if it is currently active. It is also possible that
several tariffs are active at the same time. Then they count parallel.
To count positive yields, a negative rate can be specified. In this case the active energy counter
(generation) - three-phase, which always contains, by definition, a negative value, is multiplied
by a negative rate. The result is a positive yield which represents for example the yield of a PV-

system.
Attention: If a tariff time switch is parametrized for a tariff and the time has not been transmitted
to the Smartmeter then the time frames for the tariffs can not be detected. In this case the tariff
is never active.
Tariffs can also be activated by trigger objects. The function is activated in the parameter “Tariff
changeover” by selecting “via triggering objects”. As trigger objects the group objects Trigger
(Tariff start)" and "Trigger (Tariff stop) can be used. If in this case the value “ON” is transmitted
to the group object “Trigger (Tariff start)", then the tariff is active. By transmitting the value “ON”
to the group object "Trigger (Tariff stop)" the tariff is deactivated again. In connection with the
limit value of the intermediate counter for example the costs of a volume tariff can be found. So
tariff 1 (low level tariff) can be stopped when a limit value for the three-phase energy counter
(consumption) is exceeded and tariff 2 (high level tariff) can be started. With the help of a
second threshold which has to be set to 0Wh tariff 2 can be stopped and tariff 1 can be
reactivated. With this configuration the two intermediate counter finally only have to be reset at
that time at which the volume will be newly “refreshed”. This can be done by a manual trigger.
In addition to the triggering of tariffs with the trigger objects the tariff can also be selected via the
group object “Tariff changeover”. Thereby “By trigger objects” has to be selected also in the
parameter “Tariff change”. Henceforward by transmitting the values 1, 2 or 3 the same tariff that
is tariff 1, tariff 2 or tariff 3 can be activated. If a tariff is enabled by these functions, then the
other both tariffs are disabled.
If the tariff selection by triggering objects is enabled then also the parameter “Tariff after bus
voltage recovery” is important. Here it can be parametrized which tariff is valid after restarting an
application. When selecting “as before” the device activates the same tariffs as last before
restarting.
If there is no tariff switching, the parameter “Tariff changeover” can be selected “always active”.
Then this tariff is always active and time is also not required. It is also possible to parametrize
two or three tariffs as always active. Then the current delivery costs can be counted in tariff
counter of tariff 1 and the compensation of a PV-system can be counted in tariff counter of tariff
2. For this purpose the electricity rate must be specified in tariff 1 and the compensation has to
be specified in tariff 2.
Furthermore the device offers the option to adopt the rate of a tariff from the bus via the group
object “Rate (0.01 ct/kWh)”. With this possibility the electricity rate can be easily adjusted via the
bus in case of a electricity rate change.
Preset of a Counter
Each counter can be preset with an energy value or rate. Thus, a count of the Smartmeter can
be matched with an existing counter. This allows easy control of the existing counter.
To preset a count only the “Writing”-flag of the corresponding group object of the counter has to
be set. Thereafter the counter can be rewritten via messages from the ETS. The written value
are given in Wh (not kWh). If necessary the “Writing”-flag of the corresponding group object can
then be removed again.
Message of limit values
In the application limits can be set for different measurement values. When these limits are
exceeded or fallen below corresponding messages are triggered on the bus. With this method
overloads, over voltages, under voltages, voltage drops, consumption peaks but also critical
values related to the grid quality can be reported on the bus. These messages can be used for
example for alarm messages or directly to initiate appropriate counteractions.
If a limit value is exceeded, the value 1 is transmitted to the corresponding group object “Limit
message”. However, if the limit value is fallen below the value 0 will be transmitted to the same
group object. The limit values are usually specified as absolute values. However, in the case of
currents and powers the limit values are indicated as percentages with respect to a reference
value. Thus, alarm messages such as "Alarm when exceeding 90% of the maximum allowable
current" can be parametrized literally. The value of the “maximum allowable current” has to be
parametrized in the parameter "Reference current for limit values" of the tab “Measurement”. It is
advisable that each of the backup value is used as a reference current with which the cables are

secures at the measurement point of the Smartmeter. That means during the installation of the
Smartmeter for a 35A main fuse the reference value would be parametrized to 35A. The
reference value for the power limit is also determined by this parameter.
The reference value for a single-phase power limit is determined by the formula “Reference
current x 230”, the reference value for a three-phase power limit is determined by the formula
“Reference current x 230 x 3”. This means a parameter value of 7 would correspond to a
reference current of 35A, a single-phase reference power of 8050W and a three-phase
reference output of 24150W.
For the limit values of active and reactive power a hysteresis can also be set. This prevents a
flood of messages during a fluctuation of a measured value around the limit value (With limits
without hysteresis at most one message per second is transmitted at the bus in extreme cases).
Also the hysteresis is indicated in percent with respect to the above-mentioned reference value.
The setting of a hysteresis has the effect, that the value 1 is not transmitted to the limit value
until the measured value exceeds the value "parametrized limit value + 1/2 x parametrized
hysteresis value". Similarly, the value 0 is not transmitted until the measured value falls below
the value " parametrized limit value - 1/2 x parametrized hysteresis value".
Attention: If negative limit values are used at the power limits then by definition the values for
the hysteresis have also to be selected to be negative. In addition it should be noted that in case
of a negative limit value the value 1 is transmitted if the measured value exceeds the limit as an
absolute value. Similarly the value of 0 is transmitted if the measures value drops below the limit
as an absolute value.
Furthermore, limit values for counters can be realized. However, this is only possible for the socalled intermediate counter. As described in section “Intermediate Counter” an intermediate
counter has two group objects, of which the so called object "Energy counter-previous value"
always include the counter value of the last counting interval whereas the group object "Energy
counter-current value” is reset at the end of the counting interval and then again starts to count.
Within the counting interval, therefore, only the counter of the group object "Energy countercurrent value" counts. Hence the threshold is applied to this group object. Just as the object
"Energy counter-current value" also the object "Limit Message" of the intermediate counter is
reset at the end of the interval. This allows a transmission of the value 1 to the group object
"Limit message" in each count interval when a limit is exceeded, regardless of whether the limit
has been exceeded in the previous count interval.
The limits for the intermediate counters and the powers can also be changed by the bus via
corresponding group objects. Thus, a limit value, parametrized in the ETS can be overwritten by
that value, which has been transmitted to the group object. This allows, for example, the
individual setting of a limit value depending on specific conditions, for example in the daytime a
higher limit value can be used than in the night.
Recording on the SD card
Using the SD card measured data can be recorded. By the ETS the recording mode and the
recording interval can be parametrized. The recording modes are as follows:

By default the recording mode is set to "All measurements without harmonics". The recording
interval can be configured in steps 1min, 5min, 15min, 1h, 12h, and 24h.
After starting the application the recording to the SD-card starts. During the recording start a
new text file in csv-format is created on the SD-card, respectively. The file name is automatically

generated from the recording mode and the recording day. A new recording file on the SD-card
is created for each day. In the first two lines of the log file it is a legend with name and unit for
the respective measured value of the corresponding column. the following lines contain the
recorded data. Each line starts with a time stamp indicating the time of recording of the
measured data record. The values in the data set represent the measured values in the previous
recording interval.(i.e.time to time stamp).
The recorded values are to be distinguished as follows:

Thereby the correct time and the correct date is shown in the time stamp, once (i.e. once after
the restart of the application) a time has to be transmitted to the group object “Time” and a date
has to be transmitted to the group object “Date” of the Smartmeter. To do this automatically after

a restart of the application the function "Request time and date after bus voltage recovery" can
be used. If a time and a date has been transmitted to the Smartmeter then the recording is made
each synced with the time of the day, that means at a recording interval of 15 minutes the
recording is carried out in each case to the minute XX:00 (= every hour), to the minute XX:15, to
the minute XX:30 and to the minute XX:45.
If no time has been transferred to the Smartmeter by bus, then the clock is set to 00:00 when the
application starts and the first recording is performed after the elapse of the first recording
interval.
If at a time of recording no SD card is inserted then the recording data are lost for this time,
since the recording is not additionally buffered. If at the start of the application no SD card is
inserted, then the recording do not start until the first time of recording after insertion of the SD
card.
Attention: When the Smartmeter writes data to the SD card, the "POWER / SD-WRITE" LED
lights up red while writing. To prevent loss of data on the SD card, the SD card may not be
removed during the write operations.
Adjusting the real-time
clock without bus access
At a Smartmeter with RT option, the internal time of the smart meter can also be adjusted
without a KNX bus using only an SD card. Usually, the adjustment of the time is only necessary
after a few years, since the deviation of the internal time to the actual time increases only by a
maximum of one minute per year. The changeover from winter to summer time or from summer
to winter time is automatic, so there is no need to intervene manually. Likewise, leap years are
automatically taken into account in the date.
Handbuch-KnxSmartmeter-85A-en-3.odt, 2018-10-04 Seite 31 von 69
To readjust the time with an SD card, you must first create a text file with the date and time on it.
This text file must be created with the file name "DATETIME.TXT" (uppercase letters must be
used!). Then the file must be saved using a simple text editor, such as Editor or Wordpad. The
time to be set in the form of the time stamp, which is also used in the recording files, must now
be entered into the file. That For example, the text "2016-05-10-14:23:05" for May 10, 2016 and
the time of day of 14:23 and 5 seconds. To ensure that the time is interpreted correctly by the
Smartmeter, you must ensure that the time is entered exactly according to the specified pattern
and that no characters other than numbers, hyphen and colon are used. The SD card must now
be inserted into the Smartmeter during operation. As soon as the SD card is inserted, the time
stored on the SD card is taken over. The correct acceptance of the time is confirmed by the
yellow "POWER / SD-WRITE" LED lighting up for 2 seconds and then turning green again. To
set the time to the second with this method, the text file must specify a time in the future. The SD
card must then be inserted into the Smartmeter at exactly the specified time. If the time has
been taken over correctly, the file "DATETIME.TXT" will also be deleted automatically.
A smart meter with the RT option has an internal CR2032 lithium coin cell to maintain the clock
during power outages. The built-in battery lasts about 7 to 10 years if the device was not
disconnected from the 24V power supply for more than one year. If, after 7 to 10 years, there is
a large deviation in the time (more than 10 minutes), the internal battery must be replaced. The
exchange of the battery is only possible by opening the housing. To do this, the housing cover
must first be removed. This is snapped on the lower housing part and can be levered with a
screwdriver on the two provided notches on the cover. If the cover is removed, then the two
housing halves can be pulled apart. Finally, the lithium button cell in the battery clip can be
replaced.

intermediate counter is a counter that
automatically resets after a certain time. The final
counter value before resetting is written to the
group object “Intermediate counter - previous

The count interval can be selected here. After the
selected time the intermediate counter is reset.
Before resetting the current intermediate counter
reading is copied to the group object of the
previous value. The reset time instances of a
intermediate counter are synchronized with the
time, that is e.g.at time interval of 1 min the
counter is reset each when the second indicator
of the clock is 0. At 15 min counting interval the
counter value is reset corresponding to each
synchronized 1/4 hour, that is e.g. 00:00, 00:15,
00:30, 00:45.
Note: Since intermediate counters are
synchronized with the time, the counter readings
only reset at the defined times (and automatically
transmitted on the bus), if a time has been
transmitted to the group object “time” of the
Smartmeter.
If the value is set “on trigger object” then the
corresponding object is released. If in this case
