Home

Main menu

The main menu can be found in the lower part of the window. Here you can choose between the
items Home, Compare, Chart, Overview and Settings.

Time window

You can choose between the time periods Day, Week, Month or Year. In the calendar you can pick
the desired time. The present day is shown in boldface. Below the calendar you can choose the unit
in which the values are shown, possible units are costs (in the configured currency), energy
consumption (in kWh) or emission (in CO2). The user interface reloads automatically after clicking
a button.

Main window

You can show or hide the views Consumption, History, Overview, Target performance and Budget
by clicking on the respective buttons. Multiple views can be selected at the same time.

• Consumption: The three doughnut charts show how the consumption is distributed to the 3
phases, to base load and active load and to the different consumption classes (heat, cooling,

washing, media and light and “not assigned”).

• History: The bar chart shows the energy consumption within the selected time period in the
next smaller unit. Clicking on one of the bars shows the bar chart in the next smaller unit.

• Overview: The left column shows the total consumption within the selected time period and
the minimum, maximum and mean within this period. The right column shows the currently

1

measured values for the total power and the individual phases. The user interface reloads
automatically every 3 seconds.

• Target performance: In the chart, the target value for the selected time period is shown in
green and the actual consumption is shown in red. The target value is calculated as monthly

advance payment minus the consumption in the current month up to now (until 11:59 pm of
the previous day).
When you move the mouse over the chart, a small pop-up window opens in which the target
value, the consumption and the difference between these two values is shown for the
respective points in time.

• Budget: The upper part of the graphics (in advance payed power per hour and tachometer)
refers to the current consumption and is independent of the settings in the time window.

◦ In advance payed power per hour: The power which is payed in advance for an hour

(=monthly advance payment / (number of days in the month * 24 hours * price per
kWh)).

◦ Circular gauge: The gauge reaches from 0 kW to twice the hourly advance payment, so

that the hourly advance payment is exactly in the middle of the gauge.
The red pointer shows the power which is currently measured. If the pointer is right of
the middle, the currently measured power exceeds the advance payment.

◦ Remaining advance payment: The calculation of the remaining advance payment

depends on which time period is selected:
▪ Selection day: remaining advance payment = target value / number of days

remaining in the current month

▪ Selection week, month or year: the remaining advance payment is the advance

payment for the selected time period

◦ Linear gauge: The green part of the gauge reaches from 0 kWh to the value of the

remaining advance payment (2/3 of the gauge). The part right of this value is shown in
red. The green bar below shows the consumption in the selected period (until now).

Compare

Time window

As in the other menus, you can choose between the time periods day, week, month and year in the
calendar. In the upper and lower calendar you can select the two time periods you would like to
compare. As default values the current day and the same day in the previous week are preselected.
Below the calendar you can choose the unit in which the values are shown.

Main window

• Bar chart: The chart shows the energy consumption (resp. the costs or the CO2 emission)
within the two selected time periods in the next smaller unit. The bars referring to the first

time period are shown in red, the grey bars belong to the comparison time period. Clicking
on one of the bars opens the chart in the next smaller unit.

• Consumption: The table shows the total consumption and the average, maximum and
minimum values together with the time of their occurrence for the two selected time periods.

The last column shows the differences between the two time periods.

Chart

Main window

In the main window there are the tabs chart and pattern, further tabs are opened upon viewing
patterns.

In the tab chart the energy consumption can be shown for a maximum time period of 24 hours. Per
default the energy consumption of the current day is shown. When you move the mouse over the
chart, a small pop-up window opens which shows the time and the power measured at this point in
the chart.

Functions of the tab chart:

• Phase selection: In the drop down menu in the upper right part of the main window, you can
choose between the three phases. When “All 3 phases” is selected, the sum of the three

phases is shown.

• Zoom: With the time scale below the chart one can zoom into parts of the chart and out
again. Alternatively, one can also zoom into the chart by clicking on a start and end time

directly in the chart.

• Pattern creation: In order to create a pattern, continue zooming into the chart until you
reduced the view to the desired part. Then click on the button “Create pattern” below the

time scale and scroll down. Here you can fill in the fields Name, Category and Phase for the
pattern. Choose “mobile appliance” if the pattern belongs to a device that can be run on
different phases (e. g. in different rooms).
When you choose a section for pattern creation it is important, that this section contains both
the switching-on and the switching-off of a certain device. If you want to create a pattern for
the recognition of your washing machine, for example, you should choose the section such
that the complete washing procedure is contained. For switching devices like e. g. the
