2.1 ZHOT101 - ZigBee Occupancy, Temper a t ure & Light Sensor
The multi sensor enables you to detect movement and light as well as mea s uring temperature.
The sensor is batter y powered and can be m ounted in four differ ent ways: flat on the wa ll, flat on the
ceiling, in the corner (using a 45° bra c ket), or standing (on a sh e lf, table, or similar).
The sensor has 3 ZigBee end points, one for each sensor. The Occupancy end point contains 2 logic
modules that combines’ Occupancy with temperature and light sensor. Each end point can be used
separately. Standard ZigBee ZCL “Configu r e R epor ti ng” on change and on time is supported.
2.1.1 Occupancy

Use case – Energy savings in an office building
The device is insta lled to obtain energy s a vings in an office with an air condition. A Zig Bee relay is
installed to turn on the air condition when the occupanc y sensor detects movem e nts in the room. Th is
functionality c a n be obtained by using the standar d occu pa ncy sensor functionality – Standard ZCL
attributes.
Using the manufacture specific attributes in section 4.2.1.2 provide the user with an extra check
before the air condition is turned on.
The installer can configure the
ArmThreshold_MaxTemperature attribute to 25 degrees and when
movements are dete c ted in the room the r elay only turns on th e a ir condition when the te m pe r a ture is
above the MaxTemperature S ettin g ( 25 degrees).
The ArmThreshold_MinTemperature attribute can be u s ed in winter season where the air condition
shall warm up the room. The M in Temperature attribute is configu r ed to 20 degrees and when
movements are detected in the room and the temperature is below Min Temperature the air con d ition
is turned on heating the room.

5 MMI user guide
5.1 Push Button Menu:
Pushing the button on a device provides the user with several possibilities.
A single short push has a specific meaning for the given device, for this sensor a single sh ort push will
toggle the occupancy status (occupied/unoccupied.). Pushing the button for longer (push , hold for a
few seconds, and release) allows the user to set the device into a des ired m ode. A mode change
happens at 5 secon d interval. Below, these modes are illustra ted in a state chart.
When cycling through the menu modes, the state is indicated by a number of 100ms blinks on the
LED. As illustrated in the figu r e, the menu system allows for device spec if ic modes (e.g. Pair Devices
for Devices such as relays and occupancy sensors).
5.2 Action upon Push Button Release
The number of blinks associated with a given m ode entry is shown in th e b elow table along with the
associated action p er formed upon user button release. As indicated, if the user holds the button past
the Reset to Factory Fresh Settings n o a ction will result fr om the push button and the device stays in
the idle state.

5.3 Action on Power On
As a general rule, all end devices and routers that have not previously join ed a network (or have been
reset to factory default) will start up a nd search for a coordinator on the cha nnels enabled for that
device. In this mode, the LED w ill fla s h once every second.
Once a device has joined a network , the device will be in Identify Mode f or 15 minutes indicated by a
flash of the LED once every th r ee s ec onds.
If a device has joined a network and is powered down , it will attempt to rejoin this network u pon
power up. For the first 30 seconds hereafter, the device will be in Identify Mode.
5.4 Join Device on a Network
To allow a device to join a network, one either has to power up a d evice that has not previously joined
a network or push the button until the Re s et To Factory default mode is indicated – a nd subsequently
release the button . This will cause the de vice to reset to its factory default stat e and scan for a
suitable coordinator.
5.5 Toggle Identify Mode
To enter Identify Mode, the user may push and hold the button until the Identify Mod e m e nu is
indicated. If the device was not already in Identify Mode, the mode will be entered. Vice versa, if th e
device was already in Identify Mode, the mode will be disabled by the same action.

6 General network behaviour
6.1 Installation
When the device is virgin and powered for th e first time it will star t looking for a ZigB ee PAN
Coordinator or rou ter to join. The device will scan each ZigBee channel starting from 11 to 24. The
LED will flash once every second until it j oins a device.
#Scan mode - 1
Scan all 16
ZigBee channel
until join network
or 15 minutes
#Sleep mode
MCU is in sleep
mode (Radio off)
15 minutes
#Scan mode - 2
Scan all 16
ZigBee ch x 4 or
until join network
~ 2 minutes
#Sleep mode
MCU is in sleep
mode (Radio off)
15 minutes
#Scan mode - 2
Scan all 16
ZigBee ch x 4 or
until join network
~ 2 minutes
The device will start up using scan mode 1. To increase battery lifetime when the dev ic e is joining a
network for the first time a sca n mode 2 will be used after scan mode 1 ha s expired. Scan mode 1 it
will only be executed one time wh en the devise is powered.
In section 5 “MMI” it is explained how to pu t the device into a join or leave network mode.
Network settings a r e s tor ed in NV-memory are a f ter a power c ycle the device re-join the same
network.
If the device ha s to join a new PAN coordina tor the MMI menu supports a “ Reset To Factory Fresh
Settings” mode. This will erase all current network information.
6.2 Normal – Keep alive
The device is sending a “keep alive” mes s a ge to the PAN coordinator every 15 minute to verify that
the device is still connected to the networ k.
6.2.1 Network lost
If no “keep alive” responses are received 5 times in a row (Worst case 1h15m), the dev ic e s will start
scanning ever y ZigBee channel for the PAN coordinator and try to re-join it. Af ter scanning all 16
channels 4 times in a row the device will en ter sleep mode. The device w ill t oggle between each mode
until a re-join occu r.
When the device is in scan mode the LED will flash once e very second until it re-j oins the network.
According to the ZigBee spe c ification TX is NO T a llowed to be enabled all th e time and a TX silent
period has to be defined.
#Scan Mode

6.3 Low battery
The current battery voltage ca n be read from the power configuration cluster described in section
4.3.1. The attribu te “BatteryVoltage” is measuring the b a tte r y voltage, in un its of 100mV.
There is no led indica tion for low battery on the PIR sensor itself.
