2.1 ZHOT101 - ZigBee Occupancy, Temperature & Light Sensor
The multi sensor enables you to detect movement and light as well as measuring temperature.
The sensor is battery powered and can be mounted in four different ways: flat on the wall, flat on the
ceiling, in the corner (using a 45° bracket), or standing (on a shelf, 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 “Configure Reporting” on change and on time is supported.
2.1.1 Occupancy
The occupancy sensor is PIR based, sensing moving objects up to 6 meters from the sensor. The off-
time is adjustable remotely via ZigBee. The end point is configured as Home Automation profile
„Occupancy Sensor“.
2.1.2 Light
The light sensor is a low-accuracy sensor reporting light level. The end point is configured as Home
Automation profile „Light Sensor“.
2.1.3 Temperature
The temperature sensor measures temperature with a resolution of 0.1°C. The end point is configured
as the Home Automation profile „Temperature Sensor“.

Use case – Energy savings in an office building
The device is installed to obtain energy savings in an office with an air condition. A ZigBee relay is
installed to turn on the air condition when the occupancy sensor detects movements in the room. This
functionality can be obtained by using the standard occupancy 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 detected in the room the relay only turns on the air condition when the temperature is
above the MaxTemperature Setting (25 degrees).
The ArmThreshold_MinTemperature attribute can be used in winter season where the air condition
shall warm up the room. The MinTemperature attribute is configured to 20 degrees and when
movements are detected in the room and the temperature is below MinTemperature the air condition
is turned on heating the room.

Use case – Energy savings in an office building
The device is installed to obtain energy savings in an office controlling the light. A ZigBee relay is
installed to turn on the light when the occupancy sensor detects movements in the room. This
functionality can be obtained by using the standard occupancy sensor Standard functionality - ZCL
attributes.
Using the manufacture specific attributes in section 4.2.1.2 provide the user with an extra check
before the air light is turned on.
The installer can configure the TargetLevel attribute to a user defined Lux level. When movements are
detected in the room and the Lux level is below the TargetLevel the relay turns on the light.

5MMI 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 short 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 desired mode. A mode change
happens at 5 second interval. Below, these modes are illustrated 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 figure, the menu system allows for device specific 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 mode entry is shown in the below table along with the
associated action performed upon user button release. As indicated, if the user holds the button past
the Reset to Factory Fresh Settings no action will result from 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 joined a network (or have been
reset to factory default) will start up and search for a coordinator on the channels enabled for that
device. In this mode, the LED will flash once every second.
Once a device has joined a network, the device will be in Identify Mode for 15 minutes indicated by a
flash of the LED once every three seconds.
If a device has joined a network and is powered down, it will attempt to rejoin this network upon
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 device that has not previously joined
a network or push the button until the Reset To Factory default mode is indicated – and subsequently
release the button. This will cause the device to reset to its factory default state 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 Mode menu is
indicated. If the device was not already in Identify Mode, the mode will be entered. Vice versa, if the
device was already in Identify Mode, the mode will be disabled by the same action.

15
6General network behaviour
6.1 Installation
When the device is virgin and powered for the first time it will start looking for a ZigBee PAN
Coordinator or router to join. The device will scan each ZigBee channel starting from 11 to 24. The
LED will flash once every second until it joins a device.
#Scan mode - 1
Scan all 16
ZigBee channel
until join network
or 15 minutes
#Sleep mode
MCU is in sleep

#Scan mode - 2
Scan all 16

~ 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 device is joining a
network for the first time a scan mode 2 will be used after scan mode 1 has expired. Scan mode 1 it
will only be executed one time when the devise is powered.
In section 5 “MMI” it is explained how to put the device into a join or leave network mode.
Network settings are stored in NV-memory are after a power cycle the device re-join the same
network.
If the device has to join a new PAN coordinator 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” message to the PAN coordinator every 15 minute to verify that
the device is still connected to the network.
6.2.1 Network lost
If no “keep alive” responses are received 5 times in a row (Worst case 1h15m), the devices will start
scanning every ZigBee channel for the PAN coordinator and try to re-join it. After scanning all 16
channels 4 times in a row the device will enter sleep mode. The device will toggle between each mode
until a re-join occur.
When the device is in scan mode the LED will flash once every second until it re-joins the network.
According to the ZigBee specification TX is NOT allowed to be enabled all the time and a TX silent
period has to be defined.
#Scan Mode
Scan all 16 ZigBee channel x 4

6.3 Low battery
The current battery voltage can be read from the power configuration cluster described in section
4.3.1. The attribute “BatteryVoltage” is measuring the battery voltage, in units of 100mV.
There is no led indication for low battery on the PIR sensor itself.
