Pairing

To pair this device you have to install the device via its installation code. The installation code can be obtained by scanning the QR-code on the back of the cover with your smartphone. Then get the device into pairing mode. In zigbee2mqtt navigate to "Settings" --> "Tools" and click on "Add install code". Paste the code you got from the QR-code and confirm by clicking "OK" which will get zigbee2mqtt into pairing mode automatically. Wait for your device to be joined.

Options

How to use device type specific configuration

humidity_calibration: Calibrates the humidity value (absolute offset), takes into effect on next report of device. The value must be a number.
humidity_precision: Number of digits after decimal point for humidity, takes into effect on next report of device. This option can only decrease the precision, not increase it. The value must be a number with a minimum value of 0 and with a with a maximum value of 3
thermostat_unit: Controls the temperature unit of the thermostat (default celsius). The value must be one of celsius, fahrenheit

Climate

This climate device supports the following features: local_temperature, occupied_heating_setpoint, occupied_cooling_setpoint, local_temperature_calibration, system_mode, running_state.

occupied_heating_setpoint: Temperature setpoint. To control publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"occupied_heating_setpoint": VALUE} where VALUE is the °C between 4.5 and 30. To read send a message to zigbee2mqtt/FRIENDLY_NAME/get with payload {"occupied_heating_setpoint": ""}.
occupied_cooling_setpoint: Temperature setpoint. To control publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"occupied_cooling_setpoint": VALUE} where VALUE is the °C between 4.5 and 30. To read send a message to zigbee2mqtt/FRIENDLY_NAME/get with payload {"occupied_cooling_setpoint": ""}.
local_temperature: Current temperature measured on the device (in °C). To read send a message to zigbee2mqtt/FRIENDLY_NAME/get with payload {"local_temperature": ""}.
system_mode: Mode of this device. To control publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"system_mode": VALUE} where VALUE is one of: off, heat, cool. To read send a message to zigbee2mqtt/FRIENDLY_NAME/get with payload {"system_mode": ""}.
running_state: The current running state. Possible values are: idle, heat, cool. To read send a message to zigbee2mqtt/FRIENDLY_NAME/get with payload {"running_state": ""}.
local_temperature_calibration: Offset to add/subtract to the local temperature. To control publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"local_temperature_calibration": VALUE}.To read send a message to zigbee2mqtt/FRIENDLY_NAME/get with payload {"local_temperature": ""}.The minimal value is -5 and the maximum value is 5 with a step size of 0.1.

Humidity (numeric)

To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"window_detection": ""}. To write (/set) a value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"window_detection": NEW_VALUE}. If value equals ON window detection is ON, if OFF OFF.

Boost heating (binary)

Activate boost heating (5 min. on TRV). Value can be found in the published state on the boost_heating property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"boost_heating": ""}. To write (/set) a value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"boost_heating": NEW_VALUE}. If value equals ON boost heating is ON, if OFF OFF.

Child lock (binary)

Enables/disables physical input on the device. Value can be found in the published state on the child_lock property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"child_lock": ""}. To write (/set) a value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"child_lock": NEW_VALUE}. If value equals LOCK child lock is ON, if UNLOCK OFF.
