Notes
Pairing
To pair the device you first need to have it powered, attached to the valve and displaying the temperature.
If the device is showing FS or RD press the button on the top of the unit and it should now show ,,7
Once this stops flashing hold the top button for about 5 seconds at which point the unit should now show the temperature.
Keep turning the dial counter-clockwise unil the display shows OF and finally hold down the top button for 3 seconds.
You should now see a flashing signal icon and it will try and pair.
OTA updates
This device supports OTA updates, for more information see OTA updates.

Climate
This climate device supports the following features: occupied_heating_setpoint, local_temperature, local_temperature_calibration, system_mode, running_state.
occupied_heating_setpoint: Temperature setpoint. To control publish a message to topiczigbee2mqtt/FRIENDLY_NAME/setwith payload{"occupied_heating_setpoint": VALUE}whereVALUEis the °C between4and35. To read send a message tozigbee2mqtt/FRIENDLY_NAME/getwith payload{"occupied_heating_setpoint": ""}.local_temperature: Current temperature measured on the device (in °C). To read send a message tozigbee2mqtt/FRIENDLY_NAME/getwith payload{"local_temperature": ""}.system_mode: Mode of the thermostat. To control publish a message to topiczigbee2mqtt/FRIENDLY_NAME/setwith payload{"system_mode": VALUE}whereVALUEis one of:off,auto,heat. To read send a message tozigbee2mqtt/FRIENDLY_NAME/getwith payload{"system_mode": ""}.running_state: The current running state. Possible values are:idle,heat. To read send a message tozigbee2mqtt/FRIENDLY_NAME/getwith payload{"running_state": ""}.local_temperature_calibration: Offset to add/subtract to the local temperature. To control publish a message to topiczigbee2mqtt/FRIENDLY_NAME/setwith payload{"local_temperature_calibration": VALUE}.To read send a message tozigbee2mqtt/FRIENDLY_NAME/getwith payload{"local_temperature": ""}.The minimal value is-12.8and the maximum value is12.7with a step size of0.2.

Frost protection temperature (numeric)
Minimum temperature at which to automatically turn on the radiator, if system mode is off, to prevent pipes freezing.. Value can be found in the published state on the frost_protection_temperature property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"frost_protection_temperature": ""}. To write (/set) a value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"frost_protection_temperature": NEW_VALUE}. The minimal value is 4 and the maximum value is 35. The unit of this value is °C.
Idle steps (numeric)
Number of steps used for calibration (no-load steps). Value can be found in the published state on the idle_steps property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"idle_steps": ""}. It's not possible to write (/set) this value.
Closing steps (numeric)
Number of steps it takes to close the valve. Value can be found in the published state on the closing_steps property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"closing_steps": ""}. It's not possible to write (/set) this value.

Schedule (composite)
The preset heating schedule to use when the system mode is set to "auto" (indicated with ⏲ on the TRV). Up to 6 transitions can be defined per day, where a transition is expressed in the format 'HH:mm/temperature', each separated by a space. The first transition for each day must start at 00:00 and the valid temperature range is 4-35°C (in 0.5°C steps). The temperature will be set at the time of the first transition until the time of the next transition, e.g. '04:00/20 10:00/25' will result in the temperature being set to 20°C at 04:00 until 10:00, when it will change to 25°C.. Can be set by publishing to zigbee2mqtt/FRIENDLY_NAME/set with payload {"weekly_schedule": {"sunday": VALUE, "monday": VALUE, "tuesday": VALUE, "wednesday": VALUE, "thursday": VALUE, "friday": VALUE, "saturday": VALUE}}
