OTA updates

This device supports OTA updates, for more information see OTA updates.

Options

How to use device type specific configuration

  • thermostat_unit: Controls the temperature unit of the thermostat (default celsius). The value must be one of celsius, fahrenheit

Exposes

Child lock (binary)

Enables/disables physical input on the device. Value can be found in the published state on the child_lock property. It's not possible to read (/get) this value. 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.

Climate

This climate device supports the following features: local_temperature, pi_heating_demand, local_temperature_calibration, occupied_heating_setpoint, unoccupied_heating_setpoint, system_mode.

  • pi_heating_demand: Position of the valve (= demanded heat) where 0% is fully closed and 100% is fully open. To control publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"pi_heating_demand": VALUE} where VALUE is the % between 0 and 100. To read send a message to zigbee2mqtt/FRIENDLY_NAME/get with payload {"pi_heating_demand": ""}.
  • 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 7.5 and 28.5. To read send a message to zigbee2mqtt/FRIENDLY_NAME/get with payload {"occupied_heating_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, auto, heat. To read send a message to zigbee2mqtt/FRIENDLY_NAME/get with payload {"system_mode": ""}.
  • 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 -12.8 and the maximum value is 12.7 with a step size of 0.1.

Mirror display (binary)

Mirror display of the thermostat. Useful when it is mounted in a way where the display is presented upside down.. Value can be found in the published state on the mirror_display property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"mirror_display": ""}. To write (/set) a value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"mirror_display": NEW_VALUE}. If value equals ON mirror display is ON, if OFF OFF.

Battery (numeric)

Remaining battery in %. Value can be found in the published state on the battery property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"battery": ""}. It's not possible to write (/set) this value. The minimal value is 0 and the maximum value is 100. The unit of this value is %.

Trv mode (enum)

Select between direct control of the TRV via the valve_position_mode or automatic control of the TRV based on the current_heating_setpoint. When switched to manual mode the display shows a value from 0 (valve closed) to 100 (valve fully open) and the buttons on the device are disabled.. Value can be found in the published state on the trv_mode property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"trv_mode": ""}. To write (/set) a value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"trv_mode": NEW_VALUE}. The possible values are: auto, valve_position_mode, manual.

Valve position (numeric)

Directly control the radiator valve when trv_mode is set to valve_position_mode.The values range from 0 (valve closed) to 100 (valve fully open) in %.. Value can be found in the published state on the valve_position property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"valve_position": ""}. To write (/set) a value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"valve_position": NEW_VALUE}. The minimal value is 0 and the maximum value is 100. The unit of this value is %.
