Notes

Pairing

Switch the thermostat off. Press and hold the temperature down button for +- 8 seconds to enable the pairing mode (display lights up and a WiFi-like icon is blinking). After successful interview turn the thermostat on again.

Climate

This climate device supports the following features: local_temperature, system_mode, fan_mode, current_heating_setpoint, preset, local_temperature_calibration.

  • current_heating_setpoint: Temperature setpoint. To control publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"current_heating_setpoint": VALUE} where VALUE is the °C between 5 and 35. Reading (/get) this attribute is not possible.
  • local_temperature: Current temperature measured on the device (in °C). Reading (/get) this attribute is not possible.
  • 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, cool, heat, fan_only. Reading (/get) this attribute is not possible.
  • preset: Mode of this device (similar to system_mode). To control publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"preset": VALUE} where VALUE is one of: auto, manual. Reading (/get) this attribute is not possible.
  • 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}.The minimal value is -3 and the maximum value is 3 with a step size of 1.

Deadzone temperature (numeric)

The delta between local_temperature and current_heating_setpoint to trigger activity. Value can be found in the published state on the deadzone_temperature 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 {"deadzone_temperature": NEW_VALUE}. The minimal value is 1 and the maximum value is 5. The unit of this value is °C. Besides the numeric values the following values are accepted: default.

Child lock (lock)

The current state of this lock is in the published state under the child_lock property (value is LOCK or UNLOCK). To control this lock publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"child_lock": "LOCK"} or {"child_lock": "UNLOCK"}. It's not possible to read (/get) this value.

Schedule (text)

Schedule will work with "auto" preset. In this mode, the device executes a preset week programming temperature time and temperature. Schedule can contains 12 segments. All 12 segments should be defined. It should be defined in the following format: "hh:mm/tt". Segments should be divided by space symbol. Example: "06:00/20 11:30/21 13:30/22 17:30/23 06:00/24 12:00/23 14:30/22 17:30/21 06:00/19 12:30/20 14:30/21 18:30/20". Value can be found in the published state on the schedule 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 {"schedule": NEW_VALUE}.

Linkquality (numeric)

Link quality (signal strength). Value can be found in the published state on the linkquality property. It's not possible to read (/get) or write (/set) this value. The minimal value is 0 and the maximum value is 255. The unit of this value is lqi.
