Exposes

Battery low (binary)

Indicates if the battery of this device is almost empty. Value can be found in the published state on the battery_low property. It's not possible to read (/get) or write (/set) this value. If value equals true battery low is ON, if false OFF.

Window detection (switch)

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

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.

Away mode (switch)

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

Heating (binary)

Device valve is open or closed (heating or not). Value can be found in the published state on the heating property. It's not possible to read (/get) or write (/set) this value. If value equals ON heating is ON, if OFF OFF.

Climate

This climate device supports the following features: current_heating_setpoint, local_temperature, system_mode, running_state, 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 30. 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, heat, auto. Reading (/get) this attribute is not possible.
• running_state: The current running state. Possible values are: idle, heat. 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 -6 and the maximum value is 6 with a step size of 1.

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.
