None

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.

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"}. To read the current state of this lock publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"child_lock": ""}.

Climate #

This climate device supports the following features: current_heating_setpoint, local_temperature, system_mode, running_state, away_mode.

• 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. To read send a message to zigbee2mqtt/FRIENDLY_NAME/get with payload {"current_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, heat, auto. 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. To read send a message to zigbee2mqtt/FRIENDLY_NAME/get with payload {"running_state": ""}.
• away_mode: Away mode. To control publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"away_mode": "ON"} or {"away_mode": "OFF"}. To read send a message to zigbee2mqtt/FRIENDLY_NAME/get with payload {"away_mode": ""}.

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 minimimal value is 0 and the maximum value is 255. The unit of this value is lqi.
