How to use device type specific configuration

Exposes #

Local_temperature (numeric) #

Current temperature measured on the device. Value can be found in the published state on the local_temperature property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"local_temperature": ""}. It’s not possible to write (/set) this value. The unit of this value is °C.

Lock #

The current state of this lock is in the published state under the keypad_lockout property (value is 1 or 0). To control this lock publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"keypad_lockout": "1"} or {"keypad_lockout": "0"}. To read the current state of this lock publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"keypad_lockout": ""}.

Climate #

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

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.
