How to use device type specific configuration
temperature_calibration: Calibrates the temperature value (absolute offset), takes into effect on next report of device. The value must be a number.temperature_precision: Number of digits after decimal point for temperature, takes into effect on next report of device. This option can only decrease the precision, not increase it. The value must be a number with a minimum value of0and with a maximum value of3humidity_calibration: Calibrates the humidity value (absolute offset), takes into effect on next report of device. The value must be a number.humidity_precision: Number of digits after decimal point for humidity, takes into effect on next report of device. This option can only decrease the precision, not increase it. The value must be a number with a minimum value of0and with a maximum value of3co2_calibration: Calibrates the co2 value (absolute offset), takes into effect on next report of device. The value must be a number.identify_timeout: Sets the duration of the identification procedure in seconds (i.e., how long the device would flash).The value ranges from 1 to 30 seconds (default: 3). The value must be a number with a minimum value of1and with a maximum value of30
Exposes
Temperature (numeric)
Measured temperature value. Value can be found in the published state on the temperature property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"temperature": ""}. It's not possible to write (/set) this value. The unit of this value is °C.
Humidity (numeric)
Measured relative humidity. Value can be found in the published state on the humidity property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"humidity": ""}. It's not possible to write (/set) this value. The unit of this value is %.
CO2 (numeric)
Measured value. Value can be found in the published state on the co2 property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"co2": ""}. It's not possible to write (/set) this value. The unit of this value is ppm.
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 %.
Identify (enum)
Initiate device identification. Value will not be published in the state. 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 {"identify": NEW_VALUE}. The possible values are: identify.
