Options

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 of 0 and with a maximum value of 3
humidity_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 of 0 and with a maximum value of 3

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 %.

Voltage (numeric)

Reported battery voltage in millivolts. Value can be found in the published state on the voltage property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"voltage": ""}. It's not possible to write (/set) this value. The unit of this value is mV.

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 %.

Report delay (numeric)

Adjust Report Delay. Setting the time in minutes, by default 5 minutes. Value can be found in the published state on the report_delay property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"report_delay": ""}. To write (/set) a value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"report_delay": NEW_VALUE}. The minimal value is 1 and the maximum value is 60. The unit of this value is min.

Enable temperature (binary)

Enable Temperature Control. Value can be found in the published state on the enable_temperature property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"enable_temperature": ""}. To write (/set) a value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"enable_temperature": NEW_VALUE}. If value equals ON enable temperature is ON, if OFF OFF.

High temperature (numeric)

Setting High Temperature Border. Value can be found in the published state on the high_temperature property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"high_temperature": ""}. To write (/set) a value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"high_temperature": NEW_VALUE}. The minimal value is -5 and the maximum value is 50. The unit of this value is °C.

Low temperature (numeric)

Setting Low Temperature Border. Value can be found in the published state on the low_temperature property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"low_temperature": ""}. To write (/set) a value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"low_temperature": NEW_VALUE}. The minimal value is -5 and the maximum value is 50. The unit of this value is °C.
