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 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 with a maximum value of 3

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 %.

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 %.

Temperature units (enum)

The unit of the temperature displayed on the device screen. Note: wake up the device by pressing the button on the back before changing this value.. Value can be found in the published state on the temperature_units property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"temperature_units": ""}. To write (/set) a value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"temperature_units": NEW_VALUE}. The possible values are: celsius, fahrenheit.

Temperature calibration (numeric)

Offset to add/subtract to the reported temperature. Value can be found in the published state on the temperature_calibration property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"temperature_calibration": ""}. To write (/set) a value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"temperature_calibration": NEW_VALUE}. The minimal value is -50 and the maximum value is 50. The unit of this value is °C.

Humidity calibration (numeric)

Offset to add/subtract to the reported relative humidity. Value can be found in the published state on the humidity_calibration property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"humidity_calibration": ""}. To write (/set) a value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"humidity_calibration": NEW_VALUE}. The minimal value is -50 and the maximum value is 50. The unit of this value is %.
