Notes

Pairing

Press the button on top of the device for at least 5 seconds but not more than 10 seconds (which will cancel the network configuration). The signal strength icon will begin to flash an keep on doing so until it stays solid (network config successful) or disappears (networkconfig failed).

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

Exposes

Temperature (numeric)

Measured temperature value. Value can be found in the published state on the temperature property. It's not possible to read (/get) or 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. It's not possible to read (/get) or write (/set) this value. The unit of this value is %.

Battery (numeric)

Remaining battery in %, can take up to 24 hours before reported. Value can be found in the published state on the battery property. It's not possible to read (/get) or write (/set) this value. The minimal value is 0 and the maximum value is 100. The unit of this value is %.

Voltage (numeric)

Voltage of the battery in millivolts. Value can be found in the published state on the voltage property. It's not possible to read (/get) or write (/set) this value. The unit of this value is mV.

Temperature unit (enum)

Current display unit. Value can be found in the published state on the temperature_unit property. 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 {"temperature_unit": NEW_VALUE}. The possible values are: celsius, fahrenheit.
