Notes

Pairing

To pair this device you have to install the device via its installation code which you can get by scanning the QR-code sticker on the physical device with your smartphone. Then get the device into pairing mode. In zigbee2mqtt navigate to "Settings" --> "Tools" and click on "Add install code". Paste the code you got from the QR-code and confirm by clicking "OK" which will get zigbee2mqtt into pairing mode automatically. Wait for your device to be joined.

Factory resetting

To factory reset the device remove one of the batteries. While pressing and holding the device's main button, insert the battery back. As soon as the device's LED is starting to blink orange, release the device's main button and press and hold it again until the device's LED is lighting up green. You will know that the device is being set back to factory defaults successfully when an acustic signal is being thrown by the device. The device will reboot, which can take up to a minute.

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

• voc_calibration: Calibrates the voc value (absolute offset), takes into effect on next report of device. The value must be a number.

• co2_calibration: Calibrates the co2 value (absolute offset), takes into effect on next report of device. The value must be a number.

• illuminance_lux_calibration: Calibrates the illuminance_lux value (percentual offset), takes into effect on next report of device. The value must be a number.
