Notes

Pairing

Plug the device in and wait for around 5mins, while it performs its self-tests. A successful self-test is indicated by couple of beeps and a steady green led. Now the device is ready for pairing. To initiate pairing quickly press the button three times in a row.

Sensitivity

The sensitivity can be changed by publishing to zigbee2mqtt/FRIENDLY_NAME/set{"sensitivity": "SENSITIVITY"} where SENSITIVITY is one of the following values: low, medium, high.

Self-test

A self-test can be trigged by publishing to zigbee2mqtt/FRIENDLY_NAME/set{"selftest": ""}. If the selftest is executed successfully you will hear the device beep in 30 seconds.

Options

How to use device type specific configuration

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