Xiaomi: Lost devices or functional issues
The below may resolve Xiaomi devices/sensors getting lost after deconz restart OR sensors not working properly due to an incomplete node descriptor.
Also, you will most likely need 2 persons for that depending on the sensor's location: one continuously pushing the button on the device, the other one doing the required steps in deconz GUI.
- Open the Phoscon App → Menu → Sensors;
- Click "Add new Sensor" → Other;
- Press the button in the small pin hole like 10 seconds until the sensor LED blinks blue;
- Open / close the sensor a few times, the sensor should now be added and the node shown in deCONZ GUI.
Nothing new yet as some data is missing.
- Right click on the node and select Read node descriptor;
- Quickly after that press the pin hole button on the sensor;
- Right click on the node and select Read simple descriptors;
- Quickly after that press the pin hole button on the sensor again.
When everything is queried it should look like in the last screenshot and the sensor node survives a deCONZ reboot. Note you can repeat the last steps if it doesn't work the first time.
