Pairing
Long press reset button for 5s until the LED indicator flashes three times, which means the device has entered pairing mode
Sometimes the battery is not mounted firmly which prevents the device from pairing properly. Adding a washer between the battery holder and the battery or increasing the pressure on the holder fixes this.
Known Issues
There are connectivity issues with this device. They disconnect form the network after several hours and don’t connect again. When that happens you need to pair them again.
Battery replacement
In theory these devices should automatically re-join the network after battery replacement. I have observed that (at least when working with deconz) they dometimes do not. When they do it is immediately obvious - the status in Phoscon (deconz) is immediately updated, with the device showing open or closed rather than unavailable. When they don’t, nothing happens, with the device continuing to show as unavailable. To re-pair them it isn’t necessary to delete them and create a new device. Instead:
- Replace the battery
- In Phoscon go to Devices > Sensors > Add new sensor
- Click Other to start it searching for new devices
- Put into pairing mode as described above Fairly quickly the device will be re-connected as it originally was. You won’t need to re-create it in Deconz or Home Assistant. Hopefully other bluetooth stacks behave the same.
