Notes
Pairing
Press and hold the reset button on the device for +- 5 seconds (until the blue light starts blinking). The reset button is the small button on the 'top' of the device. After this the device will automatically join. Please be close to the Zigbee gateway when pairing the device.
Troubleshooting: device stops sending messages/disconnects from network
Since Xiaomi devices do not fully comply to the Zigbee standard, it sometimes happens that they disconnect from the network. Most of the times this happens because of the following reasons:
- Device has a weak signal, you can see the signal quality in the published messages as
linkquality. A linkquality < 20 is considered weak. - Low battery voltage, this can even happen when the battery still appears full. Try a different battery.
- The device is connected through a router which cannot deal with Xiaomi devices. This is known to happen devices from: Centralite, General Electric, Iris, Ledvance, Legrand, OSRAM, Sylvania, SmartThings, Securifi. A possible solution is to connect the device directly to the central coordinator by pushing the reset button while being physically close to it.
