Notes

Adapter firmware

In order for this device to work (fully), at least the following firmware is required on your adapter:

Note that if you have already paired the device you will need to repair it after upgrading your adapter firmware.

Pairing

Press and hold the reset button on the device for +- 5 seconds (until the blue light starts blinking). After this the device will automatically join. If this doesn't work, try with a single short button press.

Note: When you fail to pair a device, try replacing the battery, this could solve the problem.

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.
