You may have bought the Xiaomi Dling/Ding ling (丁玲）smart doorbell but having trouble pairing with the bell/chime receiver.
It's actually really simple to pair it.
- First, you press once on the Bell Receiver middle button and you will hear one beep sound
- Next, press on the door bell (around 5 secs) until it says "已发送配对请求，请查看手机推送" (It translates to, Already sent out pairing request, please check your phone push notification).
- Check your mobile phone for the notification and authorize the pairing.
And the bell/chime receiver will be paired
However, sometimes you may receive an error message "Device is offline and cannot be authorized". This could be caused by the bell device and your current phone wifi connection is not on the same Wifi SSID. The solution to this is simple, just connect to the same Wifi netowork/SSID and try the steps again!
