yeelight YDLT001: Cannot connect to the Yeelight Monitor Bar – Wifi is refusing the connection

I recently bought a Yeelight YDLT001, a nice looking lamp that should go on your monitor and lights your keyboard.

It is a smart device and need to be connected to your Wifi. The procedure is quite simple. Turn it on and off 5 times by disconnecting the USB-C cable. Then a WIFI network called somthing like Yeeligh-…. appears. The mobile phone shall connect to that network. Then use the Yeelight app (or the Xiaomi Home app) to connect. I had to replace the USB charger as it only has American sockets (I am in Germany). The Yeelight lights up. The backlight is always on, the fron light switches on and off.

Problem: The Yeelight WIFI appears. I am trying to connect from the iphone, the icon spins for a while, the it says “Cannot Connect”. Soon after the Yeelight Wifi disappears.

I tried:

  • iphone XS Max, iPad, Android, PC – always same effect
  • gave my Wifi 2.4 GhZ a different name (the Yeelight only likes 2.4 GHz)
  • millions way of reseting the device (unconnect USB-C, unconnect the power socket, disconnect the bar from thr bracket, …)
  • different USB charger – interesting enough on the more powerful charger (e.g. for Laptops) the device does not work. I had it finally on a charger delivering 5V/3A. Some reports in other fora said it needs 5V/2A/10W (hopefully “or more” 😉

Bottom line… it seems there is a bug that prevents to connect to the Wifi. Any help appreciated…
