Yeelight not connecting

I own 6 yeelight bulbs, i think s1, and 2 of them went offline last month or so. I have tried:

  • resetting the bulbs
  • changing the settings to mainland China in the yeelight app
  • logging out and back in the app
  • using xiaomi home
  • using 4g hotspot(didn’t work)

Note: I can’t access my wifi settings.

Hello, according to the previous network environment, you can reset the lamps and add them. Did you encounter any problems when adding them

Heyy there, I have tried that solution many times, but it either says network time out or just cant add them.

Hello, you can change the network to test, or there is a problem with the communication module
