I'm using Google Home Mini in France. I have an Mi/Yeelight account, everithing works perfectly with one RGB bulb.
But, when i try to connect my Yeelight account on Home, the screen gets back to "add a device" screen.
DNS change on modem -> no change
Firewall rules edited on modem -> no change
GOOD PARAMETERS FOR GOOGLE HOME -
Yeelight app set on "Singapore"
RGB bulb works with Yeelight Android app
RGB bulb works with IFTT on Android and Google Home Mini
RGB bubl can't be connected to Google Home app (any device appears after login on yeelight account on Google Home app)
