I have always had a problem with Yeelights, all of them. This simply must be a Yeelight firmware issue, I just can’t explain it. I have White bulb (2), Color bulb (2), strip (1) and Ceiling 650 (1). It happens with ALL of them. And as I have more devices, it is becoming a bigger and bigger problem to sort it out. But let me start from the begining:
If one member of the family forgets we have smartlights and turns off one of the lights (ANY!) by power switch, then I will NEVER get connectivity again until I turn off ALL the lights and ROUTER, and then turn on router and then lights.
If I reset router, then the light that was “offline” starts working, but 3 other lights stop. Impossible. And really unnerving! As I have more and more devices it is becoming tedious to turn them ALL off and on …
All devices have STATIC IP adresses on router. They are all on same Wifi 2.4ghz, same LAN segment etc.
When this happens… I am able to PING the device in question from ROUTER, but not from my PC. Sometimes this device even works from Yeelight APP (because it receives command from CLOUD!!) but my LAN communication is DEAD. Ping from my ultrabook which is on te same Wifi, doesn’t work! I reset the router - the lamp that wasn’t working starts working but 2 or 3 others stop.
It is driving me insane!
