it’s not common connectivity or offline issue. It’s faulty LED controller. Well, maybe LEDs died too but I doubt it. It just stopped working.
Since I have 3 Auroras in my Living Room and 2 in my home office, I just took the AC adapter from another one and switched it with this one to eliminate at least one possibility. AC adapter works. Both AC adapters work, confirmed. So it has to be controller since it doesn’t even blink and cannot be reset.
My question is, especially for Yeelight staff, is it possible to order Yeelight Aurora strip, but without the AC because only controller with LEDs died.
By the way, this was that setup, unfortunately, lightatrip behind couch died.
