Recently one of my S20 has been giving me an issue that scared my into taking it out of service.
Randomly shut off then on again and now it won't shut off. It's now a Sonon, lol!
I thought it was a breaker trip but it wasn't and no matter how I try to shut it off (app or manually) it stays powered on. Guess the relay bit the dust as the LEDs agree with the reported state of operation regardless of actual always on state.
So leds are not reporting actual state (no feedback from relay) and only what's been triggered.
