I have a couple of BRUH LED setups running and they both power off rat random intervals.HA shows them as OFF and i can turn back on. Sometime they can run for hours, other times 30 minutes before they power themselves off. Any idea why please as nothing in the HA logs? Any debugging I can turn on to see more info please?
I just noticed in the logbook the switch off is recorded…
You could add a push to mqtt when it’s starting. Or with serial out.
An full strength wifi signal on a cell-phone for example is of no relevance here. I had problem where reception on smartphone was perfect.
Appart from wifi, a bad power supply might also be the cause.
What are you using? Some wemos d1 mini? Or some other esp board?
To be sure about the wifi you could try to move one lamp temporarily at 1 or 2 meters from your access point.
