I went back through the settings on my failed switch because I thought that I could get it going again by turning on relay click. That was not the case, but in the process, I found that smart bulb mode was turned on. This is a pantry light with a dumb LED bulb, and I don’t have smart bulbs in the house (tried them, not reliable). I turned smart bulb mode off and the switch is working normally.
This is the second time I have had smart bulb mode get turned on, and I think it is happening with the config button. I started another thread about this: Disable the config button
The only time I would use the config button is to factory reset. It is easy to accidentally hit the config button, especially where switches are on the right side of you. Happens all of the time to me and it is very annoying because one you accidentally hit it you have to tap the switch 3 times to get the light to turn on. My family does this often as well and think the switch is broken.
