Hello @Solla-topee, you were right and I accidently found the problem. Apparently there was another switch that controlled the lights at a different spot in the garrage. Once I flipped that switch it...

Is that picture visible? Would another photo of the wiring help? The switch on the right, which is an HS200, works perfectly.

The ES20M switch on the left has power (as I can see it on the app), but it is not turning the lights on. Yes, I have tried replacing the light bulbs. It must be a wiring issue, correct? Can anyone...
