Turn your regular wall switch into a smart lighting trigger. Install Shelly Pro RGBWW PM in your breaker box to control your LED strips. Then, place a Shelly Decoupler near your existing smart device. The decoupler picks up the physical press and sends a command to Shelly Pro RGBWW PM.
This way, your old switch stays in place, but now it can change colors, adjust brightness, or trigger scenes. Clean, simple, and fully smart.
