Scarlett R. ★★★★★

The Bluetooth range is solid enough that I can leave my phone in the hallway and still get instant motion alerts from the bedroom sensor. Paired it with my existing Busch-Jaeger switches and the adapter clicked right into place without any extra wiring headaches.

Leo I. ★★★★★

Setup took maybe ten minutes with the Busch-Jaeger adapter snapping right into place, and the Bluetooth range through two walls has been solid. The motion sensor picks up even slow movement from across the room, which is exactly what I needed for automating the hallway light.

Julian ★★★★★

The motion detection is impressively quick—lights respond the moment I walk in, no noticeable delay. Paired with my Busch-Jaeger setup, it feels like a native part of the system rather than an add-on. Just wish the Bluetooth range were a bit longer for larger rooms.
