Great little product, good value. The sensor sends 2 rf signals, open / closed. The pin on the back also triggers a open rf signal when the device is removed from the surface that it is attached to. Works fine with the sonoff rf bridge. The distance between the sensor and the bridge is about 18 meters. I think that's about the limit for these. If i move them furter apart, the data of the rf signal is sometimes incorrect (different code).
