Recessed Door Sensor is a simple idea. It tells you and your Z-Wave network if a door is open or closed. Installing Recessed Door Sensor is easy. Adding it to your homes network takes no more than activating its battery and syncing it with your Z-Wave system. Making the whole thing invisible means little more than a slight drill hole hidden away on the top of your door. Its the sort of installation that takes no more than 10 minutes but provides years worth of benefits.
Batteries: 1 x 3v CR2 (supplied)
