HomeSeer PS100 Z-Wave Presence Sensor, 800 Series Long Range Z-Wave Technology

I put one inside a wooden picture frame, behind a home store "painting" on the wall and it works flawlessly. These are the best new home automation devices to come onto the market in years.

The presence sensor is flawless. It is a level up from a standard motion sensor. I use it in my office, and my wife is very happy that the lights don't turn off when she is working at her computer and not moving much. I've purchased four to replace the PIR sensors in some rooms.

Outstanding product, wish it had been available years ago.
