Review on Ecoeler 3-Way Motion Sensor Light Switch - Neutral Wire Required - UL Listed And FCC Approved - Indoor Motion Activated Switch - Pack Of 1 by Robert Maysey

I bought one of these to use with a Lutron sensor in a 3 way system. The wiring for this has a neutral and the Lutron did not so the wiring wasn't straight forward. Bought a second so I could detect movement coming into the stairway from the top and the bottom. For 3way you essentially wire everything in parallel and cap the blue. The one at the base of my stairs was still detecting movement in my room even at the lowest sensitivity. I ended up blocking half the sensor with tape to prevent this.Overall they work well together. Wish there was an alley mode or a way to cover part of the lens for a narrow sensing area. Also the relays are louder when the light turns on than I'd like.
