I am looking for a wall mounted occupancy sensor to control the lights in the hallway in our home. There are three switches (two 3-way and one 4-way) that control these lights. I want to replace only one of the 3-way switches with a motion sensor to automatically turn the lights on and off. I also want the remaining switches to function as usual.
I have checked with Pass & Seymour and Leviton and they have nothing that will meet those demands. Lutron has an Occupancy Sensor switch (MS-OPS5MH) that I tried but after installation only the sensor functions. If either of the two remaining manual switches are operated the lights won't come on at all. After calling their tech support I am told I need to replace the two other manual switches with their "companion" (MA-AS) switches.
The sensor is not solid state and is rather loud when it changes state and I am not too sure I want to invest more in components that I won't be pleased with.
Does anybody know of any other manufacturers that I haven't mentioned that have what I'm looking for?
