Recently I purchased this occupancy sensing switch:
The instructions say that a ground is required. I suspected that my wiring might be lacking a ground but I didin't think it would be very hard to fish a wire to make the connection. So far I have had no luck getting my fish tool through my wall. I suspect that this part of my house is framed differently than other parts with ballon framing and wide open stud access from the basement. I still have some tricks up my sleve and may yet be able to get through the sill plate to make get a wire through.
I'm wondering, how important is the ground connection for this device? How does it work? Is it a safety issue alone or does it affect the fuction of the sensor somehow?
I HAVE NO GROUND OR WHITE WIRE WHAT DO I DO.
I'm having the same problem, but there are no white neutral wires to connect to. what do I need to do?
I bought several of these switches along with some timer switches. My house was built in the early 60's and all my switch boxes had the ground wire wrapped around the ground screw in the box. Even after hookng the switch up to this it still was not working propery. I had a neutral wire installed in some of these switch boxes, so instead I attached the ground to that and the switch worked as expected.
But, I think the reason why these switches aren't working properly with my ground connections is because I noticed there is no earth ground connected to my main panel.
I was having the same problem with this sensor switch. I had the thing hooked up correctly but the light was on and would not go off, and the switch would not respond to manual on/off.
After trying everything and even reading this thread, I called the company. I didn't want to tie ground into neutral without getting the OK from them.
The tech was very helpful and immediately knew what was wrong. He said the device didn't "like" the ground attachment and that I could just connect the green wire in with all the other white wires. He said to just cut off the bare wire on the device. I did this and it worked!
Lots of frustration but problem solved.
I was having the same problem. My lights were working, In my switch box, I had two black wires and two white wires that were tied together. I spoke with a licensed electrician who advised me to take the ground wire and bare wire from the Maestro sensor and tie them together with the two neutral white wires. PROBLEM SOLVED!

I'm having the same issue, and have tried several differnent occupancy switches within this brand. A regular switch works just fine, but the occupancy switch does not. I do not have a ground wire (though the conduit should act as a ground when properly done) and no neutral (as this sensor does not have one either). I only have a wire to the light and to the breaker.
So - what do I do? The instructions say that the ground MUST be properly connected for the switch to work, but I don't know why or how that is. Please advise!
anything is possible, its very easy to instal as you can see. Just return it to the store, get a new one and try it again.
Thanks for all the help guys. I tried installing the sensor last night and it wouldn't work. I reinstalled the regular switch and everthing worked fine.
Could it be that the sensing switch is bad?
