3-way motion sensors for stairway
 
Is it possible to use 2- 3way motion sensors to control one light in the stairway?
Just replace the 2 existing 3 way switches with motion senors.
Or....Can you only use 1 motion sensor with this scenario?
Thanks a bunch.

A 3 way switch is designed to swich an item, such as a light from 2 seperate locations. If you currently have 2 switches as such, then they are 3 way switches. They sell 3 way motion switches at lowes / home depot / menards for about $17 each. You would replace both 3 way switches with the 3 way motion switches and it would sense motion in both locations.

Thanks for your help. My concern is..I know with the old style dimmers, you could only put a 3 way dimmer at one end or the other. Will I have the same problem with with motion sensors?
Thanks

I actually used 2 single pole motion sensors on the stairway lights at my house. Either one will turn the lights on but both have to be off for the lights to be off. Its nice setup this way because I can disable one or the other motion sensors and still have the other turn the lights on. The sensor at the bottom of the stairs focuses out into the family room so the lights tend to come on frequently by just moving around in the family room. So the sensor at the bottom of the stairs is almost always in the "off" position, but with the added abilty to turn the lights to constant on without having to go to the top of the stairs to do so. Basically the two sensors are wired in parrallel.

I understood it to mean that you are looking to put a motion sensor at both locations, not a dimmer? Or are you just comparing this setup to that of a 3way dimmer?

There are different setups with the 3way dimmers due to the dimmer controal.

However with a motion sensor if you buy the 3-way motion controal, it can be turned on and off at either location, if we are just talking about a motion sensor setup, without dimmers, it is a simple setup. You are just purchasing a 3-way switch with a motion sensor attached to the switch, they work just like regular 3-way switches, but there is the motion controal on the switch.

You currently have 2 3-way switches that controal 1 or more lights correct? And you want those 2 switches to be motion sensor switches instead of regular light switches, is that correct?

Where in the store would you find these? I was looking and all I could find was the repacment sensore for outdoor lighting. I used one of these at the foot of my stairs but it is a little slow to activate, and once in awhile it wont come on at all.
The guy in Lowes didnt know a thing, but this is normal.

In lowes I am pretty sure they are right in the switch isle by the other switches. In Menards (in the midwest) they are next to the wire nuts / wire connectors in the switch isle, right across the isle from the switches. Anyway, in most stores they should be near the regular light switches, not the outdoor lighting. Or just buy it online:

I know they have the cooper brand at Menards and Lowes. I have the cooper one installed, and it works very well. Very fast at switching on.

I think I may have seen something like that. Thanks.

Darn I have my box mounted sidways, I wanted to tuck it up high to try to be out of sight.

They seem to work well at pretty close to a 180 degree range.. So that gives you a lot to work with.
