Question Occupancy Sensing Switch

Hello,

I was hoping to get some feedback or comments on a change I am considering making to a garage light. Currently I have a 2 bulb T8 shop light fixture that is controlled by two switches. One in the actual garage and one in the basement. My plan was to change ONLY the garage one to an Occupancy Sensing Switch that will come on as we enter the garage. Making it much more convenient than reaching for the switch with hands full. At the same time leaving the "standard switch" in the basement. So the light can be switched on/off as needed.

My first question is this possible with a 3 pole switch setup? My thought is it MIGHT not work. Due to the fact that once it's been switched off (from the basement) the Occupancy Sensing Switch will have no ability to turn the fixture on. Second if this is possible are there any limitations to doing this because of the T8 florescent fixture.

Thanks for any thoughts or suggestions.

It should be, with the right controls.

Oh yes it will. You can turn the light off from the basement and a proper 3-way motion sensor will turn it back on as soon as the cat walks through the garage. It'll time out and turn itself off after awhile, of course, so I doubt if you'll get much use out of the switch in the basement.

Second if this is possible are there any limitations to doing this because of the T8 florescent fixture.
Good question. Look closely at the specs for any device you consider. The problem is more often associated with photocell controls than with motion sensors though.

There aren't too many motion sensors that are three way capable and can operate fluorescent but I believe the Leviton part in the link below should work. A compatible switch for remote three way operation is required. It's called the IPV0R sensor remote. Also mentioned in the link.

Leviton IPS15-1LZ 1800-Watt Incandescent, 600-Watt LED/CFL Occupancy Sensor (Auto ON/Auto OFF), Single Pole or 3-Way - Amazon
