4.0 out of 5 stars Great unit but there's a trick to setting it up
Reviewed in the United States on December 17, 2022
Style: Line Voltage | Motion Sensor OnlySize: 12 Foot RadiusVerified Purchase
This is a good device from a legitimate electrical company from what I can tell.

Install is easy. No polarity so it's painless.

The programming is not the easiest thing in the world but it's not hard, you just have to understand the blinking light concept and pay attention to the pauses and blinks. It's a little confusing at first.

The only thing I needed to program was the delay even though you can program a lot with this. It took me 3 days to program the delay. I googled. I YouTubed. Could not get my setting to stick. It was driving me nuts. I finally resigned myself to look at the directions for the 20th time and looked at the other settings. Voila.

Here is the trick (the manufacturer should add this to the instructions as STEP ONE):

In order for the delay to work, the first thing you MUST DO is change the minimum time on setting. Mine was set to 15 minutes by default. Who knew?

So.. BEFORE YOU PROGRAM THE DELAY, go into the minimum on mode and change it to something LESS than the delay you want to use. I made mine ZERO because my delay is 30 seconds.

After I changed the Minimum time on setting, my delay worked perfectly. No way a 30 second delay is going to work if the minimum time on is 15 minutes!

Also, this is a 360 degree sensor. I wanted to limit the sensor so when I was in the bathroom, the sensor (in the master closet without a door) wouldn't activate and would only turn on as I walked into the closet.

Simple solution: put a little electrical tape over the sensor as necessary to shield the motion. Works great. Use white electrical tape for 2 extra style points.

After I figured out the position of the tape and knew it worked, I designed and 3D printed a little hood that I glued on. Looks factory and works perfectly every time I step in the same spot. I almost think they should include something like this in the box as it's kind of necessary in many instances.

5.0 out of 5 stars Works great in my 2-car garage
Reviewed in the United States on August 16, 2020
Style: Line Voltage | Motion Sensor OnlySize: 28 Foot RadiusVerified Purchase
This item is not cheap and has capabilities I'll never use but I bought it because the performance claims sounded good and the reviews were good. My 2-car garage is 25' wide x 20' deep x 9' high with the interior entrance to the house up a 4' set of steps in a section with a higher overhead. I mounted it to a rafter in the center of the garage. I wired it in parallel with a light switch. Using the advertised coverage pattern I understood why opening the interior door didn't trigger the motion sensor, so I removed one mounting screw and loosened the other so to tilt the sensor up in its view of the interior door and down in its view of the garage doors. Works great.
