LutronCaseta Smart Lighting Auto On and Off Motion Sensor, For Dimmers, Switches, and Fans Controls, No Wires Required, PD-OSENS-WH, White

This little sensor has been a game-changer. It automatically turns lights on when I walk in and off when I leave — no more fumbling for switches. Battery-powered and installs in minutes. Works seamlessly with my Caseta dimmers and hasn’t missed a beat.

90% off my house has the lutron caseta light switches. This motion design is put in my laundry room and it is fantastic! I dont have to try and turn the lights out while carrying a load of laundry! Will be buying many more of their products!

Wow. I just don't know what all these reviews are on about. Look, I get that if you expect something to work one way and it doesn't, you're going to be upset. And in that way the negative 1-3 star reviews here are valid. I'm here to tell you why I think this is a 5 star product.I'm a Homekit user. When I built my system up from the ashes of a prior ZWave setup, I made a big decision: anywhere I had a lamp, I'd use a Hue bulb. Anywhere I had a switch, I would use a Lutron Caseta switch. I don't have any need/desire for color in my lights, so this worked perfectly for me. My primary goal was to automate every single light in my house and do it as cheaply as possible.It's been 3 years now and there's one thing I'm certain of: Caseta products are the best home automation products ever made. I have NOT ONCE had a problem with my Caseta products, and the Hue stuff gives me constant headaches.The only motion sensors I have in my house are in my laundry room and hall closet. They're Hue sensors controlling Hue bulbs in the Hue app (Homekit is completely incapable of programming occupancy correctly - the biggest oversight in a platform full of problems). As I mentioned, I have frequent problems with all the Hue products, so I was THRILLED when Lutron announced their Caseta motion sensor. I think I literally jumped up and down, I was so excited. Imagine my disappointment when I checked out the reviews on Amazon and Reddit! Everyone hated it! I couldn't believe it!But, as I mentioned, I consider Caseta products to be the best ever, so I took a chance on the sensor...and I'm glad I did.Look, I'm using this thing in a room where I actually don't want to use a light switch. I'm using it in my garage workshop, and I've had it installed and operating for 2 weeks now. I can tell you that in my setup it has been nothing short of flawless.It takes less than a second for the lights to turn on when I enter the room. Less than if I'd used a switch. I have the sensor set to pick up minor movement and I have it set for a 5 minute timer. I have not ONCE had the lights turn out on me while I was in my garage. And that's pretty important when I'm using a freaking table saw. Even when I'm on the opposite side of the room standing very still in front of my wall-mounted computer, the sensor is able to pick up enough motion to keep the lights on. The entire time I've been writing this review, I've been standing 15-18 feet from the sensor with my back turned to it, and my slight movements have been enough for it to catch.On the flip side, I know that the five minute time-out is working perfectly. See, we have a fridge and freezer in our garage, so we regularly come out here to get something. I've had plenty of times where I've come back to the garage anywhere from 7-15 minutes later and the lights were off like they should be.Again, I'm not doubting the people who don't like this sensor. I'm assuming that if I walked into the room, the lights went on, then I walked out of the room and turned them off from a switch and then walked back in a minute later, the sensor wouldn't turn the lights on. I can see that complaint and I think it's reasonable. I just wanted to offer this counterpoint to argue that in my situation it's far and away the best possible option.SUMMARY: If you have a place in your home or business that you only want controlled by motion and not switches, this is the sensor for you.

I won’t cover all the points others have covered well in previous reviews but I’m going to put a few more things out there worth knowing about:1) Sensor coverage: The IR detector’s “view” is sort of a cone, but it is a downward tipping cone. Thus the view is extends straight out horizontally from the sensor window, extending downward from the horizontal plane.What’s that matter? It provides you with some tricks with the coverage. If you have pets, mount the sensor upside-down lower on the wall then recommended. e.g. 4’ instead of 6’-8’. People will still activate it, but dogs will not, as the view is horizontal, extending upward.On a staircase, I have one installed on the bottom wall, upside-down, so that it looks up the stairs.2) Speaking of which: Walking towards an IR sensor tends to work more poorly than when the motion is across the sensor view. Still, I’m impressed with how well it works when walking towards it.You can see details of the sensing area in Lutron’s spec sheet: https://www.lutron.com/TechnicalDocumentLibrary/3691125_ENG.pdf3) Outdoors? Official operating temp is 32 °F to 104 °F (0 °C to 40 °C). I’m not sure what will happen if it gets below freezing, but I’m going to try it. But if you can’t mount it in a covered area outside, you can always put it in a plastic bag, perhaps with an opening towards the bottom to reduce condensation. It does work through a bag, it does not work through glass.Oh, and bugs like to get inside such devices, and they can set them off crawling across the sensor. Close up those holes if mounting outside.4) Time On duration: No idea when, but the latest versions of this now have a 1 minute timeout setting. It’s not marked on the back of the unit: Just perform a normal duration setting procedure, pressing the timeout button until all 3 time LED’s start flashing. Then do a long press (couple of seconds) the 3 LED’s should glow steadily. There’s your 1 minute setting.5) Problem area: You do get more options if using this with the Lutron hub. Some. The one big frustration I have (as well as lots of others apparently) is that the IR sensor has no awareness that you’ve turned lights on or off manually. This would logically be possible with a hub involved, since it knows when lights are on or off and how they got into that state. Then the sensor won’t turn off the lights that you manually turned on. For now you should plan on either letting the motion sensor control the lights or users, but not both.The closest you can come to making the motion detector behave under manual control is if you switch your lights on and off from the on/off button on the detector itself. If you turn lights off with the button, it won’t turn them back on automatically again until all motion ceases. Think if you turn off the lights to watch a movie: they won’t automatically come on again until everyone has left.So in summary, it’s a nice sensor but as others have said, it would be even better if Lutron would deal with the problem areas. I know I’d buy more of them, but right now their limitations limit where I can use them. There may be a way around this with a different hub setup, but I’m not that far down that torturous path yet…

This is cool in a nerdy way... LOL I should have done it sooner. The cloths dryer blocks my laundry room switch, so the switch with sensor wouldn't have worked. The room is always extremely dark. Not having to worry about turning the lights on or off has been awesome. It's also a small room but I was able to place the sensor so it worked when either door is opened. FYIL 5mins is the shortest option to shut things off.Only issue: At first, I thought I got a bad sensor but then figured out that if I shut the light manually, the sensor doesn't turn on the next time. At this point, I assume replacing the other switch with a remote, would fix this but I'm not sure I want to pay $20 more for the remote to find out. It's not a huge deal either way... I simply don't touch the switch.

I have a fridge and freezer in my garage and I wanted the lights to come on whenever someone entered since we are often carrying food to put in them. I am using the setting to stay on for 5 minutes after the last motion is detected. Paired with a Lutron Caseta switch, works great.
