Makes life easy, but has a few issues
Update, Oct 2024:The motion sensor is still very sensitive but it turned out the problem with the timer was my error. I’d set up a rule to turn the light off after 10 minutes but elsewhere in the app I’d set it to turn off if it didn’t detect motion for 1 minute. So after 1 minute of me being out of sight of the motion detector it turned itself off, as I’d instructed it to. So a good slap of my own forehead here, a very loud “D’oh!” in my best Homer Simpson voice, and I’m restoring the fifth star to the product.Update, Aug 2024:The motion sensor is very sensitive. I’ve got mine set to the lowest setting and it activates when I’m 10 feet away in an adjacent room. It would be nice to be able to set it to be much less sensitive, so it activates if I walk past it but not if I walk somewhere in the general vicinity. It’s as if the angle of view is fairly narrow, so that if I’m walking along the wall where it’s located it doesn’t respond until I walk right in front of it, but if I’m in the next room it will activate with me a clear 10 feet or more away. That’s tedious, because it means if I stand at my bench to mend something the pantry light keeps turning on.There’s also an issue that might be with the switch and might be with the Kasa app (I suspect the app, but the two go together). Because I’m prone to forget to turn off the pantry light (and sometimes it’s hard to turn it off if I’ve got both hands full) I set up a rule in the software that activates when the light is turned on, and turns it off 10 minutes later. 10 minutes is plenty of time to find what I need in the pantry and leave, except that it actually turns off after more like 2-3 minutes.These aren’t major issues but are irritating enough to knock off a star. There’s not much point having time-based options if what happens bears so little resemblance to what I programmed, and it’s been known for years that motion sensors that activate whenever anything happens remotely near them are of limited use.I still plan to install the other one in the attic, I’ll just leave it to a standard rule to turn it off.Original review:I fitted a motion sensor switch to the room in my basement where I keep the chest freezer. When I take stuff down to the chest freezer I need to figure how to turn the light on, which can be tricky when I’ve got both hands full with stuff to go in the chest freezer. I can flick a switch with an elbow but it’s a bit of a drag. And sometimes when I leave the room I forget to turn the light off, and find it still turned on a couple of days later when I’m next down there.A switch like this solves all these problems at once. The motion sensor means all I have to do is walk past it and the lights come on. And being a smart switch it means I can set up a rule that turns the light off again after 15 minutes. As a fallback I have a “scene” set up in the Kasa app that turns all the automated lights off at midnight regardless, so if the rule doesn’t work as expected it will still shut off at midnight.Be aware these switches are quite deep. I had to replace the back box to fit it, because the previous switch I had was the smallest switch available. The metal back box that was in place was deep enough to hold the Kasa switch but didn’t have enough free space to handle the cables in and out and the wire nuts behind the switch. But now I have a deeper back box and a switch that works very nicely.Installing the switch is about as easy as it gets. It has four wire tails – a white one to connect to neutral, a green one to connect to earth, and two black ones to connect to line/load. All you have to do is figure which wire is which, use the supplied wire nuts to join the wires together, and configure the switch. If you can’t figure out electrics as simple as this, pay an electrician to do it for you.The default level of sensitivity had the light triggering if I went anywhere near it, so I turned it to the lowest sensitivity (this is done in the Kasa app) and now I have to walk right up to it before it activates. That’s perfect for my needs, I don’t want it turning on unless I actually go into the room where it is installed.As a smart switch it can be configured to activate only when ambient light is low, it has different levels of sensitivity for the motion sensor, and it can be controlled remotely and programmed to turn on and off at particular times. That sort of thing has obvious uses if you’re going to be away for a few days, you can set up timers so it’s not so obvious you’re not home. You can also do all sorts of weird and wonderful things if you’re so inclined, so if it takes your fancy you can set it up so that if you walk into the room where the switch is installed it will some totally unrelated device on or off. Why you’d want to turn the attic power strip off when you walk into a room in the basement is another matter, but you can if you want to.I have two of these, and I’m thinking a motion switch to turn the attic light on might be a handy thing to have, for similar reasons.

Yes! Been wanting this for a while!
This switch was one I’ve been waiting for. I have a variety of of brands of smart switches and other devices in my house. I have some from some major brand sold in home stores. So far The Kasa – TPLink switches have been not only the most reliable, but by far have been the most affordable for a quality switch. This brand has become my favorite. This switch had a neutral wire. It installed very easily. It came with paper stickers to flag wires, if you are into that. I tried doing setup from memory. It almost worked. I was stuck in a state where I couldn’t enter my house wifi credentials. So I deleted it from the Kasa app, and followed the instructions. It worked great. I set the minimum brightness for 1% and added it to my Alexa list, and to my kitchen group. I named it’s type as a light, to keep it simpler for Alexa. It works perfectly! I highly recommend. Now I can ask Alexa to turn the light on if it times out. I have 12 LED’s in my kitchen, and this switch controls only 4 of them. This way I have some light when I enter, and I can command the rest of the lights on if I want. Very happy. Very fair price.

Very nice looking and functional! but…
I bought and installed this, and so far they are working very good, connecting with the app was easy and works fine with Alexa… WILL NEED TO HAVE A NEUTRO!!! And no, it’s not the white load wire… You will need 4 cables to make this work… Hot, Neutral, Ground, and a Load wire for the light, so check your cables before buying; otherwise, you’ll have to do some extra work.

Works great but needs either HomeKit or Matter support
We love how we can turn out the lights over our kitchen island without having to get up from our couch. We love the way the lights can be dimmed either from an app or from the switch itself. We love how there’s a small white ring-shaped LED on the switch that you can see when the lights are off. It disappears when you turn the lights on. It is a very dim, unobtrusive ring of light, but is plenty bright enough when the room is dark. The same light ring comes on in orange or green when you program the switch in the Kasa app. They were fairly easy to wire-up, install, and program. I’m a fairly competent DIYer, but I have a brother-in-law who’s an electrician, so that definitely helped my confidence level.The system isn’t perfect, though. It works with Alexa and some of the other “smart home” apps, but not Apple’s HomeKit. Granted, way more people use Alexa and other products, so there isn’t a real need for TP-Link to bring out the 3-way switch in the Apple format. However, there is a new standard “communication protocol” (not sure of that term) that has been rolling out called Matter. If you don’t know what I’m talking about, Matter is a communication “standard” that all the MAJOR manufacturers of smart devices have adopted to allow these devices to talk to each other. The idea is, you can have an Apple TV 4K and use it to operate smart items that were originally only set up to use Alexa, or one of the other systems. I may not have all the “jargon” right, but I think I am communicating the general idea of Matter correctly.Kasa have just come out with new single-pole switches that use the Matter standard. I bought and installed two of them on some of our other kitchen lights. They were as easy to program as the 3-way switches I’m currently reviewing. Now I can use the Kasa app OR the Apple HomeKit app (and my friend Siri) to turn those lights on and off. I’m hoping TP-Link will come up with a way to convert these 3-way switches in the future, but I don’t know if it’s possible. I asked, but TP-Link have no comment about their plans (which makes me think they can’t or won’t be doing so).So 2 thumbs-up on the 3-way Kasa light switches. The reason I didn’t give a 5-star rating is because of the need for a neutral wire in the switch box and how big the bodies of the switches themselves are. I had to dig out the bundle of stiff, 27 year old, 12-gauge, solid wires, separate them, and reconnect the bundle of neutral wires with the neutral wire from the switch, using the biggest wire nut I’ve EVER seen. Then I had to do the same thing with the bundle of ground wires that were jammed in the back of the box too. The extra wires and bigger wire nuts made it very hard to get the switches into the box. Putting all that aside, I’m impressed by the switches and glad I did it.

We had an electrician install this as we are not handy. However I did the setting up after install and it was fairly easy to do. Able to sync with alexa flawlessly.The only caveat is whenever you change you wifi password, you will have to re install and update wifi password to each light switch.

Needed someone to help me install this, but after that, it worked wonderfully. It has never malfunctioned, and does whatever I program it to do. The app is also moderately intuitive and easy to use. We have a bathroom where the light switch is a few feet away from the door and it was inconvenient to go in at night and try to find the switch. This motion-sensor light solved those problems completely.

I have like 10 kasa switches now. They are much better and cheaper than smart bulbs because if someone turns the. Off authentic switch the voice and smart functions still work unlike bulbs. And more cost effective

Had to replace a Lutron occupancy sensor switch after a few years as it started misbehaving. Bought a 15A replacement at a local store but my LED lighting load is only 240W so I looked around online. To my surprise, the Kasa product costs much less and is Smart.However, the description on Amazon does not explicitly state what LED load it can handle; it only states 600W incandescent and 1/6HP motor. So I gambled it would be OK and it seems to be, but not confirmed by anything on the box or in the enclosed Quick Start Guide. If you get filtered onto the Canadian website for TP-Link/Kasa, the product is not even listed. The Lutron MS-OPS5M is likewise rated at 600W incandescent and 360W LED so I think the Kasa shoudl be similarly rated for LED.Once installed and set up with the Kasa Smart app (including an update to the firmware), I learned that my switch is Hardware Version 1.0. There is a later version 1.8 reported on the US website. I do not know if there are any operational or performance differences.Installation was a challenge that would have been eased by a deeper box. I recall that it was hard getting the Lutron to fit because there are three cables entering the box: line, lights and outlets. The Lutron doesn’t need the neutral and has a bare, small gauge ground wire but the Kasa looks fractionally deeper, needs the neutral connection and has a heavier gauge, insulated ground wire. Taking together one or two larger wire nuts and the Kasa being fractionally deeper (maybe only a millimetre or so), I had to really jam it all in. One side is still lifted off the wall but it’s in a workshop/storage area so appearance is not so important.Motion sensitivity even at 30ft is good (set to high sensitivity). Took me a bit to find my way into the device settings on the app and was relieved to find that the turnoff delay after motion has not been detected could be set to something longer than the default 1 minute. That’s also not something that is described on the Amazon page.

I recently added the KS200M motion-sensor light switch to my mixed suite of home automation devices, replacing a similar Incipio switch that failed. The TP-Link switch was a little more expensive than some alternatives, but in general my TP-Link Kasa devices have been a little more trouble-free than other brands. And it works fine, so 4 stars for sure.But it’s a bit annoying that TP-Link still has some easily-fixed annoying flaws after years of customer feedback.Most annoying issue with motion-sensor smart light switches (not just TP-Link), why isn’t there a easy way to temporarily override the automatic timeout when you want the light to stay on? Like when you are working in the room just out of view of the motion sensor, or sitting still in the room?As for the Kasa UI, why isn’t there a custom timeout setting instead of a limited choice of timeout values like “10 minutes” or “20 minutes”, but no way to set “15 minutes”? Don’t they realize that apps have access to a keyboard where you could actually type a number (gasp!) ?And it would certainly be more flexible for home automation if they exposed the motion sensor as a separate device. Yes, you can trigger actions based on the light turning on, but that’s not always what you want.
