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.

Why didn’t I do this sooner??
To be used, its a great item. Only issue i had was with a short cut ground wire on the satellite side …otherwise, respliced it and made it work. No issues, love the product for my hallway recessed night lights. Installation was almost a breeze besides the wifi hiccups! Instructions are clear, I have little to no knowledge to this and this felt very easy once I was able to determine the main line from the travelers.

Works Perfectly
Installed this Kasa 3-way dimmer in a hallway and it works perfectly. Wiring was straightforward, the app setup was quick, and the dimming is smooth with no flicker. Works great with Alexa and Google Home. Clean look and very reliable. Would definitely buy again

Have this setup in the garage and it does a pretty good job at detecting motion. You can change the settings to make it more or less sensitive which is also nice. Setup was pretty simple, don’t forget to make sure your breaker is tuned off :)It would get a 5 if it could detect the door as motion but I think it’s based off heat and only detects me once I’ve gone down one of the stairs (180 degrees in relation to the switch)Also, app is pretty good too, simple enough to use and the connectivity was easy. I like that Kasa has widgets available on iOS so you can toggle the light from your home screen (See screenshot). You can also set a timer for how long the light stays on after it stops detecting motion.

I have a house filled with a lot of Kasa, Tapo, and Omada devices throughout, and after a few firmware updates over the years they all work very well via Alexa.There are some things to consider when installing iOT devices.1. Don’t use standard grommets that use up valuable space in you 1/2/3 gang boxes. Look at using flatter connectors.2. Follow the installation instructions, and really read them. These are easy to install, but the Kasa devices all need a neutral wire.3. Do the initial firmware updates and use your App to check every so often. The bug fixes are important to.4. Some smart switches can be a pain, like the 3 way, especially when wiring in an older house. If you don’t have a red wire (14/3) it won’t work. I do have one that one side works and the other does not. Possible a problem with the traveller wire.5. For everyone who has a home network with 2.4ghz and 5ghz signals. Let all your iOT devices run on the 2.4ghz. Do not use tablets, smart phones, firestick or other media devices on this, use the 5ghz, trust me, you’ll see amazing improvements and a lot less dropped signals. Remember 2.4ghz usually can have only 32-64 devices depending on the router, and is prone to interference. Don’t waste your bandwidth, big devices…use the big signal.6. If you have 1 router in a big house, expect problems. Install a few EAP225s if you can (Cat 5e or better wiring and either a POE switch or POE injectors) will improve performance. Cable company routers and extenders usually are basic for a high price, and if they aren’t wored, they can be temperamental.Over the past 8years I have been installing TP link devices and their customer service is usually pretty good if you understand electrical and networking, if not you may struggle.In my opinion, TP Link has an excellent spread of devices for the home.I am installing their fan controllers next, and really hoping they make a solid smart thermostat that does not need a C Wire, or comes pre packaged with a solution.Since installing these devices and programming schedules, I have also seen a drop in my power bill…which is always welcomed.One more item to note: Only purchase from “Prime” which ships from an Amazon warehouse to ensure you get a factory fresh device.I hope this helps many who gave these less than 4 stars, I trust this brands performance after many years of use and their evolutions.
