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 with Amica LED puck lights
We added a bunch of LED puck lights in our hallway underneath the AC duct, and it really brightened the area up – too much! It looked like a hospital operating room and my wife immediately told me we needed a dimmer switch. Looking at the literature for these lights, they have a short list of recommended dimmers, and this set was not on that list. They discouraged using smart dimmers completely, but that doesn’t fly at my house. All my lights and fans are connected to smart switches, and these hallway lights were going to be the same. I bought these Kasa 3-way smart dimmer switches and they work perfectly. The lights go really dim with no flickering, and they were really easy to tie into my Amazon Alexa system. We have had zero issues with connectivity, and I love that they have a ring of light about the size of a dime built into the switch when they are off so I can see the light switch in the dark to turn them on. The price is great for such a highly functional smart 3-way switch – definitely recommended!

Happy with my choice, but not entirely so
Installed quickly and easily, and comes with its own screwless trim plate. Once the power was turned on, pairing with the Kasa app was seamless and took only a minute or two (the LED on the switch is fairly dim, and I had to cup my hand around it to see that it was flashing orange waiting to be paired with the app). The on-off functions in the app worked perfectly. Pairing with my Alexa app was also pretty simple, but you have to look by alphabetical order for “TP Link-Kasa” in the long list of devices that work with Alexa instead of “Kasa” only.The reason I am knocking off one full star in my rating has to do with the motion sensor. In the device settings menu (the gear icon top right in the device page of the app) you can choose between FAR RANGE, MID RANGE and the default CLOSE RANGE. On the CLOSE RANGE setting you really do need to be within 3-4 feet of the sensor. MID RANGE is out to about 8-10 feet and FAR RANGE is not consistent, sometimes it only senses out to about 12 feet. My kitchen is 20-feet x 20-feet and the switch is necessarily on the far wall opposit the entry door. I have to walk almost halfway across the kitchen to trigger the light to come on. The Lutron Maestro switch that started to fail a week ago, which this Kasa switch is replacing, could easily reach beyond the kitchen door. Nowhere in the product description does it discuss the motion sensor range limits. So minus one star.But the fact this is a smart switch is also the reasons I bought it. I can tell my Alexa Echo Pop to turn on the kitchen light before I get there. The Kasa app has a wide array of settings for turning on the switch under different scenarios, such as when ambient light goes below a certain level, or to automatically turn on and off at specific times, as well as how long to keep the light on after it no longer detects any motion. You can also program the switch to delay the off function a number of seconds after pressing the switch, so you don’t have to walk across a dark room immediately after toruning off the lights. As a smart switch, you can program Alexa “routines” to turn the light off after a certain amount of time or tell it to turn off the light as I am leaving.But the two apps sort of compete against each other. Before I programmed a longer off time in the Kasa app, the default is one minute. When I told Alexa to turn the light off after 10 minutes, the light still went off after just one minute of no motion. When Alexa later turned the light off, the Kasa motion sensor did not turn the switch on until I turned it on manually. I’m not certain this is an anomaly or was just coincidence. The value of the Alexa app is the ability to group switches and plugs from different manufacturers (I have some Gosund plugs and switches also). You can “group” switches and plugs to control them all at the same times.

Super easy to set up and turn off lights on a schedule
Super easy to set up and turn off lights on a schedule. Installation takes 5 minutes. Set up and integration with Alexa is simple, and you can set up automation to turn off other lights when this sensor detects no motion. Highly recommend all Kasa products —great products and ease of use.

The Kasa KS230 KIT V2 is a fantastic smart switch upgrade. Setup was easy, and the app made configuration a breeze. Dimming is smooth, and remote control via Alexa or Google Assistant works flawlessly. The dual 3-way control is super handy, and the fade-on/off feature adds a nice touch. Sleek design, reliable performance — highly recommended for smart home enthusiasts!

Using this switch for more than a month now.Excellent product for hallways and entryways, helps conserve energy, and specially in a house with multiple stories, you wont have to go downstairs/upstairs just to turn your lights off.Installation is easy, and takes mere minutes. Fits perfectly with the 2-3 slots face plates as shown in the image. Remember to turn off your circuit breaker before installing :-)Wifi connectivity and integration with alexa is hassle-free and reliable as per my observation. I was particularly concerned about the wifi signal as my router is installed at a significant distance and on a different floor.Only issue i have observed, which is a rare occurrence, is that it detects motion without any human presence and turns the light on for the set amount of time. (Not too concerned with that as it happens not more than once or twice a week)

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.

They work well, were relatively easy to install as long as you found the the line side of the 3 way switches. Unlike what some people have said, you cannot separate these switches in order to use in 2 different 3 way switch circuits. This is because there is a very clear master and slave relationship. The master has a line for the power, and the slave switch does not. Therefore it will not work without the master. Perhaps earlier versions of Kasa’s 3 way switches were not built this way, but this version is.That being said, when purchase on sale, they were still more economical than other solutions that I found.I have not personally integrated with Alexa as I don’t use it, but I know that it can be done. I have used the App however and it is very easy to setup and I am very happy with the built in feature set. I especially love the away mode that many apps don’t have. This allows for the randomization of on and offs during a specified time frame as opposed to always coming on at x time and off at y time when you are away, therefore advertising that you are not in the house.I am very happy with these switches and have recommended them to others. I have not installed close to 20 in my own house and have no complaints.
