      I'm a long time user of the Kasa smart plugs, which have been operating flawlessly for me at several locations for years and all are on schedules. I had no idea Kasa made dimmer switches as I've always just stuck to Lutron dimmers. I saw these on a suggested product on Amazon and decided to give them a try. I've been using the dimmer switch for a about a week now. These ARE EXACTLY WHAT I WAS LOOKING FOR AND EXCEEDED MY EXPECTATIONS. I mean holy crap I'm impressed with the quality, ease of install, set up and functions. I'll be looking for other switches to replace with these. And for the incredibly cheap price (compared to lutron) I really couldn't be happier. I really like that I can use the switch with all functions at the wall as well as on my cell phone.

      5.0 out of 5 stars Excellent value, works well with Google
      Reviewed in the United States on January 22, 2023
      Color: White, Alexa CompatibleSize: 3 PackVerified Purchase
      I've installed more than 50 of these smart switches across several properties.

      Price-wise, these are on par with Lutron "dumb" switches that you'd buy at a big box store, and you get much more functionality.

      Installation is straightforward for anyone familiar with basic electrical work. It's a bit like a GFCI outlet, though- they are fairly bulky, so there's not going to be a lot of spare room in the box. It can be tricky to get two of these into a duplex box. (Waygo's, or very, very neat wiring are your friend)

      We use these with Google Home, and they work very well. The only complaint I have about the integration is setting them up twice- once in the Kasa app, and then again in Google Home. It would be great if the setup process were all in one place and just flowed through. For example, when i have "Living Room" in both apps, Google Home should realize that I've set up a switch in Kasa and automatically assign it to "Living Room" in Google. I realize that is on Google- it's just something that should be addressed.

      Once it is integrated, though, you can mimic a much more expensive home automation system. I've seen homes with $30k-$50K just on home automation. These switches do a darn good job of mirroring that, and they don't require a server to run them. We've set up "scenes" like "Hey Google, it's time for movies"- and then Google can address the various switches and dim the lights, close the blinds, etc. It's quite a luxurious feeling.

      What I particularly like about these switches is that they stay connected to our wifi pretty well. I've experimented with several other brands, and some of them will drop off the wifi on an annoyingly frequent basis. I want to install, then not think about it again. In my primary residence, we have >30 switched that have been running for about a year. Only one has ever needed to be reconnected to wifi, and that has only happened once so far. (btw, reconnecting is relatively easy, as there are reset buttons carefully hidden on the front of the device- you don't have to take it out of the wall).

      So all in, electronics are well designed, installation is about what you'd expect, and integration with Google Home is pretty good. Kasa has done a very nice job with these switches.

      Great product, the color match is just a bit off but it’s pretty close. The app makes it super easy to use and the installation took a total of 5 minutes. It does make a noise when turning on and off but so do most smart plugs. The brightness levels are super easy to set in the app and it’s honestly the perfect dimmer switch!

      4.0 out of 5 stars Solid Smart Features, Dimmer Adjustment Could Be Smoother
      Reviewed in the United States on March 2, 2026
      Color: White, Alexa CompatibleSize: 1 PackVerified Purchase
      This smart dimmer integrates well once installed. It connects reliably over 2.4GHz Wi-Fi, responds quickly through the app, and works consistently with Alexa and Google Home. Scheduling and remote control functions operate as expected, and once configured, it maintains a stable connection without random drops.

      The dimming function works, but it isn’t especially smooth. Adjustments feel a bit stepped rather than fluid, particularly when fine-tuning brightness levels. It’s functional and gets the job done, but it doesn’t have the refined, seamless dimming feel of higher-end dimmer switches. That’s the primary reason this isn’t a 5-star rating.

      Overall, it’s a dependable smart switch with solid connectivity and features. If you prioritize smart integration and remote control over perfectly smooth dimming transitions, it’s a practical option.

      The media could not be loaded.
      I am just going to come out and say it. We freakin love these things. over the last 4+ years of owning our home we have swapped out almost every single light switch in our house with these Kasa Switches.
      Models we have:
      Kasa Smart Light Switch HS200P3 - Your standard light switch
      Kasa Smart Dimmer Switch KS220P3 - This is your standard dimmer switch
      Kasa Smart 3 Way Switch HS210 - 3 way switch
      We are a Google family with the exception of our 12 year old daughter how has yet to see the light but we are working on it. These switches are all hooked up to Google Home so we can either get off the couch and flick the switch like an animal or we can simply say: Hey Google, Turn off the kitchen lights. we have everything grouped in Google Home by room and function of the switch which make it a breeze for even my kids to use. My wife is British and to be fair she does struggle with it understanding her from time to time but I do not encounter that problem so I am giving these bad boys 5 stars. They are a modern bright white that matches our home, the install was so easy that even a colorblind adult (me) could do it, initial setup is very easy but if you do change your wifi name and network details you will need to reconfigure them which can be a bit of a pain in the buttocks. We have only had to do this once and I do not recommend it. We like these so much we have even purchased them as a house warming gift for my ungrateful brother and he is also now hooked on the smart tech they offer. I recommend these and will certainly be buying more in the future.

      This was the first set of smart switches that i purchased and it was honestly a very confusing endeavor. there are just too many of them out there and a lot of mixed reviews. I ended up buying these on sale and honestly i am quite impressed. They were easy to install, easy to integrate with Google Home, and the app is super easy to use. As soon as you find the device, the firmware gets installed and you're good to go. I've lost electricity twice since they've been installed (not due to the switches) and they have never lost connection to wi-fi. They auto connect and without wifi still function like a regular switch. highly recommend this brand

      1.0 out of 5 stars No good for UK homes

      It’s designed for American homes which have a 110V supply. UK homes have a 230/240 V supply so it can’t be used in UK homes
