- Reviewed in the United States on April 16, 2023Color: White, Alexa CompatibleSize: 1 PackVerified PurchaseOnce upon a time, I was just an ordinary person with a boring old light switch. But then, I discovered the Kasa Smart Dimmer Switch HS220 and my life changed forever. This switch is truly a game-changer and I can confidently give it a 5 out of 5-star rating.
First off, let's talk about the installation process. I was a bit nervous about this at first, as I'm not exactly a handy person. But much to my surprise, the installation was a breeze. All you need is a neutral wire, which my house had, and you're good to go. No hub required, no complicated wiring diagrams, just a simple and straightforward process.
Once I got the switch installed, it was time to put it to the test. And let me tell you, this thing is incredible. The Kasa Smart Dimmer Switch HS220 allows you to control your lights with your voice, through Alexa or Google Home, or through the Kasa app on your phone. It's so easy to use and the dimming feature is truly a game-changer.
But the real standout feature for me is the scheduling option. You can set your lights to turn on and off at certain times, which is incredibly useful for when you're away from home. It gives you peace of mind knowing that your home appears occupied, even when you're not there. Plus, it's just fun to mess with your friends by having your lights turn on and off at random times.
I have to say, the Kasa Smart Dimmer Switch HS220 has truly revolutionized the way I use my lights at home. I love that I can control the brightness and color temperature of my lights with just a few taps on my phone, or by asking Alexa to do it for me. It's also really handy when I'm settling in to watch a movie or read a book, as I can dim the lights to the perfect level of brightness without even getting up from my seat.
But what really sets this switch apart is the fact that it's so easy to use. Even my technologically challenged grandparents were able to figure out how to use it with no problem. And if they can do it, anyone can! The app is really intuitive and user-friendly, and the instructions that come with the switch are clear and easy to follow.
Another great thing about the Kasa Smart Dimmer Switch HS220 is that it's incredibly reliable. I've never had any issues with it disconnecting from my Wi-Fi or failing to respond to voice commands. And on the rare occasion when I did have a question or problem, the customer service team at Kasa was quick to respond and really helpful.
One of my favorite features of the Kasa Smart Dimmer Switch HS220 is the ability to create scenes. With scenes, you can set up multiple switches to control different lights at the same time. For example, I have a scene called "Movie Night" where I dim the lights in the living room, turn off the overhead lights, and turn on my table lamps to create the perfect atmosphere for watching a movie. It's so convenient to be able to control multiple lights with just one command!
I also appreciate the safety features of this switch. It's UL certified, which means it meets rigorous safety standards, and it has a built-in safety shut-off feature that prevents the switch from overheating. This gives me peace of mind knowing that I don't have to worry about any safety issues.
Finally, I have to mention how great the Kasa app is. It's so easy to use and has a ton of features that allow you to customize your smart home experience. You can set schedules, create scenes, and even monitor your energy usage to see how much money you're saving on your electricity bill.
Overall, I would highly recommend the Kasa Smart Dimmer Switch HS220 to anyone looking to upgrade their home. It's easy to install, fun to use, and adds a touch of convenience to your daily life. Plus, it's just plain cool to be able to control your lights with your voice. So go ahead and buy it, you won't regret it!
- Reviewed in the United States on April 2, 2025Color: White, Matter CompatibleSize: 3 PackVerified PurchaseI love the Kasa switches. I’ve been slowly switching over to them. I was using another brand, but I think the Kasa works better and offers more options. They are easy to program, work with your Wi-Fi and dim well. I have Kasa switches that are several years old that have never given me a problem so they seem to be very durable. They integrate with Home Assistant and Kasa also has their own application. They also work well with Alexa.
- Reviewed in the United States on April 17, 2025Color: White, Alexa CompatibleSize: 3 PackVerified PurchaseI can’t overstate how much I love the Kasa Smart Dimmer Switches (HS220P3). These things are life changers. When we moved into our new home, one of the first things I did was order a pack of these. Our previous house had them installed, and I knew I couldn't live without them.
It might sound dramatic, but once you experience the convenience of smart dimmer switches—especially paired with Alexa—you’ll never want to go back to regular wall switches. Whether I’m watching a movie and want to dim the lights without moving a muscle, or setting the mood for a cozy dinner with one voice command, these switches make it effortless.
The dimming is smooth, setup is straightforward, and the Kasa app gives you total control (even when you’re away from home). It’s the kind of upgrade that quietly elevates everyday life—you don’t realize how much it improves things until you’ve used it.
If you're building a smart home or even just looking to make your evenings a little more magical and convenient, start here. Highly, highly recommend.
- Reviewed in the United States on January 13, 2021Color: White, Alexa CompatibleSize: 1 PackVerified PurchaseI recently installed a few WeMo switches so I could test them out, but found they weren't well designed and I wasn't particularly happy with them. So I started searching around for a new smart switch (Dimmer), and ran across the Kasa switches. I went ahead and purchased one to test it out.
Installation: 5 stars, super easy and much better in my opinion than the WeMo switches. Main wires screw onto to the switch plate, and a couple of wires run off to attach with nuts. WeMo had all wires run off to attach with wire nuts which resulted in large amounts of wire and clutter behind the switches making them much harder to work with.
Application: 5 stars, switch was immediately recognized and I had no problems with the application. Unlike the WeMo switches where I had several that had significant problems connecting, and they constantly disconnect. The Kasa switch has had a couple of times where the physical switch didn't work for a short period of time, but the app has always worked even when the switch didn't, and then the following day the physical switch would again work. Not sure if that is the result of a bad switch or if something else is going on, but ultimately it is a relatively minor issue as I can always use the application to turn the lights on or off if needed.
Wireless: again the setup and connection were easy, and I haven't had any problems with the switch staying connected to my network and always being accessible via the application. I have loads of problems with this on the WeMo switches.
Design: The design is much more well thought out from the wiring to even the physical function of the Switch than the WeMo version. WeMo uses a capacitive touch plate that runs the entire length of the switch. This results in the dimmer level constantly being change, turned off, etc... whenever you turn the light switch on or off because almost the entire switch is capacitive touch. Kasa on the other hand has their dimmer buttons at the very top of the switch so they are never in the way but are very easy to access.
Quality: Quality seems to be on par with the WeMo, but the design decisions were clearly well thought out. If feels like someone actually tested the Kasa Switch, while it feels like no one actually ever tested the WeMo switch design of they would have easily seen and addressed several of the blatant issues it has.
Note: there is one oddity with the Kasa switch, you may consider it a good or bad thing, but when turning the switch on/off there is a slightly delay (maybe 1-2 seconds). It caught me off guard at first and made me think the switch wasn't working properly. I'm still on the fence on whether this is a good thing or not, I think I prefer the instant switching action, but I can see why some people might prefer the delay and once you realize it is there it is honestly not a major issue.
The Kasa Dimmer switch isn't perfect, there are a few oddities to it, but it generally functions well, it seems to be far more well thought out than the WeMo switches and is significantly more reliable as a "Smart" switch. If you are trying to decide between Kasa and WeMo, don't wait, go with the Kasa switches, they are significantly better in almost every way than my WeMo Switches have been. At some point I will be replacing the rest of my switches with the Kasa Switches and removing WeMo entirely from my house as they just have way too many problems with them.

- Mark My WordsReviewed in Canada on March 29, 2023
5.0 out of 5 stars Very happy so far!
Color: White, Alexa CompatibleSize: 1 PackVerified PurchasePhysical installation was easy. (Obviously, it does help to be comfortable doing basic electrical work.) Each of the Kasa dimmers I installed was easily identified by the Kasa app on the first try. The app is friendly and will walk you through the wiring but also lets you skip all the directions if you don't need them. Since then, they've been working flawlessly.
I picked the Kasa dimmers over other makes because I felt they best matched the other decora switches in our home. I have no intention of replacing them all, so they need to look right together -- the ones we have installed so far are working flawlessly with Alexa routines to automate outdoor lights with switches at the front door. OH... and you can turn off the light on them -- I left just one strategically selected dimmer light on all the time so it's easy to find at night. (You can see which one that is in the photo.)
I also installed two more at the front door for pot lights and the chandelier to (1) match, and (2) provide some dimming because otherwise the chandelier is really bright... and these cost no more than a traditional mechanical dimmer switch so it's a "no brainer".
My ONLY complaint is that the faceplates that comes with these are REALLY tight fitting. Removing them right out of the box is tough enough - I can't imagine removing one when it's on the wall. However, I have used these Kasa dimmers with standard multi-switch decora wall plates so I may never know if the Kasa faceplates are as immovable as I expect.
Overall, VERY happy with these after a month or two of use.
