Works flawlessly
It is full Apple HOME compatible. Installation is a breeze. Dimmer works as expected. Best is that it is physical which means that even if there is a network connection issue, you can turn the lights on and off. Best of both worlds. It also looks good. Definitely a good buy.

Fixed LED buzzing - high value product that does everything advertised
DIY homeowner here - This fixed my LED dimming issues! Background - I installed numerous Ensenior recessed LED lights and wanted a smart dimmer to control them, but my Feit dimmer switches were buzzing when dimmed. I purchased a Kasa single and 3-way switch and which solved everything. Kasa was easier to install than other switches, had better instructions, and the app is very good having step by step instructions in the app itself. Wiring was much easier with provided pigtailed wires on the device and it's easier to fit the device into the outlet box because it is slimmer than most other switches. The app works great to control the lights as well as the normal touch on and off function. I use inside outlet switches to smart control outside switches on a different circuit. Easy to recommend with high value product that does everything advertised. Much faster to install and start using than Feit.

Kasa smart switch
Kasa light dimmer works great with alexa. Easy install. Now I can turn the lights on and off or dim them by just asking alexa to do it for me.

No accounts needed. They just work!
Making your house smart shouldn’t be hard, and it shouldn’t involve creating accounts for the different devices you want to use. And it definitely shouldn’t involve giving up your privacy just so you can talk to your dining room lights. Until recently that’s what you had to do regardless of which smart system (Alexa, Google Home, Apple HomeKit, or Samsung Smartthings) you used. No system included everything you might want to use, your doorbell camera might be from Ring and your smart lock might be from Schlage. You’d have to create accounts in each then integrate them into your smart system. The new Smart home standard, called MATTER, attempts to change all of that by establishing compatibility standards for smart systems and devices without the need to create accounts or give up any privacy. If the device is MATTER compatible and your smart system works with MATTER, you just scan a QR code and the device is integrated. Simple, easy, done. If you’re a HomeKit user, this was a godsend. More smart device makers are adhering to the MATTER standards and these Kasa single pole smart dimmers shows just it should be done! Installation is marginally more complicated than installing a regular single pole switch. Once installed and powered, the dimmer works like any normal manual dimmer. The magic happens when you add the device to HomeKit. In HomeKit->add device, you scan the QR code. After about a minute HomeKit asks you a few more questions about how you want to integrate the switch. Answer those and you’re done! No new accounts or passwords you have to remember. The dimmers just work! Of course, Kasa would love for you to open an account so they can bombard you with info about other products they offer, but you don’t have to do it. The only reason you may decide to get an account is for firmware updates, but those are relatively rare. They look great too. I highly recommend these dimmers.

Works Well but Integration Could Be Better
The Kasa smart switch works great, with a full set of features and smooth control through the app. However, there is a minor issue: while it stays connected in the Tapo app, it sometimes shows as offline in Google Home when connected via Matter. Not sure if this is a Google Home issue or a Kasa issue, but hopefully it can be improved.

Great product
Super cool dimmer switch! We already had one installed that was loosing its wifi support. So I ordered a Matter certified Kasa product so we wouldn't have this issue in the future. It was very easy to install and i love the dimmer feature. I've had other kasa products thag have lasted 5 or 6 years now, and still going strong. Great product

Smart buy
Looks good. Easy install. Reliable connectivity from Kasa/Tapo products always. And good value for money as it's only slightly more expensive than a non-smart dimmer.
