Kasa Smart Dimmer Switch HS220P3, Single Pole, Needs Neutral Wire, 2.4GHz Wi-Fi Light Switch Works with Alexa and Google Home, UL Certified,, No Hub Required, 3-Pack

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.

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.

From solid experience using many Kasa smart devices, dimmers, switches and outlets, I am totally convinced that they are the best, easiest to install and connect to WiFi and most reliable smart home devices ever. Customer support is very helpful and friendly. Once I had a little difficulty to connect a dimmer to WiFi, it took customer support 5 minutes to help me connect it and gave me a valuable tip to make connecting any devise, not just Kasa but any smart home devices ever, to connect a smart home devise the cellular data has to be off temporarily until connection is successful. I rank Kasa (TP-Link) smart products, as #1.

Interesting installation: Two of the wires (ground, neutral) are fastened to existing wires in the switch box with wire nuts. But line and load wires need to be attached to the switch with screw terminals.. Since my old switch had the wires attached to the switch with push-wire installation, I had to remove the wires from the old switch, then bend the wires into a little “C” shape to install them onto the TP Link’s screw terminals, then fasten those down. This made the installation a bit more tedious, but it does save a bit of room in the switch box (as the wire nuts can be bulky and take up a bit of room). After some effort was able to fit the switch into the switch box, but it was quite a tight fit. This is a thick switch. Screwed it in (it’s in a 2-gang switch box with another decora/decorator-type switch that controls the bathroom fan) and tried to put on the Legrand 2-gang decorator switch plate, but the bottom of the plate would not cover the TP Links switch fully. There was a little annoying gap at the bottom, even with the switch plate fully fastened. I bought another 2-gang switch plate (by Leviton) and this was a midway switch which was a bit deeper.. thankfully this fit perfectly! So keep that in mind.. if you don’t use the included switch plate cover by TP Link, you’ll need a deeper, thicker switch plate cover to accommodate this thick switch. Leviton’s midway plate worked well for this. Now that the switch is installed it works great. Installed via the TP Link Kasa app, connected to Alexa and added to Home Assistant. The dimmer functionality works well and the switch looks nice. I am not sure how I like the switch feel when using the switch manually, though. It feels a little odd (not like a “real” click from a mechanical switch). Most of the time I use sensors and timers to turn the switch on/off, so not a big deal, but the physical switch itself doesn’t feel 100% like a real manual/mechanical switch. Overall I like it. It’s a great value for the price (less than $20) and it is UL listed, which was an important requirement for me.

We purchased this KASA smart dimmer switch to replace a similar switch that was installed when our house was built. That original switch was NOT a TP-Link product, and it did not connect with the KASA app, which is what most of our smart home devices used. We really prefer TP-Link and KASA connectivity because they are very user friendly. If the power or the Internet go out, these devices usually reconnect automatically. If they don't, resetting is very straight forward and quick. This particular TP-Link switch was easy to install, and once installed, was super easy to connect to our Wi-Fi. We love that we can adjust the lighting level from the switch or from the app. This switch controls 24 outdoor eve lights without any connection issues. Amazing! The switch also matches the look of other wall switches in our house. It's easy to use and very responsive. We are very happy with this purchase and highly recommend it to anyone who wants to install a single pole smart switch.

Very easy to install and pair with alexia. Works great

Update: I was able to get the switches to work. I missed a step in the process. Good switches. It would help to make the step of going to the wifi list to get connected more clear. at least for me. The app does not allow this switch to be connected. It is not listed on the app and none of the available options work. So, switch works, just doesn't do the Alexa voice command. Disappointing, TP Link is better than that.

Install was easy as was setup. Reasonable good quality. I will buy more.
