Review: Inexpensive, easy to set up and use and tons of functions. Buying more! - 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 desertcart 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.
Review: 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.

## Questions & Answers

**Q: Does the switch face fit into a standard gang face plate? I want to install this into an existing 2 gang face plate but am concerned it won't fit.**
A: I just installed it into a single gang box that previously had a Decora face plate.  After removing the old light switch,  IN ORDER TO FIT THE BULKIER HS220 I HAD TO DRASTICALLY TRIM THE 8 WIRES THAT WERE IN MY GANG BOX :  five 12-gauge wires (2 white neutrals in a wire-nut, 2 black hots in a wire-nut along with a red "line" wire that connected the hots to the light switch), two 14-guage wires (1 white neutral, 1 black "load" wire), and 1 long ground wire that was connected to a bunch of short ground wires.       Before trimming it seemed like there was absolutely no way it would fit, but I gave it a shot and it worked.  I trimmed off a full 33" combined from all of those wires (the 12-gauge wires each 4.5" longer than was needed, while the 14-gauges were each 3" in excess, and the long ground wire was 5" in excess).    I am glad I had a wire-stripping tool at home, otherwise this would have been much more difficult; with the wire stripper it was easy, but still time consuming.

**Q: Will this control 3 lights in the same fixture? One review says no**
A: I have no idea what that reviewer is referring to and their review is inaccurate.  This dimmer will control 3 and more lights in the same fixture with no problem.  I have one controlling 6 LED lights on one fixture and another controlling 2 pendant lights on the same circuit.

**Q: can I dim the lights using alexa?**
A: Yes - for more information regarding Alexa voice commands, please see our helpful FAQ here: https://www.tp-link.com/us/faq-1356.html

Regards,
TP-Link Support

**Q: I have power but no lights?**
A: You must be careful which "black" wire goes to which connection on this device.  You must connect the "Load" and "Supply" as indicated on the switch.  If the switch does not turn on the lights, it is likely the "Load" and "Supply" wires are reversed; try swapping them and retry turning on the lights.

### ⭐⭐⭐⭐⭐ Best smart home devices ever
*by M***E on December 3, 2025*

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.
