TP-Link Tapo Smart 3 Way Dimmer Switch KIT, Matter Compatible, Energy Monitoring, Neutral Wire Required, Works with Alexa, Siri, Google Home, SmartThings, UL Certified, 2.4GHZ Wi-Fi, Tapo S515D KIT

Probably the best 3 way switch I have used that works with Apple Homekit. Mind you I haven't ever used the most popular branded HomeKit switch brand made by Lutron. But for someone who wants two physical switches that can be placed in a 3 way circuit, I don't think you can find a better option. You do have to be mindful of the instructions explaining how to wire the switches up depending on how the line/load wires come into the switch boxes. It's incredibly easy to install though, and the dimmer function is also fantastic. I first connected everything up and immediately tried out the dimmer to find that my lights only worked for the first 4 or 5 dimming settings while the rest did nothing. I was a little bummed but figured I could work around that, and then when I went to set up the switch in the app it actually had a section specifically for configuring the dimmers to work with your specific lights by calibrating them. After doing that everything works perfectly!I only have 1 3 way circuit in my house, but if I had more, I wouldn't hesitate to simply purchase these for those areas too. I'm very happy with this purchase and highly encourage others to give this a shot.

Replacing my kitchen 3-way switch was daunting. But by following the instructions and use electric meter to mark existing wires made it easier. I had to add green ground wires and found a neutral wire to use. It worked the first time controlling the light. I used Alexa to add my kitchen light and the QR code made it easy.

Installation was quite straightforward - as long as you can identify the load, line, neutral, and ground wires, you’re good to go. Take a moment to study your existing 3-way switch setup, especially the common and traveler wires, since this switch follows a similar wiring pattern. I’m not an electrician by any means; my only prior experience is replacing a few standard switches with smart ones. Despite my initial hesitation - especially after seeing it marked as a “Frequently returned item”- I went ahead, and honestly, I’m glad I did. It turned out to be easier than expected.As for the smart connection, thanks to Matter support, I didn’t have to rely solely on the Tapo app. I first added the switch using Matter via Apple Home, which automatically synced with the Tapo app, and then integrated it with Alexa through Tapo. Now I can control the switch from Apple Home, Tapo, and Alexa - a really convenient setup.

These switches are great you can adjust the lighting control from anywhere really convenient if you always forget to turn a light off

Item was exactly as described. Extremely easy to set up and program using their application. Works flawlessly with Amazon's Echo devices. Only been using for a few days but so far no unexpected turn on or off's. Was a great upgrade from my 30 year old X10 system.

Works well, highly recommended this dimmer switch.I replaced all my switches with matter supported tap switches and dimmers.

Great product support product.

Doesn’t work in a 4-way circuit with three switches.
