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

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.

I replaced an older set of smart dimmers with this. The other ones were somewhat unreliable at times. Installation was pretty easy if you've done this sort of thing before. It was a little hard to get all the wires in the box since I had a large GFCI and another smart switch in that box, but it all fit. Setup took a few times to work, but once it was setup, I've not had any issues. It's great to be able to dim from two locations with separate buttons on the switch instead of holding it down like many other switches require. Overall this is a good product at a reasonable price.

No problems found so far, but I notice that the “satellite” switch of the switch pair is lacking the little dimmer indicator lights. I don’t know why those would be missing unless the satellite can’t get that info from the primary.Also, if there’s going to be a primary and a satellite, I don’t get why they don’t consider multi-way configurations with more than one “satellite”.

Just put these in our house to replace our old smart switches that were no longer working. Install was fast after the first one. They connect easily to HomeKit and the Wi-Fi. Good value for the money. We love the dimmer function and that when you turn them off you can change it to dim slowly instead of straight off and on. Good replacement to our old brand.

Great switches for the price if you are going the WiFi route. Very easy to install with provided directions. App feels intuitive and compatible with SmartThings. Matter functionality is a nice touch for future proofing.

Like them for the use of apple homekit functions.

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

Works fabulous 👌 looks beautiful. Easy to install, great value, durable with my six children Banging on them
