TP-Link Tapo Smart Switch, Single-Pole/3-Way/4-Way, Matter Compatible, Energy Monitoring, Neutral Wire Required, Works with Alexa, Siri, Google Home, SmartThings, UL Certified, 2.4GHZ Wi-Fi, Tapo S515

Installed a few of these Tapo smart switches and they’ve been excellent. Setup in the Tapo app was fast, pairing was smooth, and they’ve been rock-solid reliable day to day. The biggest win is Matter support — it makes integration with Alexa / Google Home / SmartThings straightforward, and it feels more “future-proof” than older Wi-Fi switches. The energy monitoring is also a great feature and gives useful insight into what different lights and loads are actually using. The switch itself looks clean, feels well-built, and the button press is firm (not cheap or mushy). Overall it’s a great value compared to other smart switches with similar features.

Used it for a 4 way connection, put it at the end of the loop so the other lights switches work, no issues

These are my absoulte favorite smart switches. Easy to install, way better than typical switches. Matter compatibility is awesome, and the primary reason I got this switch. It's fast, and I really like the light indicator when the light is turned off. One improvement I would like to see is a smart bulb mode that lets it work with smart light bulbs better, but it's a great switch.

It was fun learning about how 3-way switches work. I was lucky enough to have gotten the correct switch on my first try. What I mean by that is that this switch will only work on the light switch that has the line coming into it. Only one of the two 3 way switches have the (power) line coming into it. You'll need to know which one that is and attach to that one. I'd suggest figuring that out first because if, for example, you're upgrading all of your downstairs switches to be smart switches and not the upstairs ones but the upstairs one is the one with the line coming in, then you'll be in an awkward situation. Easily solvable by just getting a similar styled switch for downstairs that isn't smart, but it's something you should be aware of. Once installed, setup in the Tapo app is easy, as is connection to the Google Home. It's Matter enabled, so that's great for people who don't want to be attached to a cloud service provider (works with Home Assistant).
