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

I am a novice in these things and was able to figure this out by using the wiring diagram provided in the box. This switch surely works for a 4-Way setup.

TP-Link Tapo Smart Switch – Single-Pole / 3-Way / 4-Way, Matter Compatible This is another useful piece in the TP-Link Tapo smart home ecosystem. In my house I run more than 50 Tapo devices including dimmers, switches, and smart outlets. These switches are especially helpful when dealing with multi-location lighting setups such as 3-way or 4-way circuits where the same light is controlled from multiple switches. Tapo does a good job covering these situations so you can still integrate those circuits into the rest of the smart lighting system without complicated workarounds. Installation was straightforward and once added to the Tapo app the switch worked just like the rest of the system. It integrates easily with routines and voice control through Alexa, and the Matter support allows for fast local response even if the internet connection drops. Like the other Tapo switches in my house, it has been stable and reliable over the past year of use. If you’re building out a larger smart lighting system and run into a multi-switch circuit, it’s nice to know Tapo has an option that fits right into the ecosystem.
