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.

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.

I installed this Tapo Smart Wi‑Fi Light Switch to replace a traditional switch in my home, and I’m very pleased with how well it works. It lets me control my lights via the Tapo app, voice commands (Alexa, Siri, Google Assistant), and schedules — which is super convenient for daily routines and hands‑free use. I also like that it supports 3‑way/4‑way setups so you can control the same lights from multiple locations — perfect for hallways and staircases. The energy monitoring feature is a nice bonus too, helping me keep track of usage. Quick setup with the app was straightforward, though having a neutral wire in the switch box is required. Overall, this smart switch is a great upgrade from standard light switches — reliable and packed with useful features for a smart home. Highly recommend it!

I like my Lutron Diva and Caseta dimmers and switches more, because they use the Lutron hub and don’t clutter my wifi, but these have been good. Easy install, if you have done switch installs before. I liked that I could keep the original switch on the other side of the 3-way, so that you don’t have to buy 2. They respond quickly to manual and voice commands via the Tapo app or HomeKit/Siri and Home Assistant. They are less expensive than Lutron, look almost as good and work well. Also, the energy monitoring is useful. Lose one star because it uses wifi, vs Thread.

I installed 3 Tapo smart switches. Me: DIY person. Easy to install and super easy to connect and set up on Tapo App. [Appreciated]. I replaced two modern lighting electronic timer switches that have tiny screens and are not easy to program. The Tapo smart switch has an easy menu to program off and on times making it a breeze to control porch and patio lighting. Installation tips: 1. if the switch you are replacing is a 3 way or 4 way unit, the Tapo works perfectly but needs to be installed in the primary switch junction box. You can easily determine this by testing for current in the "line" wire when the switch is turned off. It will retain current when the switch is on or off. If the current stops when the switch is off, then that is not the primary switch in your 3 or 4 way set up. The included instructions explain this as well. Tip 2: verify your existing wire function before removing and installing new Tapo switch. While there are code and industry standards, the previous installer may have deviated. This includes verifying the traveller wires, often one red and one black, but this can vary. Also, the line and load [load goes to light in this case] wires may both be black. A noncontact voltage tester or multimeter can be used to discriminate. Tip 3: take pictures of old switch wiring before removal. This can help if you forget the wire origin. I removed and installed one wire at a time to minimize mix ups. Tip 4: The old wires may have been stripped too long which can expose the conducting copper after installed in the Tapo. This is easily fixed by snipping off any excess copper wire. Tip 5: The Tapo switch includes a single switch plate. If you are installing into a multi- switch junction box, the reused 2 or 3 or 4 switch plate cover will probably not fit totally flush over the top section of the Tapo switch at the screw hole because the switch body plate is a little thicker than a regular switch. I remedied this by shaving off small amount of plastic on the back side of the switch plate cover. ( see picture). This allowed a flat and flush mount onto the wall. I used a box cutter to remove a tiny amount of the plastic. Tip 6: Use of a power screwdriver (not a drill) saves time when removing and installing the two long switch mounting screws. Good luck on your project. Tapo smart switches highly recommended.

I had been waiting a long time for a simple no hub solution for 3-way switches and this was it. I have a lot of other Tapo switches and they work great and this was no different. As long as you can identify which of the switches in your 3-way arrangement is the line side and which is the load this goes in as easy as the single pole. Integrates well with both Alexa and Siri. Only real knocks on this is that the relay is a bit loud when switching and it’s a big block to go into the junction box. Took a bit of maneuvering and time to be able to get the wires cleared to get it fit into the box. However that’s not enough to take a star as is part of the trade off to having a smart switch and they are all like that and just took some extra time for wire management. I was also installing into a 4 switch box with one other smart switch already so was even tighter. Once the install is done it’s fantastic and does exactly what you need. The Tapo app isn’t amazing but it works and thanks to the Matter support it’s easy to hook into the smart assistants and manage it there.

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.

The Tapo Smart Switch works okay — when used in a simple single-pole or basic 3-way setup, it performs decently. It pairs with Matter readily, responds to commands, and integrates with smart-home systems without too much fuss. However — using the “all-in-one” version (single-pole / 3-way / 4-way combined) is where I ran into trouble. It seems like mixing those wiring modes in one unit introduces complexity that makes installation finicky and causes unreliable behavior. In my case the switch sometimes mis-behaved or didn’t stay properly synced, which defeats the purpose of a “smart” setup when you expect consistency. If you need a switch for a straightforward setup and don’t over-complicate the wiring, this works as a basic smart switch. But for more complex wiring or 3-/4-way circuits, this combined model feels like “trying to do too much,” and you may encounter headaches.
