Smart Switch, S515, Single-Pole/3-Way/4-Way, Matter Compatible | Works with Alexa, Siri, Google Home, SmartThings, UL Certified, 2.4GHz Wi-Fi

I purchased to automate the lights in my garage, tying it to when I unlock and lock the entry door to the garage. I needed a matter compatible 3-way switch and this does the trick. My garage lights are on a 3-way switch, which makes for a more complicated install especially if you're only replacing one switch vs. replacing both. For setup, it's important to determine which is the master and which is the slave as I would need to change out the master for it to work. Wiring it up requires connecting 5 wires. The first thing to note is that this switch requires a neutral wire, which older switches do not, so I only have 4 wires coming out of old switch. The Tapo and most smart switches require a neutral wire so first thing is to make sure your house wiring supports it else the smart function will not work. On the old switch, there's ground (easy to identify as it's usually bare wire) and then 3 additional wires for line and 2 travelers. One of my traveler wires was red making it easy to identify but the other 2 wires were both black. I initially installed the other two wires incorrectly mixing the 2nd traveler with the line. Once I turned on the power, the lights began flickering on and off. Easy fix, just needed to turn power back off and swap the 2 black wires between line and traveler. Once corrected, the switch was working. Now for me, the hard part was getting this module to fit into my box as it's bulkier, so it took effort to make it fit. First, adding to the Tapo app on my phone was straight forward and only took a few minutes to get it added. Next I wanted to add the switch to Apple Home which was also fairly easy as Apple Home found it right away, so I didn't need to use the matter code. The matter code can be generated in the Tapo app if it's needed. With this switch and my smart lock both on Apple Home, I was able to quickly set up simple automations to turn the lights on and off whenever the smart lock is unlocked and locked. I can also easily turn on and off the lights remotely with my phone. The switch matches the look of my other switches and and was perfect for my install into a double gang box. It does also come with a single wall plate, which would look great on a single gang install, but for my needs, I didn't use it. This switch does not dim, but that was not a feature I needed. Overall, this switch is a good value for the functionality it offers.

These smart switches work great! I’ve been using them to remotely use lights/give them schedules and I have no complaints whatsoever. They’re better than the old Leviton Smart Switched I’ve had in the fact that they connect to your phone without hubs unlike the Leviton switches which require a hub. They’re quick and easy to set up, look pretty nice, and are pretty fast wirelessly. Overall, these guys are a 10/10 switch and I recommend them.

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.

These switches are great, but lost a star due to a 3-way setup issue. They work but there is a setup warning to consider. The TP-Link Tapo in 3-way mode MUST BE CONNECTED TO the LOAD LINE, not the end line to the light fixture. You cannot just unplug a dumb 3-way and plug this one in, with the neutral wire and expect it to work. If your load line (the black screw) is connected to the light fixture, your light and switch will flicker on and off. This is because the switch must have always on power LOAD and NEUTRAL; one of the traveler lines is always hot, but the Tapo version does not take advantage of this. This is not the case if you have the TP-Link KASA version of the 3-way switch. The KASA was a swap any 3-way switch (with load line) and you were done; it took advantage of the traveler line load.

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 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.

Easy to install. Flawless behavior.

Bought to replace numerous Wemo Smart Switches, when I found Belkin was ending product support and servers in Jan 26. Supposedly switches and plugs installed, in the Apple Home Kit app, will still work post Wemo. Set up was definitely easier, compared to Wemo and the App is much faster to control switches and plugs. The switches and plugs also easily install in Apple Home Kit (I did have to reset two switches to get them to pair) and are Matter capable for future upgrades. The App does not allow Picons at this time, which the Wemo app did. Also the Tapo App will accept previously installed Kasa switches seamlessly. I had used a Kasa dimmer to replace a Wemo version that had failed and couldn't find a Wemo replacement. (Should have been a clue) I recommend you put the switch ID QR labels on sheet of paper should you need to reset in the future. My only issue is the switches do not support all 3-way wiring configurations. Only two out of six 3-way switches worked when installed in the same wiring set up as the previous Wemo or Standard switches. I had to install them as pole switches to get them to work. You have to tape off the other circuit switches or the light, etc. will not work if inadvertently activated, until turned back off. I found this note online (not noted in instructions): "Wemo 3-way switches are designed to work together in a circuit, allowing for control from multiple locations, while Tapo switches currently do not support this functionality. Tapo switches require a hub for certain automations and do not have the same capabilities as Wemo in a 3-way setup. (community.tp-link.com). Other users had the same issue. Other than the 3-way setup issue. I found the Tapo switches, plugs and App superior. The other benefit is they are much more reasonably priced.

No me sirvió, lo devolví y no me reembolsaron mi dinero. No confíes en este vendedor

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.

Atende perfeitamente seu propósito. Compatível com Energy do Smartthings, pode ser instalado wifi no app Tapo e depois via Matter no hub Smartthings. Fique sabendo do seu gasto energético com Tapo!

Perfect fit for smart home with 3 or 4 way switch. Make sure you have a non-contact voltage tester to see which is the master switch and once you done it the installation is easy and simple.

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