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

Probably the best 3 way switch I have used that works with Apple Homekit. Mind you I haven't ever used the most popular branded HomeKit switch brand made by Lutron. But for someone who wants two physical switches that can be placed in a 3 way circuit, I don't think you can find a better option. You do have to be mindful of the instructions explaining how to wire the switches up depending on how the line/load wires come into the switch boxes. It's incredibly easy to install though, and the dimmer function is also fantastic. I first connected everything up and immediately tried out the dimmer to find that my lights only worked for the first 4 or 5 dimming settings while the rest did nothing. I was a little bummed but figured I could work around that, and then when I went to set up the switch in the app it actually had a section specifically for configuring the dimmers to work with your specific lights by calibrating them. After doing that everything works perfectly! I only have 1 3 way circuit in my house, but if I had more, I wouldn't hesitate to simply purchase these for those areas too. I'm very happy with this purchase and highly encourage others to give this a shot.

Very easy setup, and their app works well too. Never had a problem with Tapo/TP-Link devices. Well made and integrates with Alexa and Google Home.

These work super well and look better than my other smart switches from other brands. I love that you can set dimming level while off, and then it turn it on - on the primary switch little LED lights show you the current setting. Subtle and elegant. In my opinion these have a nicer feel than other brands, the little ring light LED is never too bright and functionality is great. The Matter support is fantastic, you can add to any Home app super easy without even using the official Tapo one. I still do for firmware upgrades, but I don't even think it's necessary. Had similar Kasa switches before which are visually identical, but the next gen Matter support means I'll be replacing most of my smart switches with these ones over time.

Install was straight forward only issue is that the base is large very tight fit in a 3 gang box. Great instructions and easy connectivity of both traveler wires. This requires a neutral wire to power the main switch. The satellite switch also easy to connect. Make sure to put electrical tape over the screws of the traveler wires. Connectivity to Deco mesh was very easy.

Easy installation if you're comfortable doing your own basic electrical wiring, with lots of instructions. The switches function nicely with a large LED lamp we have in the kitchen, and the fade is smooth. It connects easily to the native app and, in turn, to Google Home. For the price, I don't think you can beat it.

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.

They work great. I probably need to calibrate them better.

Be careful when buying this product. You can not use this product to replace your 3-way switches in a 4-way setup. You can use its counter part the "S515" without the "D" in the name, for dimmer. I don't like the fact that you have to install both switches ( the main and remote) at the same time. I get it from a dimming perspective but the basic setup should allow for you to install the first one, check the wiring, not have dimmin,g then install the second one, check the wiring, and have dimming. I found the calibration process via the app to be misleading and unclear. The dimming animation was suggesting it was testing when it wasn't. I love that it does power monitoring and has control for how to handle lost of power. I like that the Tapo app brought in my existing TP-Link products, but I don't like that they have multiple apps and should just standardize to one app. The price was good, so I would consider this product again. It is less than half the price of my Lutron Caseta switches and offers more functionality.

Excelente producto, es un kit para controlar una luz desde dos dimmers; ideal para escaleras o garage

The dimmer feature is a good selling feature. This Kit is a matched pair. It only works if they are used together. Other than that, it is easy to setup and works well with Google Home via your Tapo account.

Quality is there, always satisfied with TP-LINK

Work as intended. Took me some time to figure out which electric box to install the main switch and which to install the satellite. The installation is easy. FYI, the easiest way to initiate Matter pairing is pressing the restart button.

The product itself is great, but Amazon shipped clearly used units to me instead of new ones.
