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

The **Tapo Smart Light Switch** is a **sleek, reliable, and user-friendly** smart home upgrade. It supports **Alexa, Google Home, and Apple HomeKit** for effortless voice control, while its **Matter certification** ensures smooth operation even if Wi-Fi drops. Installation is **simple**, and features like **scheduling, automation, and Away Mode** enhance convenience and security. A great choice for energy efficiency and smart living!

These are some of the best smart switches I have installed. They pair quickly, are Matter compatible so I can put them on HomeKit in the Apple environment. My only gripe is that for the fan switch the HomeKit recognizes it as a light switch, and there's no way to change it. Regardless, these are highly recommended, I have used Meross and other smart switch brands, but nothing comes close to relaibility, speed of reactivity and durability as Tapo switches.

The media could not be loaded. Purchased two Tapo S515 to replaced my Kasa KS200 because I wanted the energy usage feature. What a BIG mistake! The S515 and KS200 are basically the same light switch except that the S515 is newer and has data on energy usage. After installing the S515 as single pole, I noticed in the Tapo app that the S515 light switches would randomly turn on and off by itself (see attached video where the top 2 switches are the S515 and the next row of 2 switches are the KS200. I physically checked the lights and they were not turning on and off but the Tapo app was getting data from the S515 light switch that it is. I contacted TP-Link tech support and worked with them for over a month to get absolutely no where. Spent a lot of time helping them! Their engineers had me do tests and update to a new firmware that they just released because of my reported issue so that they could check the logs. Wasted so much time trying to help them and they couldn’t figure it out at the end so I decided to reinstall my KS200 and gave up. Hopefully one day they will fix this bug but the S515 is not ready for prime time. Imagine having a whole house with S515 switches and having your Tapo app look like Christmas lights blinking randomly on and off. If you check Reddit, other users are having the same issue installing it as 3 way, so it’s not the type of installation (single pole or 3 way). It’s either a problem the firmware or hardware.*** UPDATE as of 2/19/25 ***TP-Link Tech Support went out of their way to make things right. Therefore, I upgraded my 1 star rating to 4 stars. Once they have a permanent fix to the issue reported above, I will be happy to upgrade to a 5 Star rating.*** UPDATE as of 3/25/25 ***TP-Link Tech Support informed me that an updated firmware has been released that resolves this issue. I have not tested it myself as I opted to reinstall the KS200 that didn't have any issues. I will take their word that this issue has been resolved.

I agree with others that it "feels cheap" but you'll likely never notice once it is installed. Screw terminals for hot and neutral eliminate a couple of wire-nuts in the gang box (replacing a Wemo), so there's more room. Matter setup is simple, app setup is simple. Handles my mesh WiFi better than Wemo. Connects faster, responds faster, no dodgy Alexa skill needed for integration. All at 1/4 the cost. Belkin Wemo can go to...

I started replacing single pole switches with Kasa smart switches. This was the first 3 way I had to replace. Here is my setup, 3 separate switches, powering on 4 lights in the hallway at the same time. I shutoff the breaker, looked at the wires of the center switch, which I think had 2 traveler wires and 2 power wires. That didn't seem like the correct spot to put this switch. I then looked at the first switch in the sequence, which matched the inputs of this smart switch. Disconnected the original switch, connected the two traveler wires, line in, neutral and ground. Flipped the breaker and to my surprise, it all worked, zero issues. Just ordered new, regular switches for the other two spots as I need paddle switches to match the rest. Integrated this switch with Alexa, all good.

Switch works great, installed using Matter to connect with Google Home.Note that unlike some other smart switches, this uses only ONE smart switch per circuit, the other 3 way switch (and 4 way switch(es), if using) should be regular dumb switches.This also means:- You can only install this switch at the load or line end of the circuit, not the middle -- so you may be limited in which switch gets replaced with this smart one- You only need a neutral wire in the one box you're installing this switch in. (This finally let me install a smart switch for my 4-way hall light, which doesn't have neutrals in 2 of the 4 boxes.)- You can use a dumb 3 way dimmer at the other end, although that will be manual control only (worked perfectly for me, as the hall lights are too bright and so I keep them at 50% brightness all the time )Finally, note that the Tapo 3-way dimmer switch (TS515D) does NOT work this way - it only works for 3-way (not 4-way) and you need to replace BOTH switches.

I am using this switch with Home Assistant and it was easy to install, came online with no problems and operates as intended. However, the LED on the switch periodically blinks and, when this occurs, ON/OFF message pairs are being sent to the HA log. The controlled light does not actually blink. I have contacted TP-Link and they have provided updated firmware that reduces but does not eliminate these messages. Hopefully they can resolve it and I can update this review.
