TP-Link Tapo Matter Smart Light Switch: Voice Control w/Siri, Alexa & Google Home | UL Certified | Timer & Schedule | Easy Guided Install | Neutral Wire Required | Single Pole | Tapo S505(2-Pack)

These worked great for my application - dimming undercabinet LED lights. I connected this to a 24V dimmable LED driver (B0CPLLMKHH) that supports triac dimming and fits in a single gang box. The driver was connected to 24V dimmable FCOB LEDs (B091KG5K1Q) that will be in some aluminum channel. No flicker, no noticeable delay and super easy setup. I already have several light switches from Tapo, but these were the first Matter ready ones, so I was surprised when I opened my phone and Google assistant was asking for the number or to scan the QR code. I scan the code, named the device and it was done. Then when I opened Tapo app, it too just wanted me to name the device and location. I will say that the Tapo app handles the dimming better in that as you are dragging the slider the lights dim live whereas in Google, you have to let go of the slider for it to actually send the value to the switch. I also tested the voice command and it worked as expected, so that is great too. The switches come with faceplates that have hidden fastners, which I like, however I don't use them anywhere else in the house, and these switches will get in a multi gang box, so they will end up in the trash, which is a shame. Overall, I'm very happy with my purchase.

Although the instructions for the smart app use could have been clearer and it would have helped if the QR codes had not been at the bottom of the box, the wiring diagram for install was good. The recognition of the switch by the Apple Home app worked seamlessly and the Home app led me through test of install (app made the network connection supplying password etc). Installation of my second switch took 20 minutes or less. I am using sunrise-sunset control (Home app option), working well. I had considered using light sensor bulbs, these switches are effective, provide more control options and are more economical. Could not be happier, with the function of the switch, integration with my Apple Home app (instructions call the app “Matter”) and designer look of the switch.

Reliable switch, great firmware, app, and customer service support. This is the switch that you would expect from an excellent networking company! Well done Tapo / TP Link! I have approximately 30 of the dimmers and 3 or 4 of the on/off switches running in a Home Assistant-controlled smart home. For those of you with HA - your best bet is to go through HACS and download the Tapo Controller. If you're not using Home Assistant, well...what are you thinking? The dimmers & switches are ultra-reliable, fast-acting, and seem to have some baked-in self-healing WiFi routines. Nice work software/firmware team! Even after power is cycled on multiple breakers, the switches continue to try to re-establish their WiFi connection. Over a few days, they all return to the "white circle", fully connected status. If you're impatient, you can press the right button below the main switch on each of these to power cycle the switch and re-initiate the WiFi connection process. Some of these dimmers I am running as no-load remotes to control multiple other bulbs and switches. Even in those applications, response time is almost instant. The command always goes through and usually with imperceptible delay. Okay, so I've had these installed for about 20 months now and I haven't been without issues. I had an overnight failure of ten, yes 10 of the dimmer switches right around the 18-month mark. They were on separate circuits and kind of all over the house, some were right next to another dimmer that did not fail in the same junction box with the same hot/neutral/ground lines attached. While it looks a little like a failed firmware update, I just don't know for sure. There was no storm or electrical activity that night and nothing else in my electronics-heavy home was damaged. Anyway, TP Link honored the 2-year warranty. Yes, I had to jump through a few hoops, mostly answering honestly too many questions and return shipping is on the buyer to get replacements. It also took about a month, which is too long TP Link! But I did it all through the proper channels and TP Link did replace the failed switches with brand-new units. Overall, this is a really solid product from a reliable company. I do think at a budget price-point, this is the best choice for Matter-over-WiFi for North American smart home users. Would Matter-over-Thread be better? Almost certainly! It's just not available yet. (Hint, hint TP Link.)

I recently installed the TP-Link Tapo S505 smart switches in my home, replacing an older 3-gang setup, and I’ve been really happy with how smoothly everything went. One of the first things I noticed is how much slimmer these switches are compared to older smart switches I’ve used. That might not sound like a big deal, but when you’re cramming three switches into one box with a bunch of wires, every millimeter counts. The reduced thickness gives you way more room in the back for wire management, which made the install way less stressful. And since they’re UL certified, I felt confident they’re safe to use without cutting corners. Wiring was surprisingly simple—especially the fact that either black terminal can be used for line or load. That’s a small but huge win because it means you don’t have to stress about matching the exact wire to the exact terminal. For someone who’s done a few DIY electrical jobs, that flexibility saves time and guesswork. The app setup was fast and intuitive, and within minutes, the switches were online and responding. I already use a bunch of TP-Link devices, so I’m familiar with their app, but even if you’re new, I think you’d find it straightforward. Bonus: once they were in the Tapo app, they showed up instantly in Home Assistant, which I use to control everything. No weird delays or pairing issues. The only thing to remember is that these need a neutral wire, so they won’t work in older setups that don’t have one. But if you’ve got the neutral, these switches are a solid choice—especially at this price. They’re reliable, responsive, and blend well into my smart home setup. I also like using the scheduling and timer features to turn lights on/off automatically.

I had started on my smart home journey many years ago and had initially used Belkin Wemo switches for my light fixtures. The Wemos never worked well, and I had switched them all out a number of years ago, replacing them with TP-Link Kasa switches, which have been trouble free and worked great with both Alexa and the Kasa app. I have 5 Kasa dimmer smart switches and I recently decided to add another one. In my search on Amazon I did find the Kasa switch but also saw that there was a newer model, which is this Tapo model. It looks to be the same as my Kasa switch, but also supported Matter. The Tapo switch looks and installs just like the older Kasa model. With installation, it's straight forward, but key is having the neutral wiring as not all homes have them. You will also need to be a distinguish between the line and load wires (not important in older switches), so having a non-contact voltage tester would be helpful. The hardest part of the installation is tucking away the wires to get the switch to fit inside the wall box. The snap on cover plate gives the switch a nice clean look. With the switch installed, the next step is adding it to the app. It does not work with the old Kasa app, but the good news for me was that the Tapo app will work with my older Kasa smart devices. I downloaded the Tapo app and signed in with my TP-Link account, and it immediately populated all of my Kasa devices. Adding this switch was easy, just clicking on the "+" button and selecting the product. It found it right away and only took a few minutes. I have always liked the Kasa app and the Tapo app looks to be even better, as it's intuitive, though I will need some time to try out the features. On my Alexa, I did unlink my Kasa skill and then linked the Tapo skill, though not sure if I really had to do that. Alexa found the Tapo switch right away and works as expected in controlling it. As Tapo supports Matter, I did also add it to Apple Home Kit. None of my older switches support Home Kit, so this is the only smart switch on Home Kit. To add to Home Kit, it just requires the QR code from the device, which I did not find in or on the box, so I initially thought it's probably on the back of the switch, which didn't make much sense to me. However, in looking at the device in the Tapo app, there was an option to show the QR code, so problem solved. Adding to Home Kit was also quick and easy once I had the QR code. I have over 2 dozen TP-Link smart devices in my home setup. All of them are in the Kasa line except for this new Tapo switch. I can attest to the quality of their devices and am happy that TP-Link is continuing to bring new functionality to their line.

Install was very straightforward as long as you have a little knowledge of home electrical. Connected to our home wifi right away and integrated with Apple home seamlessly. Also nice to have the function to manually turn the switch on and off while keeping automation schedule.

Excellent switch, ease to install and control. Just need to replace un interruptor and look great. Works as I expected.

The gold standard for this type of switch is the Lutron Caseta series. The latest Diva models look and work like any other Decora lightswitch, and Caseta devices are absolutely rock solid. They just work. The TP-Link Tapo... not so much. Unlike the Caseta, the Tapo requires a neutral wire to work. That's fine in recent construction; the most recent NEC requires neutrals in switch boxes in new construction. But for most houses, a lot of switches don't have a neutral available. Once installed, you have a short period to get the Tapo to pair with your Matter-based smart home system. I spent a good half-hour trying to get it to pair to Apple Home using my iPhone. It utterly refused to pair, despite following every instruction and troubleshooting FAQ to the letter. I finally tried using my iPad instead, and that worked. Why this made a difference, I don't know. Matter is new, but I haven't had a problem pairing other Matter devices from other vendors. The Matter pairing code is on the front of the device; you have to remove the faceplate to see it. There isn't a spare copy in the manual, and there isn't a QR code on the device, so you have to enter the code manually. That's inconvenient. The switch looks like a standard Decora switch... that's turned on. It's not a rocker like the Lutron Diva; it's one pushbutton, hinged at the top, so it's much stiffer if you push the top of it by reflex. When off, there's a white circle light visible at the bottom. That might be annoying in some rooms. After the Tapo has been operational for a few hours, it becomes noticeably warm to the touch. Not dangerously so, but warmer than you'd expect an on-off switch to be. That suggests it's using a fair amount of electricity sitting idle. (Lutron's products remain cool to the touch.) When you turn the Tapo on or off, the "ping" of the internal relay is readily audible. It's one of the loudest smart switches I've used. It's not a show-stopper, but it's another reason why the Tapo might not be a great choice for a bedroom. Lutron's smart switches have a tab at the bottom you can pull out that turns the circuit off in hardware, so no one can turn it on remotely. That keeps you from getting shocked by accident if someone remotely powers a circuit you think is off. The Tapo doesn't have that. Instead, it has two buttons: one to reboot the device, and one to reset it. It's a bit concerning that TP-Link thinks you'll need to reboot the device often enough that it needs a dedicated button for the purpose. (I think I've had to reboot one Lutron Caseta device in ten years of owning a bunch of them; the hard-off tab power cycles it just fine.) The Tapo doesn't use a hub. It doesn't support Thread, so you don't need a Thread border router. It connects directly to your Wi-Fi. That may be convenient, but it means every Tapo switch consumes another IP address on your network. Too many of them, and you could run out, especially if you're not good with networking. That's one GOOD thing about smart-home hubs like Lutron Caseta or Thread. That said, I did eventually get it working, and it seems to work fine. It responds quickly to HomeKit. It's a fraction of the price of a Lutron installation, especially if you don't have a Lutron hub yet. If you don't need dark and quiet and cool from your light switch, it's a reasonable deal. But it's still slumming it compared to the Lutron.
