Matter Smart Wi-Fi Dimmer Switch | Tapo S505D(2-Pack)

I’ve installed multiple smart switches, and this TP-Link Tapo Matter Smart Dimmer was one of the easiest.Before shutting off the breaker, I removed the wall plate and used a multimeter to identify line and load. After cutting power, I labeled the wires using the included stickers, removed the old switch, and disconnected the pigtail ground from the existing ground bundle. The Tapo dimmer uses a long ground wire instead of a ground screw, which made installation straightforward. Everything fit back into the box cleanly.Setup in the Tapo app was quick and intuitive. Tap the plus icon, add a new device, and follow the prompts. One important tip: don’t skip calibration. I did initially, and the dimming levels weren’t correct. Running calibration afterward fixed it immediately and made the dimming smooth and accurate. You can also set custom brightness percentages if you want precise control.Build quality feels solid, and the design is clean. A standout feature is the subtle glowing ring when the light is off—it’s surprisingly useful in a dark room. If you don’t like it, the ring can be disabled in the device settings.The only downside is cosmetic: if you’re replacing a switch that uses a double faceplate, you’ll need to reuse your existing plate or buy a matching double to avoid mismatched covers.Bottom line: easy installation, reliable performance, and thoughtful features. Highly recommended.

So far so good! This product was extremely simple to install, and even easier to set up using the Tapo App. The dimmer buttons are very tactical and offer a solid click when pushed. The on/off button has a good spring-like action when pushed. The App also offers tons of automations and customizations. For example, between the hours or 11PM and 6AM, I limited the brightness to 25% so if I need to turn on the light in the middle of the night, I'm not blinded!

I replaced competitor switches d/t unreliable network connections that were on and off the network randomly. These have been refreshingly solid performers over 6 months plus after installation. Dimming aspect is stepwise as opposed to smooth dimming- perhaps because of the bulbs themselves. Back-wiring is a huge plus as opposed to my other units that had pigtails. Works very well with voice control.

Great functionality, once you install the cover it is very difficult to remove, will almost break, not well designed if you need to reposition it.

TP-Link Tapo Matter Smart Dimmer Switch – Voice Control with Siri, Alexa & Google AssistantThis is the primary dimmer switch running in my smart home lighting system.I currently have more than 50 TP-Link Tapo devices installed throughout my house, including switches, dimmers, outlets, and plugs. These dimmer switches are a core part of that setup and control many of the lighting routines across the home.The dimming performance has been excellent. They handle LED bulbs very well with smooth dimming and no flicker, which is something I’ve run into with other dimmers in the past.One of the big advantages is Matter support. Since these switches can operate locally, they respond quickly and continue functioning even if the internet connection is down.Reliability has also been very good. After more than a year of use, I’ve only had one switch that needed a full reboot and reset, which is impressive considering the number of devices running in the system.The Tapo ecosystem has been easy to manage as well. I run several other Tapo switches and outlets throughout the house, and they integrate seamlessly together. The system also works well alongside TP-Link Kasa devices, and everything can be managed through the same app.While I do use Alexa for voice control, I actually prefer using the routines within the native Tapo app. The automation options there are a bit more flexible and work very reliably.Overall these have been very stable and have become the backbone of my smart lighting system.

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.)

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.

Installation was very easy with the help of the included guide and some YouTube videos. Had no problem installing in a double gang box.Easy integration with HomeAssistant as well. It's now being controlled by the Tapo integration within HA and is able to turn on and off with my door sensors.Responsiveness is great as well. Dimming functionality works without a problem, even through HA integration.

Tp link adding matter support is great!

This is my first time with Tapo delay switch, it’s not working great with LED when brightness set to 2 LED keep flicking.

Has everything that I was looking for. Works with Apple HomeKit without any hub due to matter compatibility.

I had high expectations for this dimmer switch, especially because it uses Matter technology, which is supposed to be modern and reliable.However, even after professional installation, my dimmable spot lights keep flickering constantly when o use in first stage of the light intesity and works well when the intesity is high I dont know why.. This completely defeats the purpose of having a dimmer and creates a very unpleasant lighting experience.I made sure my lights are compatible (dimmable), so this should not be happening. Unfortunately, the switch seems unreliable or not properly designed to handle real-world setups.Very frustrating experience. I will have to remove and replace it.Not recommended if you want stable, flicker-free lighting.

It took a bit to figure out the classes of smart switches from TP-Link. The Matter feature is what I needed. Great product

Love the TP-Link stuff but this was my first Matter switch. Struggled a bit getting it set up as I'm stuck in bad habits after setting up as many Kasa switches I have, these are a little different.

It works great.

We all know the struggle of finding a dimmer that will dim LEDs without that annoying flicker - and here it is! Cheaper than a regular dimmer and the ability to link it to Google/Alexa is a game changer. Ive bought 6 so far and recommend them to all my friends, family, and clients. I set up 4 of them at my parents place to react to different commands through the Google Home like "it's TV Time" and "Night night". Super handy and super easy to set up! I love Tapo, though, honestly.

Works as advertised, it is hard wired to the wall, you must have basic wiring knowledge to install it. Lever nuts will not work, you must connect the wires to the conductors (screws)
