Review: Smart upgrade for home lighting! - I installed this 2‑pack of Tapo S505 smart light switches around my house and I’m really happy with how well they work. These switches let me control lights remotely via the Tapo app, or with voice commands using Alexa, Google Assistant, or Siri, which is super convenient when my hands are full. The Matter compatibility means they integrate smoothly with other smart home systems and work reliably even when the internet is down — local control is responsive and fast. The schedule and timer features are great for automating my lights, and setup with the app was straightforward (just make sure you have a neutral wire in the switch box). Overall these switches are a great value for making regular lights “smart”, and the 2‑pack gives you flexibility for multiple rooms. Perfect for anyone upgrading to a more connected home!
Review: Great switches that are easy to install, look great and have great dimming. - 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.

### ⭐⭐⭐⭐⭐ Works Great with Matter Connectivity, Easy to Install
*by S***V on January 21, 2026*

This smart light switch works great and has been very reliable so far. Installation was straightforward with clear guidance. The Matter connectivity works as expected, and setting up schedules is easy. One thing to note is that the physical position of the switch does not change when turning the light on or off—the small indicator light on the switch is the only way to tell its current state. Overall, a solid smart switch and I would recommend it.
