In this video, I walk you through how to install the Aqara Touchscreen Switch S100 and what makes it different from a “normal” smart switch. I cover the basics of getting it in the wall and then focus on the real reason you’d buy it: the built-in touchscreen. The S100 isn’t just for turning lights on and off—I use it as a wall control point where you can manage scenes, devices, and automations directly from the switch. I also break down the connectivity side, because that’s a big part of the S100 story. With Matter support plus Thread, Wi‑Fi, and Bluetooth, it’s designed to fit into a mixed smart home setup without making you feel locked into a single ecosystem. On top of that, I call out a few practical features that can actually change how you run your home day-to-day: energy monitoring, customizable controls, and presence detection so automations can trigger automatically. If you want a cleaner, more “hub-like” wall control that helps your home feel responsive, the S100 is built for that.
