Introduction
Home automation projects usually look impressive in videos, but when you try building one yourself, things quickly become messy — loose wires, random modules on the desk, and half-finished enclosures.
In this tutorial, we build a clean, touch-based controller using the ESP32 S3 Box 3 that can control four lights locally, without any app or cloud dependency. This project is beginner-friendly, works offline, and is perfect as a practical home automation demo or hackathon prototype.
The Idea
Most homes still rely on traditional mechanical switchboards. They work fine, but they don’t provide visual feedback or flexibility for future automation.
Instead of replacing every switch with expensive smart switches, this project replaces the control logic behind the switchboard with a single touchscreen panel.
The goal is simple: big buttons, clear ON/OFF feedback, instant response, and no internet dependency.

I’ve also documented the complete build process in a step-by-step video, including wiring, UI design, and live testing.
If you prefer learning by watching, this will help you follow along and build the same project easily.
