In today’s video, we’re building a touchscreen smart desk controller from scratch using a Nextion display, an ESP32, and ESPHome. You’ll see the full process step-by-step: ✅ Designing the UI in the Nextion Editor ✅ Uploading the .TFT file using an FT232 USB-to-Serial adapter ✅ Wiring everything together ✅ Writing the ESPHome code ✅ Flashing the ESP32 ✅ Live demo with desk & light controls — all smart-home integrated! By the end, you’ll have a working touchscreen controller that can control your sit/stand desk, lights, and other Home Assistant devices. Perfect for smart office setups, automations, and DIY lovers! 🙏 Huge thanks to PCBWay for sponsoring this video! Want to make your own custom PCBs or 3D printed enclosures for projects like this?
