I built a dashboard to monitor my PC's performance with a cheap ESP32 display, ESPHome, and Home Assistant
It's surprisingly useful, and you can show anything you want on the screen.
I recently picked up an ESP32-powered Cheap Yellow Display, otherwise known as a CYD. For about $20, you get an ESP32 hooked up to a screen, with an SD card slot and some exposed GPIO pins for your own additions. While ESPHome has some decent tools built in for creating a UI, it added support for the Light and Versatile Graphics Library a few months ago, otherwise known as LVGL. This is a graphics library filled with prebuilt widgets, and it looks a lot nicer than anything I could create in ESPHome.
