I’ve been diving into the world of smart displays lately, and I have to say, the GUITION 4" 480x480 ESP32-S3-4848S040 Smart Display with LVGL has been a game-changer for me! 
This little gem checks all the boxes: a fast CPU, ample memory, a sleek design, and the ability to mount it like a wall switch. Plus, it comes with a 120v relay included, which is a huge plus for my projects.
I initially tested this display with the openHASP project, and while it worked, it felt limiting. That’s when I discovered the flexibility of ESPhome. The possibilities are endless—imagine building an entire automation system on this screen without needing Home Assistant or any other platform! For now, I’ve kept it simple with a light switch, but the potential for multi-page panels is huge.
One feature I absolutely love is the flexible grid layout for buttons. Instead of manually locating each button with pixel-perfect precision, the buttons automatically adjust and fill the space. This makes creating a modular system for button panels and info displays a breeze. You can even add custom buttons to control things in Home Assistant with just a few lines of code. Check out my GitHub repo for more details: GitHub - agillis/esphome-modular-lvgl-buttons.
The journey with this display has been nothing short of exciting. It’s not just a tool; it’s a canvas for creativity. Whether you’re a seasoned pro or just dipping your toes into the world of smart displays, this device is definitely worth exploring. Happy tinkering!
