Can you use LVGL visual builders such as Eez Open in ESPHome? If so, it would make things so much easier than just trying to build an LVGL UI from code and rebuilding constantly to see changes/fixes.
I’ve just started looking into this myself this week. I’ll let you know if I come up with anything, but my esphome-fu is still fairly novice and I don’t know much about LVGL at all.
