All the videos I made on displays relied on a 3rd party HMI editor. They were nice to create, but how about long-term supportability? Will the programs still be available? Will the libraries be compatible? Some generate C source code and need to be tweaked and compiled - this is a barrier for many of you. And the SquareLine Studio has a lot of limitations unless you get an expensive license.
So, I always thought that the best way to make displays for Home Assistant would be in ESPHome.
However, the current primitive drawing functions will only allow for a very basic HMI.
But this is changing now - the popular LVGL graphics library is coming to ESPHome, with a large library of useful widgets!
I got a nice ESP32 5" display from Elecrow, that supports LVGL - so let's take it for the ride.
