Thank you, this is much appreciated. I don't actively work on this project but will try to integrate it next time I do (could be a while). At very least it's here for others to discover :)

At least is a starting point for someone like me that bought that crap and do not want to throw it in the garbage After finishing my idea to integrate those display in some of my wall switches ( using yours as a baseline) I realized that it is better to use a cheap android phone and use fully kiosk browser with home assistant app Easier to customize, way better options like photoframe and music in each device

Agreed - I went through quite a few devices starting with the Sunton 2.8". Most of the devices I've had I would never purchase again, but they were sure exciting to play with initially.

The Guition devices supported by this project are the ones I like the most (by far) and they were only around $20-25 CAD, however they still have the odd missed/wrong touch which bothers me. They have very nice bright screens with good resolution and viewing angles (I think they are IPS), and they are capacitive touch as well.

I use them around the house in some doorways and on our nightstands, Also one on my coffee table for all the times I can't find the TV remote and want to change volume or pause, or adjust lights.

Hopefully newer better devices keep coming along, and hopefully ESPHome improves more and more at the same time. It needs to be easier to work with LVGL and YAML is also very limiting.
