I'm desperate about installing with esphome this Electraw Crowpanel :face_with_bags_under_eyes: :face_with_thermometer:

https://www.elecrow.com/wiki/CrowPanel_2.1inch-HMI_ESP32_Rotary_Display_480_IPS_Round_Touch_Knob_Screen.html

24h with Gemini and Chat and ..nothing wifi ok but no display. dozens of versions flashed and always 'black' or various backgrounds colors with vertical thin (about 1cm central area)

every try is game over

Did you try the Elecrow esphome example?

3

As @Karosm says have a look at their examples on GitHub

AI isn’t always great for HA/Esphome, always best to check official docs first.

4

looks like the ‘lessons’ on github were used as example for AI
but since then some good progression have been made .
the issue now is about external component that seems not to be compatible anymore with current ESPHOME (touchscreen)

6

Looks like there may be a native component, although it is for the 816 it does say it should work with 826.
