I bought a 7.5 e-ink screen from Waveshare here and got it to work via an Arduino and on a Wemos Lolin32 but seem completely unable to get it to work on ESPHome…
ESPHome version is v2022.2.6, the ID on the label connect of the screen is WFT0583CZ61 and hooked it up according to the config from the source provided by Waveshare itself. It does not match 1 to 1 with the image on the site I bought it from, connector seems different.
I’ve tried different ESP32 boards, bunch of different wiring, all 7.5 inch models… I have no clue what else I can do.

Using the same pins as on the working Arduino framework code;
