Guten Tag, ich versuche seit 2 Tagen mein E-paper von Waveshare zum laufen zu bekommen, ich habe das ganze nach dieser Anleitung angelötet.
Dort ist ein älteres E-paper HAT zu sehen, bei meinem gibt es noch den Ausgang PWR dazu, den habe ich laut einem anderen Forum auf 3V mit angelötet. Nun zeigt mir das Display was an, aber noch mit fehlern.
Meine ESPHome Config in Home Assistant sieht wie folgt aus:

Hat hier jemand eine Idee was ich übersehen habe? Was ich falsch gemacht habe? Wäre über jede Hilfe dankbar. Danke. Schönen Sonntag euch allen
