Waveshare 1.54 (B) flashing and showing pixels all over the display

I’m using a Waveshare 1.54 (B) e-Paper Module with an ESP32 in ESPHOME.
I tried a lot of settings (see below my script) without any success. The display flickers all the time with pixels all over the whole display - see photo.

I tried it now with an e-Paper ESP32 Driver Board. Some issues, as before. The display is unusable due to the flickering and pixels all over.

Hello, I’ve got the same epaper (1.54 v2, B/W and red).
I finally managed to get it work perfectly.

From your original code, you have to do 2 modifications :

  • replace your model by 1.54inv2-b
  • delete the full_update_every command. Not supported by this model. It will not compile your project.

Let us know if it works now.
