Elecrow CrowPanel 7" with ESPHome

ESPHome
1

I have V3 of the above device and like others are struggling to get a stable display that does not flicker or blank the screen every few minutes.

Just wanted to see if anyone else has had any luck as its a great device??

I am aware that others have tried but given up when using an earlier version and of course I have tried all code that I found on the web including from the manufacturer which is also not stable.

I also have the 5" version and this works perfectly with ESPHome & LVGL.

I believe the issue is due to support for different display drivers, but this is beyond my technical ability.

Thanks for any help… currently its a great bookend!

It seems to be compatible with openhasp, so give that a go.

In fact their advertising even says so. Happy days

Thanks for the hint… I know nothing about openhasp, but perhaps this is something I can look at if all else fails!!
Cheers

Curious if this helps

This config works well. I am underwhelmed by the display though - it has a very poor viewing angle and the pixels are not quite square so the aspect ratio is wrong - images are slightly squashed vertically. The Waveshare 7" display is much nicer.
