well that all programming just went over my head, I’ve never flashed boards like this before, never played with Rpi’s or Arduino’s etc. (unless you have detailed instruction/pictures for windows).
I do have the latest unit, bought it in Dec ’19. I thought it was only the wifi chip, didn’t realize that was the main processor as well.
Guess i’ll just leave it alone and put up with poor wifi reception, or re-run all the wiring and shift it some where else away from their shed..
