iirc I ditched puppet as the quality was just not up to what we need for this display. Probably great for full resolution, colour displays, but really not ePaper friendly.
I wish I could tell you what I did beyond that. I basically smashed various pieces of the tutorial at it until I got something useful on the screen, then went and read all sorts of other docs for rendering content and drawing lines and such. I ended up with 3 cycling pages that show my air quality levels across the top of all three, and then the lower 9/10ths of the screen cycle through my plant monitors to display their stats/alerts. I’ve got more plant monitors than I can fit in three pages now though, so I’ve got to go back to square one and figure out how to only render the ones with a “problem”.
