I'm using this val for my 3-color e-ink display run by a Raspberry Pi Zero W. The Pi runs a cron job that tell's it to fetch this url twice a day and render it to the display. Works like a charm.

Right now I'm not displaying much but I'm going to keep iterating on what type of information I want to display.

I'll post more info on my set up here later if you want to try something similar. But I assume this workflow could be used for lot's of different projects that don't have a ton of compute or where you don't want to learn how to actually draw things to a screen like all the e-ink display libraries.
