I got myself an ESP32 with an integrated e-ink display. This little project shows when the next bus to the city leaves, and the current time. I get the live bus data from Skyss through the Entur integration in Home Assistant. Might have to get a few more of these to tinker with.
This is awesome. Didn’t know there were ESP32 with integrated e-ink screens.
I still miss a cheap ESP32 device that can run on an18650 or two for a longer period.
