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.
Wouldn't happen to have a link to that board n screen combo you used would you?
This is the one I bought. I went with the "Chip" version, that has an integrated serial-chip https://www.aliexpress.com/item/32869729970.html
