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.
I should look into ESPhome too, I think I could find some cool things to do with it, but for some reason I never did. Thanks for posting this, it looks cool. Are you getting the information from some API which also shows if the bus is late or is it a static time table?
Thanks! I get the information from the Entur integration in HA, which gets data from several of the public transport services in Norway. The information is live, and there's even an attribute for current delay.
