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.

https://esphome.io has documentation on all the components, how to draw sth on a display and a few example projects under "Cookbook".

Thanks. I just got a couple of cheap chinese ESP32s and was going to start with some Arduino IDE programming, but I'll have a look at esphome too

I can recommend PlatformIO or Arduino. Or MicroPython, CircuitPython ... if you're into that or the learning curve for C proves to be too steep. ESPhome is really great for connecting to HomeAssistant or doing some standard IoT stuff and getting results without too much coding.

The ESP32 are really versatile and a good choice to get your fingers dirty with (in my opinion).

"something": how to draw something on the display. Sorry, I'm a bit lazy when typing on my phone.

In the beginning I struggled with getting the display to work, until I found this forum post https://community.home-assistant.io/t/using-ttgo-epaper-display-with-esphome/168877/27 Aside from that, I mostly used the ESPHome website that hendrik in the other comment mentioned. It took a lot of trial and error, since I didn't know any YAML beforehand.
