Fun. I used an e-ink display for something similar (just the weather forecast) and opted to use the onboard ESP-32. I try to stay away from Raspberry Pi for simple things because it's total overkill to have an entire operating system in there.

I did something similar for my daily calendar. I don't have a writeup of the actual device, but here's the firmware that generates the calendar image:

It's a really fun project, but I wish these Waveshare displays had more open firmware. I didn't really manage to get the ESP32 to talk to the display (or even to connect to it, as I don't have the right adapter), so I used their sample code with its weird API and I'm sending an image straight to the ESP32, rather than have the ESP32 pull it from an HTTP server, as I wanted.
