I have my old Kindle displaying the weather through the built-in browser, using this code:
https://github.com/matopeto/kindle-weather-dashboard
If you want to display something more, you could just self-host a page.
See also https://inkplate.io/, which is a Wi-Fi-enabled display made from recycled Kindles (GitHub repo is here: https://github.com/e-radionicacom/Inkplate-6-hardware)
Nice. I'm doing something similar with a BOOX Mira 13.3" touch screen, Raspberry Pi Zero and a Gioui app for the user interface.
I'm building an expedition vehicle on the back of a Mercedes Actros 6x6 semi-truck. I'm using M5Stack ESP32 devices (flashed with esphome) to read all the sensors and control everything. I'm using a MQTT server as the messaging hub: the UI will read/write from that, and the ESP32 devices will subscribe to that for controls.
Here's my notes on getting the e-ink screen working full-screen with a Gioui app (without a desktop linux environment): https://github.com/dave/iot/tree/main/ui
It would be great to find a cheaper alternative (the BOOX Mira is $800 ouch!)
