I came across this idea here on Hacker News a while ago – a small weather display using an ESP32 and an e-ink screen to show a daily weather landscape. I loved it and shared the idea with a friend of mine. He went all in and rebuilt the whole thing in Rust – from the image rendering server to the embedded code on the ESP32.

It's a clean, minimal two-part project:

A Rust server fetches weather data from MET Norway and renders it as a landscape image.

An ESP32 downloads and displays the image on a 2.9" e-ink screen.

Here’s the repo: https://github.com/martinohmann/weather-landscape Would love to hear what you think!

How does it loop, if at all? Does it just restart at the end after it falls out of `main()`?

This is definitely something I'd like to try. Gotta figure out where to run the server... maybe a good time to figure out how to do custom Home Assistant add-ons.

How long do those batteries last you? Even with the deep sleep, I imagine doing the WiFi handshake every time is going to be expensive.
