I've been running all sorts of little things on Rasbperry Pis for years but I recently bought an e-ink display without really having a plan for it.
I don't have my mobile phone upstairs overnight and I thought it would be useful to have the weather for the day in my bedroom in the morning so I know what to wear. An e-ink display is great for the bedroom as it doesn't give off any light.
I've been aware of Balena Cloud since it was still called Resin but I'd never deployed anything with it beyond a few little experiements. I decided this would be a good first proper use.
You can see the code and setup instructions on Github.
