It's based on the work found here:
See the original readme file.
I've modified those scripts to work on my Kindle 3 Keyboard.
I use it to fetch the image that shows my home dashboard. See this project:
https://github.com/bukowskiadam/kindle-page
Idea is to wake up Kindle every X minutes based on the schedule to fetch the file.
It's the biggest difference between other implementations you can easily find on the internet. Most of them disable the Kindle sleep and use cron to update the image.
Anyway, it's valuable to read how other people do it:
- https://github.com/mpetroff/kindle-weather-display (the same author as the base for those scripts)
- https://github.com/shatteredhaven/KindleWeatherDisplay
- https://github.com/dennisreimann/kindle-display
With those scripts, I get a pretty decent battery life and Kindle can work on a battery for a long time.

Important
Because my Kindle is so old that curl does not support recent TLS/SSL I had problems with downloading the file from Vercel. To fix that I cross-compiled a little program with golang and copied the binary here.
