Display Prometheus Graphs on Amazon Kindle

Intro

For more information see Matthew Petroff's original idea at https://mpetroff.net/2012/09/kindle-weather-display/

I use six Mijia Bluetooth temp/hum sensors in my setup. Some are flashed with pvvx firmware. I generate a new picture every few minutes via cron:

*/4 * * * * /home/pigpen/kindle/generate_kindle.sh > /dev/null 2>&1

The graphs show the changes over the last 3 hours. Arrows indicate quick changes in values.
