On my jailbroken Kindle I wanted to display information about it (e.g. its IP address, battery level etc.)
There is a command on the Kindle, namely lipc-get-prop
that you can use to gather information about your device, e.g.:
lipc-get-prop -i com.lab126.powerd battLevel
Additionally, to find the information youโre looking for, you can leverage lipc-probe
like so
lipc-probe -a | grep -C 20 -e batt
This way you can discover what keys seem interesting for your use case.
Furthermore, you can use the built-in command to interact with the e-ink display named eips
