PW4 keep battery at 50% in long-term usage

Eicca · 01-31-2021, 09:05 AM

Hello,
I set up a kindle PW4 as status display for my FHEM-Server. Known from my Voyage I searched in filesystem for files like "allow_charging"/"charging" to alternating de-/activate charging to keep at 50% for protection of the battery. But all files I have found on PW4 are read-only and only GIVE the state.
Have anyone figured out a way to do this?

I tried to do the same in my Paperwhite 3 but it seems it's not possible.
Edit: Where are the allow charging etc. files located?
