hey, my openhabian crashed and is no longer running, of course i didn’t make a backup because i’m stupid 
on my windows pc i can still read the sd card, is there a way to copy the settings (items routien etc) and then reinstall openhabian on a new sd card and then copy the items etc over?
or do i have to do it all over again 
If you can read the userdata folder, you will find your old configs.
This is just the boot partition. You will need a linuxreader for Windows to see the rest….
No, please read the docs for folder structure.
There´s currently another thread, which might help in finding the right directories: Backup Openhabian
