hello,
I would need to know if in dietpi (debian) there is same option to schedule the hibernation command (or script) of our raspi 1 A + and also schedule a wake-up at a certain time / day
Regards 
Hi
In general SBCs did not support any hibernate function.
https://manpages.debian.org/buster/hibernate/hibernate.8.en.html
could you add this command?
or does the hardware of the raspi not allow it?
Maybe I was not clear enough, Raspberry Pi did not support any hibernate functionality.
