Help to find the error! I can not display the battery charge on the site map!

исправил, но не заработало. в лог теперь вот такая ошибка.

Yep, as stated before, it does not suffice to write sudo in front of a command.
GNU/Linux sudo is used to extend permissions to root, so sudo will ask for a password every time it’s executed. The user openhab (this is the one that openHAB is using) needs permission to use the sudo command without typing a password.
NOT openhabian, the user is openhab!
User openhabian is a common user to get command shell access.
User openhab is a user without regular shell access. this user is used only to run openHAB.
and a bad idea, maybe you could allow openhab to access the bus?
