Restart service via Telegram bot

Configuration
1

I’m using Tor hidden services for GUI and SSH, with a Telegram bot as fallback for when Tor occasionally decides to stop working.

I would like to be able to restart Tor via the bot, so I have added this to my configuration.yaml:

shell_command:
  restart_tor: 'sudo systemctl restart tor'

When ran, I get this:

hassbian sudo[2437]: pam_unix(sudo:auth): conversation failed
hassbian sudo[2437]: pam_unix(sudo:auth): auth could not identify password for [homeassistant]
hassbian hass[2380]: 2019-01-12 23:58:15 ERROR (MainThread) [homeassistant.components.shell_command] Error running command: `systemctl restart tor`, return code: 1
hassbian hass[2380]: NoneType: None

I’m assuming user homeassistant does not have the necessary rights to do this?

Without sudo, the error is practically the same, just without the pam_unix lines.

Any ideas on how to achieve this?

EDIT:
Here’s the solution

Basically I added this line

%homeassistant ALL= NOPASSWD: /bin/systemctl restart tor

to

/etc/sudoers.d/020_homeassistant_hassbian-scripts

That file must have an empty line at the end!

I’m now trying to restart Home Assistant in the same manner. It works, but it throws return code -15. I’ve tried googling this, but everything I’ve found suggests there are no negative return codes…any idea what this return code might mean?

Have you solved this “return code: -15” issue?

Nope; I just ignored it since the restart worked anyway and I couldn’t find anything on “-15”.
