WOL turn_off works for Windows but not Linux

Configuration
1

Hi all

Apologies if this has been covered, I did search for it but couldn’t find this specific issue anywhere.

I have set up WOL for 2 PC’s. One is a Windows PC and one is Ubuntu. Both wake up fine, but only the Windows PC will turn off. The strange thing is I have set both up with a small bash script each, and the Ubuntu PC will turn off if I run the script from the command line. It just won’t turn off via the switch in HA.

Here is the script I am calling:

ssh [email protected] sudo shutdown -h now

And here it is in my configuration.yaml file:

shell_command:
  pcoff: /home/pi/scripts/pcoff.sh
  ubuntuoff: /home/pi/scripts/ubuntuoff.sh

…

switch:
  - platform: wake_on_lan
    name: "Wake PC"
    mac_address: "AA-BB-CC-DD-EE-FF"
    host: "192.168.0.79"
    turn_off:
      service: shell_command.pcoff
  - platform: wake_on_lan
    name: "Wake Ubuntu"
    mac_address: "AA-BB-CC-DD-EE-FG"
    host: "192.168.0.78"
    turn_off:
      service: shell_command.ubuntuoff

Similarly if I call the service from HA Developer Tools it ignores me, whereas calling the shell_command.pcoff works just fine. Clearly there’s a problem with HA calling the script since the script works from the command line, but when I switched the logger on and ran a tail -f command on the log file it reports the script as running OK:

So now I’m a bit lost! Any ideas gratefully received.
