Success Avoiding Sleep While Plex Server is Streaming on Arch KDE-Plasma

Plex Media Server Desktops & Laptops

I finally have success preventing my computer from entering sleep/suspend while the Plex Media Server is streaming on Arch with KDE-Plasma.

I know absolutely nothing about shell scripts.

Within Plasma Energy Saving there is an option to run a script. I point it to a simple script to check if the port is open.

I borrowed the command heavily from collindelker.com/wp/2015/07/plex-linux-prevent-sleep/http://

Don’t forget to make the script executable.

Here it is:

          s=$(curl localhost:32400/status/sessions | sed -n "s/.*MediaContainer size=\"\(.*\)\".*/\1/p")
          if [ $s -gt 0 ]
          then
              echo "[$(date +"%Y.%m.%d-%T")] Number of streamers = $s Plex session active, cancel suspend" >> /home/[user]/plex_sleep_log
                exit 0
         fi
    
        if [ $s -eq 0 ]
        then
            echo "[$(date +"%Y.%m.%d-%T")] Number of streamers = $s Plex session -IN-active, going to sleep now   zzzzzzzz........" >> /home/[user]/plex_sleep_log
            qdbus org.kde.Solid.PowerManagement /org/freedesktop/PowerManagement Suspend
            exit 0
        fi

That’s it.
I’m sure there are more elegant solutions.
I’ve only tried this a couple of times so we’ll see how it works in the wild.

This method no longer works, the server never sleeps because it throws an error when executing this script.
Collin Delker proposed a solution at collindelker.com/2016/10/16/plex-linux-prevent-sleep-take2.html

I haven’t been able to make it work as of yet.

I’m using this command in the comments with a slight modification for ss -p in lieu of netstat -p and a ; was omitted before else.

ExecStart=/bin/sh -c "if [ 'ss -p | egrep -c STREAM.*CONNECTED.*Plex' -gt 0 ]; then exit 1; else exit 0; fi"

Also tried ss -p | grep "ESTAB" | grep -c "plex"', but still doesn’t prevent sleep.

systemctl status reports inactive (dead)

As hoffmajf noted, the original script doesn’t work anymore (because it requires a “X-Plex-Token” API token to call). I’ve put a full walkthrough of how I’ve gotten this working over here:

Hope this helps!
