reMarkable paper tablet – “suspended” screen customization Part 3

Today I modified a small script now generating PNGs with the date and a random comic of the well known site xkcd.com. (Sometimes the comic is to big.. I’ll fix that soon)

Another script on the rM controlled by a systemd timer gets a new suspended.png every hour if the rM is online.

Just put the following scripts on the rM via ssh and start the timer!

/etc/systemd/system/pocp.service
 [Unit]
 Description=suspendchanger

 [Service]
 ExecStart=/usr/share/remarkable/pocp.sh
 WorkingDirectory=/usr/share/remarkable

/etc/systemd/system/pocp.timer
 [Unit]
 Description=suspendchanger

 [Timer]
 OnBootSec=1m
 OnUnitInactiveSec=1h

 [Install]
 WantedBy=multi-user.target

/usr/share/remarkable/pocp.sh
 #!/bin/sh
 if ping -q -c 1 -W 1 abcxyz.de >/dev/null; then
    echo "The network is up"
    wget -O "suspended.png" http://abcxyz.de/rm/png_kxcd.php?c=white
 else
    echo "The network is down"
 fi

Now you have to enable the timer.

remarkable: ~/ systemctl enable pocp.timer

You could also start it right away if you want.

remarkable: ~/ systemctl start pocp.timer 

To check if it is running you can call

remarkable: ~/ systemctl list-timers

The easy steps above should result in this..
