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.php 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..
