If you didn't have the configuration setup as required, you could still
spawn a second process to kill and restart your process as well, this
works too, but Michael's suggestion is probably much cleaner, and in all
likelihood, is probably the preferred method, but I know folks struggle
with the whole system process configuration issue, so some go the other
route just for simplicity sake.

I would like my service application to restart itself once per 24 hours, but

Just exit ?
If you configured systemd to start your app correctly it will restart it.
Is it as simple as that? Here is my service file:
[Unit]
Description=SSRemote Server
Wants=network.target
After=syslog.target network-online.target
[Service]
Type=simple
ExecStart=/agi/ssremote/bin/SSRemoteServerLx
Restart=always #<== This
RestartSec=10 #<== And this
KillMode=process
User=pi
[Install]
WantedBy=multi-user.target
Do these 2 marked lines mean that if the service application just exits (with no
exit code) systemd will restart it after 10 seconds?
Yes.
And:
Right now I am running it as user pi as shown above, is there some reason I
should run it as root instead?
Running as root is not recommended. You can do it, but I would not.
Thanks Michael, much obliged!
Makes things so much simpler. Just exit at the appropriate time. :-)
