So I followed this youtube video on setting up RTL-433 service on a Ubuntu server. Problem is, it seems to keep failing after a while. Sometimes doing a systemctl start service doesn’t work and I will have to reboot the system and then it will work. It will work for a while and later in the day it will suddenly stop. Sometimes I can do a systemctl start, but sometimes not.

Anyone know how I can have this service constantly up and running, and restart if it fails?

    To have it automatically restart on failure, you can add the following to your systemd unit:

    [Service]
Restart=on-failure
RestartSec=5s

    See this blog post for more information.

    But to find the root cause of why it’s failing, you can run systemctl status <service> when it fails to get the most recent logs and hopefully an error as to why it failed.

      Still relatively beginner, but wouldn’t ‘journalctl -u nameofservice.service’ also give you in depth logs over a longer period of time?

        Adding to this, journalctl -fu service will jump to the bottom of the log and effectively tail -F the log so any new output will be appended to your terminal

          I second journalctl -f -u SERVICE_NAME.service it’s great and just works well. The .service isn’t required, but it’s a good habit to get into since systemd also has mounts and timers.
