I've been setting up a tiny tiny rss installation on my Raspberry Pi. I have more or less everything done, being the last step creating, enabling and launching the systemd process, as its written here.

My problem here is that I'm not really sure if the systemd process is running as intended or if I'm missing something here. My (basic) idea is "each 5 minutes, update the feeds", to be refined to a better schedule (i.e. don't update feeds when I'm usually asleep), but it seems the process either is not running or only runs when I click on the reader.

Doing systemctl list-unit-files | grep enabled (or with the grep enabled part) shows the process as running but, at random intervals, the web interfaces for tt-rss is telling me that the daemon is not updating stuff.

I'm guessing I will need to set up a cron task (as the updating feeds entry talks about, although it points to a different case of use) to update the feeds periodically, but I feel I'm missing something here.
