What does the system log show as the Linux box shuts down? I would expect to see something like: ... Jan 26 08:00:37 maria systemd[1]: Reached target Shutdown.

Jan 26 08:00:39 maria systemd-journald[303]: Journal stopped which shows that this is a controlled systemd shutdown and not a crash. It also shows that a "delayed UPS shutdown" has been sent to the UPS, so that it will turn off it's outlet sockets _after_ the Linux box has shut down, thus ensuring an automatic restart when power returns.
