You need to have nut-monitor.service running. The command

  systemctl list-unit-files | grep nut should report

  nut-driver.service                         static
  nut-monitor.service                        enabled
  nut-server.service                         enabled

plus any "delayed UPS shutdown" service you might use.  nut-driver is started 
automatically by systemd whenever nut-server starts.

The command ps -elf | grep -E "nut|ups" should show

  1 S upsd      3096     1 ... /usr/lib/ups/driver/...
  1 S upsd      3100     1 ... /usr/sbin/upsd
  1 S root      3104     1 ... /usr/sbin/upsmon
  5 S upsd      3105  3104 ... /usr/sbin/upsmon
