Its a 650WA cyberpower, running an rpi4 and its mesa based interface. all of which is running on a 5 volt 5 amp supply, max 30 watts drain IOW.
All I really want is the -wall broadcast from nut telling me its on standby power, and back on wall power 5 or 6 seconds later. But on a reboot, I have to start nut manually. So what I want to know is what to do, in which rc#.d to start nut automatically at reboot time. Its running on the raspbian clone of buster, all uptodate except the kernel and its libs, which have been replaced by a locally built preempt-rt kernel and protected from apt upgrades which would destroy its real time performance. The ups is working great, all I want is nut running and tracking the failures. Local power hasn't historically been as dependable as I'd like, and my installing a 20kw standby was in self defense since the missus has COPD and a long power failure killing her oxygen generator might have put a ~30~ on her story. She is now in a rest home till whenever? telinit says its obsolete, see systemd and systemctl. And I'm green yet at that stuff. Thanks.
