Nut upsuser - Sep 2020 - UPS recommendation for NUT and power-on-delay support

But runs normally if started.  On a rpi4 running an uptodate raspbian 
buster, how do I set it to auto start at boot time?

Thanks.

Cheers, Gene Heskett

Hello Gene, By "auto start" I assume you mean the automatic power on
of a box
when wall power returns after a power failure. For this to work, two things are 
needed:

  1. The UPS power outlets have been turned off.

  2. The box's BIOS has been set to "power up on AC return".  (The
words may
change, it depends on the BIOS.)

The problem may be that the box is turned off without a command to the UPS to 
later turn off the power outlets.  When the power outlets are turned off, you 
should hear the "clunk" of the relays.

Roger, I don't have any experience with the Raspberry Pi 4, but previous RPi
models would just boot as soon as power is applied, so I'm guessing this is
more of a problem starting NUT at boot.

Gene, assuming this is a "standalone" setup (upsd, driver, and upsmon
on the same system). If so, I'd recommend using "LISTEN 127.0.0.1"
if you don't need network access (e.g. upsc or other monitoring software on
another box), or "LISTEN 0.0.0.0" to listen on all local network
interfaces.

If the LISTEN line is't the culprit, I'd recommend posting the output of
"systemctl status nut-server.service" after boot to see why it
didn't start (or more likely, stay running after starting).

I have a standby that starts in about 5 seconds, so theoretically, any 
shut downs, which shouldn't happen unless the generac blows up, won't 
happen.  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kernel and its libs, which have been replaced by a locally built 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.

You might also be able to leverage wake-on-lan here, since much modern
hardware is never really fully "off" as long as it is powered.

Dear All,

Could you please recommend me a UPS with 100% support of the ondelay
parameter and NUT compatibility?

850 or 1000 VA

I have the EATON 5E850iUSBDIN UPS and it does not support this parameter so
I would like to buy another UPS that for sure will support it.

Thank you,
Bart

Hi,

I'd also be interested in hearing other people's experiences regarding
this. It would be even better if there'd be the option to power on
only when the battery has been charged to 50% for instance, but I'm
guessing this option is reserved for professional UPSes in the 1k or
higher price range, so I'm not holding my breath.

Currently, I'm running a Legrand KEOR SP 600 which has the OnDelay
option in its software and it seems to work as advertised (I remember
testing witn OnDelay = 60 sec and it worked).

The issue is that their software (UPS communicator v1.34 [1]) is quite
old, so I was only able to get it to run on an old 32bit Debian7 VM.
Yup, in 2020, the software controlling the UPS only runs on 32bit
OSes. So the UPS is controlled by this VM (which I've configured with
USB passthrough) and, when the power goes out, a script on the VM
SSHes into the other devices in the network and shuts them down. Quite
the convoluted setup... Unfortunately, I did not have time to test the
UPS with NUT. Maybe sometime in the future.

Can you tell from this output? If not, what should I be looking for to answer
your question?

I have an Eaton Ellipse Eco 1600 bought in 2016 which has a delayed start 
feature.  If wall power returns quickly, the UPS will wait this time to restart 
the outlets.  But now that manufacturers seem to be silently removing this 
feature from their UPS's I don't know if the current versions support 
ups.delay.start

If I understand the question correctly:

> ups.delay.start: 30
Perhaps these commands also do something similar, but my Ellipse 1600 does not 
have them:

The Eaton 5P 850G and the 5P 1000 have the option "Auto start delay":

  Load segments - Auto start delay [No Delay] [1 s] [2 s]…[65354 s]
  The connected load is powered after the specified delay.
  Defaults: Group 1: 3 s  Group 2: 6 s

Maybe it's the difference between the "E" equipment and the
"P" stuff. See
https://www.eaton.com/content/dam/eaton/products/backup-power-ups-surge-it-power-distribution/backup-power-ups/eaton-5p-ups/eaton-5p-ups-installation-user-manual.pdf

The noise level is given as < 40 dBA so maybe it has a fan running
permanently.
Eaton's Automatic Voltage Regulation can be noisy.
