[Nut-upsuser] Tripp-Lite BCPERS450 shutdown/restart problems
Thanks for your help.

This may sound like an apples-to-oranges comparison, but we did uncover an
issue with CyberPower UPSes where the delay values needed to be greater than or
equal to 60 (seconds), since they were being rounded down to integer numbers of
minutes internally:
What was the largest delay you tried?
I have now tried 200 seconds without any change. The offdelay setting
does appear in the status as ups.delay.shutdown, but seems to have no effect.
> ups.timer.reboot: 65535
> ups.timer.shutdown: 65535
>
I seem to remember that these values should change to e.g. -60 if you
set the delay to 60, and then they should begin counting down after
the shutdown command is sent. It has been a while since I messed with
that code, though.
No matter what settings I use, the UPS seems to turn off the load
immediately in response to the shutdown command. I have never seen
ups.timer.shutdown change from the value above. After shutting off the
load, ups.timer.reboot changes to 10, regardless of the setting of
driver.parameter.ondelay. It then counts down to 0 and turns the load
back on.
What log messages do you get with "/lib/nut/usbhid-ups -DD -a
bcpers450 -k"?
See below.
For future reference, was this UPS manufactured recently?
I have just purchased it new, so presumably yes.

[Nut-upsuser] Tripp-Lite BCPERS450 shutdown/restart problems
Any more thoughts about how I might get this UPS working? I guess I
could try using the software from Tripp-Lite, but it is intended for
ancient versions of Fedora and OpenSUSE, whereas I'm running Ubuntu
16.04. It would be much nicer to use Nut, but I don't know how to
proceed.
Thanks.

This at least seems to explain the 10-second delay. Here's what I think is going on: NUT looks up the "shutdown.return" ("Turn off the load and return when power is back") command, and finds nothing that matches your UPS. Then it tries "load.on.delay" - same problem. It then finds the path for "shutdown.reboot", which is most likely mapped to this line: https://github.com/networkupstools/nut/blob/v2.7.2/drivers/tripplite-hid.c#L394 (IIRC it's the first match, otherwise it would be https://github.com/networkupstools/nut/blob/v2.7.2/drivers/tripplite-hid.c#L397 ) That sends a value of 10 (likely corresponding to the 10-second delay) to UPS.OutletSystem.Outlet.DelayBeforeReboot The fact that there is not a "UPS.OutletSystem.Outlet.DelayBeforeStartup" or "UPS.OutletSystem.Outlet.TLDelayBeforeStartup" in the debug output for your UPS means that the "wait for power" functionality is probably hidden behind something else, possibly another vendor-specific item (see, for instance, "UPS.OutletSystem.Outlet.ffff00bc" and the other ffff* names after "*.DelayBeforeShutdown"). To be honest, if you can set up the Tripp-Lite software somewhere temporarily (possibly an older laptop, or maybe even in a VM - though VMs have their own issues), that might be the quickest way to get the behavior you are looking for. You could set absurdly large shutdown timers, and fire up usbhid-ups in debug mode to watch the counters. I think that would be safer than trying to set various vendor-specific items to random values.

[Nut-upsuser] Tripp-Lite BCPERS450 shutdown/restart problems
Thanks again for your help, Charles. I was able to install the Tripp
Lite software on my Ubuntu machine, and it sort of works. It does
something which continually changes the USB device ID of the UPS, and
prints voluminous error messages in the log. However, one of the things
that it can do is to schedule a UPS shutdown, which Nut does not know
how to do.
So I monitored the USB port with wireshark (an interesting endeavor
since I didn't start out with any knowledge of USB protocols). But I
have managed to discover that when I ask Tripp Lite's poweralert
software to schedule a UPS shutdown, it does it by using the SET_REPORT
function of the USB HID protocol with ReportType "Feature", ReportID
21
(0x15), and 3 bytes of data which are 0x15 followed by the number of
seconds to wait before shutting down in two bytes, LSB first.
Below I include wireshark packet dissections for two such commands. The
difference is in the "data fragment". In the first case it is 150500,
representing a shutdown in 5 seconds, and the second 153701,
representing a shutdown in 311 = 0x0137 seconds.
Is this helpful?
