Theoretically, this should be the same as running the command "upscmd bcpers at localhost -u <upsd.user> load.off.delay <delay>".

I still haven't had a good chunk of time to walk through the shutdown code (the part that handles "usbhid-ups ... -k"), but in the mean time, would you be interested in setting things up to rebuild the driver? (The next week is looking pretty ridiculous for me, so I don't anticipate being able to dust off my .deb build tree soon.)

My thought is that you can rebuild NUT with the same configuration options as the .debs, and the usbhid-ups driver should just drop in. The instructions are almost the same for Ubuntu as for Debian:

http://lists.alioth.debian.org/pipermail/nut-upsdev/2017-October/007343.html (omit the "git checkout" line; although we have a new-and-improved libusb branch, I think it's an unnecessary delta for your situation.)
