Well, the problem is with the UPS firmware itself, and it does prevent
use of the driver. If the driver thinks the UPS is "off", it will not
notice it if is on-battery or not.

I may provide a workaround, but you need to run a little test: with
the UPS powering something other than the computer (a lightbulb, for
example), tell the UPS to power off the load by sending it an instant
command:

    upscmd -u <nut_admin_user> -p <nut_admin_password> <your_ups> load.off

Then, run "upsc <your_ups>" to see the status. The status will either
remain "OFF" or switch to something else ("OL"). Either way, I'll know
what's needed, if an option to interpret the "OFF" bit the other way
around, or just ignore it.
