Yeah, I figured there would be software for the purpose which I didn't
specifically know about.

At a glance, however, both of those look like they still require a USB
connection... and my (APC) UPS doesn't seem to have a USB port. It does
have a network port, so I imagine that maybe I could get things working
with a network cable to the house switch, but that seems like a clunky
and unwieldy sort of solution at best.
