Thanks Jim... That at least fills in one of the blanks- wasn't clear
to me if the driver was built into nutd or a separate process. As you
guessed, OpnSense is based on FreeBSD. I was able to track down the
ups driver and try to start it and it is erroring out:
$ upsdrvctl start ups
Network UPS Tools upsdrvctl - UPS driver controller 2.8.3 release
Network UPS Tools 2.8.3 release - Generic HID driver 0.62
USB communication driver (libusb 1.0) 0.50
libusb1: Could not open any HID devices: no USB buses (or devices) found
No matching HID UPS found
Driver failed to start (exit status=1)
Confused by this since I'm running the above command as root and
nut-scanner -U works fine?

Note that on Linux with systemd and NUT 2.8.x (and a nut-driver-enumerator service/daemon), it may be wrapped into a nut-service at upsname.service instance, similarly on Solaris/illumos with SMF. You seem to be running a variant of BSD thiugh, so maybe lack some init script for NUT drivers? Also note that typically such scripts call `upsdrvctl` and let it handle your population of the devices.
