value, which should be the output current from the UPS.
However, the value reported for "UPS.PowerStatus.Output.Current" is
not the output from the UPS terminals to the load, but is the
current into the LTC3780 buck-boost converter on the output. The
evidence for this is that with a known constant load, the current
reported is dependent on whether we are using battery voltage or
input voltage, and varies as one would expect if it were reporting
the current supplied to the LTC3780.

[PATCH 0/3] OpenUPS updates
Hi,
I've been checking out NUT with an OpenUPS board over the last couple
of weekends, and have noticed that it doesn't seem to report sensible
values. This lead me to investigate usbhid-ups and delve into various
issues.
As mentioned in a github issue, one of the problems is with the report
descriptor - dumping this from the usbhid-ups debug output and picking
through it reveals that
