I wonder if a build vs libusb-1.0 (compared to 0.1 for older NUT packages) had to do with it, or some other changes? Maybe some mayhem with LogMin/LogMax correction, or getting this UPS interpreted as a 3-phase?..

There was recently a report about CPS HID not reporting a voltage item where older NUT does still.

FWIW, linking to #1973 and #439 as possibly related issues (although not in CPS HID).

I recently started using nut with a Legrand Keor SP 800 and noticed that some reported values are wrong as well (as shown by upsc):
