What model of UPS is it? Many of the newer models use a protocol called
"Microlink" (aka MODBUS over USB) . APC (and their parent Schneider
Electric) have been quite secretive about this protocol, unlike the
older protocol where they provided nice interface specifications.

So, firstly, make sure you're using a sufficently new version of APCUPSd
(3.14.13 or newer). Secondly, check that you're using the modbus
protocol: http://www.apcupsd.org/manual/manual.html#modbus-driver
Finally, if that doesn't help, then it may simply be that the UPS isn't
reporting the required information.
