For the 1000, do the values match this page?


It doesn't look like we have an entry for a C1500 yet. Would you care to submit the output of upsc, upsrw and upscmd -l?

The driver reports values with standard USB HID names. It is possible that your UPS reports these using different names, or does not expose them at all over the standard USB HID PDC interface. Here's a quick APC protocol guide based on model numbers: http://lists.alioth.debian.org/pipermail/nut-upsdev/2014-July/006769.html

If you want to check for any hidden variables, stop the driver, and run "/lib/nut/usbhid-ups -a name -DDD 2>&1 | tee /tmp/APC_Smart-UPS-C1500.log" as root for a few minutes (it will loop endlessly; press ^C to stop). Please gzip the log before attaching it and sending back to the list.
