Actually, I think we are a bit further along than that. The details are a bit of a distraction for your current request, but in short, we got the development version of NUT (Git, after July 2014) to talk to a SMART500RT1U (Protocol 3005) with the tripplite_usb driver. We just haven't done all the usual polishing for a 2.7.3 release. Since we do continuous integration of the build process (just not hardware testing), we have snapshot *.tar.gz files that should be representative of the upcoming release.

The protocol specification for 3005 would be more of a confirmation of what some of the observed values actually mean.

I haven't really used RedHat products regularly since before they started the Fedora project, but from what I understand, it should still be possible to grab the SRPM for NUT, extract it to /usr/src, change the version number to 2.7.whatever, rebuild the binary RPMs, and reinstall.
