runtime! :/
I'm avoiding Eaton/Powerware because the lack of usbhid support, the
bcmxcp driver doesn't report much, but I have heard that someone is
working on it. Also a PW5110 500 (to replace a APC RS 500) runs much
warmer than I would like. I'm used to the APC RS line-interactive
units and they don't get nearly as hot.
Otherwise, the Eaton/MGE UPS's have been great, a 5PX and an
Evolution. The 5PX is kind of a cross, it has usbhid support and
Powerware's better battery management feature.
I tested the mge-shut (serial) driver on the 5PX, the functionality
and reported values appear identical.

I have a Eaton 5110, and I have been working on adding functionality to
the bcmxcp driver. With my changes, the 5110 reports a bit more
information, but not "battery.runtime", that information is not
supported by the hardware. I guess the 5110 is one of the most basic
models, and provides not too much info.
Unfortunately, my 5110 had a hardware failure a month ago, so I have not
been able to do further work.
But I have ordered an Eaton 9130, which also supports bcmxcp, so I will
continue testing on that one in a couple of weeks.
With my driver changes, the driver should report everything the hardware
is capable of supporting.
My changes have not been merged to the master branch of nut yet. Some
work has been merged to
https://github.com/networkupstools/nut/tree/bcmxcp, and the rest of my
changes are at https://github.com/networkupstools/nut/pull/47
I have no relationship to Eaton, I have just bought their product
because they provide open documentation on how their protocols work, and
work nicely with the nut software.
