Agreed.

Maybe this could be documented on
http://www.networkupstools.org/doc/2.2.0/new-names.html ?

Hehe, of course, I didn't expect you to fix my hardware ;) I was simply
sharing the information in case other NUT users are interested.

BTW, I _did_ complain about that to APC. They are currently
"continuing to work on my issue". I am not holding my breath though, I
reported it to show them that at least some users care about power
consumption, but I don't expect them to fix my hardware either.

Thanks,
