How is that one wired?

Which NUT version? Looking at the values below, this probably is the
version from the trunk, otherwise the override with 'SD=ST' would be
ineffective.

What exactly did you test here? Have you run 'upsmon -c fsd' both with and
without mains present? What was the behaviour of the UPS in these cases?

We could test for the latter too, to get some rudimentary UPS connected,
so this is an interesting concept.

Not so fast. It clearly doesn't match any of the existing types, but we
need to be sure that it really behaves as expected before adding a
supported type... :-)
