The two most certain defects of the multi unit ID work are invisible to
the offline suites, because they only appear once a discovery has
actually run: the orphan sweep deleting the children of the other
connection, and the aggregation of the connected state.
This suite mounts the plugin behind a real ThingManager against a real
device. It is deliberately not a testcase, so "make check" never runs
it, but it is still built so it cannot rot unnoticed. Without
SUNSPEC_TEST_HOST every test skips, and no address is written into the
repository: the address of a real installation is customer data.
NOT YET RUN against hardware. It needs the address of a GEN24 and, given
the polling rate guidance, a deliberate decision to point it at a
customer inverter.
