Bubba, IF the receptacles are on different
branch circuits, remove each of the light
bulbs and drop a penny in each socket and
replace the bulbs. Now while standing very
near your breaker panel, use a Palm Pad to
activate each receptacle one-at-a-time. If
no breaker trips, no lamp is plugged into
that receptacle, in that room. If a breaker
trips, a lamp is plugged into that
receptacle on that breaker. Observe the
label for that breaker to tell you what room
it is in.
Be sure and post your question on at least
three more forums for even more helpful
answers.
(You can't do it without X-Ray vision, and
that would be the Superman kind, not the X10
kind...OK?)
