GC-SP1 Question

[rdmustang]

I know this question doesn't directly relate to LMCE but it is somewhat related.

Does anyone know how to use the GC-SP1 to determine whether a device is turned on (like my receiver, tv, projector, etc)?  I've asked Global Cache but they won't respond.  I also asked SmartHome and they didn't know.

any time a signal is found, the contacts are closed. You can use this to trigger events from a generic sensor point of view.

I understand the concept of how it works.  What I don't understand is how to get a low voltage output from a device like a receiver, tv, or projector.  Global Cache says to use a "wall adapter" but I can't figure out what that is, GC won't respond to inquiries and SmartHome doesn't know either.

What would I hook the wires up to on the GC-SP1?

Thanks!
