Hi CPickler,
Are you using the the CM15a or the CM19a interface at the AHP computer?
What is the distance from your DS10a (garage door switch) and the above interface?
It is possible that the CM15a or CM19a is to far from the DS10a and not sensing the change.
When you installed/setup the DS10a in ActiveHome, did it recognize it right away?
Cheers,
Nate
