After all my readings here, i know that the answer will be probably "NO" but, here is my question.
I'd like to get motion sensor to be on "home" is there is way to do that ?
You'll need to clarify where you'll be with respect to the rooms with the Motion Sensors when you say "I'm there".
Why not install a non-security motion sensor in the basement plus a transceiver and chime. Since you'll be in the house you'll be alerted and can take whatever action is necessary.
Also w/ X10's OnAlert (and a running computer) you could trigger all sorts of things when the SECURITY motion sensor is tripped.
But Charles idea is simpler.
