It would be just like monitoring any regular
X10 address such as an X10 switch, etc. I
use the CM11A to monitor all my motion
detectors all programmed for address A1 to
A3. The CM11A polls the PC when a
transmission occurs on the mains, I decode
it and tag it with a custom description
(string), thats it. The CM15A can do it too,
but using the SDK and hopefully someone else
can fill you in on the details, but YES IT
CAN BE DONE!
