Yes, that is one of the advantages of having Homeseer read the Caddx zones, you can do a lot more than just security with them.
For instance, I have Homeseer announce whenever a door or window is opened, I also have Homeseer play an alarm wave file and then announce which zone has been faulted when armed in "Stay" mode. I then have the lights in that zone come on (this gives me time to get the firearms, know exactly where to go in the home, and have the advantage of me being in the dark while the intruder is in the light). Then I have the Caddx default entry time timeout and sound the normal alarms, and then turn all the lights in the house on including a flasher outside the front.
Just create a simple script that turns A1 ON and have that event triggered by the motion detector. Have the script start a timer that will turn A1 OFF after five minutes.
