Chamberlain CWA2000 Wireless Motion Alert System

Hey Guys,

Anyone have any experience with the Chamberlain CWA2000 Wireless Motion Alert System. I am getting ready to purchase and wanted to see if there is anyway to hack the base station to announce over the sonos when someone is in the driveway.I have checked out other driveway alarm topics here. This seems like a pretty good option. I would just like to send the notification to the rest of the house.
