My grandfather always used to play an old a.m. radio fairly loud near the doors / windows at his house whenever he left the house as a security deterrent for bad guys...make them think twice before breaking into his house. It would be really nice to switch on a "Home Security / Vacation mode" that would play selected music/radio stations at different random times...or perhaps have a calendar schedule very similar to a programmable thermostat schedule. All customizable from your Sonos controller / iphones /android device.
