How does Lyric know when your home is empty?

The Lyric app uses your smartphone's location services to know when you cross the geofence boundary. Your geofence will trigger only when you cross the geofence boundary. When you leave your home and travel outside of your geofence range, your system will change to Away mode. When you are returning and cross back inside your geofence boundary, your system will change to Home mode. If you have multiple users using the Lyric app, the geofence will trigger when the last person leaves the house and when the first person returns home.
