User presence detector

Sensor processors inactive when RFID is detected.

Better yet. A super simple mobile app that detects home presence via geo-tagging or geo-fencing and alerts the notification processor that the user is at home and should not send notifications to the user.

The Notification Processor must stop sending notifications once it detects the presence of a user.

This can be done by assuming that users will always have their smart phones on them. One way is to detect the presence of the phone (e.g. MAC address) on the network using something like arp or arp-scan.

We could also place sensors in the garage (e.g. parking sensors) and based on which car is not in the garage, send that person notifications.
