Now that I understand how the Geo-Fencing works I am a big Fan. It has solved a major problem with my occupancy solution. I use motion sensors around the main travel areas of the house to determine if the house is occupied or not. If not, the house shuts down after 20 minute timeout but not before sending me a text 5 minutes beforehand.
The main problem has been if I take a nap, or get involved at the computer where motion is minimal. I'd keep getting text messages at which point I'd have to move around to indicate my presence.
With Geo-Fencing I can use my iPhone to only allow this to happen if the iPhone is out-of-region. It works as normal if I am away from the house to allow it to function when the cleaning crew arrives for example, but will override the function if I am home with my iPhone.
This has solved a huge inconvenience for me, thanks for continual improvement to a great app.
