Geofence your heating using an iPhone

Hi All,

I have put together a summary of a project that I've been working on recently - I have managed to geofence my heating using an iPhone. This means that the heating automatically switches off when no-one is home.

I've got no idea whether this has been done before or not, but I thought i'd share a few pictures and diagrams.

Please let me know what you think:
