Hi Faraday, nice idea ! I am experimenting with iBeacons since a few weeks. What type / brand of iBeacons are you using ? I would like to use this technology to switch on the lights above my entry in my house. Sure I could use a motion detector, but then the light might be switched on by some stray cats. Using iBeacons for this purpuse would avoid that and of course it is much more fun to fget it working. So far, I have set up one of my Raspis as a stationary iBeacon. There are iOS apps which call a wrbserver (on Raspi) with some php code, which in turn could trigger some action (switching on light for example), but these app drain the iPhone battery pretty fast.
I am using Estimote and Particle iBeacons. I prefer particle iBeacons because they are more DYI friendly. There is a bunch more information about BeaconAir over on my blog at www.switchdoc.com along with my Raspberry Pi iBeacon scanning software and there is a full article on BeaconAir coming out in Raspberry Pi Geek Magazine in July.
I'm planning to put an iBeacon on my cat so he can launch mice from MouseAir.
