Good evening.
I've written a plugin to interface Geohopper and/or Beecon to Indigo. I built it primarily because I wanted to play around with iBeacons, but it should work just as well with Geohopper's geofences.
It's my first plugin and I've written it over the course of the last two days so don't expect something 100% bug-free, but I feel it works fairly well.
I wouldn't mind some feedback. Try it, and enjoy.
