We've identified a minor bug that can cause multiple triggering if you're using the geoFenceInRange True/False variable. I've identified the cause and I'll fix it later today and release a new version. Thanks for finding the potential problem.
BTW Alpha testing is going well and the core system is gaining stability. At Jay's suggestion I'm going to add the functionality to add devices individually as well as in a group as well as tidying up some of the naming conventions to make it easier to understand. Watch this space

Mike
