We created a floorplan interface using an RTI KA11 controller. As the people in the home move room to room, the floorplan reflects who is in each room. Scenes are triggered during certain hours of the day depending on who is in the room, and who is "in control" in that room. Lot's of possibilities with the driver and the customization of RTI. Great driver!
Have you considered setting up an IFTTT channel for handling the enter/exit events?
