I have replaced all my outlets and switches, thermostats, with insteon devices, added motion detectors, smart hinges, garage door sensor/controller, a ELK security system. I have a universal Devices ISY controller that controller everything, and I mean everything. Even my irrigation system is controlled with a insteon compatible controller. I have thought about all the work to either take it all out or take 6 months to train the new owner on what all the scenes are and all the programs, and how they could modify them to fit their needs.
