I'm doing a house remodel, and i'm curious about the state of home automation systems. Guess i'm looking for something that would give me control over as much as possible; lights, HVAC, irrigation, cameras, etc. It looks like Ipad is taking over as the control unit, which would be a great solution for me. Anyone have experience with what's out there, and have recommendations? UDP? Z Wave? What is all this stuff? Help!
