Yes, that's an absolutely viable option as "connected device" but that is not how "Smart" works. I believe that the next big thing in computing is the removal of unnecessary screens and interactions. The next paradigm is a device that is able to seamlessly do for you the routine/predictable tasks you usually do. Replacing a wall switch with an iPhone app doesn't fall under that paradigm.
