The huge stumbling block I ran into when I proposed looking into home automation with my wife was that we had very different ideas of what the "right" thing to do in any given situation was. The combination of lights she wants to have on when in a room are very different from the ones I want to have on, for example. So unless there was face recognition so the room knew who was there, it would never automatically do the right thing.

Also anything that involved having to use an app to do anything was a very hard No.
