I would really recommend fixing the wiring before investing any money in home automation.
Don't build advanced sensitive low voltage systems on top of shaky high voltage systems that can melt and destroy them. Not having enough outlets because of old shoddy wiring is inconvenient when you can't plug stuff in and waste time running extension cords, it's expensive because you end up buying that much copper to run extension cords, it's expensive because shoddy wiring can easily fry electronics, and it's tragic and expensive when it burns your house down.
