At the heart I want a super computer running the house in much the same way that Jarvis does in Tony Stark's home. Voice recognition and good sound in every room. A house database that keeps track of everything about the house and captures information for prosperity about my life. It should handle all communications, voice, video and fax and keep records of all that. I've started to build a website to capture all the ideas for it.
I'm a currently homebody living out of an apartment. I see customizing a small but comfortable smarthome for myself to be an excellent hobby.
