We are shifting to our new house so I'm thinking of getting a home automation setup. I want to be able to control lights (well, lamps really), home theater (mostly audio, including set zones around the house) from a central touch screen/smart phone/web interface. I'm also looking into pet feeders as well, that you can load up with dry food and set to a timer. Will list down some more things that could be automated.

However, I am unable to decide which brand to go for or where to get more information on home automation. I want to be thorough before making any decision.
