Home Automation - Google

When will Google really jump into the home automation or whole home networking game?

Imagine this:  you come home and your door unlocks because your blue tooth is recognized by your front door smart lock.   As you enter the lights come on room by room and the temperature adjusts to your presets.

You remember you have a question so you ask your house - "Betty, what is the weather going to be like in mountain view"   then Betty answers in your best voice.   Well Jason, in the morning it will be slightly overcast but will warm up in the afternoon.    The nice thing is she gave me the temp in human terms not spoken like a computer - it will be 65 degrees in the early morning, 75 degrees by lunch... etc.

Come on Google buy Leviton and get on with it.
