This will be the first product from Amazon in my Home Automation arsenal, other than a dash button, which is singular use.
I have yet to purchase anything via voice, but my door unlocks and lights turn on via motion with geo-fencing and motion sensors; appliances, lights and electronics turn on and off via voice; music and TV selections are made via voice; and the temperature control is done via a combination of both voice and geo-fencing.
Weather and purchases are short sighted, and home automation is the future whether or not you let the kids play on your lawn.
