Please, please, please be a completely open, extensible platform...<p>I want to be able to control my Apple TV with my Google Home device.<p>I want to be able to control my Phillips Hue and LiFX bulbs.<p>I want to be able to build my own custom home automation server endpoints and point my Google Home commands at them.<p>I want to be able to remote start my car with a voice command.<p>I want to be able to control my Harmony remote, and all of the devices connected to my Harmony hub.<p>I want to be able to access my Google calendar.<p>I want to be able to make hands-free phone calls to anyone on my Google contacts.<p>If my grandmother falls, I want her to be able to call 911 by talking to the Google Home device.<p>I want to be able to ask wolfram alpha questions by voice.<p>I want to be able to have a back-and-forth conversation to arrive at a conclusion. I don't want to have to say a perfectly formulated command like, "Add an event to my calendar on Jan 1, 2016 at 2:00 pm titled go to the pool party". I want to be able to say, "Can you add an event to my calendar?", and then answer a series of questions. I hate having to formulate complex commands as a single sentence.<p>I want to be able to have a Google Home device in each room, without having to give each one its own wake-up word. Just have the closest one to me respond to my voice (based on how well it can hear me).<p>I want to be able to play music on all of my Google Home devices at the same time, and have the music perfectly synchronized.<p>This is my wish list. I am currently able to do more than half of these items with Amazon Echo, but I had to do a bunch of hacking and it was a pain in the ass.<p>If Google Home can deliver on these points, I would switch from Amazon Echo in a heartbeat.
