You cannot use your location as the product has not been officially released in your area.
I am using it in South Africa. Weather, for instance, I have to say " weather in Cape Town ".
Google Home, although not officially released in South Africa, is pretty adept at handling all local information.
Amazon is leaving the market wide open to google. They could have sold it worldwide by simply stating that it may not be fully functional at your location. I had to do fancy footwork even downloading the app for IOS!
