For example, using the "OK Google" command will allow you to say additional phrases like "change the temperature to.." or "set Nest to..." and your device will adjust accordingly.
In addition, there will be a new Google Now card that will display when the system had adjusted itself.
As with most apps, you will need to opt-in to give Google access to your Nest account, and to enable the Nest Google Now card. Just like with many voice commands, the abilities are limited, at least for the time being, but it is still very cool to be able to change the temperature without having to get up.
