On your mobile device, open the Google app and either tap the mic or say "Ok Google" to get started. Then say, "turn the temperature to 70 degrees". In Chrome, either tap the mic or type directly in the search box to set the temperature.The Google app will also bring up Now card notifications based on location to help users adjust temperature even when away from home.
