"These are some illustrations and some screens of exploratory UI for a mobile app for Android and iOS, which is now a deprecated project. The app was to control a smart thermostat and had a very visual UI which needed to account and meet accessibility standards while also illustrating four main states and varying weather conditions outside the home. Each state was given a unique shape and a corresponding unique shaped UI icon for use in the app. Each of the four states (awake, away, home, and sleep) is illustrated with all the variable weather conditions."


Google now owns Nest, so that's probably one of the reasons why this app wasn't released. EnergySense was rumored to be the name of a Google service that lets you monitor and adjust energy use.
