Users had expressed frustration about not being able to master their thermostats. They needed clearer visual feedback after they took an action and more transparency into what the system was doing after they interacted with it.
Heating/cooling set point is a frequently misunderstood concept. Chart-like indicator to elucidate the relationship between current temperature and the set point range was implemented. Users in a multi-zone environments expressed a need for a sense of context: what's going on in the big picture? This was addressed this by displaying a configurable household map with a "you are here" map marker. Visual style elements, such as color and typeface, were chosen to give the app a simple, “homey” and familiar feel.
