Nest Thermostat E
Through three generations, the Nest Thermostat has kept largely the same design: a black circle surrounded by a ring of metal. The Nest Thermostat E is the company's first to move past it, with a white body and a frosted display that's compared to a watercolor painting. Otherwise, it's much the same as its predecessors, giving you remote control over your heating and cooling, the ability to turn your system off when you're away, the ability to learn your habits and custom-configure a schedule, and, for the first time, a pre-set schedule that can start saving you money right out of the box.
