The Google owned company which is &nbsp;the home automation producer of programmable, self-learning, and sensor driven gadgets provides the classical thermostat devices. &nbsp;Thermostat E, which is the latest addition to the Thermostat series by Nest works exactly the same way as the 3rd generation model of Learning Thermostat works, but available at cheaper price. For the people who prefer efficiency over &nbsp;the design, Nest compromised with the former device &nbsp;looks and interfaces to make the new model accessible at affordable price.Thermostat E is the cheapest member of the family, but operates with the same efficiency as the other models. Replacing the glossy metal ring with plain white polycarbonate and reducing the resolution to 320*320 panel is what makes model E look unfussy. Further, Polarized glass is used to intentionally blurred the screen in order to add a softness in it.Apart from these changes the model is identical to Learning Thermostat when it comes to functionality.The price of the Thermostat E is $85 cheaper than its predecessor. &nbsp;The smartphone controlled Thermostat E also has &nbsp;internet connectivity . The device &nbsp;uses the smartphone to know whether you are home or not in order to adjust the temperature of house accordingly.
