Nest’s smart thermostat is about to become even smarter

Nest’s Learning Thermostat is about to become even more useful. This morning, the company announced that all generations of the device will be receiving a big update over the next couple of weeks, which will improve the device’s ability to maintain your preferred temperature in your house, no matter how drafty your house is or what the weather is like. More useful than that, however, is the improved energy efficiency, with updated thermostats being able to save anywhere from 3.8% to 6.5% more energy than they already save.
