Programmable thermostats are proven to reduce the cost of heating in homes but the new Nest 2.0 sure takes it up a notch. The second generation thermostat looks pretty good, and will connect with more heating and cooling systems than the original.
The Nest 2.0 is 20% thinner than the original, and the design has been altered somewhat. The single, solid stainless steel ring surrounds a sleek lens, that shows the digital display of the thermostat. The lens replaces the grille from the first generation. It also comes with an updated thermostat. The new asterisk connector will allow you to use this with a lot more heating and cooling systems. It can even tackle three-stage systems that include heat pumps.
As with the original, the Nest 2.0 can automatically generate a custom schedule based on the way you use it, and can be remotely operated from your smartphone, and its updated app is available for both iOS and Android devices. The Nest 2.0 sells for $250 (USD).
