Was browsing through Amazon when I noticed an ad for a new Nest Thermostat selling for $129 with a picture next to it. Once I clicked it I was taken back to the amazon home page.
That sounds like the Nest E. That's $10 off their normal price. (Not that it's a bad thermostat - I've been running it for a while. It's easy, it saves money, it allows me to not run much AC if I'm going to be out for a few hours (I can tell it to start cooling down from anywhere [in the world] I can access the internet, etc.), but it's not anything new.
The differences are:
The Nest Thermostat has a full-color display and a feature called Farsight that will show you the time, weather, or temperature from across the room. The Nest Thermostat E has a frosted display that only shows the indoor temperature.
(The app shows outside temperature and the E shows the display when you walk around.)
The Nest Thermostat works with 95 percent of homes. The Nest Thermostat E works with 85 percent of homes.
(If it works with your home, it works.)
The Nest Thermostat has a metal ring and comes in multiple colors. The Nest Thermostat E has a plastic ring and only comes in white.
($100 for metal and color?)
