Product Description
From the Manufacturer
A Thermostat for the Smartphone Generation
The next generation Nest has a new, slimmer design, is enclosed by a solid stainless steel ring, and works with 95% of low voltage systems.
The Nest Learning Thermostat learns what temperatures you like, turns itself down when you're away and can be controlled from anywhere over Wi-Fi. By programming itself, the Nest thermostat can save up to 20% on your heating and cooling bill. You just have to teach it well.

Let's Stop Wasting Energy
Your thermostat controls about 50% of your energy bill - that's as much as the refrigerator, lighting, TVs, stereos and computers combined. Problem is, a lot of that energy is wasted heating and cooling an empty home.
Programmable thermostats were supposed to help, but 89% of people don't even bother to program them. They're just too complicated.
That's why we made Nest simple. It's so easy to use that 99% of Nests have custom schedules.
Control From Your Wi-Fi Connected Nest Account
Simply connect the Nest Learning Thermostat to your home Wi-Fi to control it from a smartphone, tablet or laptop. Change the temperature, see and adjust your schedule or settings, and see exactly how much energy you're using.
Detailed Energy History is available on the Mobile and Web app for the last 10 days and Nest sends you an energy summary every month with tips to help you save more.
Nest is secure, private, and reliable. Nest supports HTTPS, SSL and 128-bit encryption.
Programs Itself, Saves Energy
Nest is the first thermostat that learns from you. After about a week, it knows your schedule and temperature preferences and automatically activates features to help you save energy.
Auto-Schedule
Turn it up, turn it down. Nest remembers what temperatures keep you comfortable and creates a custom schedule for your home. As your life and the seasons change, Nest automatically adapts.
Auto-Away
Nest uses its activity sensors to sense when nobody's home and turn itself to an energy-saving temperature. Auto-Away works in 90% of homes, even if Nest is in a room you don't use much.
Airwave
Airwave automatically turns off the AC a few minutes early, but keeps the fan running. Airwave keeps you just as comfortable but runs your AC less.
System Match
System Match automatically turns on specific features for your heating or cooling systems to make you more comfortable and help you save energy.
Personalized for Any System.
Nest knows one size doesn't fit all. So you tell Nest what system you have and System Match will turn on specific features to automatically help you save.
The Nest Leaf
Whenever you make a choice to save energy - like choosing an energy-efficient temperature - you'll see a Nest Leaf. People who earn a Leaf every day save 10% more on average.
Energy History
See exactly when your system was on with Energy History, then get a summary of your entire month's energy use with the Nest Energy Report. The more you know, the more you can save.
Early-On
Get the temperature you want when you want it. If your schedule says 72°F at 6 a.m., Early-On will start heating or cooling early so it'll be 72°F when your alarm rings.
Filter Reminders
Nest reminds you to change your air filter based on how many hours your heat or AC has run. A clean filter can cut 5% off your heating or cooling bill.
Heat Pump Balance
Heat Pump Balance minimizes how often you need to use expensive auxiliary heat. Just choose whether you want more comfort or more savings, and Heat Pump Balance will automatically adjust when AUX comes on.
True Radiant
True Radiant is a Nest exclusive that gives you a predictable schedule and even heat. No more frustrating guessing about what temperature to set when.
Easy to Install
We designed Nest to be a quick, easy install: three out of four people install Nest themselves in 30 minutes or less. If you're comfortable installing a light fixture, you can install Nest. Everything you need comes in the box. Too busy? Learn more about Nest Certified professional installation at 855-4MY-NEST.

Product Description
Customer Reviews
There are Nest only exclusive cost-saving features on this device. So please no ranting on how this is just another overpriced thermostat for those who are reading reviews and are against this product. Move on to another product where people care instead of being a Debbie downer. My two favorite features of this unit are the auto-away and air-wave technologies (for the A/C) which are probably the two most cost saving features for me. Air-wave shuts down the compressor before the push box. Since the coils are still cold from the compressor running, the thermostat knows how long it takes for your home to get from one temp to another. Depending on this time, the thermostat knows when to shut down the compressor to save power while still getting the home to the desired temp. Auto-away is a feature that shuts off the AC within a programmable range if it detects no one is home. My unit is in a hallway that doesn't see much traffic (I spend most my time in a back office) and this unit still managed to not go into auto-away mode while I'm home. A side note on auto-away though is that it must be trained within the first two weeks before it has an idea of your home activity. Once the unit trains itself, the power saving features will all be automated unless you manually disable them.
As everyone else has claimed, the setup was quick and easy for both the thermostat and wifi to access a personal profile/account. The tools to install the thermostat are generously included with the premium price. Packaging was premium and very Apple-like; a nice presentation.
Yes, like mostly everyone else, I realize $250 is a lot to spend on a thermostat. I don't mind spending that kind of money on something that is going into my home that will be used 24/7. If you don't mind the price hurdle, I'm pretty confident you'll be happy with the performance, company(Nest) and style of this thermostat.
I'm very happy with this thermostat if its anything like the 1st gen in performance. If it doesn't perform, expect a followup to this review. As of now, I'm very pleased assuming the only real differences I'll be expecting from the 1st to 2nd gen is aesthetic appeal.
If you have any questions, I'll do my best to respond. Also, before giving a review a thumbs down, provide a suggestion for making it better. Thanks.
----------update (12-12-12)--------------
I just wanted to mention then 2nd gen is on par with the 1st gen thermostat in cost savings and performance.
***DO NOT ATTEMPT TO REMOVE THE FILM FROM THE BOTTOM OF THE UNIT*** I am one of those remove plastic wrap from everything kind of guys. Guess what, that isn't plastic wrap on the entire bottom of the Nest ring itself. It's the sensors. Don't scuff up your Nest!
It took longer to unbox it then it did for me to install it. It helps that I only had 2 wires, red & white to connect. Connected to my Wifi easily. It then downloaded a software/hardware update 3.01. After that it was pretty painless.
Looks great on the wall. If you think the stainless ring reflects the color of your wall like they say it does, then you are willing it to happen.
I never had the Nest 1 to compare it to but this one is very sharp looking. Everything in the box was well packaged.
Mainly got this unit for the fuel savings and the fact that it does not need a "C" wire to work like every other fancy thermostat.
Android app works perfectly over 4G or Wifi. Running ICS on a Droid Razr.
Unit does have an Anti-Freeze temp setting since someone asked.
I was pretty surprised to come home today to a sweltering-hot apartment when the outside temperature was in the mid-to-high sixties. It's a brand-new apartment, very well insulated, and initially I simply thought that all the sun streaming through the skylights and windows was responsible for the high temperature. The Nest indicated that it was 86 degrees inside and of course, with a set point of 50 degrees, it was obviously not heating. (Right?) I set the temperature to 75 and switched it to cooling mode. Cool air started streaming from the AC vents - great. Should cool down in a little while. (Right?) After thirty minutes with the AC on, I was if anything more uncomfortable, so I went over to the Nest again - imagine my surprise when I saw that the inside temperature had gone up to 89 degrees! At this point I knew something was very wrong. It took only a few seconds to determine that the Nest had my heating on full bore - even while the AC was cooling. No wonder the place was sweltering! I called Nest and after a very short debugging session (the customer service agent had obviously seen this many, many times before) he determined that the Nest had failed in such a way that the heating was stuck on, full-time.
The rep informed me that this was a known issue that Nest's engineers were trying to solve. Apparently the Nest, unlike a cheap hardware store thermostat, is extremely sensitive to voltage "spikes" on the wires that connect it to your HVAC. Such spikes are pretty much par for the course in an HVAC environment - those wires are connected to electromechanical relays, transformers, and other old-school electrical gear - and regular thermostats are designed to deal with it, which is why you don't have problems with your cheap Honeywell. (The one I replaced with the Nest had been doing its job happily for the better part of a decade.) But this electrical "noise" can make the Nest fail - and fail spectacularly, typically by leaving the heat (or cooling) on full time, or else keeping them from coming on. Any of those failure modes could get pretty expensive if you happened to be away when they happen - you could burn through a lot of fuel and/or use a lot of electricity, and in the worst case scenario your pipes could freeze and flood your house. Nest knows this, so they are no longer replacing thermostats that fail this way (since their hardware is flawed, any replacement is just going to fail again, and the next time it could be a lot worse). Of course, they won't tell you this in so many words: the company line is that your system (because it exhibits voltage spikes) is "incompatible" with the Nest. Never mind that it is a bog-standard HVAC setup, passed their compatibility test with no issues, and has worked fine for a couple of weeks). Never mind that it works fine with a garden-variety hardware-store thermostat. Naturally Nest doesn't want to admit that their fancy hardware is seriously flawed in its inability to handle the kind of electrical noise that is found on ordinary HVAC control lines, but make no mistake about it: the fault isn't in your system. It's in their thermostat, which isn't designed to handle real-world conditions.
This isn't just a matter of semantics. The problem is that, if you purchased your thermostat from Amazon, Nest wants you to return it to Amazon (not to them). They are explicitly disclaiming any responsibility under their warranty - since it's your HVAC system that's "incompatible," not their thermostat that is broken. Presumably if the thermostat fails outside of Amazon's 30-day return window you're out of luck. At least the Nest would make a nice paperweight. This is the part that really shocked me and made me feel that the company must be getting a bit desperate. Reading the online forums, I can see that this is a pretty common problem, and I suspect that Nest financially can't handle the number of returns it would have to handle if it treated this as a warranty issue. Fortunately, my Nest is only 3 weeks old, so I can return it to Amazon, but I really hate to have to do that - it seems like an abuse of Amazon's generous return policy, when it's really Nest that should be facing up to their problem. I feel very sorry for those whose devices fail, excuse me, prove to be "incompatible" outside of the return window. At least I kept my old thermostat rather than recycling it as Nest suggests I do!
Nest has a serious engineering problem on their hands and I believe they are scrambling to do something about it before it all comes crashing down. (The rep offered to put me on a mailing list to be informed when their engineers fix the issue, presumably so that, I can court disaster again by buying the next version.) They've had a lot of really great press (not undeserved, because their device *is* really nice, when it works) but that can only carry them so far - if the news gets out that their $250 thermostat could leave you overheated or flood your house, they're going to lose that momentum. So it's not surprising that they're trying to frame this as "merely" a compatibility issue. But if I had a Nest at this point, even if it seemed to be working OK, I would still be really, really nervous about it, for two reasons: (1) the device is not robust to typical levels of electrical noise; a voltage spike could happen on any system at any time, possibly breaking the Nest and subjecting to you God-knows-what financial loss, and (2) it's not clear that the company would stand behind their product if that did happen.
Advice: stay far, far away from this product.
