Product Description

From the Manufacturer

We didn't think thermostats mattered either.

Until we learned they control about 50% of our home's energy bill. That's as much as the refrigerator, lighting, TVs, stereos and computers combined.

Traditional thermostats tend to waste a lot of energy, mainly heating and cooling your home when no one's there.

We designed Nest to learn from you. As a result, 99% of Nests have schedules that work with your life. And when life doesn't go according to schedule, Nest can help:

  • Forgot to turn down the thermostat before you left the house? Auto-Away will automatically do it for you.
  • Dreading the summer heat? Airwave keeps you just as comfortable but runs your AC up to 30% less.
  • Coming home early from a weekend away? Use your phone to adjust the temp on your way.

It's simple:
You'll spend on average $30,000 heating and cooling your home over the 20-year life of your system. In that time, the Nest Learning Thermostat, which takes 30 minutes to install and programs itself in a week, can save you $6,000.

Nest Packaging
Nest Info

Let's stop wasting energy.

That beige box on your wall controls about half your energy bill, but huge amounts of that are wasted heating and cooling empty homes. Programmable thermostats were supposed to help, but only 11% of people program them. They're too complicated.

So we made Nest simple: turn it up, turn it down. Nest will remember what you like and help you save energy.

Living with Nest.

Day 1: We've made installation easy. Even if you've never even considered installing a thermostat. If you're comfortable installing a light fixture, you can install Nest yourself. Most people install Nest in 30 minutes or less. Or, a professional can help.

Day 2: Learning starts once Nest is up and running. Turn it up when you're home, turn it down when you leave and in a few days Nest will have learned your schedule.

Day 6: Life doesn't always go according to schedule, so Auto-Away kicks in when you leave home unexpectedly. Energy History shows you how much energy you've used daily.

Day 7: The Nest Leaf appears when you're saving energy. Changing the temperature just one degree can save you up to 5%. The Leaf guides you in the right direction.

Day 8: By now, Nest has made a schedule for your home. One-off temperature changes won't confuse it, but change the temperature a few days in a row and Nest will catch on and adjust its schedule. When you teach Nest well, you can save up to 20% on your heating or cooling bill.

Day 90: Now that summer's here, it's time to switch from heating to cooling. Nest will start building a new schedule, just like it did in your first week. As you turn on cooling, Nest's Airwave technology can cut your AC runtime up to 30%.

Day 365: Teach Nest well and it'll not only pay for itself, but continue saving year after year.

Control your Nest from Anywhere

Control your Nest Learning Thermostat from anywhere.

Control your home's temperature from your laptop, smartphone or tablet when you connect Nest to Wi-Fi. You'll be able to see and adjust your schedule, change the temperature and check energy history from anywhere. Plus, Nest's software will automatically update.

Keep track of how much energy you use in Energy History and get a monthly email summary of how your energy use is changing with the Nest Energy Report.

Nest is secure, private, and reliable. Its security features include HTTPS, SSL and 128-bit encryption.

Programs itself. Saves energy.

Nest is the first thermostat that learns from you. Teach it well to stay comfortable at home and save energy when you're away.

Auto Schedule


Programmable thermostats are frustrating to program, so most people don't or they create schedules that don't match their lives. Nest automatically programs itself in about a week. It creates a personalized schedule based on the temperature changes you've made and continually adapts to your life.



Airwave automatically turns off the AC a few minutes early, but keeps the fan running. Nest's humidity sensor activates Airwave. When indoor humidity is low, Airwave can cut your AC's runtime up to 30%.

Nest Leaf

The Leaf

Want to know if you're saving energy when you change the temp? The Nest Leaf appears when you turn Nest to a temperature that's energy efficient. It guides you in the right direction. A 1-degree change can save you up to 5% on your energy use.

Auto Away Feature


Nest's activity sensors have a 150 degree wide-angle view, so that it works in most locations. About two hours after you've left the house, Nest will sense you've gone and automatically adjust the temperature to avoid heating or cooling an empty home.

Energy History

Energy History

Energy History shows you how your energy use changes on a daily basis. Check Energy History to see how much energy you save and why— your adjustments, Away, or the weather.

Time to Temp

Time to Temperature

Turning the temperature up higher doesn't heat the house any faster, so Nest helps you save by showing you how long it'll really take to reach the temperature you want. Nest has three temperature sensors to track your home's heating and cooling.


Easy to Install

If you're comfortable installing a light fixture, you can install Nest yourself. Three out of four people install Nest in 30 minutes or less.

Too busy? Professional installation is also available at 855-4MY-NEST.

I was very excited about this product when it was announced. I frequently travel in winter and wanted to monitor my house temperature remotely via wifi to ensure my pipes do not freeze etc. Most stats that can do that require a C wire that I don't have. Nest can do without.
Like others mentioned, shipping, unboxing, installation and looks are all top notch and puts other companies to shame. However, this is where it ends. At least for me. Before you read details, let me say I have been using this stat for >3months. Many reviews out there are written a day after installation upon being impressed by the looks and the ease of installation.

Learning: It does learn your schedule over time but it takes good 3+ weeks until it stops giving me "cold house morning" surprises and heating while I'm not there. Yes, initial learning takes about a week but full learning takes much longer. And, after all this, I still had to go to the computer to change my morning setpoints by 30 minutes so I don't wake up to a cold house because this stat does not pre-heat ahead of time even though it learns exactly how long it is going to take and knows weather outside. Search the web, this is one of the top complaints with the device. Eventually, I disabled the learning and just program it manually because it is much faster and more predictable and gives me no surprises (sort of, keep reading).

Auto-away: works reasonably for me but it might or might not work for you depending on how much activity you have near the stat.

Internet control: Works great from the PC but the Android app is seriously weak and desperately needs more features. You cannot see or adjust your schedule, and if the stat is in AWAY mode, you cannot even see the house temperature.

This is what thermostats should have been all along, simple, elegant, and they do exactly what I expect.

The lowly thermostat, why in the world would anybody ever pay this price for a new thermostat? Honeywell sells perfectly programmable thermostats for a whole lot less money. In theory, they save money on the energy bill. I now have a Nest thermostat, and I'd never buy or want to use another thermostat ever again.

November 28, 2014 Update: Something went crazy wrong with my heating system. After a while on the phone and doing some troubleshooting, Nest determined my thermostat was broken, or bad. You will not believe what Nest did - they replaced my two and a half year old thermostat for a brand new Generation 2 for free. Yes, they extended the warranty to cover the thermostat. That's great customer service.

After using the 2nd generation thermostat, I can tell you without hesitation, there is no difference between the two. Thinner is not that much thinner. The clamping is a little different for the wires, slightly improved. Bottom line - if you can get one of these 1st Generation Nests at a discount - buy it! You don't get much more with the new model.

October 2, 2012 Update: Nest just announced the second generation of this thermostat and dropped the price of version 1 $20. the new version is said to be compatible with more systems and is thinner. The software is identical between the two versions (all Nests are being updated to the same software version). The case of a good evolution that does not obsolete version 1.

The construction is impressive. The main body is brushed stainless steel. The face is rounded glass that looks like a lens. The face rotates with a pleasing weight and smoothness.

Verified Purchase
The Nest thermostat is a remarkable design, with incredible features, and really reinvents an often overlooked part of everyday life. In so many ways, it is a great device.

But - it has a fatal flaw. (see update below)

A flaw that makes it unsuitable, and in fact dangerous, for any part of the world where temperatures can drop below freezing.

Nest Technical Support agrees this flaw exists. And they are working on it. But they don't know when there will be a solution.

THE PROBLEM: After a power failure, even a brief power failure, the Nest often requires human intervention to restart and turn the heat back on. Not every time, but quite often.

This means that if there is a power failure during a winter vacation, even brief, you will lose your heat until you return home. This results in frozen and bursting pipes, and the resulting water damage to your home.

In theory, there is battery backup that lasts a week. In practice, it often does not. It sometimes only lasts for an hour. When the power goes out, the Nest repeatedly tried to connect to WIFI, burning through the battery's power in a short period of time. Apparently the software does not recognize that when the power is cut to the Nest, it is almost certainly off for the WIFI router. So, the battery drains quickly. This happened to me this week during a one hour power failure.

When the power returns, the Nest should restart, but often it does not. It did not restart for me. The device was not responsive for me. I needed to remove it from the wall, recharge it on a mini-USB cable for an hour, and restart the device. Then, it started working again.

This problem happened during summer, so there was no harm done.

As S Greene noted in his comment on 8/13, the original information provided by Nest customer support was inaccurate. The unit was defective and we have sent a replacement unit. We apologize for the confusion.

To clarify, in the event of a power outage, Nest goes into a deep sleep to conserve power and wakes up when power is restored. Human intervention is not required.
