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.
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.
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 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.
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%.
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.
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 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 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.

Top customer reviews
There was a problem filtering reviews right now. Please try again later.
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. People buy this so they can remotely monitor the house, vacation house etc. when they are not home (see my buying reasons above), they need to see what the temp is to see if there is a problem. They need to fix this. Android app was not updated since it was released. I hear the Apple app is better and was updated several times. On the other hand, the convenience is great.
Set point anticipation: As mentioned above, it learns how long it takes to reach the temp (and shows it) but it does not use it (or weather it gets from the internet) to start heating ahead of time to reach desired temperature at desired time. It only turns the heat at the specified time. I have a radiant forced water heat and it takes 30-40 minutes to reach the temp. This makes the learning feature a bit useless since you have to change it later anyway to have a warm house when you wake up. Most much cheaper programmable thermostats have had this feature for very long time. I would absolutely expect this for the price we pay for this stat.
Reliability: Reliability is the biggest problem with this gadget. Nest pushes a software update to the unit roughly once a month. The update can happen randomly when you are not home. Every time the update would take place, my unit would lose all settings. Schedule (that took 3 weeks to learn) gone, Internet connectivity account gone, location setting gone, heating system details gone. All accumulated learning data gone. Heat shut down until I come home and re-set the tstat. This would happen with three software updates. On a separate occasion, Nest cloud server was down and the stat trying to connect to the cloud drained the battery. Drained battery causes loss of wifi connectivity and disables your heat and control of it until charged. Wifi never automatically restores. All this was happening in dead winter with single digit temps outside. All you get on internet or a smartphone is a little "?" and a a statement that your stat lost connectivity. I was not travelling but can you imagine the scenario when I would be away for a week? Who would pay for frozen pipes damage? This is unacceptable. Stat should be a device that is dead reliable beyond a grain of doubt. Obviously, California designers do not share concerns of customers residing in cold climates. This made me to disable the key feature of the stat: learning (I do not have another 3 weeks patience for re-learning each time). I have asked Nest tech support to implement a feature that would need a user input to execute the software updates to prevent system sutdowns like this in ones absence. Still not implemented. Nest support recommended that I disable the wifi on the tstat to prevent updates. Another key feature and very reason I bought it. This would be likely the one most important reason why I'm considering switching to good ugly but trusted Lux or Honeywell. Since then the stat was replaced by Nest but problems continue.
Daylight savings time: This is with the replacement thermostat. Wouldn't you expect the smart stat be smart enough to handle DST switch? I would! Especially for the price paid. Well, it did learn new time automatically but guess what. It did not apply it to my schedule! How smart is that? I had to go in and reprogram all timepoints for all days in the week because they would be off by 1hr. That is ~28 time points! Come on, who wrote the code for this? My old Lux stat did not handle DST automatically either but only change needed was the clock!
Swing value: Nest does not have the ability to change the temp swing value. All other cheaper programmabe stats have had this basic feature for years.
Temperature hold: It does not have the hold feature. I would use hold feature when home on a weekday, like on holiday, Thanksgiving, or when sick home when I do not want to run my normal program. Any other cheap thermostat has this feature. Nest does not. The Away feature is not the same as hold. Hold should be one touch easy to use. The Away is buried in menus and generally reserved for low temperatures in cold season and not meant to be changed.
Energy use: By now it is well known that programmable thermostats do not save energy so they were taken off the Energy Star list. They preheat your house when you sleep and when you are not yet home from work. You would otherwise wake up or arrive to cold house with the manual stat and change it then. Nest takes this concept one step further. It allows you to preheat the house remotely when you are not yet home. Which you would otherwise need to adjust upon arrival home. Energy saving? Not. Convenient? Yes. Not a complaint, just saying...
Let me conclude with a paste of a section from Nest warranty statement. Like me, you probably did not read it before purchasing:
NEST LABS DOES NOT WARRANT THAT OPERATION OF THE PRODUCTS WILL BE ERROR-FREE OR UNINTERRUPTED OR THAT THE PRODUCTS WILL IN EVERY CASE PROCESS ALL DATA CORRECTLY.
and, in the case your pipes froze after a software update
YOU WILL BE SOLELY RESPONSIBLE FOR (AND NEST LABS DISCLAIMS) ANY AND ALL LOSS, LIABILITY, OR DAMAGES, INCLUDING TO YOUR HVAC SYSTEM, PLUMBING, HOME, PRODUCT, PRODUCT PERIPHERALS, COMPUTER, MOBILE DEVICE, AND ALL OTHER ITEMS AND PETS IN YOUR HOME, RESULTING FROM YOUR USE OF THE PRODUCT INFORMATION, SERVICES, OR PRODUCT.
As of now, I cannot recommend this product. It looks great but that's about it. I recommend searching the web for more reviews as there are other problems reported but not experienced by me so therefore not included here. Many reviews concentrate on ease of installation. Yes it is true but ultimately you need a solid one-season-of-use review.
Update 04/08/2012: OK Nest released a new software update 2.0 which fixed/improved following features:
1. Android app was finally updated. Now I can see my temperature while in Away mode (auto or manual) or while off. I can now see and edit my schedule. +0.5 stars.
2. Reliability: Not really software related... They replaced my unit and it now survived two software updates without resetting itself or shutting off my heat. +0.5 stars. Maybe by next winter, I will trust it again....
All other feature and problems mentioned above are as before. Oh, one feature I forgot to mention: Some users complained about temperature accuracy (not me). Nest does not have a temperature calibration feature (common for many years on any other thermostat). Your only way to correct it is through exchange for another unit with Nest.
Update 07/15/2012: Apparently, this was not clear. This is a THREE (3) star review. NOT four (4) star review. Before the release of Nest 2.0. I had it as TWO (2) star review which I updated to THREE (3) star review upon release of Nest 2.0. Also, no comment on A/C-related features. I don't have A/C.
Nest apparently asked Houselogix to stop selling this driver (likely under threat of litigation).
That's all fine and dandy, but they then released a "software update" that disabled the function of the driver.
It was a rude awakening for some users to find that there thermostat was no longer responding to there inputs and home automation programming.
Tell me what is the point of spending $250 on this unit, if the company that produces it will do anything to ensure that it is only controlled the way they want it controlled.
In my opinion they crossed a fine line by deciding how users can use the equipment they *already* paid for.
** Note here to those who still purchase: don't install early in the weekend in case there are problems. Contractors aren't available til Monday unless you pay $$$$.
Installation and setup was a snap. It was installed and programmed in less than 30 minutes. Everything worked fine that afternoon - I tested that it turned the system on and off when I set a high and low temperature. I thought everything was fine when I went to bed. That was the last hot shower I had in 4 days.
I woke up the next morning to no heat in the house and no hot water. The boiler heats water that is circulated through the house for heat (controlled by the Nest), and a hot water tank to showers etc.
The nest was hooked to a Weil-McClain Gold CGI series2 boiler. Inside this boiler there is a 120V-24V transformer and a controller circuit board. There are a series of LEDs on the controller, the first one is green that indicates power. It was now off. I went through the troubleshooting guide for the boiler and found that it was either:
1) no incoming power
2) bad transformer
3) bad circuit board
After verifying that it wasn't incoming power, I called nest customer support. I was on the phone for about 45 minutes opening a "priorirty ticket" as I now had no heat or hot water. I also started lining up a boiler repair man.
This was on a Sunday.
No call back from nest CS the next day: Monday
No call back from nest the next day, again: Tuesday
I then called them back on Weds. They "didn't know that it was urgent" and that it had been "escalated to engineering". So much for a priority ticket. I told them that I didn't have heat or hot water when I opened the original ticket.
No call back from nest on the next day either. I had the boiler repaired today, myself. Had to take the day off work to meet the repair guy (who was 2 hours late). It turns out the 24V transformer died, which also fried the controller board. Having the nest hooked up to this 24v transformer caused some interaction that caused it to go out.
Thursday: I called them back again to get an RMA. This was a 35 minute call to get the fed-ex label made.
Friday: go to fedex and wait in line only to get up there and have the label printed and the "To" address was back to my house! Their CS agent messed up the label.
Friday: another 20 minute call to Nest to get another label. I still have to take it back to fedex. Beyond angry at this point.
Friday night, a full 5 days after I opened my priority ticket, I get my first email contact back from nest customer support, saying "It is unlikely the nest caused this issue", but they want to work with me to try and resolve the problem.
Gee thanks! Nearly $350 later in repairs, no heat and hot water for 4 days and that is what they have done in sum total so far.
AVOID NEST until this thing is tested more...Don't be one of their guinea pigs because their support in getting things resolved in case something goes wrong is HORRIBLE.
