    I really wanted to love it

    • Written by from Chesapeake

    I wanted to love it but I love being comfortable in my home more. I purchased 2 second gen Nests for my home and immediately I noticed that the batteries drained, they lost wifi, and then shut down. Several times I came home to a freezing home and had to light the fireplace while I manually charged the Nest with the mini USB. No help from Nest support and finally I had to replace them with the old simple programmable thermostats ($19.99 at Home Depot) - problem solved! Waste of $500.

    Reading the forums and comments lets me know I'm not alone.

    Great idea but flawed implementation - Heat Pump owners be warned

    • Written by from Beaconsfield

    Great aesthetics and very easy to use both manually and remotely. In fact every part of the system except one delivers on the promises it makes. The problem is that system simply cannot handle a duel stage heating system that uses a Heat Pump as a primary means of heating backup up by an auxiliary system such as a furnace. Despite changing several of the options and pre-sets the fact is your Auxiliary heat will be on far more than ever before costing more not less money to heat your house. The support boards are full of people trying to solve the issue, including re-wiring and fooling the system into thinking it’s in a different part of the country (it sets some conditions depending on where in the country it is and what the weather is like).
    The answer I received from Nest was to disconnect certain wires during certain weather conditions….plain stupid.
    The biggest worry is that to date I can see no recognition from Nest that this is an issue at all. Technology always needs debugging but every day that goes by with this product is going to cost you more and more money in heating bills if you have a Heat pump and auxiliary system….be warned.

    The NEST Thermostat and NEST Protect.... the truth.



    I have owned both of these item since they came on the market. I thought they would be good to have to protect our home and allow us to communicate with the items and control our home while away. After owning both of these for some time now this is our experience.



    Our home:

    We live in rural Ontario. We have an all electric home with 200 Amp service and a 15KV generator to supply power when the power goes out. Our ISP provided a Siemens Modem and behind it we have an Apple Extreme 801g/n router to provide wifi. We now also have a UPS to handle the wifi until the generator starts during a power failure. Even in a power failure our ISP provides Internet access.





    The NEST Thermostat:

    It was easy to install and worked right out of the box. It is easy to use in person and controls our electric heating just fine. It was only after a power failure we began to see the issues. The NEST does not like to reconnect to our wifi after a power failure. I have always had to wait until I return home, walk to The NEST and select “wifi” and press it. Then it connects. The NEST is only 3 meters from our wifi router and signal strength is reported to be “excellent” at 86% when tested. So signal is not the issue. To get around this I’ve installed a UPS so the wifi never drops. This has solved this issue it would appear at the moment. No battery issues so far. Other issues: It has no idea where we live. I had to trick it during setup as our location is not available. Occasionally it complains about setup issues that when checked don't exist. On occasion it will not light up when approached even though this feature is turned on. I have to poke it to get it to light up. All else appears OK. Do I trust it for an extended vacation in the winter: NOT ON YOUR LIFE.



    The NEST Protect:

    We purchased 2 of these when they hit the market. Installation was easy and they both worked out of the box. The issues with both of these units are the never-ending stream of false alarms, always when we are away. We rush home to find NOTHING.!! Even while writing this our bedroom NEST Protect went off telling us about smoke in the bedroom that isn't there. We’ve received Emails telling us our bedroom is full of smoke. When we arrive home our cat is sleeping on the bed so we can safely assume the alarm in the house did nothing. We’ve had alarms of power outage when there was none. We’ve had alarms of fire when there was none. THEY ARE A PAIN.



    The NEST Support:

    In a word: it’s non-existent. When you refer to the web site there is a “Contact Us” area but it only takes you to another page which lists HELP and The Community. In other words “You bought it and you’re stuck with it and we don’t want to talk to you to help you with your problems”. If you do leave comments in The Community someone will answer but it’s days later.



    I would in no way recommend either of these products to anyone but I did buy them and yes I’m stuck with them. I may end up dumping them on eBay and going back to Honeywell products that actually do work.

    bought the nest at Christmas in three months it broke

    the technician nest recommended me to use in my area told me he's seen a lot of them break

    do not buy this product
    wish apple did not carry it because I thought apple would have not carried it if it was not reliable
    now I have my old thermostat and everything works well now

    try Honeywell

    if anyone from nest reads this build a more reliable product before releasing

    Don't buy a Nest Thermostat - Low Battery = no wifi

    • Written by from San Francisco

    The Nest Thermostat simply does not work. I have owned and returned 5 Nest thermostats. They look great until low battery notification appears and then no wifi connection. So really no Nest remote functionality. It may look better but internally it is a poor design and doesn't work. I replaced 2 Nest Thermostats, and in less than a month both had low battery problems. Just to be clear, you can not access or change the battery on the Nest thermostat. I am going to try the Honeywell. Have a good day.

    Really wanted these to work

    • Written by from Tipton

    For what it's worth, I'm a software engineer actively working in the "connected devices" world. Point being, I SHOULD have above average technical know-how.

    Summary of installation for TWO thermostats:
    Wiring 20 minutes total - easy
    WiFi config - 40 minutes (really painful - no exaggeration) AND I had to change my router security to mixed mode before it work. I have a 3 year old Cisco router. I've had no problems with any other device in my house and I have probably 12+ "things" connected all of the time.

    Next morning
    - Error displayed on the Nest and my upstairs was at 61 degrees.
    - Nest support ran through some tests and determined my furnace had an issue and I should call my HVAC guy.
    - Just google "N26 No power to G wire detected."
    - This furnace is a heat pump and apparently didn't provide enough power to keep the Nest happy. I replaced my old thermostat and everything was just fine.

    During the next week
    - My Gas force air furnace worked great and the info coming off of the Nest was exactly what I had wanted/expected. ...until it stopped connecting to my WiFi. It was only online for about 5 days total.
    - After a couple of additional attempts I gave up.

    Bottom line: WiFi connectivity is key for this product and both units had general connectivity problems in my house where other devices seem not to. Before installing on a heat bump, do some additional research. You might be better off with a non-programmable anyway.

    Great idea but....

    Bought the 2nd gen Nest. Returned it because it didn't work with Honeywell air cleaner or humidifier.

    When they upgrade again (3rdgen) hopefully these shortcoming will be corrected.

    Give it a try, so long as you can return it.

    • Written by from West Hollywood

    I read a bunch of reviews online here and other websites. People love it or hate it. Mostly because it works for some and not for others. I bought Nest a couple of days ago. The batteries continually die, causing the Nest to shut down and resulting in me having no control over my AC or heat. So for me, it didn't work. When it's on, it looks great. The concept is fantastic and I have friends who have Nest and they have been problem free, which is why I decided to give it a shot.

    It seems the best option is to buy it from Apple or from somewhere you can return it, should it not work for you. Also, only if you can install it yourself. It took me about 20 minutes. So when it didn't work, I spent another 20 minutes disconnecting it. All I lost was the time for the install and removal and two trips to the Apple Store.


    My Nest is completely compatible with my system and when it was on and had power it controlled AC and heat just fine. I do have an RC wire, which is supposed to provide power, but that must not be the case, hence the frequent shutdowns for loss of power.

    I hope this helps clear up the confusion for some people on why there are 5 star reviews and 1 star reviews for the same product.

    Disaster, waste of money and time with totally useless tech support

    • Written by from Chicago

    We bought one and got it to work to run the heating, but couldnt connect to internet. Then as suggested by Nest, we reset, restarted the device and since then it didnt detect the heating. After wasting 2 hours on the phone with tech support, they couldnt solve the problem. We said FINE, we sent the wiring and the picture to Nest compatibility email to get their advice. After a few days we got an email saying it wouldnt work cause we have high voltage which is absolutely wrong. Not sure how to trust such tech support who cannot even diagnose high voltage from low voltage, let alone to help with the rest. I strongly not recommend this product as it is over priced and not working. it just looks fancy and the idea of how it supposed to work is enticing, the reality is it's not working. period!!!

    Thermostat Disconnected

    • Written by from Eureka

    I purchased a house with 2 Nests. Seemed like a great concept, however the unit's constently disconnect from the App. I'm told it's because they lose power and connectivity is the first function that shuts down. What good is a thermostat that you can control remotely that is only connected 15% of the tiime. Not to mention if you change your schedule for the slightest reason the whole concept of a learning thermostat is in the toilet!. If you work from home Iyou'll need to keep telling the unit that "I'm working in the office, stop setting the system to away!!" The only benefit I have gotten is the abitlity to set the system to away when I'm out of town. That is, if it's connected. Check back enough times and I might catch it connected.

    Neat when working...until it doesn't - caution!

    • Written by from Bloomington

    1-year after install the Nest failed.

    Came home on a freezing day to the Air Conditioner being told to run by the thermostat. The Nest could not shut the unit down - on/off = no change - had to turn off the circuit breaker. Their technical support confirmed the base plate had failed and they sent out a new one. The new base plate fixed the issue. Research shows I'm not the only one with this issue.

    This kind of failure can damage property since I live in a state with climate extremes. It's not worth the risk and I'll be getting rid of it.

    You have been warned

    • Written by from Newton

    Went through multiple emails making sure NEST was compatible with my heating system. Had the NEST professionally installed. On the 2nd day it just started blowing cold air. It is 40 degrees outside now and 42 degrees inside and I have to have the old system installed back on. Horrible gimmicky gadget here.

    Has Potential. Needs A lot of Work

    • Written by from Baton Rouge

    I did my research and decided I would try the Nest. I previously used an Ecobee in my last home and loved it, the idea of the Nest using software and algorithms to "Learn" and automatically set to away to save energy seemed amazing. I do not however have a set schedule and after 2 months it is still in learning mode. My girlfriend and I both have the Nest apps on our iPhone, Perhaps if it were to use location to know when we left the house, and when we are going to return... it could help but to my knowledge does not. There have been times when I am in another room and it sets to "auto away" increasing the temperature and making it very uncomfortable. Other times in the middle of the night I will wake up sweating, realizing the Nest decided to raise the temperature 5+ degrees. Aside from that... installation was extremely easy, it looks very nice on my wall, and needs a lot of work from the Nest team.

    Does not work with Carrier

    • Written by from Reston

    I purchased a Nest for my wife for Christmas. Before opening the box, I watched the nest online installation video and went to the nest compatibility website. The website instructed me to take a photo of my existing wiring and send it to nest customer support. I called nest and spoke to a tech after a very short wait. He advised me that my nest "may not be compatible" but had me continue to investigate. After an 18 minute call, he determined that i should go ahead and instal my nest. After installation, my nest said a wire was not installed correctly. I went through troubleshooting and called the support telephone line again. This time they said "because of the proprietary wiring (in the photo i had previously sent) your nest is not compatible." I then went to google and immediately found an article on nest.com that explains Carrier Infinity systems are not compatible. I don't know why the box doesn't say "not compatible with Carrier Infinity Systems" and I don't know why the first phone technician didn't say "not compatible with carrier infinity system."

    Stay with traditional Programmables!

    • Written by

    In theory a great thermostat... that is IF YOU are a predictable person / family. As a retired construction / remodeling business owner, including HVAC, I would NEVER put one in a customer's home WITHOUT advising them of the potential problems with this "engineering marvel". AGAIN, IF you have a VERY regular AND predictable lifestyle, maybe an OK choice, but at the retail price (what the homeowner is charged by most contractors), I'd NOT recommend it! PERIOD! My business operated / grew on by-name-referral BECAUSE the products I installed were top-notch as was our craftsmanship -- "Old Worlde". W e did NOT do bandaid fixes NOR install junk! This item may not be junk, BUT it'll have you wanting to rip it off the wall and throw it out the window or in the fireplace... when you wake up at 3 AM sweating because the STUPID thing has decided no one is home! OR, you'll come home having set it back BEFORE you left for the week... only to come back to find it "had a mind of its own" AND turned the house into a meat locker when no one was home!!! Neither of my HVAC systems have one!!!! As I said, in theory (and design) may be an OK idea, BUT has far too many shortcomings -- PROBLEMS -- to be used in my high-end business. AND by "high-end", I mean QUALITY, NOT ridiculously expensive!!!! Stay with traditional Programmables! They're more dependable & trustworthy, like the KC-135s I flew, that are still in the air, while KC-10s may soon be history (retired USAF)

    AMAZING PRODUCT THAT HAS GONE DOWNHILL IN 7 MONTHS

    • Written by from SODDY DAISY

    I have been a NEST devotee for 3 yrs. We have 2 installed and they worked with amazing performance until about 7 months ago when software upgrades began. Now the app shows OFFLINE randomly, the thermostat is connected through my Airport (all my WIFI stuff is Apple and nearly new) so I have no remote control. Then I have to touch the dial to get it to connect thru the app. What are they thinking?? NEST support has become a little more responsive in the last month, but even after warranty replacements, the two new units act the same. APPLE--you need to pull this product from your stores until NEST PROVES they have fixed these issues. There are HUNDREDS of threads on the NEST community forum, on these reviews, and on public blogs about this horrendous issue. There is no recourse here but to strangle their business. These problems will occur to every one who buys these, it is just a matter of time. Please pull this product until they get this fixed!

    Don't buy!

    • Written by from Toronto

    I owned it for a year and a half without issues. After automatic update on the thermostat, battery gets drained which results in your hvac shutting down. In Canada, it's not a good thing when you have kids and outside temperature is -20 Celsius...
    I contacted Nest who could not troubleshoot and solve the problem . They sent replacement unit for free but had same battery issue. There was no work done on furnace or change on internet router, problem was clearly with the product software update. Save your money and buy product that does not look as nice but WORKS, AND IT IS NOT THE NEST.

    good looking terrible product, made electric bill double~

    • Written by from louisville

    I have tried and tried to get this great looking thing to work, but alas we are putting the old thermostat back on. Frustration, every month with our heating bill out of control, and never able to really regulate the temperature in the house to a comfortable temp. Either freezing or burning up. Randomly turns off after it's turned on for 30 seconds and then comes back on for 5 and then turns off again! Don't waste your hard earned money because it looks so cool! Looks are deceiving.

    Frozen Pipes

    • Written by from Zhangjiagang

    Before starting this review, let me state my credentials. I am a Physics Ph. D, with over 20 years experience in test and measurement, and I also have an electrical engineering degree, dozens of technical publications on testing and simulation algorithms, in addition to law school and being CTO of a tech company. If I have trouble getting this device to be reliable, I'm going to make the claim the device is not reliable.

    I used a Nest thermostat for about 4 months before it failed, causing the pipes in my home to freeze and rupture. The issue is apparently related to the inability of the battery to remain charged when the weather is cold and the thermostat needs to signal the heat to run for long periods of time. There is no fail safe mechanism built into the thermostat makes the device function in a safety mode when the controller dies from the dead battery. I bought a gen II device with some version 3.5 something of the ROM. It had upgraded to version 4.0.1 without my consent when problems began to happen. I was away traveling one day when I noticed the battery was creeping downwards, and there was absolutely nothing I could do remotely to turn the heat on. It eventually went offline for a few days, and then magically reappeared a week later, running the heat for 48 hours to heat the home to the scheduled temperature. What was interesting to me before the failure was in spite of the fact the battery had enough charge, I still could not get the Nest to turn on the heat. After a day the battery died, and I lost contact. I was fortunate to have turned off the water at the home before leaving, but of course it is always impossible to drain the water meter, and the meter froze and ruptured. When the heat resumed by itself without me being there, the basement became wet. Very scary!

    My opinion is this s a great concept, but rushed execution resulting in a device that is not tested in all possible real world situations. It is not a good thermostat to use in environments where it is either so cold or so hot that failure is not acceptable. If you have winters where the temperature falls in the -20 C or cooler range for extended periods of time, do not use a Nest. Buy something with 120 years of proven reliability, like an electromechanical round Honeywell thermostat. It will save you a lot of headaches and cash. If you want to monitor your home temperature remotely, learn to use an arduino and temperature sensors. It will be safer.

    I think Nest ought to start worrying about a class action. I have heard several similar complaints. They might consider proactively addressing this problem.
