    Not so smart afterall

    • Written by from Athy

    Will keep this short -

    Despite having two units replaced and testing with 8 (yes 8) routers these thermostats hate to stay online. They constantly loose their connection to WiFi and cannot be controlled remotely.

    NEST support state that its a known issue etc etc but no fix.

    Advise. Dont buy

    WENT DOWN HILL FAST!! DONT BUY!!!

    • Written by from Covington

    Have had the Nest 2nd Gen since the release date and WAS absolutely amazing. App worked great never and problems. Unit was easy to hook up and is great. Heat is set to 70 the heat will kick on at 69 and shut off when it hits 71, so it's not constantly turning on. You can fine tune the temp to around quarter/ halfs without it saying 70.5 or 70.25. It was great!!!! Amazing!! Best thermostate ever!!!
    THEN I DONT KNOW WHAT HAPPEND, TERMASTATE APP WORKED ONLY A QUARTER OF THE TIME. EITHER WOULD SAY OFFLINE OR YOU WOULD CHANGE THE TEMP, CLOSE THE APP THINKING YOU CHANGED IT AND IT DOESNT CHANGE IT. EXTREMLY FUSTRATING BECAUSE I USE THIS DURING WINTER TIME TO FINE TUNE TEMP UPSTAIRS SO MY TODDLERS DONT OVER HEAT OR FREEZE WHILE IAM UPSAIRS AND I DONT NOITICE IT DIDNT CHANGE UNTILL MY BABY MONITOR ALARM GOES OFF BECAUSE ITS TOO HOT AND I HAVE TO RUSH DOWNSTAIRS TURN IT OFF (HAVE TO TURN THE NEST DAIL AND IT CLICKS BUT DOES NOT REACT UNTILL 10 SEC OF TURNING THE DAIL) THEN GO AND OPEN THERE DOORS TO LET OUT HOT AIR. ALSO UNIT SHOULD TURN ON AND DOES NOT AND I TURN THE DAIL TO GET IT TO SHOW TEMP AND TURN ON AND CLICKS BUT DOES NOT REACT UNTILL 10 SEC LATER AND IT JUMPS 10-20 DEG TO THE SET TEMP. ITS LIKE ITS ON SLEEP MODE OR ITS ALWAYS DOWMLOADING OR UPLOADING AND TURNING THE NEST OFF UNTILL YOU FORCE IT TO TURN ON.
    1 YEAR AGO I WOULD HAVE TOLD YOU BEST TERM EVER AND HAVE TOLD FRIENDS THAT ASKED, NOW I WOULD SAY ONE OF THE WORST TERM EVER. SEEMS LIKE AFTER GOOGLE BOUGHT NEST ITS WENT DOWN HILL FAST. IAM REPLACING MINE SOON AND WILL NEVER GO BACK TO NEST, TOO BAD TOO. WAS GOING TO GET A HAND FULLY OF NEST PROTECTS AND AN UPSTAIRS TERM AND DROP CAMS. NO WAY I WOULD EVEN CONSIDER IT, EVEN IF IT WAS ALL FREE!! I AM NOT EVEN GOING TO SELL MY NEST, I COULDNT DO THAT TO ANYONE. IAM GOING TO TAKE A SLEDGE HAMMER TO IT.
    BY THE WAY HAVE LEFT REVIEWS AND ASKED TO BE CONTACT ABOUT THIS MANY TIMES AND STILL NO CONTACTS OR FIXES. AS I SEE BY OTHER REVIEWS ITS NOT JUST A ISOLATED THING.

    Very Dissapointed

    • Written by from East Falmouth

    The Nest is a real disappointment to us. It simply tries to be too smart and generally gets everything wrong. The advanced functions like "scheduling" and "away from home" never get it right and it is essentially impossible to just set a temperature have the Nest leave it alone. This company obviously has too many computer programmers and not enough human beings. It certainly does not deserve customers. Awful product.

    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.

    Was great. then disaster.

    • Written by from Philadelphia

    Have had Nest installed for over a year. Some wifi connectivity issues, but temp never fell below my preset minimum temp. We just got back to Philly from a two week vacation. We connected to the best when we landed and took off the AWAY setting and set Nest to 70. Get home in two hours and the house was at 41 degrees. Assumed it was the furnace and called for emergency heater repair. Tech proved out that it was the Nest, not the furnace. $280, one new Honeywell thermostat and 10 minutes later heat was back on. Nest log shied activity until 2 days before our return. Luckily, with Philly's high-teens weather it failed during a warm spell and we avoided frozen pipes.
    This has got to be a no-fail product. I'm thinking I bought into the IoT hype too fast. BE VERY AWARE!!

    Big Brother has Control of your THermostat

    • Written by from Holyoke

    I hope you correctly interpret the one star above as a negative assessment. I was forced to click on at least one start before I coudl submit my review. Too bad we could not depict negative stars.
    The NEST product was an interesting and fun gadget for a year and a half ... until control of it was taken away by someone during one of the coldest days of the year. As the house got colder and colder I worked through the NEST website looking for tech support to no avail. Finally Googling "NEST help" got me a contact number. During three hours of troubleshooting I found out that this thermostat was part of an energy savings program. NEST thought the thermostat was controlled by my local utility. I contract my local utility and they had no idea what I was talking about. I then went back to NEST and they still had no idea who was controlling the thermostat or how low the "Controller" whoever that was would let the temp fall. I worked with them a little longer in an attempt to opt out of this energy saving program and after three hours I told them thank you very much, but your time is up. I then replaced this thermostat with a conventional programmable thermostat. The NEST product is not ready for prime time.

    Always "OFFLINE"

    • Written by from Sacramento

    Don't buy the Nest Thermastat if you think you might be using it as a remote device from your smart phone; trust me the Nest does not work remotely haft the time. It's alway "OFFLINE". There is a serious bug in the system and the developer has not addressed the problem.

    Awful for Vacation Home

    • Written by from Philadelphia

    Though this thermostat is very cool looking, and the learning feature interesting, it lacks two basic feature that make it terrible for a vacation home.
    First, it does not have a low temperature alert that emails you when the temperature drops below a certain level. This would give you a chance to try to get ahead of freezing pipes.
    Second there is no temperature hold feature. Sometimes I want to just set a temperature and leave it there... The most basic of functions.
    People have been complaining about these issues for the past couple of years on the Nest boards and the complaints are falling on deaf ears.
    Going to try to sell my 2 nests and get Honeywells.

    AVOID NEST; Coolest look; Inferior functionality

    • Written by from Beverly Hills

    This is a very cool looking, poorly designed thermostat.

    If you are looking for a thermo that is easy to use this is NOT it.

    1. There is no on-off switch; that's basic. I want to turn the effing system off. There is no simple, obvious way to do that. I want to turn the effing fan off. There is no simple, obvious way to do that.
    2. No tech support, except FAQs and the "community." Clearly cheap for apple. Clearly inadequate for a consumer.
    3. Navigating the system is cumbersome, limited, sequential screens.

    Do yourself a favor: Get a Honeywell or some other brand that does not look so cool but that has a good display and can be easily used.

    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)

    Baseplate FET failures are a real and unresolved issue

    • Written by from Livingston

    This thermostat has a high failure rate. Search for nest FET failures online and you'll find multiple hits. The failure rate is significantly higher than reported and the consequences for these failures are significant (damaged or destroyed hvac equipment and extremely high heating or cooling bills). The FET relays in base plate seem to be temperamental and short out very easily or leak. This is particularly true for the y1 line (air conditioning condenser). The result is that the nest turns on hvac equipment without even knowing its done so. There's no way to find this out remotely. Some people seem to believe installing additional relays may solve the problem. I lost a condenser on our vacation home to the nest and my electrical bills were never higher than when I had the nest. I am sticking to thermostats from established companies that know how to handle power surges, leaks and other issues that are common in hvac systems. I've lost enough money already and don't want to experiment any more.

    Looks awesome. Worked Great for 3 months. Then Epic Failure.

    • Written by from Arlington Heights

    After 3 months of impressive performance, my family went away on a three day vacation. On the way back and about an hour away from returning home, we tried to turn the heat up so we could arrive to a warm home. The setting was on "away." When we tried to turn the heat up, we got a message saying that the last time the unit was "on line" was two days ago. We were disappointed that we could not warm up the house but that was the least our problems. After assuring my wife that the Nest would just maintain the preset "Away" temperature, we were shocked to arrive at a house that was 43 degrees F ! The weekend had been cold. It never got above 20 degrees and the over night temperatures were in the single digits...I have a separate thermometer in the house that records low and hi temps as well as the current temp and I confirmed the house had gotten as cold as 34 degrees! Half of our houseplants looked dead and our upstairs bathroom had frozen pipes! Nest support was responsive once the 20 minute wait to get to a live person was experienced. After several trouble shooting recommendations, we were able to get our heat working by tricking the Nest into believing the AC was the heat source. So the problem was our base. Nest promised to send us a new one immediately but seriously, this product, while nearly there in terms of functionality, design, and ease of use; is not ready for prime time. A device this importance needs redundancy protections built in. IT CANNOT change settings preset by the owner. END OF STORY. No excuses please. Make a device more reliable, not less reliable, that the unit being replaced. It took more than 12 hours to heat our home back to a normal temperature. Imagine if we had been gone for a week or more???? This was a horrible experience I don't wish on anyone. I reinstalled the old thermostat. Bummer but at least it works.

    Don't bother with this product

    • Written by from Dallas

    The good things - nice design, looks cool, easy to use, common sense user interface.

    Now for the bad things. It does not work! Nest has replaced my thermostat one time. The issues are with its ability to be a smart thermostat. It is not. The away function does not work. While Nest will tell you the software only kicks in during the daytime hours, it decides if you are away at all hours of the day or night. For example, at 6PM, it decides that I am away even though it turned on when I came home. It will also go into away mode every hour or so during the evening. So, if you change the temp at 8PM, by 8:30 it will reset to the temp for away mode. And, every morning when you wake it is in away mode.

    To solve that, I decided to use the "schedule" mode. That does not work either. If you only set a single temp and never touch it again, it works fine. If, however, you ever push the temp up or down slightly, it remembers that and constantly resets itself to the new temp. I can't recall the number of times it resets to 65 in the AM, or resets at other times on its own. It takes several times of over riding the temp to get it to reschedule the right temp.

    Quite simply, this smart thermostat is stupid. I would avoid all their products. While the shifting temp is an inconvenience, I would not trust their smoke or CO detectors.
