    Unstable

    • Written by from Uxbridge

    I normally don't write reviews but this product is so unstable it desires one. After owning my device now for over a year, I can tell you that my device is rarely online, Nest customer support is not helpful and my hydro/heating bills have actually increased from using this product.

    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.

    DON'T BOTHER WITH NEST

    • Written by from East Greenwich

    The Nest thermostat looks sleek. Unfortunately it doesn't do what it should. After about 8 calls to Nest (always very pleasant advisers), my thermostat still goes "Offline" without explanation. This means that I cannot control the temperature remotely, which is the whole point of the thing. Save your money and by a much cheaper one at Home Depot.

    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.

    Nest is UNRELIABLE

    • Written by from Hauppauge

    STAY AWAY from this product if you intend to use in a weekend house, or any home that isn't occupied everyday. IT is unreliable. The battery keeps going dead. The patches they've sent to fix are worthless. do NOT buy this product. It is TOO unreliable.

    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.

    Nest, Not what us used to be...

    • Written by from Oakdale

    I purchased my Nest 1st generation 5 years ago, and it 'was' a phenomenal piece of equipment. It managed my heat pump, heating and cooling requirements better than my old mercury driven thermostat... The Nest DID save me money on my electric bill. However, Nest must have recently had an update to their device which I'm finding 'I cannot manage my FAN air function.' During the daylight hours when my system is demanding AC, Nest operates as it should by providing AC. In the evenings when it's too cool for AC and still too warm for HEAT, my FAN does not turn off... It constantly runs even after I manually command Nest to 'OFF.' I find I need to manually turn the AC, HEAT PUMP unit to OFF to force the fan yo stop operating. Hence, I'm no longer saving money on electric/heating bill. Note: For some strange reason, this issue is only a problem during the evening hours. I'm considering removing my Nest and replacing it with one b their competitors.

    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.

    Great product, but don't upgrade yet, especially if you live in the South

    • Written by from SLIDELL

    Have had my nest almost a year. Installed it the end of last summer. Love all its features except 2:

    The first is the way it plugs into the wall. It is very easy for family members to knock it off the wall while trying to set it. It is better set from your iPhone. This would not be an issue if people were not playing with it so much do to the main issue in the next paragraph.


    The main issue with the Nest is the lack of ability to control humidity settings. My old thermostat allowed this. I have discovered that living in the South, this is a very important feature for comfort.

    When the nest turns on to cool the house, the humid cold air is annoyingly uncomfortable. Turning up the ambient room temperature to correct this results in a room that feels to warm after the AC stops blowing. So either you feel a little too cool when the AC is blowing, or a little too warm when it's not. This is not extreme, but just enough to be annoying if you spend time in your house. I don't notice it when I return form work and go to bed, but I do notice it on weekends and days off when I spend time in the house this summer.

    I am well past the learning curve for a new device, and have not solved this, but I do see where the Nest measures the humidity. So it should be possible for the company to allow us to control it.

    Since a basic wired thermostat has a humidity control feature, I am surprised that Nest does not. If I was not so lazy, I would re install my old thermostat. If Nest solves this problem, I will upgrade.

    Not worth the money

    • Written by from Sandy Springs

    First - Nest lacks the most basic of thermostat functions: Hold Temp. Enthusiasts will tell you the Nest features eliminate the need for it, but Friday was a holiday and there was no way to tell the thing not to run the usual weekday program.

    Second - Auto Schedule makes random unexpected changes. The ability to confirm those changes would be great. My thermostat decided that I didn't want the temp to drop to 70 degrees at 10 PM anymore and cleared that part of the program even though if I made that adjustment, I only did it once. So Auto Schedule is off.

    Third - Auto Away overrides the schedule. So rather than having a comfortable temp in the house when I get home from work, like the program is set for, the thermostat goes to Away when I am at work and I have to interact with it to get it to run the program. What is the point of a schedule if the thermostat doesn't follow it? So Auto Away is off.

    The novelty features of Nest don't really work. I'm pretty sure that the thermostat is not smarter than I am, but it thinks it is and does things it thinks I want. I shouldn't have to interact with my thermostat regularly to get it to do what I want it to, but that is what the Nest requires.

    There are less expensive wifi connected thermostats that do what the Nest does. They don't have the fancy metal ring around them, but that is about all you are getting for the extra money. I wouldn't buy another one.

    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.

    Great in theory- terrible in reality

    • Written by from New York

    If you are soul owners of a home and have no guests- nest rocks. Otherwise think twice. First thing is anyone over the age of 50 or isn't totally mac savy won't know how the heck to operate it and you'll be graced by crazy energy bills because guests self adjust the settings without you knowing- fun times:) That's what it comes down to, if you have guests in your home, and live in your home with a constant stream of friends and family- this system is not realistic and will end up quadrupling your energy bill.

    Great Design, horrible product with major issues

    • Written by from Riverside

    The Nest has the beauty of Apple design but poor quality product

    The product installs easily and support is good

    After running fine for a couple months I came home to both my furnace and air conditioner running at the same time. This was for three days and house was 90 degrees. The energy costs alone are greater than any potential savings. The danger factor alone for this known problem is high and I can't believe they don't recall the product.

    I received no alerts or anything on the iphone app. It only pretends to be intelligent for minor features. It is has little intelligence for reliably heating and cooling your house which is the main job.

    I went back to a $25 Honeywell thermostat from Home Depot and everything is fine. Nest will replace unit but how could you trust the device.

    Can't hold comfortable setting

    • Written by from Bothell

    It looks good and the remote interface isn't bad but, but it allows the temperature to swing almost 2 degrees in either direction of the set temperature. This leaves you feeling too hot or too cold most of the time. It also make the set and forget ability of a programmable thermostat useless because you have to constantly adjust it. Going back to my ugly, no remote interface Honeywell.

    Motherboard Chatter Causes Problems

    • Written by from Calgary

    We own a three-year-old York furnace. I installed the Nest thermostat before winter. Throughout the winter we had several problems with the furnace – we had to replace the motherboard twice, fan and other repairs. The technician finally diagnosed that the Nest kept making calls to the furnace turning it on and off (chatter). We have since replaced the Nest with a regular thermostat and have experienced no problems. This was a very expensive experiment. Cool product, but does not appear to be ready for mainstream …

    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.

    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.

    Check the type of system you have before buying

    • Written by from Toronto

    I am the owner of a 1st generation Nest Thermostat. It worked amazing with my old single stage mid-efficiency furnace. The furnace quit last week and I replaced my furnace with a 95 percent high-efficiency furnace with a dual staged fan. Nest thermostats (1st & 2nd generation are not compatible with furnaces with multiple stage fans - as per Nest Technical Support. I had to revert to using my old programmable thermostat and I am now the owner of a $250 hockey puck.

    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.
