    Triggering in high humidity

    • Written by from Toronto

    Owned the Nest fire alarm , it trigged two false alarms in three months both of them when the humidity was high. Alarm kept sounding only stopped when I moved the alarm in an area in the house that wasn't subjected to the high humidity.

    Can't find customer support to figure out how to correct this situation

    Want to love it but can't

    • Written by from Long Island city

    I was the biggest advocate of this product but less than 2 years and two replacements and I am done. This is just not durable and is costing me a fortune having to call technicians to fix it.

    I own 4 of these

    • Written by from Huntsville

    I currently own 4 Nest Thermostats gen. 2 that are connected to 4 brand new American Standard Hvac units. Two Hvac units have been unusable due to faulty nest bases. Nest is aware these bases can be a major problem for some customers. So the fix is, send out the new and improved base that works. Why not send those out ahead of time before I am left in the dead of the winter with no heat in my child’s room (blaming my local Hvac guys for my loss of heat). Or in the summer time and the AC will not turn on (blaming my local Hvac guys for my loss of AC). After I installed the second base, I asked Nest to go ahead and send me two more new bases for my other two thermostats that have not been upgraded yet. Nest has refused my request. This along with the nine Nest Protects I own (I have had problems with too with no real solution from Nest) have been more hours of phone calls, troubleshooting and stress that Nest as a company could fix very easily. A company who wants to sell the most expensive Thermostats and Smoked detectors should really set the bar a little higher than this.

    Love our Nest

    • Written by from Newberg

    We've had our Nest for more than two years now, and have had very few issues. Our house is only 4 years old, and installation took 15 minutes.

    The largest issue we've had is intermittent connectivity issues, which seemed to be resolved once I dug up my older WIFI router and created a dedicated network for only the Nest devices. Since I did that early on, we've had very near 100% uptime since.

    It paid for itself in lower energy bills in less than a year. YMMV. The latest app revision is excellent, and we couldn't be happier with our Nest.

    OK product, declining company

    • Written by from Los Angeles

    My Nest unit just suddenly stopped working after a year and the company couldn't explain why -- I replaced it with a Honeywll WiFi which has been fantastic and reliable.

    Also, I found the Nest didn't actually learn anything at all -- it just did whatever program I set for it, which makes sense. You don't want your thermostat changing its programming on its own. But it's certainly cool to look at.

    I also got the Nest Protect, which was a disaster for the company -- they had to turn off some of the advertised features, and it was impossible to turn off the alarm for some people (search Nest Protect buggy product for some hilarious videos).

    Now Google owns Nest and Dropcam (they just tripled the price of Dropcam's DVR service), and I don't like the idea of Google being able to view and control my home, so I'm moving onto other home automation solutions.

    Love my Nest

    • Written by from Surrey

    I have now had my Nest for a couple years. Has never failed me, always working as intended. The app is even better now and loving it. I'm not on it all the time, but when I need to make adjustments or just check to see humidity and temp its at my finger tips. I use it more often when I go to bed when I've forgotten to turn the heat down!! A great investment for our home!

    3,000 Miles Away

    • Written by from San Jose

    I am currently 3000 miles from home, heading back to California today. The weather had changed dramatically since we left five days ago. Just switched my Nest from heating to cooling so the house will be comfortable when we arrive home tonight. This is Nest's best feature, being able to control it remotely from my iPhone!

    Beware of these "thermostats"....

    • Written by from Gurnee

    I had 2 of these installed for just over a year and a half. Numerous back plate failures and added repair costs forced me to remove these and find an alternative. (Ecobee) My HVAC equipment is the most basic and common- single stage, forced air heat and AC. I do have the notorious "C" wire for powering these units. Since the firmware update in Nov. 2014, they went offline much more often, which defeats the purpose of these when controlling remotely. If you're considering, do extensive research regarding failed FET backplates and the offline issues. $1500 spent for me that I'll never recover. Beware!

    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.

    Guess what?? It's offline again.

    • Written by from Riverside

    We have two of these thermostats in our home. They take turns each day going offline. When you physically go into the settings of the offline thermostat, it shows it's connected to the wifi network with full signal. The eight Nest Protects we have never have an issue with wifi connectivity.

    Offline Daily

    • Written by from SAN PEDRO

    My Gen 1 Nest worked like a champ. My Gen 2 Nest is offline more than it's online. It's at the point that the only reliable way to control it is manually. The pretty much negates the reason for owning it. Nest customer service is polite, in fact I've never felt better while being blamed for a problem. My Nest Protect seems to work just fine so it can't be my wireless network, a fact that seems beyond the comprehension of the tech reps I've spoken to.

    Definitely looking into alternatives at this point. I'm rating it two stars only because it looks neat.

    Keeps going off line in both homes

    • Written by from Hudson

    Have a Next Thermostat in two homes and both keep going offline. Someone has to be at the thermostat to get a reconnect code so this is not really a remote Thermostat. Over $500 shot.

    This thing use to WORK

    • Written by from Townsend

    This product was great 2 years ago and all of the sudden in October 2014 it stopped working. It would go off-line and I would be unable to control the temperature in the home. The customer support was great but they never help me fix the problem. I'm sorry to say I got rid of my nest

    Avoid At All Costs!

    • Written by from LEAWOOD

    I am constantly having thermostat going offline with my 2 Nests. It didn't start until the last software update. Been using the same Airport Extreme both before and after the SW update. Nest is taking way too long to get this fixed. This makes the iPhone app useless since it can't talk to the Nest. Also, no HomeKit or Geofencing support. Once a great product now marginalized. I wish Apple would have bought Nest instead.

    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!!

    Always going OFFLINE

    • Written by from HOLLAND

    I would rate this stat a 4 star if it was not going OFFLINE all the time.

    I have 8 of the Nest thermostats. They worked fine for the 1st year and a half. Then after a firmware update to 4.3.3 , sometime in November 2014, they all went intermittently OFFLINE. Typically not all at the same time. I've had as many as 6 at the same time being this way. I got with support, which took a while to get to an engineering level person, and after going thru some stuff with my network they admit that there is a problem with their firmware but as of yet no update was released.
    This was about 5 weeks ago.

    I really like the stat. It seems to regulate fine but the problem is using an app or computer browser that it shows the stats OFFLINE and can't communicate with it. It might be in this state for 5 minutes or 25 minutes. Eventually it comes back ONLINE.

    I'm in a holding pattern now but if not fixed soon I'll go to another brand thermostat.

    I have had this thermostat for over one year. Nest has replaced it once but still a problem going offline. Every wi-fi device I have stays on line but the nest stays off line a good part of the time. it is a real problem when I am out of town and need to turn it on when I get home.. I would shop around !

    Great Solid Product

    • Written by from Plymouth

    Been using the Nest thermostat and Nest Protect's for a few years and no huge complaints. I've never had any significant issues with the thermostat except for a few software issues that were quickly remedied by updates. Im not sure what issues the other reviewers have had with significant temp drops, since its set up with auto temps and a safety feature that will turn the heat on if it gets under a certain temp. I had the 'Offline' issue but that was fixed with some network troubleshooting. I can definitely see how it saves me money on oil as we've used much less oil in the past two years having the Nest. My only complaint is the difficulty getting support on their website. Since theres no live support or email support, you have to call them, which when I work during the day of their support hours, It can make it difficult. But as far as the hardware itself, its fantastic. Has more than paid for itself.

    Holy smokes what is with this product?

    • Written by from Sherwood Park

    we bought this thermostat to save a bit of energy but come on! You can't control the temperature, it seems to do its own thing and won't let you override it. I woke up to a house in Canada in the dead of winter at 16 Celsius! My dog was about ready to pack his bags and leave it was so cold! Listen in theory this product is amazing but it's not a good product, I'd worry leaving this guy on when I was on holidays! It randomly turns my furnace on and off and it's not efficient in the least. Stay away until they work out the bugs!

    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
