Bought thermostat 68 days ago and it has already failed! Oh, the warranty replacement will be a REFURBISHED unit -- which brings a whole host of new issues.

the 3rd generation goes offline .3 times in 3 weeks

Every 2-3 days I have to restart it because it stops working. It seems like there is a bug in the code

There's no batteries in the thermostat. It constantly cycles the thermostat because it doesn't get enough power. If you have to take it off the wall the charge the thermostat. I'd rather just have a basic thermostat at that point. The features are ok other than that. HUGE COMPLIANT! It's a pain when the weather is cold and you have to charge it otherwise your house could freeze!

We're currently on our 3rd nest. First one stopped connecting to the internet. Second one also stopped connecting to the internet but also wouldn't charge. We were left without a thermostat in our house for days so no heat. We just got our 3rd one yesterday and I just want to make sure no one has to deal with this. Everyone around me with them have had the same issues.

I've regretted buying this thing from almost day 1. It repeatedly changes my temperature on its own, all the time. I'll set it on 74, only to find it blasting cold air at 69 a few minutes later. I've tried turning off all the atrocious "learning" features, but even then it still does it. I'm at the point where I'm close to ripping the thing off the wall and getting a normal thermostat because I'm so sick of it changing the temperature to random nonsense on a daily basis.

I would not purchase this product again. After 8 months the product would no longer connect to WiFi. After 3 hours on the phone with google/nest support, they sent a replacement which I received in about 2 weeks. 6 months later (now out of warranty) the same problem occurred. After speaking with nest, they told me I should just buy a new one. Because the third time is the charm I guess? Don’t waste your time. Buy a simple thermostat.

Lack of HomeKit / Apple Environment Compatibility. Temperature shows 76 but all my other temperature sensors agree the temperature is in fact 69 in my house, which makes this inaccurate and useless. Not a product I would recommend to a friend. It’s the prietest with the best UI out there but fails at both main aspects and features it offers, temperature and smart home.

I have 2 in my house bought less than a year ago one of them completely stopped working and one no longer connects to WI-FI both under warranty, I submitted a claim weeks ago and no response Google doesn’t care they just one you to spend more more on these pieces of junk

The battery life very bad. I recplaced it once and I am not Happy with this product.

Have been through 3 of these in the last 2 years. Each time we get the same malfunction error and have to replace. If I could give no stars I would. It always malfunctioned when the weather hit negative temperatures. I wouldn’t recommend Nest if you want it to last more than a year.

Nothing ever works right. Never integrated properly with Google Home or Alexa. Doesn’t work with Apple HomeKit at all. There’s always a problem.

As an installer for these i would not recommend these some models require the google nest home app to run the issue is that this application isnt good it does not work half of the time nor is there an update that fixes the constant crashes. Spare yourself the headache and just buy something that isnt google or nest.

I did my research on smart thermostats and we decided on the Nest Thermostat. It was easy to install and set up, but it will not stay connected to the internet. At first glance this may not be a big deal, but when we leave for work and the nest registers this, it goes into eco mode and turns off the heat or a/c. If it stayed connected to the internet I would like to be able to turn the heat or a/c on so that the house is a normal temperature when we arrive home. We have spent countless hours on the phone with nest and no one has really been able to help us.

I have now gone through two of these and both times the Wifi connectivity has failed with a w5 error code. The Google website says to reset the thermostat if that code appears but that did nothing. The initial experience is great, but product will not last. Buyer beware!

I hate nest. No matter if you disable the learning and disable the away detect it always makes your house too hot. I've even set the temp manually in the program to be 69 max and it always turns it back up. You cannot set the away temp below 75 which just totally sucks. I know this sounds strange but I want to be able to control the temperature of my house... If you are trying to save energy this is probably a great thermostat for you but if you don't care about saving energy and want to be comfortable there is no way to make this thing work.

These were great until they died. Right around the 6-month mark, one of our thermostats lost Wifi connectivity. I have spoken to 5 support reps and received authorization to replace the device, but still cannot get Nest to ship out a replacement. The Google/Nest support experience is absolutely horrendous. These devices are great while they work, but as soon as you have issues, be prepared for a serious support headache.

This was literally the biggest waste of money i ever purchased!!! It randomly turns off and on, will turn on the AC and not the fan, I have spent hours on customer service and the answer usually being, well, we don't know, and when I had an actual AC repair company come out, they told me the Nest was the problem. This thing has cost me hundred of dollars in wasted electricity. Do yourself a favors, avoid it at ALL costs.

Your better off with a standard thermostat. This stupid thing makes my house too cold or too hot. I set the heating to 67 degrees, it won’t turn on until 65 degrees (its freaking cold) then when it finally turns on it heats to 69 degrees (Waaay too freaking hot to sleep it wakes us up) so I’m constantly turning the temperature up and down when it’s supposed to be doing it for you. It sucks dont buy it, I’ve had this too long to return it. Now I’m stuck with this expensive p0s thermostat.

This thing is such a piece of crap. It's complicated, and HVAC personnel don't like it when coming to fix the thermostat. The Google technicians are generally not knowledgeable and don't know their own system when you call them up, which makes no sense. Not recommended.
