Reviews for Nest Learning Thermostat 2nd Generation

This product is truly amazing. I had a little trouble getting it to work with my system but the nest help center walked me through it on the phone. I would recommend it to everyone.

I've had my Nest thermostat since December 2011, and have been very pleased with the results. Also, glad to see that even though new version came out - I still get same software updates and functionality. 2 neighbors have since bought one also.

Have three 1st gen units since last December and they just work together. They may cost a bit more but here in PA I saved over $300 just this summer on our cooling costs and came out of last winter with a credit to our nat gas heating cost. The Airwave feature alone makes you wonder what took so long for this feature to come out of the industry. One nice thing is that these units get a software update once released automatically. I feature I wish it had was the ability to just turn on the fan without turning on heating or cooling.

Like others stated pretty straight forward to install just make sure your system is compatible. The app makes it easy to control while away. In the past while on summer vacation I had someone come in and turn the AC so the house would be cool once back but this year I was able to take it down from 80 degrees in steps rather then all at once.

Nest is a GREAT start! Here's how it could be even better.

Missing features:
-Outside temp displayed on screen.
-Forecast (hourly and or weekly) displayed on screen.
-Integrated usage of hourly temp web predictions to anticipate whether or not it needs to heat or cool or if it can just wait for the home temperature to adjust naturally. Why do I want my thermostat to cool my house 1 hour before the temp is predicted to drop? Nest has access to this data via WiFi.
-Phone app GPS to learn when I'm away and when I'm headed home.
-Developer app support (3rd party app development). I don't need to play Angry Birds on my thermostat but I would like to learn what a community of developers would dream up. I'd buy a cool app or two.
-Centralized NEST hosted forum for feature suggestions and bug troubleshooting.
-Monthly usage summary that suggests slight reprogramming changes that could maximize efficiency and instant implementation if user confirms.

This product is amazing! You can control your thermostat from wherever you are whenever you are. Don't worry if you've been gone for 2 weeks and you think all the air conditioning has gone to waste and will cost you a ton of money because with the Nest you can put it to a certain setting so that it will save you energy and money.

I had a two wire thermostat, gas fired furnace installation.
While the instructions state that this type of installation is straight forward and will work, it quickly became apparent that this is not the case.
The unit has an internal re-chargeable battery that charges itself while the heating circuit is closed and the furnace is running when in used a two-wire thermostat system. The problem with this is that the heating system may not be active for a long enough time to fully charge this battery.
This was the case in our installation and it was not long (about 10 hours after installation) before the battery was discharged to the point where the Nest would not function.
To ensure that the battery does charge on a regular basis I ran a third wire from the thermostat to the furnace and connected this to the continuous low-voltage supply at the furnace thermostat wiring panel. This wire is referred to as a "C" wire and the "C" terminal on our furnace wiring panel was clearly marked with a "C" making it easy to complete this installation on my own. Having done this I have had no problems with the unit and it works exactly as promised in all of the literature.
The "self learning" function works great and the ability to activate and control the Nest from wherever I have an internet connection and my iPhone or iPad is outstanding.
We have been using the Nest for over one month now, during a particularly cold period, and can already see a difference in our overall power consumption. While this may be due to any number of other factors I feel that this product has contributed.

This Thermostat is beyond anything that I have seen. It has already saved me money on my heating for this winter. I would recommend it to any to buy!

This thing is incredible. The future of affordable smart homes is here and make this your first step into it. The guy who created this helped to create the original iPod, so you know that this is top notch gear. 10 minutes to hook up, 5 minutes to set up online account.

I recently upgraded my upstairs and downstairs HVAC units. I also installed 2 Nest thermostats. The devices are truly amazing. Rather than adapt to some old paradigm of programming a device these devices adapt and learn from your habits and schedule. In a few days I could not imagine going back to a conventional programmable thermostat. Easy to install and get running. It may be more difficult for me to determine energy savings since I replaced my HVAC units. But having a device adapt to you rather than you adapt to it is great. Revolutionary just as the iPhone was. Highly recommended.

I loved the idea of this thermostat so much, I bought two. The first hurdle was installation. I chose a professional installation through Nest, but after 3 failed attempts to schedule "local" installers on their list. I gave up. It seems that the contracted installers have a certain mileage limit they commit to as Nest Certified Installers, but won't actually travel more than 20 miles or cross State lines to do a job. At least that's the way it is where I live. Nest would schedule and the contractor would call me directly and tell me they couldn't do the job and I should call Nest to find another installer.

So, I lost two days of work dealing with that hot mess. Nest was kind enough to refund the install fee and my local Heating guy took the amount I was quoted by Nest. So, it was a Win/Win except for having to burn two days of vacation. The install was a breeze for the Heating Company tech. He had one in his home and one in his vacation home. He had nothing but good things to say.

The last six weeks have been great. I've been watching energy savings rack up on the iOS App by setting my heat to a 50 dgree low while away 5 days per week. In fact a friend just asked me today how I liked the T-stat. I raved about it and he plans to buy one tomorrow. Then I got home.

The entire upstairs was cold, it's 18 degrees outside and snowing on a Friday night. My upstairs Nest was showing an error E30. One of the wires was not giving power. If there is one thing I have learned in my 40+ years, it's that the wire itself is hardly ever the problem. The problem is usually at the origin or the termination point. So, I fired up tech support on the Nest site, got a case number and called the tech support line. Two hours later, many wire swaps, power cycles, trips to the fuse box and transfers of support personell. I was left with a choice between shorting the wires so that my Oil Burner runs continuosly costing ooodles of cash or sleeping on the couch and hoping the upstairs pipes don't freeze. The Nest tech thinks it's the Tstat base. It's Friday, my new Nest arrives on Tuesday. Really? This product may not be ready for prime time.
