Customer Ratings & Reviews

Great product, very sleek and easy to use with our home automation system

Should you buy this? 
 YES: 
if you want a newer styling, 
If you want a larger display with futuristic appearance, and no large bezel occupying a lot of the face. 
If you are willing to pay a premium over prior models, for the addition of an included remote temperature sensor (previously available only as an accessory at additional cost) and the potential of Google AI rolling out improvements over the years for more features and capacities. 
If you have a robust system, with heating/cooling/ventilation and perhaps newer products such as heat pumps and devices that are triggered by external air quality or humidity. NO: If you already own an earlier generation Nest thermostat, and are pleased with its performance. There are no major new functionalities or features with this new generation, which is the first upgrade since 2015. A thermostat is pretty much a one trick pony, but there are nuances.
 If you prefer the classic Nest app. This generation requires the use of Google Home app for remote control of the thermostat. If you have older Nest products, you might be using two apps to control virtually identical products. However, voice control through a Google speaker/hub will control both equally well.

 Thinking back over my years of using Nest Learning Thermostats, first with Gen 1 and then upgrading to Gen 3 about 3 years ago, once we set the daily settings for desired temperatures through the days of the week and times we were home versus at work, we really didn't change the settings much at all. Honestly the only adjustment I would make would be occasionally to turn on the “Eco” mode. You would manually activate Eco mode either at home or via the Nest app from afar. This mode would drop your heat to a pre-chosen minimum temperature. For example, going on vacation, we would turn the heat down to 52 degrees. After spending a week away, upon our return, I would use my mobile phone to cancel Eco, as we landed at the airport. Then upon arriving home, it had warmed up from the energy-saving lower temp that it had been for the time while away. The Gen 4 Learning Thermostat appears to be more style than substance in its changes. Certainly the new device has a much sleeker, almost futuristic appearance; it seems to float off the wall.The gold tone is quite modern and goes well with the drawer and cabinet pulls in the kitchen where the thermostat is mounted. The display is larger, having lost the 1 cm bezel around the display edge. The packaging was nicely conceived without any plastic; all recyclable. The Gen 4, like many recent Google hardware products, has incorporated Matter into its hardware. So theoretically it can be voice controlled by not just Google devices, but also Apple’s Siri, Amazon’s Alexa, Samsung’s Smart Things devices, etc. Installation was quite easy; it took about 10 minutes. Having a Gen 3, the holes in the wall were already in place. The backplate was a different shape, so some paint touch up of the wall will be needed. The mounting plate screwed to the wall is a smaller size and has 2 additional wires, so you cannot just click the Gen 4 onto a Gen 3 wall plate. But the screw holes were identically spaced, so no new holes needed to be drilled. Quoting the Google web page here, the 2 extra ports on the mounting plate are needed “to work with humidifier, dehumidifier, and ventilation systems - expanding compatibility. If you have a ventilation system, you can use Smart Ventilation, which helps bring in air if temperatures are mild and outdoor air quality is healthy. If outdoor air quality is unhealthy, the system will pause bringing in outdoor air”. Our home does not have integral humidifier/dehumidifier or a separate ventilation system. We use the ancient method of opening some windows. The basement has a separate dehumidifier, quite necessary in New England basements in the summer to keep the musty mold in check. The Nest Thermostat is capable of handling a broad array of different heating/cooling systems, which you select through the set up process in the app. Our simple system is winter heat only, via natural gas. No GeoThermal or heat pumps to integrate. Since I am writing this in August, we are months away from actually turning the Nest thermostat on. For control and management via your cell phone, the Gen 4 does not use the Nest app, and must be activated by the Google Home app. So now, with one Gen 3 and one Gen 4, I have to use separate apps to control the devices individually. To add the thermostat to the GH app, you use the + sign to add a device. 
Then you are presented with 3 choices: 1) a Matter-enabled device, 2) a Google Nest device, or 3) a “Works with Google Home” device. 
I was in a bit of quandary as to whether I should choose choice 1 or 2, as both were true about the thermostat.
It seems either choice could work, and I chose NOT to set it up as a Matter device, not just yet. Adding the thermostat to Apple’s HomeKit app, as a Matter compliant device, was quite easy. This could well have been related to the fact that I am a user of the Starling Hub, which is a wonderful enabler of Nest products for use in an Apple centric home. Now I can control both thermostats with Siri, using voice via your device of choice: Home Pod, iPhone, AppleWatch, or Macintosh computer. The Matter enabled choices in the Apple HomeKit app, however, seem somewhat limited: turn the heat or A/C on/off, set a temperature, control the use of the remote temp sensor (see below), and that’s about it. So not a robust skill set, but really all the major fundamentals. Indoor humidity, ventilation systems, and scheduling are not available via the Matter control on HomeKit; so for fine tuning you need the Google Home app. Google states that Gemini AI will learn your heating/cooling preferences and make automatic fine tuning of the settings to optimize your comfort, lessen your energy usage and therefore utility costs, and integrate your presence in the home to know when you are home and when the home is vacant. So no more manual setting of the Eco mode; the AI knows when you are not home. Your presence is determined by motion sensors is various Google/Nest products: smoke alarms, motion detection in Home Hub Max, in home surveillance cameras with motion detectors, etc. Once the system notes that no one is home, Eco mode automatically switches on, rather than it being something the owner needs to activate. Similarly it switches off from Eco when you return (although returning to a cold house). All the prior thermostats were billed as Learning Thermostat with the sole exception of the introduction of the Google Nest Thermostat (notice the absence of the word Learning). The learning capacity really served as a functional AI algorithm, and is built into 23 years of Nest Learning Thermostat’s history. Perhaps there will be new, more robust features as AI unfolds. But the history of the Nest Thermostat has been really that the features that exist when you buy it, are all you should expect for as long as you own it. There is not a previous heritage of firmware updates or system upgrades of installed devices being rolled out to owners. In checking my installed Gen 3 Nest thermostat, it was last updated May 2022, 2 years 3 months ago. By my recollection that was about when I bought it. So no software updates, firmware changes, or new features added in that time. I have not had any personal experience with other brands of smart thermostats, so cannot speak to deficiencies or benefits of one brand over another. I would direct such concerns to reviews from third party sources. With this unit, you can choose between different faces that appear upon close proximity to the device, so called Near Sight: time display, a clock face, current weather outside, or reading of indoor temp and humidity. Again style tweaks, but not a major function improvement. The other new hardware, included in the box, is the Nest Temperature Sensor (2nd gen). It is essentially the same as the 1st gen, just redesigned to better match the Gen 4’s appearance. It looks like a smoothed stone found on the beach, and can be hung from the wall or placed onto a shelf or piece of furniture. Its primary job is to feed a remote room's temperature to the thermostat for altering the house's heat depending on which room you tend to be in during that time of the day. Of course, given the zones your heating system has, it cannot control one room separately from an adjacent room, you just get to select which room is calling the shots at which time.
 Google/Nest also has an optional program called Nest Renew; to support customers who are concerned about climate change and the role of home heating/cooling in the deteriorating climate. I signed up for that program when it rolled out about a year or two ago. 
As stated in the Google web page: “Once you enroll in Nest Renew, your thermostat can automatically make small adjustments that shift energy use to cleaner and less expensive times. These adjustments are small but add up — contributing to a more reliable and efficient energy grid while lowering household energy bills at the same time.” 
I check in the web page of nestrenew.google.com regularly and it gives me a local feed as to whether I should hold off on running the dishwasher (for example) right now, and instead run it later when the electricity generation is less utilizing fossil fuels. So in summary, it is a time tested, reliable product. It is not the cheapest smart thermostat, and most of the functions are available in models from other manufacturers. But the styling is striking, and the promise of future updates and features from Gemini AI integration are tantalizing, but cannot be guaranteed to develop.

Easy to use and looks very sleek on the wall. Did not have issues installing.

Google-Nest has released their newest thermostat for 2024 after initially releasing their first smart thermostat back in 2011. Google-Nest really set the bar with their design and the intuitiveness of their app. Since then, many other manufacturers were able to gain popularity. Fast forward to now, it looks like Google has primed the Nest 4th Gen to take back the crown. Testing all the features couldn’t have come at a better time as I just replaced by whole ac system. I wanted to see if it would be worth the upgrade from the 3rd gen Nest thermostat. Design First of all, the new Nest 4th gen thermostat is a pleasure to look at. My kids have caught me staring in awe of the elegant design of the device. I’ve owned the 1st and 3rd gen of the Nest learning thermostat, and this is by far my favorite. It’s still pretty early as I have not had the device long enough to test for all the bugs and shortcoming just yet. I’ve had two brand new 3rd gen Nest thermostats fail on me, so I may be best suited to review the newest entry with the years of experience I’ve had with the Nest thermostat. Hardware and install I was able to use the existing screws and the existing placement of my 3rd gen Nest Thermostat. I was able to remove the existing and setup within 15 minutes. I love the fact that I was able to connect to Wi-Fi by using my phone instead of manually entering my password like on my 3rd gen Nest. I made sure to take a picture before removing and installing my new thermostat. Google Home App Most of hardcore Nest lovers really like the Nest app interface. The Google Home app was not widely accepted due to its interface. Now Google has made some updates in preparation for the 4th gen thermostat. I must have opened the Nest App 40 times trying to control the new thermostat. I’m still getting adjusted with using the Google Home app. Its not bad, but its not the Nest app. Features Smart schedule is really cool. Nest learns my patterns and sets my desired temperature based on the usage patterns. The cool feature I really love is that now you are able to let the thermostat suggest schedules without having it perform the action. This is a neat feature since I have to adjust the schedules that the Nest sets sometimes in the past. Having the Nest temperature sensor included is a huge plus. I have a 2-story home, so having the ability to set the thermostat temperature based on the second level is a major plus. I don’t mind the sensor not having any motion capabilities as I have other smart devices that can detect motion. Conclusion The Google Nest thermostat is a device that gets a lot of things right. Seeing the device in person, it looks really good. I was a bit surprised of the feel though. You have to be careful installing since it feels to be mostly made of plastic. I removed the base a few times and had to be extra careful handling the device. The device is made up of mostly recycled material, so I can appreciate Google for being committed to sustainability. The new Nest thermostat is jam-packed with advanced AI features such as smart schedule, adaptive eco and proactive alerts. These features are designed to reduce energy consumption and save money. If you are current Nest user and have no issues with using the Google Home app, I definitely recommend upgrading. You won’t be disappointed.

In the world of home automation, few devices have trended as effectively as the Google Nest Learning Thermostat, especially when paired with the Nest Temperature Sensor. After using this dynamic duo in my home, I can confidently say it stands out for its thoughtful design, intuitive features, and overall performance. Installation Made Easy For those with a bit of handyman skills, installation is a breeze. The package comes equipped with all the necessary hardware and, frankly, a user-friendly guided installation that walks you through each step. For someone who knows little about HVAC systems, the initial setup might feel overwhelming at first, but the clear instructions and visually appealing interface help cushion that learning curve. Smart Learning Capability One of the most impressive features of the Nest thermostat is its ability to learn your habits. After just a few days of use, the thermostat begins to adjust the temperature according to your settings at specific times, making it a seamless part of your daily routine. This kind of adaptability is not just a convenience—it’s a true energy saver. Once it got acquainted with my schedule, I noticed a marked decrease in my energy bills, all while maintaining a cozy home environment. User-Friendly Interface The interface of the thermostat is incredibly well-designed. The sleek outer ring allows for easy rotation to adjust the temperature on the fly, which is a fantastic touch. Additionally, it displays a wealth of information—including time, weather, and more—which keeps you informed at a glance. Coupling this with the Google Home app accessibility—where you can adjust settings on the go—makes for a comprehensive control system that integrates beautifully with my existing Google Nest devices. Temperature Sensor: The Nest Temperature Sensor (2nd Gen) is a fantastic addition that really extends the capabilities of the thermostat. However, it’s essential to install the sensor at an appropriate distance from the thermostat, allowing sufficient communication without interference. This installation aspect does involve a bit of trial and error; I found that experimenting with various placements yielded the best results. Once in place, the sensor complements the thermostat's efforts exceptionally well. Performance The performance of the thermostat is nothing short of impressive. It artfully balances temperatures throughout my home, ensuring a comfortable atmosphere without overburdening the AC. There’s a noticeable ease with which it maintains climate control, efficiently managing the temperature without the air conditioning running non-stop. It’s a marvel of engineering that showcases how technology can elevate everyday living. Final Thoughts In conclusion, the Google Nest Learning Thermostat (4th Gen) alongside the Nest Temperature Sensor (2nd Gen) deserves nothing less than an 11/10. It embodies the perfect mix of art and science, with user-oriented smart technology that enhances comfort and efficiency in the home. Whether you’re a tech aficionado or a casual user, this thermostat sets a new standard in home climate control. Highly recommended!

The Google Nest Thermostat is a sleek, smart addition to any home. Its modern design blends seamlessly with most interiors, while the intuitive interface makes temperature control effortless. Installation is straightforward, and the device quickly integrates with Google Home for voice commands. The energy-saving features are impressive, including automatic scheduling and Eco Mode, which help reduce utility bills. The thermostat learns your preferences over time, adjusting temperatures accordingly. Overall, it’s a great choice for those looking to upgrade to a smart, energy-efficient thermostat.

The new Google Nest Learning Thermostat is a much needed upgrade to the most popular smart thermostat available. Now in its fourth generation, Google has updated the tried and true design with slim bezels and a polished, color matched display available in three tones of gold, silver or obsidian. I opted for gold, as it looked good from the marketing photos and would match well with a variety of finishes in our home. In the box Google provides all necessary mounting hardware, a 2nd Generation Temperature Sensor, optional cover plate, and the Nest Learning Thermostat. After unboxing, I immediately noticed how reflective the face of the thermostat was. Though the brilliant gold finish looked striking, I was curious if this affected visibility of the display. Replacing my old Nest thermostat was a breeze, but even so Google has helpful installation animations to assist you. I recommend you take a photo of your thermostat wiring before you disconnect your old one just in case you mis label a wire. In my case I did not have a common wire to provide power, but fortunately it is not required for the 4th Generation Nest Learning Thermostat. After connecting it to WiFi and a brief update, the thermostat was ready to use. As suspected, the highly reflective face made the display difficult to read under certain lighting and axis. It would have been great if they applied some sort of anti-reflective coating or offered a matte finish instead of the mirror finished display. After a few days I got accustom to it, but the thermostat is a great example of form over function. Though the face is considerably larger than the old Nest, the display does not actually go edge to edge and is only marginally larger. The new Farsight has more customization, allowing four different face options including animated weather conditions. Though I did find it cool that it can provide information beyond just the current and set temperature, I usually need to know the current or set temperature when approaching a thermostat. I have owned a few Nest thermostats over the years, and I have always appreciated their design, simplicity, and functionality. After Google acquired Nest, Nest products have not maintained their strong support of the Apple ecosystem and unfortunately I have started to avoid Google products as a result. With the latest iteration, Google has added Matter support enabling cross platform integration and finally for Apple users this brings with it HomeKit. Though limited to adjusted basic HVAC modes and setting temperature, it is generally all that is needed and is a welcome addition to HomeKit. Of course this is a learning thermostat, so naturally it learned our habits and set its own schedule after a few days. Just as previous versions, the thermostat can even use multiple temperature sensors placed throughout your home and Google even includes one now. The Google Nest Learning Thermostat is a good iteration to the original smart thermostat, providing a refreshed design and finally better integration making it easy to recommend over the previous generation. If you don’t currently have a smart thermostat and you like the striking design, the Nest Learning Thermostat is a great choice.

The 4th-generation Google Nest Learning Thermostat paired with the 2nd-generation Nest Temperature Sensor delivers a refined and intelligent climate control experience. With a sleek polished silver finish and enhanced learning capabilities, this smart thermostat stands out for both its design and performance. Performance and Efficiency This device has demonstrated exceptional performance in real-world use, particularly in managing fan functions. Its ability to intelligently circulate air based on learned patterns and sensor feedback has resulted in noticeably improved comfort and airflow. Users have reported significant energy savings, with some seeing their HVAC costs cut in half compared to previous thermostat models. The thermostat's adaptive scheduling and Eco mode optimize heating and cooling based on occupancy and outdoor conditions. It learns user preferences over time, adjusting automatically to maintain ideal temperatures while minimizing energy consumption. Design and Integration The polished silver finish and mirrored glass display offer a modern aesthetic that complements a wide range of interiors. The rotating stainless steel ring provides tactile control, while the high-resolution display offers clear visibility from across the room. Installation is straightforward, even without a C-wire, and the device supports multi-stage HVAC systems. It integrates seamlessly with Google Home, Amazon Alexa, Apple HomeKit, and other Matter-compatible platforms, making it a versatile choice for smart home environments.

The Nest Learning Thermostat 4th generation is a great smart thermostat that is packed with energy saving features! This is my first Nest thermostat as I heavily use the Apple Home app, and the previous Nest Learning Thermostat did not support integration with Apple Home. Thanks to Matter, this thermostat now natively works in the Apple Home app. While this thermostat does support the Apple Home app via Matter, there is one caveat to be aware of. My previous thermostat that had native Apple HomeKit support had the ability to set comfort settings through automations in the Apple Home app (Home, Away, Sleep, etc). Nest does not appear to support setting temperature presets/comfort settings through the Matter integration. So, while I can set an automation in Apple Home to adjust the Nest to a specific heating or cooling temperature (or auto heat/cool mode with a temperature range), there is not an option via Matter to set the thermostat to Eco mode or other temperature presets. It is disappointing that temperature presets cannot be set via Matter. With that capability, the thermostat would automatically be set at the right heating or cooling temperature based on whether the thermostat is set to heating or cooling mode. I do not want to use my thermostat in auto heat/cool mode and prefer to set the mode manually depending on the time of year. While the Matter integration does not support setting temperature presets like Eco mode, you can set up auto home and away in the Google Home app. This can put the thermostat in Eco mode when all household members have left, and it can take the thermostat out of Eco mode when the first person returns home. While I would like to be able to do this in the Apple Home app, it has worked well so far through the Google Home app. As far as looks go, this thermostat has a very sleek design which looks premium and modern. It is really nice that the thermostat turns like a dial to adjust the temperature up and down. This is very convenient. My previous thermostat had a touch screen which required multiple taps to adjust the temperature. Being able to adjust with the dial is faster and more convenient. This thermostat is very responsive when making temperature changes, which is great. It also has a lot of features and intelligence when it comes to saving as much energy as possible while still keeping you comfortable. It monitors outdoor temperatures and can make adjustments to cooling and heating to avoid wasting energy and help you save money. When you set a certain temperature, the Google Home app will also tell you how long it thinks it will take to reach the desired temperature. There is also an Activity tab in the Google Home app which is very helpful and shows you the history of temperature changes on the thermostat. Overall, this is a great smart thermostat with a wide range of features and a great design! And, I am hoping that over time, Google will add more capabilities to the Matter integration to allow for more customization outside of the Google Home app.

The installation was much easier than expected. It worked right off the bat. After I put in a simple schedule, it followed the settings. Now it adjusts to outside temperature and whether we are home. It includes another sensor for another section of the house.

Great thermostat. Very easy to install and setup. Great display and functionality. This works with Google Home app on phone. Does not integrate with Nest App

Extremely modern thermostat, hundreds of features. Most impressive was the online step by step instructions which made self-installation a breeze.

The Google Nest Learning Thermostat (4th Gen) with Nest Temperature Sensor (2nd Gen) in Polished Obsidian offers a sleek, modern design paired with powerful smart home functionality. Its intuitive learning feature adjusts to your preferred temperature settings automatically, promoting energy savings over time. The included temperature sensor enhances comfort by ensuring precise temperature control in specific rooms, making it a great option for larger homes or those looking for more consistent climate control. Integration with the Google Home ecosystem adds convenience through voice commands and app-based control, making it an excellent choice for a more automated and efficient smart home setup.

So let me start by saying I’ve been a long time nest user, this was used to replace an old unit that just got tired and worn out. We were ready to buy and saw that this new device was freshly released. It is very convenient that it comes with a remote temperature sensor for that one room that always seems to be a little hotter or colder than the main area. The display is nice to look at as well, there are a couple screen animations to choose from, one being weather that will show if it’s raining, or storming hard outside, so that’s pretty fancy. Overall it functions as you’d expect a fancy thermostat to do so. Overall a well done product.

Purchased this to replace my existing Gen 3 Thermostat. Installation was very simple and Google does a very good job helping you out, via their online setup process, to help through installation. Screen is much easier to look at, is all one piece, and includes more information, such as weather, that is not available on the previous generation. Software is very similar to last gen, however, I did experience some technical issues with my thermostat recognizing the external temperature sensor. After about 30 minutes, it seemed to have resolved itself so usure if this will re-occur or not. Overall, highly recommend for existing or new nest users, as long as you are happy with the Google/Nest ecosystem.

This was easy to install and setup. Its been working flawless since the install learning our home cooling and heating patterns.

The improvement on this from the previous generation is great. The included temperature sensor was a nice bonus as well. I like how the thermostat is now integrated into the Google Home application but I keep catching myself opening the Nest Application so that will take some getting used to. The installation was easy and straight forward. I love the increased screen sized and minimized bezels. If you’re looking to upgrade or your current thermostat is going out, I recommend grabbing this 4th gen thermostat.

Easy to install and looks great glad I made the decision to buy!!!!!!

Our house has 4 AC / furnace units and we have been running those with smart thermostats from the other big player in the market. Decided to give the Nest a shot b/c there are things we don't like about the others. Figured we'd start out with one Nest and if we were convinced we would then change out our remaining 3 thermostats. However, I think we'll be keeping our original thermostats. There are design and programming decisions on the Nest that we just don't understand. First off, the Nest is incredibly difficult to read. Not only is a very thin font used, but the display is so dim that you basically have to have your face right up to it in order to read it. This is not true of the competitor. Second, it can be difficult to tell if the unit is actually running by looking at either the thermostat or the app. The thermostat shows a faint 'glow' to let you know it's running, but for our eyes that glow can be difficult to discern. In the app, you are left to differentiate a very light, pastel gray (not running) with a very light, pastel blue (AC running). We're what you would call middle age with middle age eyes and it's difficult for us to tell. I can't imagine how hard it may be for elderly people. Next, if you go off cycle in terms of changing the temperature, there's no way to 'cancel' the change at some point and have the thermostat return to its regularly scheduled cycle. Why this feature is missing is hard for me to understand. For example, let's say the currently running schedule has the thermostat set for 73 degrees but you're feeling hot so you turn the dial down to 70, then when you start feeling cold there's no way to cancel your change. Yes, you can turn the dial back up to 73 but if you don't remember what the set temperature for the currently running schedule is, you would have to pull out your phone, open the Google Home app and look it up. And, even when you do turn the dial back up to 73, it's not like the thermostat knows that you want it to go back on schedule. It won't. It will only resume the normal schedule at the next scheduled temperature change time. Lastly, I'm not a fan of the Home app. I guess Google wants to have all their smart home devices controlled by a single app. I commend them for this, but the Google Home app is just not a nice app to use.

The device itself is beautiful. Seeing it in person is way better than pictures show. Ease of use is a plus. The only issue I have is the Google Home App. The UI and experience could be better, but for simple actions it is fine.
