The Google Nest Learning Thermostat (4th Gen) paired with the Nest Temperature Sensor (2nd Gen) has been an excellent upgrade for our home. Installation was straightforward, and the setup through the Google Home app was smooth and intuitive. The thermostat looks sleek and modern, and the display is clear and easy to read. The learning feature works well—after a short adjustment period, it began automatically optimizing our heating and cooling schedule without constant manual input. The temperature sensor is a great addition. It allows us to prioritize comfort in the rooms we actually use, rather than relying solely on the thermostat’s location. This has made a noticeable difference in maintaining consistent temperatures, especially during the night. Energy efficiency is another strong point. We’ve already seen more balanced heating cycles and less unnecessary runtime, which should translate into savings over time. Overall, this is a smart, well-designed product that delivers on both comfort and convenience. Highly recommended for anyone looking to modernize their home climate control system.

Yikes what a neat device! It does learn from your daily movements to adjust either heating or cooling regime when you leave the house. It compensates for outside temps and figures out the time required to meet your set temps when you return to the home. There are many settings for fan timings ( to circulate stall air). To use the devices many features one should use the Google home app which requires WiFi. Should this be a ‘no -no’ it can be easily programmed directed by using the thermostat. Our one negative comment is the price. A Generation 3 unit costs less but lacks conservation features of this unit. Time will tell if the units features will save us energy costs. Google emphasized it will save.

I love this thing! For something as simple as a thermostat, the additional functionality this provides is a game changer

Upgrading to this thermostat has completely changed how I think about home temperature control. It's not just a programmable thermostat – it's actually smart in ways that make a real difference in comfort and energy savings. The learning capability is impressive. After the first week or so, it started anticipating when I wanted the temperature adjusted without me having to do anything. It picks up on your patterns and creates a schedule automatically based on how you actually use your home. That means you don't have to spend time programming complicated schedules or remembering to adjust things manually. It just figures out what you want and does it. The display is gorgeous. It's got this clean, modern look that actually adds to your home's aesthetic rather than being an eyesore like traditional thermostats. The screen is bright and easy to read from across the room, and the interface is incredibly intuitive. When you walk up to it, it lights up and shows you the current temperature. The whole interaction feels polished and well thought out. What sets this apart from other smart thermostats is how well it works with the temperature sensor that's included. You can put the sensor in the room where you spend the most time, and the thermostat will prioritize that room's temperature when making decisions. This is huge if your home has uneven heating or cooling. Instead of managing the temperature based on where the thermostat is mounted, it can focus on keeping comfortable the spaces where you actually are. The energy savings are noticeable. The system is smart about when to heat or cool, and it's not wasting energy when you're not home. It can detect when you've left and automatically adjust to save energy, then bring things back to your preferred temperature before you return. Over time, those savings add up, and you can actually see the impact in your energy bills. Remote control through the app is seamless. Whether you're at work, traveling, or just in another room, you can check and adjust your home's temperature from your phone. The app is well-designed and responsive. It gives you detailed information about your energy usage and even provides reports on how efficiently your system is running. That level of insight is something you just don't get with a traditional thermostat. Installation was straightforward. The instructions are clear, and if you're comfortable with basic DIY projects, you can handle it. There's also a compatibility checker on their website to make sure it'll work with your HVAC system before you buy. Once it's installed and connected to WiFi, the setup wizard walks you through everything step by step. Voice control works perfectly with both Alexa and Google Assistant. Being able to adjust the temperature with voice commands is one of those conveniences that seems small but becomes something you use all the time. "Hey Google, set the temperature to 72" is so much easier than walking over to adjust it manually. The Nest Aware features give you additional insights into your home's environment. You get alerts if there are unusual temperature changes, which can help you catch problems with your HVAC system early. The system also provides tips on how to optimize your settings for better efficiency. Build quality is excellent. This feels like a premium product from the moment you take it out of the box. The materials are high quality, the engineering is solid, and everything about it feels durable and well-made. It's clear this was designed to last and to look good doing it. The fourth generation improvements are noticeable if you've used previous versions. The display is better, the sensor integration is more sophisticated, and the overall performance is smoother. Even if you haven't used an older model, you're getting the benefit of years of refinement and improvements. For anyone serious about smart home technology or just wanting better control over their heating and cooling, this is an investment that pays off. The combination of learning capabilities, energy savings, remote access, and the included temperature sensor makes this a complete solution. It's made managing home temperature effortless while actually reducing energy costs. Really impressed with how well this performs.

Very easy transition from old the thermostat to the new, several new options with the remote sensor being available. I am please with the item and its functionality, installation was relatively straight forward. You do need Google home as the Nest software will not operate it although Nest still recognizes the smoke/CO2 detectors.
