About This Product

Meet the next-gen Nest Learning Thermostat. It's a brilliant way to save energy and keep your home comfortable. It learns the temperatures you like, when you like them, even as your routine changes.1 It gets to know how outdoor temps naturally heat and cool your home to save energy.1 And it helps catch heating and cooling system issues early.2

Highlights

  • The right temp, right where you want it. The Nest Learning Thermostat works with any Nest Temperature Sensor. Put the included 2nd gen sensor in any room to help manage hot and cold spots.
  • Saves energy while you're away. Adaptive Eco helps find an energy-saving temperature, based on the temperature outside.1 So you save when you're away, and come back to a comfy home.
  • Teams up with Mother Nature. Your thermostat learns how the temperature outside affects the temperature inside, and pauses your system to help you save.1
  • The schedule that programs itself. Smart Schedule learns the temps you like, and when you like them. It suggests tweaks to help you save, and you can accept them in the Google Home app.1
  • One great app for your whole home. Control your Nest Learning Thermostat (4th gen) and your other compatible smart home devices in the Google Home app. Remote control and mobile notifications require working internet and Wi-Fi.
  • Looks out for your heating and cooling system. System Health Monitor helps catch many issues early. And if something needs attention, it can send an alert. 2
  • Your HVAC heads-up. When it's time to change your air filter, you'll get an alert based on actual use. 2 And you'll get seasonal maintenance reminders.
  • It’s easy to install yourself, it usually takes 40 minutes or less, just follow the step-by-step instructions in the Google Home app, 3 no need to worry about wiring either, with Power Sharing, there's no C-wire required for installation in most homes, 3
  • Smart is in the air, to save energy, smart ventilation brings in fresh air when outdoor air quality is healthy and most efficient, like when temps are mildest, 1 requires compatible HVAC ventilation system
  • Clean energy made simple, Energy Shift from Nest Renew can automatically shift your energy use to cleaner or cheaper times, 1 Energy Shift makes small adjustments to your Nest Learning Thermostat set points which can shift electricity usage from your heating and cooling system, learn more at support.google.com/googlenest/answer/10975756?hl=en, only available in areas served by major continental US grids (see g.co/nest/repwr), prioritize less expensive energy only available for customers on certain electric utility time-of-use rates (check availability at g.co/nest/retou)

                I have a house with 2 Air Conditioners with 2 controllers (upstairs and downstairs). Can I use two thermostats in the same house? Second question - are the temperature sensors thermostat specific?
                ByJul 1, 2026
                1 Answer | 
                Answer This Question

                Thanks for reaching out. Yes, you can definitely use multiple Nest Thermostat Gen 4 devices in the same home to manage different zones, such as your upstairs and downstairs units. Regarding your second question, each Nest Temperature Sensor is paired to a specific thermostat within your Google Home app. You can assign sensors to the thermostat that controls the heating or cooling for that specific area.

                  This is my second time purchasing this specific model. The first time I had to exchange because it was short circuiting the unit. It would turn the unit off for 2 seconds and immediately turn on. But to be fair, the capacitor had gone out prior to that, so not sure if that had anything to do with it or, I got a faulty thermostat. However, I liked the capabilities the thermostat has, which is why I exchanged it for a new one. So far, no issues and works as it initially did. Love the monthly pictures!

                  So far I am pleased with the Google nest learning thermostat. It is highly functional and very good looking. Cools my home efficiently and works well with my HVAC unit. I only had it installed a few days, so far I love it. I had it professionally installed because I had other work done.

                    AWFUL
                    Worst purchase I've ever made.... Two zone home. One zone has this product. It decides to turn itself off anytime I'm not home letting this zone get over 85 degrees. When I get home it decides it'll only run the AC for 5 mins at a time and then take a brake. This section of the house is constantly over 87 in a house that has a working AC unit... I guess what this thing learns is that my families comfort is not its concern. The features are dumb and the fact that the little SOB is pure evil eliminates any reason to purchase it.

                      This is our third and fourth purchase of the nest. We first had one in another home that we sold. We purchased a condo and put one in there. Then we decided to upgrade our 3 story home and put 2 more on different floors in our current home. The nest is a simple and affordable means to upgrade your thermostat(s). We always have info at our fingertips, even when we are not at either home. Also, the look is glamorous on the wall.

                      Smart features work well but app setup was frustrating
                      Installed this about three weeks ago replacing my old basic programmable thermostat, and after getting through the initial setup headaches it’s been working nicely. The installation took me about 45 minutes following the step-by-step instructions in the app - my house didn’t have a C-wire but the power sharing feature worked fine without needing to run new wiring which was a relief. The thermostat itself looks sleek on the wall, definitely more modern than the beige box I had before. The display is crisp and you can customize what it shows from across the room which is a nice touch. Now the app setup was where I ran into frustration - connecting it to wifi took several attempts, and migrating from my old Nest account to the Google Home app was confusing with multiple prompts and permissions. Once that was sorted though, controlling it remotely works smoothly. The included temperature sensor for another room is useful - I put it in our bedroom which tends to run warmer and now the system balances things better. The learning feature does seem to pick up on our schedule after a couple weeks, though I still manually adjust it sometimes. The energy savings claims are hard to verify this early but I’ve noticed the system runs less often with the adaptive eco mode when we’re away. The alerts for filter changes and system monitoring are helpful reminders. Voice control through our smart speaker works reliably. One minor gripe is the touchscreen can be a bit sensitive, sometimes registering accidental touches when I just want to glance at it. The Matter compatibility is good for future-proofing with other smart home stuff. For anyone already in the smart home ecosystem this integrates well, just budget extra time for the initial app configuration.​​​​​​​​​​​​​​​​
