The Nest Learning Thermostat (4th gen) is Google’s smartest, most advanced thermostat yet. 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 make sure your heating and cooling systems run smoothly.²
Improved compatibility.
It works with most 24V systems, including gas, electric, oil, forced air, heat pump, and radiant, and no C wire is required for installation in most homes.³
Better visibility into adjustments.
Smart Schedule learns the temps you like, and when you like them. It asks for permission to make schedule changes to help you save energy. You'll receive notifications in the Google Home app, and you can view and accept changes with a tap.¹
Beautiful design.
With a 60% larger display⁴ and Dynamic Farsight, you can see info from across the room.¹ Choose the design – a clock, the temp, weather, and more. It automatically adjusts brightness for the best readability or you can adjust manually.
Easy control in the Google Home app.
Adjust the temperature on your phone from anywhere¹ or by using your voice.⁵ It’s easy to install yourself³ and it’s Matter compatible for simple integration into your smart home.⁶
Manage hot and cold spots.
The Nest Learning Thermostat (4th gen) comes with a Nest Temperature Sensor (2nd gen) and works with any Nest Temperature Sensor. Put a sensor in any room and use the Google Home app to set the temp it should reach at a certain time of day.
Savings you can count on.
The Nest Learning Thermostat (4th gen) can help save an average of 12% on heating bills and 15% on cooling bills.⁷
New natural heating and cooling.
Your thermostat learns how the temperature outside affects the temperature inside (for example, when the sun coming through the windows will heat the house naturally) and pauses your system to help you save.¹
New Adaptive Eco.
It uses the temperature outside to help find an energy-saving temperature when you’re away and returns to a comfortable temperature within an hour of your return.¹
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.⁸
Your HVAC heads-up.
When it’s time to change your air filter, you’ll get an alert based on actual use.⁸ And you’ll get seasonal maintenance reminders.
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.¹,⁹
Clean energy made simple.
Energy Shift from Nest Renew can automatically shift your energy use to cleaner or cheaper times.¹⁰

- A: AnswerHi there, thank you for your inquiry. The new Google Nest Learning Thermostat (4th Gen) does not require a sensor to function properly. However, for optimal temperature control and comfort, we strongly recommend using a sensor. You may also place the Google Nest Temperature Sensor in a different room to monitor and control the temperature in that specific area.

- A: AnswerHi Sparkz. Thanks for your inquiry. The Nest Learning Thermostat 4th Gen requires a specific mounting bracket and wire harness that's different from previous models. Please use the ones included with your new thermostat.
Answered by Google Team
- A: AnswerHey there. The Nest Learning Thermostat 4th generation typically activates the AC or heat when the ambient temperature deviates from the set point by a small margin. This margin is often around 0.5 degrees Fahrenheit. It's important to note that this can vary slightly depending on factors like the specific settings on your thermostat, the efficiency of your HVAC system, and environmental conditions.

Beautiful Thermostat
The new generation Nest thermostat has blown me away with how gorgeous it looks on the wall. I get constant compliments on how beautiful the thermostat looks. Typical smart thermostat features, and I love the included sensor you can place in an area that may run hotter or colder so your thermostat can use that location to heat or cool.

Simple, easy, and worth every penny!
This is one of the best smart thermostats I’ve ever bought and used. I installed it myself, and it was very easy and straight forward to follow the directions to install. As an added bonus, this is compatible with my security system, so I can create custom scenes utilizing these two things together (such as automatic temperature changes when leaving/arriving). Im also a fan of being able to track our HVAC usage. A new feature with this is the secondary sensor which has been nice to have, and has all sorts of convenient benefits. Overall VERY happy with this. Ive had my thermostat about a month now with no issues.
