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
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

- 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.
