The next generation Nest thermostat is here, along with a new temperature sensor and of course the power of AI. Get all the pricing, specs and availability.
Google has unveiled the latest iteration of its iconic smart thermostat, the Nest Learning Thermostat (4th generation), promising an even smarter, sleeker, and more energy-efficient experience for homeowners. It should come as no surprise that the new Nest Learning Thermostat comes equipped with advanced AI-driven features thanks to Gemini, along with a larger and more dynamic display, and a redesigned Nest Temperature Sensor, all aimed at enhancing both comfort and sustainability.
The Nest Learning Thermostat, first introduced 13 years ago, was indeed a game-changer in the smart home industry, leading the transformation of thermostats from basic household gadgets into intelligent, aesthetically pleasing devices. The newly reimagined 4th generation model takes this concept further, featuring a sleek, slim profile and a 60% larger domed crystal LCD display that eliminates bezels for a seamless look. The device is available in three elegant finishes—Polished Silver, Polished Obsidian, and Polished Gold—ensuring it complements any home decor.
At the heart of the new Nest Learning Thermostat, like pretty much everything coming out of Google these days, is another chapter of Gemini usage driving an AI system that automatically adjusts the temperature based on user patterns, helping to optimize comfort while reducing energy consumption. The AI-driven Smart Schedule feature quickly learns the homeowner's preferences and adjusts settings accordingly, even taking into account outdoor weather conditions to maintain an ideal indoor climate. The thermostat also introduces Smart Ventilation, a new feature that optimizes fresh air intake based on outdoor air quality and temperature, while also monitoring humidity levels to prevent mold and condensation.
One of the aspects of home heating that I've personally discovered is the need for in-room temperature sensors, so I was delighted to see that included with the thermostat is the redesigned Nest Temperature Sensor. This little device allows for precise control of hot and cold spots within the home. Homeowners can now manage up to six temperature sensors, averaging temperatures across them or selecting which ones to prioritize at different times of the day. The sensor’s discreet, pebble-like design ensures it blends seamlessly into any room.
The Nest Learning Thermostat also supports Google's Nest Renew program, enabling users to shift energy consumption to cleaner, less expensive times, contributing to a more sustainable energy grid. The thermostat's System Health Monitor feature further ensures that HVAC systems run efficiently by tracking performance and alerting homeowners to potential issues before they become costly problems.
The thermostat is designed for easy installation and setup, compatible with most HVAC systems thanks to a new 12-terminal backplate. It integrates smoothly with the Google Home app, allowing users to control all their smart home devices from one place. The device is also Matter-certified, making it compatible with other Matter-supported smart home apps.
The new Nest Learning Thermostat is now available for pre-order at the Google Store and select retailers, priced at $279.99 in the U.S. and $379.99 in Canada, with official availability starting August 20. Each thermostat includes a Nest Temperature Sensor, with additional sensors available for purchase separately. See the full specs of both devices below
