Exciting Updates on the Fourth-Generation Nest Learning Thermostat

Recently, leaked images posted on X by @MysteryLupin have revealed some exciting updates on the fourth-generation Nest Learning Thermostat. The images showcase not only the new thermostat but also new temperature sensors and several other thermostats in the Nest lineup. Interestingly, the Nest Thermostat (2020) was missing from the pictures, suggesting that it may not be compatible with Nest’s room sensors.

The new fourth-generation thermostat appears to bear a striking resemblance to the third-generation model, with a more curved display and the retention of the physical dial. According to observations made by 9to5Google, the display is likely to be touchscreen, similar to the previous model, and features a new icon with three wavy lines. This new icon seems to indicate that the thermostat will also function as an indoor air quality monitor, a novel feature for Nest thermostats.

Additional Features and Functionality

In addition to the leaked images, a screenshot of the Google Home app with a new Climate screen further supports the theory that the new thermostat will include an air quality index score. This suggests that users will have access to more comprehensive environmental data, enhancing their overall home automation experience.

Furthermore, it is worth noting that the new thermostat seems to be compatible with a redesigned Nest Temperature Sensor (second-gen). These sensors, which can be wall-mounted or placed on a table, will come at a cost of $39 each, or three for $99, and boast a three-year battery life. While the current sensors help balance heating and cooling by transmitting temperature data from various rooms to the thermostat, they do not detect presence. However, there is hope that the new sensors will offer improved functionality in this regard.

9to5Google has uncovered FCC filings indicating that the new thermostat may feature Google’s Soli radar technology. This innovative radar system can illuminate the thermostat’s display when a user approaches and detect presence for integration into Google’s Home & Away Routines. Notably, the current Nest Thermostat (2020) already includes Soli, while the third-gen Nest Learning Thermostat relies on motion sensors for similar functionalities.

Interestingly, the FCC filings did not mention a Thread radio in the new thermostat, despite Thread’s initial development for the original Nest thermostat. It is surprising that even the 2020 model lacks Thread compatibility, as this technology was intended to enhance connectivity and communication between smart home devices.

Over the years, Google has not introduced many updates to the Nest Learning Thermostat, which focuses on adapting to users’ heating and cooling patterns rather than adhering strictly to a schedule. In contrast, the newer, more affordable Nest Thermostat emphasizes support for Matter, an emerging smart home standard championed by Google. The current Nest Learning Thermostat is available at a reduced price of $169, down from $249.

With a significant Google hardware event on the horizon for August 13th, it remains to be seen whether these leaks regarding the fourth-generation Nest thermostat are accurate. Exciting updates and new features could potentially revolutionize the smart home market and redefine the standard for thermostat functionality.
