A new Nest Learning Thermostat might be on the way

Leaked images posted on X by @MysteryLupin show a 4th-generation Nest Learning Thermostat and new temperature sensors, as well as several other thermostats: Nest E, Nest Learning Thermostat (3rd Gen). Missing from the pictures is the Nest Thermostat (2020), presumably because it’s not compatible with Nest’s existing room sensors.

The new addition looks similar to the third-generation model but appears to have a more curved display while retaining the physical dial, as pointed out by 9to5Google. The display is likely a touchscreen, as with the third-generation model, and the image shows a new icon with three wavy lines.

This indicates that the new thermostat is also an indoor air quality monitor, which would be a new feature for Nest thermostats. A leaked screenshot of the Google Home app with a new Climate screen backs up this theory by showing an air quality index score.

Since the Nest E, which has been discontinued in the US, is pictured, this could indicate that unlike the Nest Thermostat (2020), the new model will also launch in Europe.

The thermostat appears to work with a redesigned Nest Temperature Sensor (2nd gen), which, like the current models, is wall-mountable or can be placed on a table. However, it doesn’t have the Nest branding at this time and is rounder and squishier-looking. The posts indicate that these will cost $39 each, or three for $99, and have a three-year battery life.

That’s the same price as the current sensors, which feed the temperature from other rooms of your house to the thermostat to help balance heating and cooling. But as we said in our review, they are limited compared to those from competitors like Ecobee, as they don’t detect presence. Hopefully these new versions will bring more function.

9to5Google has dug up FCC filings showing the new thermostat may sport Google’s Soli radar, used to light up the thermostat’s display when you approach it, and detect presence to feed into Google’s Home & Away Routines. Soli is in the Nest Thermostat (2020) but not in the Nest Learning Thermostat 3rd gen from 2015, which uses motion sensors.

It’s been a long time since Google launched a new Learning Thermostat, which can adapt to your heating and cooling patterns instead of mainly sticking to a schedule, as the newer, cheaper Nest Thermostat does.
