Smart Thermostat Connectivity Ends for Some Users This Week

Households across the UK using specific models of the Google Nest Learning Thermostat are facing a significant disruption. Starting on October 25, 2025, three models will lose connectivity to both the Google Nest app and the Google Home app, rendering them unable to function within users’ smart home systems.

The affected models include the first-generation Nest Learning Thermostat released in 2011, the second-generation version from 2012, and the second-generation European model from 2014. Homeowners are advised to check their device model to avoid unexpected disconnections. After the cutoff date, these thermostats will not receive any further software updates or be controllable remotely.

Google’s decision to discontinue support for these older models aims to streamline its focus on newer technology. A company spokesperson stated, “To fully invest in these advancements and bring you the most cutting-edge features on our latest generation of Nest thermostats, we will be transitioning away from supporting some of our earliest devices.”

For users relying on these models, the implications are significant. The Nest support page clarified that starting October 25, the thermostats will be unpaired from their apps, and features such as Home/Away Assist will become inactive. Additionally, Nest Protect devices, which include smoke and carbon monoxide alarms, will also disconnect from the thermostat, eliminating emergency shut-off functions.

Despite the impending disconnection, the thermostats can still be used manually. Users will retain the ability to adjust temperatures and modify existing schedules directly from the devices themselves. Nevertheless, the lack of remote control capabilities is a considerable setback.

In response to this transition, Google is offering a discount to affected users. While the company no longer sells Nest thermostats in the UK, it is providing a 50 percent discount on the Wired Smart Thermostat X – Starter Kit, reducing the price from £159.99 to £109.99. Customers will receive an email with a personalized link to access this offer.

The decision to halt support for older models has raised concerns among users. Many have expressed frustration at being left without options, especially since the newer products are not available for purchase in the UK. A Google representative explained that the diverse heating systems in Europe pose unique challenges, leading to the decision to partner with established smart thermostat companies instead.

“We remain deeply committed to our users in Europe and will continue to launch new devices and features in Europe as well as globally,” the spokesperson added.

For those using the outdated models, it is crucial to act quickly to ensure they are prepared for the upcoming changes. Households are encouraged to monitor their emails for further updates from Google regarding the transition and available options.
