If you’re one of the early adopters who proudly installed a Nest Learning Thermostat back in the 2010s, big changes are coming. Google has announced that, from October 25, 2025, it will end cloud and app support for the first and second-generation Nest Learning Thermostats.

In practice, that means your device will still control your heating, but it will lose all its smart features. You won’t be able to adjust settings from your phone, use voice commands, or receive alerts. Essentially, your “smart” thermostat will become a manual one overnight.

Affected models include:

Nest Learning Thermostat (1st Gen, 2011)

Nest Learning Thermostat (2nd Gen, 2012)

Nest Learning Thermostat (2nd Gen EU Version, 2014)

In a broader shift, Google has also confirmed it won’t be developing new Nest thermostats for the European market. The company cited the complexity of regional heating systems, from varied boiler types to evolving heat-pump technologies, as a key reason. Instead, Google will focus on its Google Home ecosystem, supporting third-party brands like Heatmiser, which already cater to local standards.

Current models, such as the Nest Learning Thermostat (3rd Gen) and Nest Thermostat E, will remain available while stocks last and will continue to receive security updates.

Google is also ending production of the Nest Protect smoke and carbon-monoxide alarm, a device that revolutionised home safety with spoken alerts, dual sensors, and thoughtful design features like Pathlight. Existing units will continue to work and receive updates until their expiry dates, but no new versions are planned for Europe. Google says lessons from Nest Protect will feed into its partnership with First Alert, though for now, that collaboration is limited to the US market.

For both homeowners and installers, this is a reminder that when smart devices depend on cloud services, they only stay “smart” as long as the manufacturer keeps supporting them. Losing app control for a thermostat is inconvenient; losing it for an EV charger or solar inverter could be far more serious.

As the UK moves toward new standards for connected appliances, from heat pumps to EV chargers, consumers and installers alike will need to think carefully about reliability, interoperability, and long-term support before committing to smart tech.

If you are a current Nest user and are looking to upgrade to a more stable platform, we recommend the Heatmiser NeoHub Mini Kit, which is a direct replacement and is available in white, black or silver options
