The Dumb Home Google announces 1st and 2nd gen Nest Thermostats will lose support in October 2025 Affected units will work locally, but smart features will shut down in October.

The company has announced that the first and second generation Nest Learning Thermostats will lose support in October 2025, disabling most of the connected features. Google is offering some compensation for anyone still using these devices, but there's no Google upgrade for European users. Google is also discontinuing its only European model, and it's not planning to release another. Both affected North American thermostats predate Google's ownership of the company, which it acquired in 2014. Nest released the original Learning Thermostat to almost universal praise in 2011, with the sequel arriving a year later. Google's second-gen Euro unit launched in 2014. Since launch, all these devices have been getting regular software updates and have migrated across multiple app redesigns. However, all good things must come to an end. As Google points out, these products have had a long life, and they're not being rendered totally inoperable. Come October 25, 2025, these devices will no longer receive software updates or connect to Google's cloud services. That means you won't be able to control them from the Google Home app or via Assistant (or more likely Gemini by that point). The devices will still work as a regular dumb thermostat to control temperature, and scheduling will remain accessible from the thermostat's screen. If you have one of these units, Google will be reaching out via email with some deals to soften the blow. In the US, owners can get a $130 discount if they upgrade to the fourth-gen Nest, which was released just last year for $280. In Canada, the discount will be CA$160.

Heating and cooling systems in Europe have various quirks that set them apart from North American systems, and consequently, it has been more than a decade since Nest released a smart thermostat adapted to the continent. And it never will again, the company confirms. The European seconnd-gen Nest Learning Thermostat will be the last from Google. For anyone in Europe deeply embedded in the Google ecosystem. Google recommends picking up a third-party unit that works with Google Home. In compensation for the inconvenience, owners of the old second-gen device can get a 50 percent discount on the Tado Smart Thermostat X, which works with Euro systems and Google Home. This move comes just weeks after Google confirmed it had discontinued the Nest Protect smoke and carbon monoxide alarm, as well as the Nest x Yale Lock. Google Nest isn't making a replacement, so Nest fans were directed to third-party First Alert and Yale devices that will work with Google Home. Google has been shedding jobs in the Platform and Devices division that includes Nest. With fewer workers, it's not surprising the team would look to drop support for its older products. And in fairness, these devices have lasted far beyond Google's measly five-year commitment. So you can't say they didn't warn you.
