Google ended support in October 2025 for three older Nest Learning Thermostats: the first-generation model from 2011, the second-generation model from 2012, and its European version from 2014. Although the devices still control heating and cooling locally, losing access to Google’s cloud services removed the features that made them smart: app-based monitoring and remote adjustments, phone notifications, voice control, and integrations with Nest Protect and third-party assistants. Home/Away Assist, shared Eco Mode, and emergency shutoff also stopped working. Owners can still change temperatures, choose operating modes, and set schedules directly on the thermostat, but cannot manage it through Google Home or the Nest app. Google gave advance notice and offered upgrade discounts; the shutdown followed more than a decade of support.
An open-source project called No Longer Evil, created by Cody Kociemba, offers a way to restore remote control and other internet-connected features. Owners can install new firmware and use the project’s hosted servers with a free account, or run the service themselves through a Home Assistant add-on or a custom server. The project restores functions such as remote adjustments, scheduling, and automatic Away detection, giving the discontinued devices a possible second life. Newer Nest models, including the third- and fourth-generation Learning Thermostats and the Thermostat E, were not affected by this cutoff. The shutdown nevertheless shows that cloud-dependent features can disappear even when the hardware remains functional.
