Google officially ended cloud support for three early Nest Learning Thermostat models in October 2025, turning them into basic "dumb" thermostats. The first-generation (2011), second-generation (2012), and European second-gen (2014) devices each received over a decade of updates before Google cut off remote control, app access, notifications, and Google Assistant/Gemini voice commands as of Oct. 25, 2025.
The thermostats still function locally for heating and cooling, but lose all smart features that relied on Google Home and Nest cloud services. Google stated the move allows focus on "cutting-edge features" for newer models.
A free, open-source software project now restores cloud functionality for affected devices, offering a workaround for owners who want to keep smart capabilities without buying new hardware.
