Old Nest thermostats are about to become dumb: What you need to know

Google is terminating all smart features of older Nest thermostats.
This change happens in October and will affect the Gen 1, Gen 2, and Gen 2 (European version) models. Other models are unaffected.
As a consolation, Google will send affected users hefty discount coupons that they can use towards a new thermostat.

If you invested in the Google Nest ecosystem way back in the day by buying an early version of a Nest thermostat, we have bad news for you. On October 25, 2025, Google will terminate all support for early generations of the Nest Learning Thermostat. This not only means that the devices will stop getting software support — they will cease to be accessible in the Nest and Google Home apps, no longer be able to be controlled while you’re away from home, no longer support Google Assistant, and no longer support presence sensing.

In brief, your “smart” thermostats are about to become “dumb” thermostats. They will still fundamentally work — you’ll still be able to manually change the temperature and change schedules on the device itself — but it will no longer do most of the things you have relied on it to do for the past decade, and no longer integrate into your wider smart home.
