Google announced this week that beginning on October 25, it will no longer support or release software updates for the first and second generation Nest Learning Thermostats. And it will completely stop launching new Nest products in Europe.

That means owners of the Nest thermostats released in 2011 and 2012 (as well as the version released in Europe in 2014) won’t receive updates, and their devices will no longer be supported in the Nest and Home apps. They will, however, be able to adjust temperature and schedules directly on their devices.

“To fully invest in [future] advancements and bring you the most cutting-edge features on our latest generation of Nest thermostats, we will be transitioning away from supporting three of our oldest devices, each over a decade old,” Google said.

As for why it will no longer launch Nest thermostats in Europe, the company added, “Heating systems in Europe are unique and have a variety of hardware and software requirements that make it challenging to build for the diverse set of homes.” Existing Nest devices will still be sold in Europe while supplies last.
