If you’re the owner of a Nest Learning Thermostat that’s more than 10 years old, you’d better start thinking about an upgrade.
Google just announced that it will soon drop support for the first- and second-generation Nest Learning Thermostats. The devices won’t stop working completely, but remote access is going away, as are software updates and compatibility with the Google Home app.
The older Nest Learning Thermostats that are losing support include the second-generation units for the U.S., released in 2014, as well as the European version of the second-gen thermostat, which also went on sale in 2014. The original Nest Learning Thermostat, which was released only in the U.S., landed in 2011.
Google says it will drop support for the thermostats starting October 25, 2025. Besides no longer receiving software updates, the older Nest Leaning thermostats will lose Nest and Google Home app support, meaning no more out-of-home control. Google Assistant will also lose access to the units.
You will still be able to control temperature, mode, schedules, and other settings manually on the thermostat itself, and existing schedules will continue to operate, Google added.
At least Google is offering discounts to affected Nest users for their trouble. U.S. owners of the older Nest Learning Thermostats can get $130 off the fourth-gen Nest Learning Thermostat, while Nest customers in Canada can expect a $160 discount for that same unit.
Meanwhile, European users with the soon-to-be-unsupported Nest Learning Thermostats will get half-off the Tado Smart Thermostat X – Starter Kit.
Google said it will reach out to affected Nest users via email with the discount offers.
Besides chopping support for the European version of the Nest Learning Thermostat, Google says it will exit the thermostat market in Europe altogether, as European heating systems “have a variety of hardware and software requirements that make it challenging to build for the diverse set of homes.”
The third-gen Nest Learning Thermostat and the Nest Thermostat E will continue to be sold in Europe “while current supplies last,” and both those models will continue to be supported, Google said.
The news that Google is dropping support for its oldest Nest thermostats comes barely a month after it discontinued the Nest Protect smoke detector and the Nest X Yale Lock, thus withdrawing as a manufacturer in those key smart home categories.
