Your old Nest Thermostat is going to lose app control later this year

Google dropped some sad news for owners of its earliest smart thermostats this week. Citing the increasing difficulty of updating hardware that’s well over a decade old, the company announced it will officially end support for its Nest Learning Thermostat (1st gen, released 2011), Nest Learning Thermostat (2nd gen, 2012), and the Nest Learning Thermostat (2nd gen, Europe version, 2014). The cutoff date is set for October 25, 2025.

So, unfortunately, if you own one of these specific models, your thermostat will no longer connect to the Nest or Google Home apps after October 25, 2025. This means no more remote control via your phone, no Google Assistant voice commands, and connected features like Home/Away Assist will stop working. Google also notes Nest Protects will disconnect, and emergency shut-offs won’t run.

The thermostat itself won’t be bricked – you’ll still be able to walk up to the unit and manually adjust the temperature, change modes, and even modify existing schedules directly on the device. However, without software or security updates, Google warns that performance might become unpredictable over time.

To soften the blow of losing smart functionality, Google stated it will be emailing eligible owners of these affected Gen 1 and Gen 2 thermostats with special discount offers to upgrade to newer hardware. These include:

• US: $130 off the Nest Learning Thermostat (4th gen) (MSRP $279.99)
• Canada: $160 off the Nest Learning Thermostat (4th gen) (MSRP $379.99)
• Europe: 50% off the Tado Smart Thermostat X – Starter Kit (which works with Google Home)

Google also mentioned they will no longer launch new Nest thermostat models in Europe due to the complexity of diverse heating systems there, instead focusing on its Google Home platform and partners. Existing supported models (like the 3rd Gen) will continue to sell while supplies last.

While over ten years of support is a decent run for consumer tech, losing core smart features is definitely a downside for these early Nest adopters. But keep an eye on your email for that discount offer if you’re affected, and if you’re looking for further details, you can read Google’s full announcement here.
