Google’s October 25, 2025 support cutoff affects only three early Nest Learning Thermostat versions: the 2011 first generation, 2012 second generation, and 2014 European second generation. They were removed from the Nest and Google Home apps and lost remote, Google Assistant, software, and security support, but their wall controls still work. Identify your model first, then keep it as a local-only thermostat, replace it if you need connected features, or recycle it responsibly.
Which Nest thermostats actually stopped receiving support?
This was a targeted thermostat sunset, not a shutdown of every old Nest product. Google’s announcement covers the following variants:
| Thermostat | Support status after October 25, 2025 | What still works |
|---|---|---|
| First-generation Nest Learning Thermostat (2011) | Unpaired and removed from the Nest and Google Home apps; no phone control, Google Assistant control, software updates, or security updates. | Temperature changes and schedule edits made on the thermostat itself. |
| Second-generation Nest Learning Thermostat (2012) | Same end of cloud and update support. | Local temperature and schedule controls. |
| European second-generation model (2014) | Same end of cloud and update support. | Local temperature and schedule controls. |
| Nest thermostats launched in 2015 or later | Google says these remain supported in the redesigned Google Home app. | App features depend on the specific model and current Google Home support. |
Google Nest summarized the change this way: “You will no longer be able to control them remotely from your phone or with Google Assistant, but can still adjust the temperature and modify schedules directly on the thermostat.”

Identify the model before removing it
Do not pull an old-looking thermostat off the wall based on appearance alone. Confirm its generation using the model information in the app or on the device and compare it with the launch years above. Before disconnecting anything:
#1 Best Overall
- Nest’s smartest, most advanced thermostat yet, the Google Nest Learning Thermostat (4th gen) is a beautiful, brilliant way to save energy, keep your home comfortable, and help make sure your heating and cooling systems are running smoothly[4]
- Savings you can count on: The Nest Learning Thermostat can help save up to 31% on heating and cooling bills [2]
- Improved compatibility: It works with most 24V systems, including gas, electric, oil, forced air, heat pump, and radiant, and no C wire is required for installation in most homes; visit the Nest Compatibility Checker for more info[5]
- Easy control in the Google Home app: Adjust on your phone from anywhere[1] or by using your voice with Alexa, Siri, or Google Assistant smart speaker[3], it’s easy to install yourself and it’s Matter compatible for simple integration into your smart home[5]
- Beautiful design: With a 60% larger display[11] and Dynamic Farsight, you can see info from across the room[1]; choose the design, like a clock or the weather; it automatically adjusts brightness for the best readability or you can adjust manually
- Photograph the wiring. Capture every terminal label and wire position, including any HVAC labels inside the wall plate.
- Record the schedule. Write down temperatures, time periods, and weekday or weekend differences that you may want to reproduce on a replacement.
- Save routines and integrations. Note household automations and third-party connections. Google’s earlier Works with Nest transition showed that integrations may need to be recreated or migrated to Google Home.
- Check your replacement requirements. Confirm the HVAC system type, wiring, regional model, power needs, and whether a professional installation is required before ordering anything.
Option 1: Keep the affected thermostat as a local controller
Keeping the unit is reasonable if you are comfortable changing settings at the wall and do not depend on remote monitoring. It can continue acting as a manually controlled programmable thermostat, provided the HVAC installation itself remains compatible and functional.
- You can change the target temperature at the thermostat.
- You can edit schedules directly on the thermostat.
- You cannot control it from a phone or Google Assistant.
- It receives no further software or security updates.
- You lose cloud-dependent convenience such as checking or changing the temperature while away.
That last limitation matters for homes where remote checks are part of vacation planning, freeze protection, or care for children, pets, or vulnerable occupants. If those functions are important, treat local-only use as a temporary compromise rather than a connected replacement.

Google’s trade-in route
Google’s cited trade-in offer advertised $50 off a Nest Learning Thermostat (4th gen) for eligible owners. The discount is not a universal entitlement: verify the current country, model eligibility, offer dates, inventory, HVAC compatibility, and installation requirements before removing the old thermostat.
A Matter-compatible thermostat
Matter supports thermostats and is designed to make compatible devices work across more than one smart-home ecosystem. A Matter label alone does not guarantee a drop-in installation. You still need a compatible hub or controller, an HVAC system the thermostat supports, and an app platform you intend to use.

Checks to make before buying
- Wiring and HVAC: Match terminals and system type, including heating, cooling, heat-pump, dual-fuel, or auxiliary equipment where applicable.
- Regional compatibility: Thermostat versions and installation rules can differ between North America, Europe, and other markets.
- Local fallback: Prefer a model that remains adjustable at the wall if its cloud service is unavailable.
- Update commitment: Read the manufacturer’s security-support policy. Google’s Safety Center states a minimum of five years of automatic critical security updates from the date a connected Nest device starts selling in the US Google Store; that policy does not turn an unsupported older model into a supported one.
- Subscriptions: For cameras and advanced AI features, check whether remote storage or detection features require a current subscription.
What to do with other old Nest gadgets
Nest thermostats from 2015 onward
Google’s October 2025 Home-app announcement says thermostats launched in 2015 or later remain supported in the redesigned Google Home app. Their exact controls vary by model, so check the device-specific setup and compatibility information rather than applying the early-thermostat cutoff to every Nest thermostat.
Nest Protect smoke and carbon-monoxide alarms
The support change did not make Nest Protect alarms universally unusable. Google Home can still provide smoke and carbon-monoxide alerts from Nest Protect. Separately, every Protect has a physical replacement date printed on the alarm. The second-generation Protect was described by Google in 2015 as having an up to 10-year carbon-monoxide-sensor lifetime. Replace an alarm at its stated date, even if its app connection still appears to work.

Confirm that your particular camera is eligible before starting a transfer, and review any current subscription requirement for recording or advanced detection.

Nest x Yale Lock
Google’s Home-app support announcement includes passcode management for Nest x Yale Lock. The thermostat sunset therefore does not, by itself, disable the lock. Keep the lock’s access codes and physical backup procedures documented in case an app account or network is unavailable.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Recycle instead of discarding connected hardware
Google says it can help recycle affected thermostats. Use the recycling route available in your country and follow local electronics-waste rules; collection options differ by jurisdiction. Do not place a thermostat or alarm in ordinary household rubbish when local regulations require electronics recycling.
For Nest Protect, take an expired alarm to a designated waste-collection point as directed in its user guide. Remove it from service at the printed replacement date, regardless of whether the battery or app connection still works.
Quick Recap
Choose the option that fits your household
| Choice | Best when | Main trade-off |
|---|---|---|
| Keep the affected thermostat locally | You only need wall controls and accept no remote access or future updates. | There is no app, Assistant, cloud monitoring, or security-update support. |
| Use Google’s eligible trade-in path | You want a current Google thermostat and your model, country, and HVAC system qualify. | The advertised $50 discount and availability must be verified at purchase. |
| Choose a Matter thermostat | Interoperability and the ability to change smart-home platforms are priorities. | You still need a compatible hub, HVAC fit, and platform support. |
| Recycle and replace with a non-connected thermostat | You prefer simple local operation or do not want another cloud dependency. | You give up smart-home automation and remote control. |
