The Nest Thermostat has long been one of the most popular smart home gadgets, allowing users to easily control heating and cooling while saving energy and creating a more comfortable living environment. However, Google recently revealed a significant change that will affect many households that currently use earlier Nest products. By late 2025, app support for first- and second-generation Nest thermostats will be stopped. If you are currently using one of these devices, you must understand what the change means, how it will affect you, and what your options are going forward.

In this article, we'll go over the details of the update, discuss the benefits of the Nest Thermostat 4th generation, and help you determine whether it's time to upgrade.

What Will Change in 2025 for the Nest Thermostat? 

In October 2025, Google will stop support for older Nest Thermostat units, notably the first and second-generation Nest Learning Thermostat. This implies that these devices will no longer be able to connect to either the Nest or Google Home apps.

Currently, app support enables you to

• Adjust the temperature remotely with your phone.

• Set or alter schedules.

• Integrate the thermostat with other smart home devices.

• Get energy-saving studies and recommendations.

When support ends, certain features will no longer be available for older devices. While the thermostat will still work manually—you can walk up to it and change the temperature—the smart capabilities that made Nest so famous will be removed.

Upgrade to the Nest Learning Thermostat (4th Generation)

To continue using smart features, consider upgrading to the Nest Learning Thermostat (4th generation). This variant has expanded features and is fully supported by the Google Home app. Notably, Google is providing a special discount on the fourth-generation device to affected users in the United States and Canada.

The switch to the Nest Learning Thermostat 4th Generation may have a different impact in the UAE than in the United States and Canada. UAE customers of older Nest Thermostats may not be able to benefit from the same price reductions and may face higher upgrade expenses.

How To Identify Your Thermostat Model? 

Check the model number of your thermostat to see whether this modification affects it. The first and second generations of Nest Learning Thermostats were released in 2011 and 2012, respectively. If your thermostat is one of these models, it qualifies for the upcoming modifications.

Preparing for Change

• Check your model: Check your thermostat's generation.

• Consider Upgrading: Evaluate the advantages of the Nest Learning Thermostat (4th generation).

• Stay informed: Keep an eye out for email updates from Google regarding the transition.

  By following these steps, you can ensure a smooth transition and continue to reap the benefits of a smart thermostat.

  
  

Which Features Will You Lose?

When Google removes app support for older Nest Thermostats in October 2025, the most significant impact will be the loss of their smart features. While the gadget will continue to manage heating and cooling manually, some essential functions that made the Nest Thermostat so popular will no longer be available. First, you will no longer be able to manage the remote via the app or voice assistant. This means you won't be able to change the thermostat when away from home or utilize voice commands with Google Assistant. 

Another significant alteration was the elimination of energy usage reporting, scheduling, and smart home connections. Without app compatibility, you won't be able to set automated temperature schedules, monitor how much energy your system is using, or connect your thermostat with other devices such as smart speakers, lights, or security systems.

Ultimately, the thermostat will only function as a manual device—you can still turn the dial to adjust the temperature, but all of the smart features that differentiated Nest will be removed. For individuals who rely significantly on these functions, upgrading to the Nest Thermostat 4th Generation is the best option.

Final Thoughts

The 2025 Nest Thermostat update shows how quickly smart home technology changes. While losing app support for older models can be irritating, the reality is that newer devices provide better performance, energy savings, and long-term compatibility with Google's growing smart home ecosystem.

If you're still using a first- or second-generation Nest Thermostat, switching to the Nest Thermostat 4th generation is the best way to maintain the convenience and efficiency you've come to expect. Given the cheap Nest Thermostat price and the possibility of rebates, the investment is highly worthwhile.
