In a significant announcement, Google has revealed that the first- and second-generation Nest Learning Thermostats will lose support starting October 2025, effectively disabling their connected features. This news was reported by Ars Technica, underscoring the implications for many users who have relied on these smart devices for years.

After the cutoff date of October 25, 2025, owners of these legacy devices will find that they will no longer receive important software updates nor will they be able to connect to Googles cloud services. This change means that users will lose the ability to control their thermostats via the Google Home app or through voice commands with Google Assistant. However, it is worth noting that basic functionalities such as temperature control and on-device scheduling will still be operational, albeit with limited capabilities.

The models affected by this phase-out include the original Nest Learning Thermostat launched in North America back in 2011, which was developed by Tony Fadell, a notable figure in tech known for his work on the iPod. Additionally, the 2012 successor and the 2014 model marketed for European markets are also included in this discontinuation.

For users in the United States looking to upgrade, Google is providing a financial incentive: a discount of $130 off the purchase of the fourth-generation Nest, which was released last year at a retail price of $280. In Canada, this upgrade comes with a slightly higher discount of CA$160, offering a more attractive solution for Canadian customers.

However, European customers are facing a more challenging situation. Google has officially stated that it will not be developing new thermostats compatible with European heating systems, leading to a limited array of options for those in that market. In a bid to ease the transition, European customers are instead being offered a 50 percent discount on the Tado Smart Thermostat X, a product that could serve as a suitable alternative.

This announcement comes in the wake of a larger trend within Google, as the tech giant has begun to discontinue various Nest products alongside job cuts in its platform and devices division. Notably, Google has ceased production of the Nest Protect Smoke & CO alarms and is also pulling the Nest x Yale Lock from its sales roster.

Despite the impending end-of-life for these thermostats, it is important to recognize that they have surpassed Googles standard five-year support commitment, with some models nearing 15 years of operation by the time they reach their cutoff date. Nevertheless, many Nest owners are likely to feel disappointed by the limited lifespan of a smart device that they might have expected to serve them for a longer duration.
