Owners of Nest smart home devices are noticing new improvements. Google has begun rolling out Thread 1.4 to several models, including the Nest Hub and the Nest WiFi Pro. This change comes after a similar update was deployed to the Google TV Streamer in June 2026.
The update is currently being distributed automatically. Some users spotted the update online, sharing their findings on Reddit. They confirmed the change has reached the Nest Hub, the Nest Hub Gen 2, the Nest Hub Max, and the Nest WiFi Pro. These are key parts of Google’s smart home lineup.
What is Thread 1.4?
Thread is a communication protocol. It acts as the underlying layer for the Matter smart home standard, which allows devices from different companies to work together. Through a mesh network, Thread helps devices communicate wirelessly by passing signals from one to the next.
Thread 1.4 introduces better ways to share connection information. This should make it easier and more secure to add new devices to a smart home setup. The update also helps reduce delays and device dropouts.
Google is keeping it quiet
Though the change is happening, Google has not made an official statement. Some users are confused and frustrated, as they had expected a formal announcement. One Reddit user wrote, “You think they would announce this somewhere.”
