Apple TV Gets Thread 1.4 Update with tvOS 26: What It Means for Your Smart Home
Apple is finally bringing the long-anticipated Thread 1.4 update for Apple TV with the launch of tvOS 26 this fall. If you're someone who relies on your Apple TV 4K or HomePod to manage smart home devices, this is a major upgrade worth paying attention to. Thread 1.4 addresses one of the biggest frustrations users face today—fragmented smart home networks caused by incompatible Thread routers. With this new version, Apple TV will help unify your devices under a single, more efficient mesh network. This change is set to significantly improve reliability, speed, and automation potential across your smart home.
Why the Thread 1.4 Update for Apple TV Matters
Thread is a low-power, low-latency networking protocol designed specifically for smart home devices. Prior to Thread 1.4, devices from different brands often created separate mesh networks, leading to delays and dropped connections. The Thread 1.4 update for Apple TV fixes this problem by allowing all Thread-enabled devices to connect through one shared network—even when they come from different manufacturers.
That’s a big win for Apple users. Since Apple TV 4K and HomePod both act as Thread border routers, they’ll be able to unify your network without any extra effort from your side. The update also allows direct internet access for Thread devices. That means your smart lights can now react instantly to things like real-time sports scores or changing weather conditions—without relying on a third-party server or extra cloud configuration.
tvOS 26 and HomePod Software 26 Will Both Support Thread 1.4
The upcoming tvOS 26, currently in beta after Apple’s WWDC 2025 event, confirms built-in support for Thread 1.4. Since HomePod runs a forked version of tvOS, users can expect HomePod Software 26 to include the same upgrade. Apple’s integration of this protocol strengthens its position in the Matter smart home alliance, reinforcing seamless compatibility between Apple devices and a growing list of smart home brands.
As Apple TV and HomePod continue to serve as home hubs within the Apple ecosystem, this update means users can expect better responsiveness, fewer disconnections, and faster communication between devices. Whether you're automating lighting routines or managing smart security systems, Thread 1.4 improves the overall experience by making your network faster and more reliable.
What to Expect from Thread 1.4 and When You'll Get It
Originally released by the Thread Group in September 2024, Thread 1.4 brings several improvements for both users and developers. Besides consolidating networks and adding internet access, it also introduces advanced diagnostic tools and better visibility into device behavior—making it easier to troubleshoot any hiccups. Apple is ahead of the curve in adopting this new standard, while competitors like Google and Amazon are reportedly planning to follow in 2026.
The Thread 1.4 update for Apple TV is expected to officially roll out in September 2025, coinciding with the public release of tvOS 26. If you already own a second-gen Apple TV 4K or a newer HomePod, you won’t need any new hardware—just make sure to update your devices when prompted. This shift could redefine how you interact with your smart home, providing a smoother, faster, and more integrated experience.
Apple’s Smart Home Future Looks Stronger Than Ever
By embracing the Thread 1.4 protocol, Apple is sending a strong message: smart homes should be simple, fast, and reliable. With the Thread 1.4 update for Apple TV and HomePod, users gain more control, enhanced automation capabilities, and improved compatibility across their devices. The update brings Apple in line with the future of smart home networking, giving users the confidence to build out their smart setups without the headaches of compatibility issues or sluggish responses.
Whether you're already deep into your HomeKit ecosystem or just starting out, this is a meaningful upgrade that enhances everyday convenience. And with Matter and Thread becoming industry standards, Apple's early adoption gives you a head start on a truly connected home.
