Apple released the tvOS 26 developer beta on June 12, and it adds support for Thread 1.4 to Apple TV 4K. This update aims to strengthen the mesh network that connects Home devices. As a result, users should see fewer dropouts at the edges of their homes and faster device response times.
Understanding Thread Protocol
Thread is an IP-based wireless protocol designed for smart home gadgets. It forms a self-healing mesh network that often outperforms Wi-Fi on range and power use. Moreover, Thread lets sensors, locks, shades, and lights talk directly to each other instead of relying entirely on a central hub.
Key Upgrades in Thread 1.4
Thread 1.4, released in September 2024, brings several quality-of-life improvements. For example, each node now gets a distinct internet path, allowing devices to fetch cloud-based features like weather-based shade adjustments. Additionally, manufacturers gain easier testing and troubleshooting tools for Thread products. Consequently, rollout and debugging should speed up for smart device makers.
Supported Devices
Apple has long used Thread in its Home products. HomePod mini, HomePod, and Apple TV 4K all act as border routers for older Thread versions. However, only Apple TV 4K in this beta now supports Thread 1.4. In addition, iPhone 15 Pro, 15 Pro Max, 16 Pro, and 16 Pro Max feature Thread radios for direct device control.
Direct Control and Continuity
Since iOS 18, iPhones could directly manage Thread accessories without a separate border router. Now, tvOS 26 enhances this by upgrading the border routers themselves. Therefore, homes with Apple TVs and iPhones should enjoy more reliable lighting, climate, and security control.
Looking Ahead
Apple plans to release tvOS 26 to all users this September. Once devices update, users will gain access to the improved mesh network right away. Ultimately, Thread 1.4 support in tvOS 26 marks a step forward in making smart homes simpler and more stable.
