Apple pushes Thread 1.4 adoption while competitors lag behind

In June 2025, it was reported that Apple is set to bring Thread 1.4 to its border routers, a significant upgrade that is expected with the release of tvOS 26 later this year. This update specifically targets the integration of various smart home devices across manufacturers by standardizing how border routers connect to existing Thread networks. However, challenges remain as major competitors like Amazon and Google are still utilizing Thread 1.3, making it uncertain when a fully unified mesh network will be available for consumers. As of January 1, 2026, Thread 1.4 will be the only certification specification available for Thread Border Routers. Apple’s commitment stands out, but a lack of widespread adoption means users may have to wait until at least 2026 for smoother interoperability in a mixed smart home environment. Concurrently, Samsung also stated that its border routers will be updated to support Thread 1.4 later this year, reinforcing the competitive landscape of smart home technology. The fragmented adoption has created a situation where users who own devices from multiple brands will experience limitations to their smart home capabilities in the immediate future, leading to possible consumer frustration and calls for quicker updates from other tech giants.
