Starting January 1, 2026, Thread 1.4 becomes the Thread Group's only certified standard, bringing a crucial new capability called credential sharing. Devices from different manufacturers can now securely join the same mesh network -- an Amazon Echo Show and an Apple HomePod mini in the same house will both be able to control the same Nanoleaf lightbulb. This marks a significant departure from Thread 1.3, released in 2022, where each brand's mesh network connected only to devices from that same brand.
The Thread Group launched in 2014 as a coalition led by Arm, Google's Nest Labs, and Samsung, later welcoming Apple and Amazon into the fold. Thread 1.4 handles low-power smart home devices and sensors, but homes also need high-bandwidth connections for laptops and phones. Wi-Fi 7 mesh serves that purpose and the Matter protocol acts as a translation layer between the two different mesh networks. Both Wi-Fi 7 and Matter arrived in products on store shelves in 2025.
