Apple and Google are updating their smart home streaming devices to the latest Thread 1.4 specification. As first spotted by Matter Alpha and 9to5 Google, the new spec has arrived on compatible Apple TVs in the tvOS 27 developer beta and the Google TV Streamer through a software update.
Thread Border Routers Get Credential Sharing
This update lays the groundwork for these devices, which serve as Thread Border Routers, to implement Thread credential sharing. This enables them to connect more easily to an existing Thread network rather than creating their own. Thread is one of the connectivity protocols that the interoperability standard Matter runs on.
The original plan was for Thread Border Routers to work seamlessly behind the scenes, but that did not pan out. In 2024, the Thread 1.4 spec introduced a standardized way for border routers to share credentials. Two years later, with 1.4 on board, the streamers should offer a more straightforward method for users, manufacturers, and ecosystems to share credentials so they join your existing Thread network. Think of it like sharing a Wi-Fi password.
Current Status and Limitations
While the Google TV Streamer now offers the option to generate a QR code to join a Thread network, it did not work for the reporter. Although DNS discovery tools show the Apple TV is on Thread 1.4, there are not yet any options to share credentials in the current iOS and tvOS 27 developer betas. It is worth noting that 1.4 appeared in a tvOS 26 beta but was pulled before the final release.
Since there is still no developer beta for HomePod Software 27, the smart speakers are not joining the party yet. Google's Nest Hubs still have not received a 1.4 update. The reporter guesses that the Google Home Speaker will land later this month with Thread 1.4.
Positive Step Forward
The fact that the Apple TV and Google TV Streamer have Thread 1.4 at all is a big step in the right direction. To be fair, Apple and Google already handled this credential-sharing issue better than any other ecosystem, but unity here is only a good thing. Considering Samsung added support for credential sharing on its SmartThings hubs last October, and Ikea's Dirigera hub is on Thread 1.4, we are now just waiting for Amazon to get on board and update its smart speakers to the latest spec. The company has said that will happen this year.
Once Amazon updates, the major ecosystems will all be on the same version of Thread, which could bring significant improvements to Matter/Thread smart homes. The reporter expressed anticipation for seeing nine different Thread networks unified into one giant, meshy goodness.
