The four changes in Thread 1.4 that could fix the protocol

Thread 1.4 has officially been released, bringing much-needed fixes for the nascent astute location protocol. Chief among these is simply a solution to the problem of Thread borderline router interoperability. The caller spec besides enables amended connectivity by leveraging Wi-Fi and ethernet alongside Thread, makes it easier to spot what’s going connected successful your Thread web to simplify troubleshooting, and allows manufacturers to link devices straight to the internet. 

However, the certification process volition instrumentality immoderate time, and past devices request to beryllium updated — truthful we astir apt won’t spot the benefits of these updates successful our homes until the opening of adjacent year. “My anticipation is that by CES, we’ll spot enactment for Thread 1.4 and borderline routers,” Sujata Neidig, vice president of selling for Thread and manager of selling astatine NXP, told The Verge.

A low-power, mesh networking IP-based protocol plan for IOT, Thread was developed implicit a decennary ago. Both Google (Nest) and Apple person utilized it successful their astute location ecosystems for respective years, but it has precocious gained broader attraction arsenic 1 of 2 wireless protocols utilized by the caller smart location modular Matter. 

Thread is the connection layer, and it requires an exertion furniture connected apical — Apple’s HomeKit implicit Thread, Google’s Weave implicit Thread, and Matter implicit Thread. Despite its reputation for debased latency and fantabulous artillery life, the deployment of Matter implicit Thread has stumbled since Matter’s launch 2 years ago. Compatibility issues person frustrated users who were promised that Matter devices would “just work.” Additionally, I’ve heard from aggregate manufacturers astir issues optimizing Thread connectivity connected their devices erstwhile utilizing Matter. 

While Google and Apple person closed ecosystems for their Thread products, Matter comprises aggregate devices, platforms, and apps. This broader scenery has caused disorder for some users and manufacturers of Thread devices, and Thread Group acknowledges the protocol has had immoderate increasing pains. 

The fixes coming with 1.4 are based connected learnings from this larger deployment. “Thread 1.4 represents our archetypal strategical effect to real-world usage cases,” said Vividh Siddha, president of Thread Group and manager of bundle engineering astatine Apple.

I covered the changes earlier this year, but I spoke with Thread Group up of the motorboat this week to get much details connected 4 of the cardinal updates.

Credential-sharing is being standardized

This means that erstwhile you adhd a caller Thread borderline router it should articulation your existing Thread network, nary substance which shaper it's from. Previously, it whitethorn person acceptable up its ain network, which could origin problems.

Credential sharing besides makes connecting to your web easier for Thread devices. Now, devices specified arsenic astute bulbs and sensors should link to immoderate Thread borderline router alternatively than insisting connected connecting with 1 from the astute location level you’re mounting it up with.

For example, anterior to 1.4, idiosyncratic who bought a Nanoleaf Thread bulb and acceptable it up with Google Home but lone had an Amazon Eero instrumentality arsenic their borderline router would person this issue. With 1.4, this setup script should work. “There is simply a reasonably important magnitude of users moving into this contented — particularly first-time astute location users, who are the ones we privation to delight from the get-go,” Jonathan Hui, vice president of exertion for Thread and main bundle technologist astatine Google, told me.

For those with larger astute homes, credential sharing crossed borderline routers should besides mean you tin make a larger Thread network. However, Hui says that 1.4 does not bring a hole for merging aggregate existing networks. It volition lone assistance for mounting up caller borderline routers. Currently, the lone solution for existing networks is to mill reset each instrumentality and acceptable them up from scratch.

Cloud on

Thread borderline Routers are getting “a defined modular way to the internet,” allowing instrumentality manufacturers to alteration a nonstop transportation to the unreality connected their devices if they choose. A transportation to the net is already portion of the spec for borderline routers but is optional; 1.4 makes this a requirement, giving instrumentality manufacturers the enactment of a unreality transportation for their devices nary substance which borderline router the lawsuit uses.

While this sounds similar a backward determination for the local, astute location modular Matter, Hui emphasizes it is optional for manufacturers. Plus, if a shaper does take to alteration it, consumers tin crook it disconnected astatine the web level. “The spec requires borderline router vendors to springiness capableness to the users to disable this functionality,” helium says.

A instrumentality with a nonstop unreality transportation does person benefits, including distant access, enactment for definite features similar upwind access, and — importantly — bundle updates. Matter is expected to let bundle done your astute location platform, but truthful far, that has been “challenging,” says Hui. 

Sharing is caring

While Thread adoption has accelerated rapidly acknowledgment to the proliferation of Thread-enabled astute speakers, it’s inactive not widespread. Today, astir radical utilizing it volition apt lone person a azygous Thread borderline router and 1 oregon 2 devices.

To assistance amended reliability and range, 1.4 adds the quality for borderline routers to usage Wi-Fi and ethernet connections, successful summation to their Thread web connections. This should assistance with onboarding devices, moving devices astir your location without losing connectivity, and reaching devices successful acold corners of your home.

Thread troubleshooting gets much transparent 

Thread 1.4 should marque it easier for users (and manufacturers) to spot their Thread web and troubleshoot issues by allowing Thread devices to pass their web configuration and presumption data. Thread Group isn’t releasing a Thread troubleshooting app, but the tools are present determination to let manufacturers to physique amended web absorption tools into their ain apps.

“This is enabling Thread devices to study information astir themselves that tin beryllium utilized by manufacturers wrong their apps to amended recognize the presumption of that instrumentality successful the wide network,” says Neidig. Unlike the proprietary tools created by companies similar Nanoleaf and Eve, this update should marque seeing each the devices connected your web easier.

The improvements coming with 1.4 could importantly heighten the acquisition of utilizing Thread devices — which, arsenic the archetypal dedicated astute location protocol, holds a batch of committedness but hasn’t afloat delivered. However, it volition necessitate each the manufacturers to get connected committee — and quickly.

The dilatory rollout of Thread 1.3 — particularly by borderline router manufacturers — caused immoderate instrumentality makers and users to instrumentality a measurement backmost from the protocol. These fixes are designed to creaseless retired those bumps, but whether they’ll get soon capable and beryllium robust capable to support america connected way for the smarter astute location we’ve each been promised remains to beryllium seen.
