The standards group behind the Matter smart home interoperability protocol has delayed the release of the specification by three months, extending it until the fall of this year. In a blog post, the Connectivity Standards Alliance (CSA) explains that because there are so many interested parties, testing among all of them has become more complicated, and the organization has decided to add another testing event.
The news means the delay of Matter-certified products until at least the fall, and likely longer, especially for products whose companies have not been building them toward the spec from the beginning. As a journalist — and as a consumer — who has been telling everyone I know to wait until this summer to plan their smart home device purchases, this news is a bummer.
Indeed, the longer it takes for Matter to be released, and the more expectations consumers have about its impact, the more confident I am that implementing Matter will become both essential and, at the same time, less beneficial for device makers.
Such delays have been commonplace since the beginning. Matter was announced in December 2019 as Project CHIP, and the companies involved promised that a standard would be out in a year’s time. That was crazy ambitious, especially after the pandemic hit. And yet, with every delay the CSA, which is the organization behind Matter (formerly the Zigbee Alliance), touted that it was pulling together an ambitious effort and it was still one of the fastest and most comprehensive standards efforts out there.
At the time this was true, but two and half years later, the messaging has shifted. No longer content to tout its rapid-fire standard-setting activity, the CSA started talking about how many companies were participating and how it was going to release a complete software development kit (SDK), not just a written spec. Now the messaging is focused on how many companies have gotten involved (more than 450 at the moment) and how the addition of more chip and OS providers has complicated the testing process.
This messaging is consistent across all of my conversations with people involved in the standard, so I believe their rationale for the delay. But in many respects, this is a problem of the CSA’s own making.
When Project CHIP launched, it promised a way to make the smart home interoperable. In 2019, consumers were struggling to figure out which light bulbs to buy so that they would work with their respective light switches or digital assistants. Some products worked with Alexa, Google, or Samsung, and others were HomeKit-certified.
Consumer confusion led to people ditching their smart home setups and returning products. That’s why Apple, Amazon, Google, and Samsung decided to launch something to make the smart home “interoperable.” The idea immediately caught fire and many device makers, the tech media, and others jumped on the bandwagon. I was one of them. And I still have hopes that Matter will improve the smart home.
But the world has changed a lot since December of 2019.
The smart home is still a mess in 2022, but consumers kept buying connected devices and figuring out how to make them work. Climate change and the pandemic have changed the reason many people are investing in smart home products. Security and convenience are still important, but managing indoor air quality and helping remote parents age in place have also driv
The smart home is still a mess, for one thing. But consumers kept buying connected devices and figuring out how to make them work. Meanwhile, climate change and the pandemic have altered the reasons many consumers are investing in smart home products. To be sure, security and convenience are still important, but managing indoor air quality and helping remote parents age in place have also driven people to adopt smart home devices. And big smart home players such as Google, Amazon, and Apple have continued to build out their ecosystems and add use cases for the smart home that go far beyond turning on a light with your voice.
These trends have helped make Matter less beneficial than it might have been two years ago. On one hand, I am surprised by what people think Matter will do, and find myself constantly reminding them that it won’t, for example, help with video cameras or video doorbells because a video interoperability standard is just too much, or pointing out that their appliances aren’t part of any Matter integration. On the other hand, I’m watching the big-name players that originally launched the standard push their platforms far beyond turning on lights and into services tied to security, energy efficiency, and aging in place.
For consumers, Matter remains a holy grail that they hope will “fix” all of the difficulties they have with the smart home. But for the big smart home players, Matter is already in their rear-view mirror as they build services reliant on devices that aren’t even part of the Matter spec. This isn’t to say that I think Matter is no longer important, but that any company betting on Matter as part of their business strategy needs to understand the role it’s likely to play.
Device makers have always faced a double-edged sword when it comes to Matter. For many makers of standalone devices such as locks and light bulbs, Matter will turn their product into commodity. For example, consumers who buy a Matter-certified lock will know it works with any Matter-certified digital assistant and other Matter-certified gear. So consumers will no longer have to pick among the two or three locks that work with, say, HomeKit if they are an Apple user. They will instead be able to choose from a bunch of Matter-certified locks. Device makers are reacting to this potential commodification with denial, weird additional features that require a consumer to download an app, and efforts to make specialized software features that set their products apart from the crowd. But if they don’t implement Matter, they risk making their products irrelevant.
I also suspect most companies pursuing Matter are not fully aware of how quickly it could commoditize their business.
And even as CSA members work toward Matter, companies such as Apple are launching features such as Home Key and HomeKit Secure Video, which create a new layer of services that require customer integrations that Matter was supposed to do away with. Another example might be Amazon’s Alexa Together service, which involves Echo devices and associated health products and sensors to help with aging in place. Matter doesn’t even support emerging device categories such as indoor air quality monitors or energy storage systems.
So even as we await the coming of the complete Matter standard in the fall, it feels like Matter will become the basic infrastructure underlying many smart home devices, but it’s also not going to deliver the smart home people are dreaming of today.
I’m still eager for the implementation, and can’t wait to get my questions about how it will work answered, but I’m also clear-eyed about how Matter will ultimately fit into an intuitive smart home or a home with ambient intelligence. It will be essential, but it also will become commodity infrastructure, as opposed to a holy grail that will fix all problems.

Interesting article! I’m sure you’re right that many customers are getting better at figuring out what will work for them, and since most ecosystems are offering more and more devices, the problem is a bit less acute than it used to be.
That said, every single month there are questions over at the SmartThings forum from people who have bought either a light switch or a lightbulb and can’t figure out how to get it to work with SmartThings. And the answer all too often is that it doesn’t, or at least it doesn’t without custom code.
And I know a lot of people with HomeKit setups who have high hopes that Matter implementation will bring them a whole bunch of new candidate devices to choose from.
So I don’t think the issue has gone away, although people may be looking at different aspects of it.
As you note, we will just have to wait and see what solutions Matter will actually deliver. But I do think some of the problems are still real.
Platforms that try to offer the maximum number of integrations, particularly those without an enforced logo program ( like SmartThings), do still have users who feel confused about pre-purchase decisions. And platforms like HomeKit which are currently quite restrictive about which devices will work have users who are hoping for many more device options. I also think that the number of “regular customers“ who want devices that will work with both HomeKit and Alexa is much higher than anyone expected a few years ago.
Choice is good, and one thing Matter has promised all three of these groups is more choice. Whether it can deliver is a question only time will answer.

All these delays could be resolved, if CSA and Matter first got the big three partners, Apple, Amazon and Google to talk to each other directly.
“I have these Thread plugs and bulbs I want to share with you.”
“Great, here’s my Zigbee devices.”
“Should we tell google?”
“Nah She’ll figure it out eventually.”
“hah hah hah, doubt it.”

What all could go wrong with Matter?
Matter is a union of Thread and Zigbee’s Cluster Library, with a governing process for how a device are added to a network. Thread loosely replaces what was Zigbee IP, and is publicly available as “Open Thread”.
Open Thread is a stack of software that implements 6lowpan, aka IPv6. Many of the scenarios that I have seen that talk about how Matter will interoperate rely either on IPv6 support that, home routers/providers do not support, or the lack of IPv6 security in most home environments. If you look at Open Thread’s documentation for border routers it states up front that it will not work if basic IPv6 security features like RA guard have been deployed.
The application layer is essentially the Zigbee Cluster Library. In order to generate templates for ZCL you use the ZAP tool. As a developer? ZAP comes across as something designed in the 90’s, it has none of the gains that are found in modern templating engines. If you want more information about ZCL you will need to google for it, the link on the Matter website has been broken for at least a few weeks.
Tying Matter to what is essentially Zigbee is great for those folks who have developed Zigbee devices, but for everyone else? It is a standard.
The one shining bit of Matter that is nice for consumers is around how devices are commissioned, aka added, to the network. With the exception of Apple’s HomeKit, the other solutions on the market have been pretty hodgepodge. Every Zigbee device has its own quirks, and up until Z-Wave added SmartStart, it wasn’t much better.
I haven’t seen anything in Matter which talks about decommissioning, aka reset’ing a device, but I hope they have defined this process as well. Anyone who has deployed a home automation device knows, or will learn, at some point you will probably need to reset a device. Some devices create their own little special versions of hell in order to reset them.
FWIW I have no affiliation with any company/access to Matter specifications/any information that cannot be found from googling/github repositories; I am currently employed as a pandemic-parent-small-child-caregiver. Apologies for any Siri dictation errors.
