It began as a ardour venture. But in a couple of years matter.js has grown past my wildest expectations, changing into the spine of the open supply Matter ecosystem, and powering the whole lot from Homebridge to openHAB, and even some business merchandise.
Ten months in the past, I joined forces with the Open Dwelling Basis to work full time as Lead Developer of Matter. Shortly after, I donated matter.js to the inspiration – giving it a brand new dwelling the place it could be safeguarded for the longer term. Collectively we introduced our plans to take Matter help in Dwelling Assistant in a totally new path: we got down to rebuild the Open Dwelling Basis Matter Server – the engine that powers Matter in Dwelling Assistant – on matter.js.
After 4 months of beta testing, with our group fixing bugs and contributing new options alongside the best way, immediately we’re thrilled to current the latest model of Matter for Dwelling Assistant! 🎉
The Open Dwelling Basis invests in essential know-how to make open alternate options potential, and our work is funded partially by everybody who subscribes to Dwelling Assistant Cloud and buys official {hardware} from our business companions. The launch of a brand new Matter expertise in Dwelling Assistant exhibits what’s potential together with your help. 💪
Presenting the matter.js plans on the Connectivity Requirements Alliance (CSA) Member Assembly in November 2025 (proper), and returning in March 2026 as an Excellent Contributor Award recipient (left).
Serving up extra with matter.js
For these new to matter.js, it’s an open supply TypeScript implementation of the Matter commonplace. I constructed it to provide builders and energy customers extra velocity and suppleness, and to make Matter higher fitted to open supply growth throughout the thousands and thousands of houses that use Dwelling Assistant. By operating Matter in Dwelling Assistant on matter.js, all of these advantages now move instantly into the platform.
This main replace brings higher stability for Matter in Dwelling Assistant, fewer bugs, and sooner start-up and restoration. It additionally comes with a model new visualization function that can assist you perceive your community (extra on that beneath 👀). And by upgrading to the Matter 1.5.1 specification (1.6 coming quickly!), we’re higher outfitted to enhance help for all new Matter gadget varieties, comparable to cameras, doorbells, and closures.
Coupled with an up to date OpenThread Border Router (OTBR) app to help Thread 1.4 in Dwelling Assistant, these adjustments mark essential steps in making Matter work extra reliably inside your setup, now and into the longer term. However don’t simply take our phrase for it – right here’s what our beta testers are saying:
“The brand new Matter Server has advanced into the last word Matter controller and troubleshooting software for energy customers, backed by an unimaginable open group that continues to push the usual ahead.”
– Ward Zhou, Good Dwelling Journalist
“The brand new matter.js server is incredible. I really like all the brand new prospects it presents. Specifically, the brand new Thread mesh view is exclusive and helps hold the Thread community below management always. The icing on the cake is that Dwelling Assistant now helps Matter 1.5.1. This implies Dwelling Assistant’s Matter implementation is as soon as once more on the forefront of the trade.”

“Becoming a member of the beta program was born as a final resort to get my Matter/Thread community going. Nevertheless it was an excellent expertise! Whereas I am under no circumstances an influence person nor programmer, I might contribute at some extent. The very brief suggestions loop and shut involvement of the developer made this a pleasant (and simple!) method to contribute to the event of the Open Dwelling.”
– Haapster, Dwelling Assistant Discord Member
It was only a matter of time
When Matter emerged a couple of years in the past, we instantly noticed its potential to form the trade for the higher. As an open commonplace that lets sensible units from totally different manufacturers converse the identical language, it represents the form of interoperable tech the Open Dwelling Basis exists to champion. So we got down to construct on it.
Simply weeks after Matter’s official launch in 2022, we added the Matter integration to Dwelling Assistant, and in 2025 each Dwelling Assistant and the Open Dwelling Basis Matter Server had been formally licensed by the Connectivity Requirements Alliance. That server was constructed with Python and the official C++ Matter SDK – a strong place to begin, however one which couldn’t hold tempo with our open supply ambitions.
Matter now runs in 38% of Dwelling Assistant situations, and ranks twelfth amongst all integrations – a transparent signal of the place the sensible dwelling world is heading. We would like that future to have fewer compatibility complications, extra gadget selection, and a sensible dwelling that simply works. This replace to Matter help in Dwelling Assistant takes an enormous step towards that imaginative and prescient.
A simple change
The brand new Matter expertise in Dwelling Assistant is delivered via the “Matter Server app 9.0” – a totally appropriate drop-in alternative for the earlier Python-based server. After you’ve up to date the app, it’s going to routinely migrate your information on the primary begin, and work in precisely the identical method that the earlier server did.
Quicker, smarter, and safer
The actual advantages kick in with each subsequent server begin and gadget reconnection. Because of a variety of optimizations, units now come again on-line a lot sooner, networks are extra responsive, and over-the-air updates are extra dependable.
Past efficiency, the brand new server additionally tightens safety. When commissioning new units, uncertified units with an official growth/take a look at certificates can now not be added out of the field, guaranteeing no malicious units are added to your Matter community with out your data. Moreover, the brand new server checks certificates revocation information throughout commissioning, including one other layer of safety.
A clearer view
Whereas the Matter Server’s internet UI acquired a variety of latest and improved options, the power to visualise your Thread or Wi-Fi networks steals the present.
Your complete community, at a look.
The visualization function attracts particulars out of your commissioned Matter units to map the community and provide insights into connection high quality. Every gadget seems as a node, with small icons indicating its position within the community – whether or not it’s a pacesetter (crown), a router (arrows), a sleepy, or one other finish gadget. The colour of the connections between nodes displays connection high quality: inexperienced is robust, orange medium, crimson weak, and grey no sign (for those who desire a deeper dive, try our GitHub documentation).
That is particularly useful for Thread networks, the place there will be a number of “hops” between a tool and the border router, and the units themselves resolve how information is routed. The place potential, border routers are additionally found and displayed, providing you with a fuller image of how your community is structured. The visualization additionally helps with Wi-Fi units, making it simpler to see which gadget is linked to which entry level, and at what sign high quality.
A basis for what’s subsequent
Graduating Dwelling Assistant to matter.js wouldn’t have been potential with out our group, who’ve helped develop Dwelling Assistant into one of many greatest sensible dwelling platforms on this planet.
With these new adjustments, we’re higher positioned than ever to make Matter in Dwelling Assistant extra approachable for all. Head to the Open Dwelling Basis roadmap so as to add your voice to what comes subsequent. We are able to’t wait to maintain constructing collectively ⚒️.
