It began as a ardour venture. Nonetheless, after a couple of years matter.js has grown far past my expectations and has develop into the spine of the open supply Matter ecosystem, powering every thing from Homebridge to openHAB and even some industrial merchandise.
10 months in the past I open home foundation Working full-time as a lead developer at Matter. Shortly thereafter, I donated matter.js to the Basis, giving it a brand new residence the place will probably be protected for the foreseeable future. collectively we announced our plans To take Dwelling Assistant’s Matter assist in a complete new course, we got down to rebuild the Open Dwelling Basis Matter Server (the engine that powers Matter in Dwelling Assistant) on high of matter.js.
It went via 4 months of beta testing, with the neighborhood fixing bugs and delivering new options alongside the best way. Right this moment, we’re excited to announce the most recent model of Matter for Dwelling Assistant. 🎉
The Open Dwelling Basis invests in important know-how that permits open options, and our work is funded partially by all of our subscribers. Home Assistant Cloud purchases official hardware from commercial partners. The launch of the new Matter experience in Home Assistant shows what’s possible with support. 💪

Provide more services with matter.js
For first-time users matter.jswhich is an open supply TypeScript implementation of the Matter customary. I constructed this to present builders and energy customers extra pace and adaptability, and to make Matter higher fitted to open supply improvement within the thousands and thousands of properties that use Dwelling Assistant. Run duties with Dwelling Assistant matter.jsall these advantages now movement immediately into the platform.
This main replace improves the soundness of Matter for Dwelling Assistant, reduces bugs, and hurries up startup and restoration. It additionally comes with all-new visualization options that will help you perceive your community (extra on that beneath 👀). And by upgrading to Matter 1.5.1 Specifications (1.6 will be released soon!), we’re prepared to enhance assist for all new Matter system varieties, together with cameras, doorbells, and closures.
These adjustments, mixed with an up to date OpenThread Border Router (OTBR) app that helps Dwelling Assistant Thread 1.4, symbolize vital steps to make sure Matter works extra reliably inside your setup, now and sooner or later. However do not simply take our phrase for it. This is what our beta testers must say:
“The brand new Matter Server has advanced into the final word Matter controller and troubleshooting instrument for energy customers, supported by an extremely open neighborhood that continues to advance requirements.”
– Ward Zhou, good residence journalist
“The brand new matter.js server is nice. I really like all the brand new prospects it affords. Particularly, the brand new Thread mesh view is exclusive and helps us preserve our Thread community underneath management. Even higher, Dwelling Assistant now helps Matter 1.5.1, which suggests Dwelling Assistant’s Matter implementation is as soon as once more on the forefront of the trade.”
– hoppel118, Dwelling Assistant Discord member
“Collaborating within the beta program took place as a final resort to get my matter/thread community up and working, but it surely was an excellent expertise. I am not an influence consumer or a programmer in any respect, however I used to be in a position to contribute to some extent. The very brief suggestions loop and shut developer involvement made this an excellent (and straightforward!) option to contribute to Open Dwelling’s improvement.”
– Haapster, Dwelling Assistant Discord Member
it was solely a matter of time
When Matter arrived a couple of years in the past, we instantly acknowledged its potential to form the trade for the higher. It’s an open customary that enables good gadgets from completely different manufacturers to talk the identical language, and represents the interoperable know-how that the Open Dwelling Basis exists to champion. So we began constructing on that.
Only a few weeks after Matter was formally launched in 2022. Integrate Matter with Home Assistant and both in 2025 home assistant and Open Dwelling Basis Matter Server have been formally licensed by the Connectivity Requirements Alliance. The server is in-built Python and Official C++ Matter SDK – It was a strong start line, but it surely didn’t sustain with our open supply ambitions.
An issue has occurred 38% of Home Assistant instancesranks twelfth amongst all integrations. This can be a clear indication of the place the good residence world is heading. We would like fewer compatibility points, extra system selection, and a well-functioning good residence. This replace to Matter assist for Dwelling Assistant takes an enormous step towards that imaginative and prescient.
simple swap
Home Assistant’s new Matter experience is delivered through the Matter Server app 9.0, a drop-in replacement that is fully compatible with previous Python-based servers. When you update your app, it automatically migrates your data on first launch and works exactly like your previous server.
Faster, smarter and safer
The real benefit will be seen on each subsequent server startup and device reconnection. Thanks to various optimizations, devices come back online faster, network responsiveness is improved, and over-the-air updates are more reliable.
The new server not only improves performance, but also security. When commissioning a new device, you can no longer simply add an uncertified device with official development/test certificates, ensuring that malicious devices are not unknowingly added to the Matter network. Additionally, new servers check certificate revocation data during commissioning, adding another layer of protection.
clearer vision
Among the many new and improved features added to Matter Server’s web UI, the ability to visualize threads and Wi-Fi networks stands out.
See your entire network at a glance.
Visualization capabilities pull details from delegated Matter devices to map the network and provide insight into connection quality. Each device is displayed as a node with a small icon indicating its role in the network, such as leader (crown), router (arrow), sleeper, or another end device. The color of the connections between nodes reflects the connection quality. Green is strong, orange is medium, red is weak, and gray is no signal (if you want to know more, GitHub documentation).
That is particularly helpful for threaded networks, the place there will be a number of “hops” between a tool and a border router, and the system itself decides how the info is routed. If potential, border routers are additionally found and displayed to present you a greater thought of how your community is configured. This visualization can also be helpful for Wi-Fi gadgets, making it simple to see which gadgets are linked to which entry factors and with what sign high quality.
Basis for the subsequent step
Graduating Home Assistant to matter.js would not have been possible without our community, which has helped grow Home Assistant into one of the world’s largest smart home platforms.
These new changes make it more advantageous than ever to make Matter in Home Assistant more approachable for everyone. heading to Open Home Foundation Roadmap Add your voice to what comes subsequent. I can’t wait to proceed constructing collectively ⚒️.
