Home Assistant’s Matter Server 1.5.0 beta updates its Matter.JS engine and adds a dedicated camera API with two-way audio, custom support for Aqara’s FP400 sensor and IKEA thermostats, and faster offline detection. The release is not yet stable, and several features also need Home Assistant Core changes before they are broadly available.

The Open Home Foundation’s Matter Server 1.5.0 beta adds a dedicated camera API with two-way audio, support for Matter 1.6.1 features, and custom handling for upcoming Aqara and IKEA hardware. The update matters to Home Assistant users because it expands what the platform’s Matter controller can manage, although the release is still in testing and some capabilities require additional Home Assistant Core work.

According to the Matter Server 1.5.0 changelog, the server moves to the Matter.JS 0.18.0 engine and introduces official Matter 1.6.1 support. The protocol work establishes a foundation for Groupcast, which allows commands to be sent to groups of devices rather than addressed one by one. The release notes describe this as groundwork; they do not establish that every Home Assistant group command will immediately use multicast or that users will see a specific response-time improvement.

The update’s camera changes add WebSocket Schema version 14 and a dedicated API for managing WebRTC sessions and stream negotiation. A new talkback: true option lets compatible Matter cameras and video doorbells send audio from a Home Assistant client back through the device. The source names the Aqara Camera Hub G350 as an example. The update also addresses some WebRTC session drops and adds error codes intended to make stream problems easier to diagnose.

For device support, the server adds custom-cluster definitions and Python client support for Aqara’s Spatial Multi-Sensor FP400, including clusters tied to sensing configuration, radar sensing and occupant location. That enables functions such as detection zones and target-position events over Matter, according to the report. IKEA’s LILJEBAGGE radiator thermostat gains support for its custom ValveCalibration cluster and a dashboard control panel for calibrating compatible valves. The update also removes a fixed three-minute wait before unreachable devices are marked offline.

More Matter Devices, More Camera Control

The release extends Matter beyond basic device commands in two practical areas: camera interaction and manufacturer-specific features. Camera talkback could let users speak through supported cameras or doorbells from Home Assistant clients, while the Aqara and IKEA custom-cluster additions expose functions that the standard Matter feature set may not cover.

Groupcast support could also matter for homes with multiple lights or other grouped devices. The report says Home Assistant has handled group actions through sequential commands, which can make devices react at slightly different times. Matter 1.6.1 provides a protocol-level basis for multicast group messaging, but the beta announcement alone does not confirm when that change will reach users’ everyday automations. Faster offline reporting may help users distinguish a reachable device from one that has stopped responding, though the release notes do not quantify the change in detection time.

From Matter Support to Device Features

Home Assistant uses the Matter Server as the controller between the platform and Matter devices. Matter provides shared standards for connected-home products, but manufacturers can also use vendor-specific clusters for features that are not represented by common device functions. That is why server-side support for Aqara’s sensing controls and IKEA’s valve calibration can affect what users can access even when a device already connects over Matter.

The Connectivity Standards Alliance released Matter 1.6.1 in September, according to the source report. The update includes Groupcast being promoted from provisional status and separate volume and mute controls for doorbell chimes. Matter Server 1.5.0 is a beta implementation step, not a statement that every Matter 1.6.1 capability is already available in Home Assistant’s stable release.

The same server update includes management changes beyond the headline features. Its network graph adopts clearer Thread role labels, the Door Lock panel can create guest PIN codes with expiration settings, and commissioning details such as discriminator and vendor and product IDs are shown when opening a pairing window. Interactive panels are also added for device categories including robot vacuums, ovens, EV chargers and media players.

Beta Limits and Compatibility Questions

The source says the Matter Server 1.5.0 release is in beta and is expected to reach the stable add-on soon, but it gives no firm release date. It also says most new features require work in Home Assistant Core to become more accessible. The report does not specify which features will be usable immediately through existing interfaces or when those Core changes will arrive.

Compatibility will depend on the specific camera, thermostat, sensor, server version and client. The source identifies example Aqara and IKEA products but does not provide a full compatibility list or testing results across hardware revisions. It also offers no measured figures for group-command timing, offline detection, or how many camera clients will support talkback at launch.

Stable Release and Core Support

Home Assistant users can opt into the Matter Server beta through the server settings, according to the source report. The next milestones are a stable add-on release and the Home Assistant Core changes needed to expose more of the new functions through the broader platform. Users who rely on stable smart-home operations may prefer to wait for those releases and check device compatibility before enabling beta software.

Further release notes should clarify the stable rollout schedule, which features will be available in Home Assistant interfaces, and how broadly Groupcast and camera talkback work across supported devices. Until then, the confirmed development is the server-side beta update, not a universal change to every Matter device or Home Assistant installation.

Key Questions

Is Matter Server 1.5.0 available as a stable release?

No. The source report says version 1.5.0 is in beta and is expected to roll out to the stable add-on, but it does not give a release date.

What does camera talkback add?

A new talkback: true option allows audio to be sent from a compatible Home Assistant client through a supported Matter camera or video doorbell. Device and client compatibility will determine whether the feature works in a particular setup.

Which Aqara and IKEA devices are mentioned?

The report names Aqara’s Spatial Multi-Sensor FP400 and IKEA’s LILJEBAGGE radiator thermostat. The server adds custom-cluster support for sensing features on the Aqara device and valve calibration on the IKEA thermostat.

Does Matter 1.6.1 mean grouped lights will respond instantly?

No such measured outcome is confirmed. The update lays groundwork for Groupcast, which can send commands to a group, but the source does not report a performance test or confirm when Home Assistant will use it for all group actions.

What should users expect next?

The beta is expected to be followed by a stable Matter Server add-on release, with further Home Assistant Core work needed for broader access to many features. No specific stable-release date is provided.
