Greetings! I've added a Matter accessory via the Apple Home app. In my app, I'm attempting to commission this device and add it to my fabric. However, when I try to open the commissioning window, I receive an error stating, MTRBaseDevice doesn't support openCommissioningWindowWithDiscriminator over XPC. It appears that opening a commissioning window via an XPC connection is not yet supported. Is there another method to commission the device? Can I retrieve the setup payload from the MTRBaseDevice object or the shared MTRDeviceController? Here's the simplified version of my code: var home: HMHome // HMHome received via HMHomeManager var accessory: HMAccessory = home.accessory[0] // my Matter-supported accessory let deviceController = MTRDeviceController.sharedController( withID: home.matterControllerID as NSCopying, xpcConnect: home.matterControllerXPCConnectBlock ) let device = MTRBaseDevice( nodeID: accessory.matterNodeID as NSNumber, controller: deviceController ) device.openCommissioningWindow( withDiscriminator: 0, duration: 900, queue: .main) { payload, error in if let payload { // payload not received } else if let error { // I'm getting here "Error Domain=MTRErrorDomain Code=6 "(null)"" // and "MTRBaseDevice doesn't support openCommissioningWindowWithDiscriminator over XPC" logged in the console print(error) }

Hi everyone, I am pretty new to writing Swift and only doing it to extend a React Native App, thus my knowledge is a bit limited. I am trying to follow the example from https://developer.apple.com/documentation/mattersupport/adding-matter-support-to-your-ecosystem#Set-the-principal-class Without implementing the Extension, the Workflow starts but fails after a few minutes to add the device to Apple Home. Hence, I am currently trying to add the extension (as this is later on needed anyway to commission the device to our ecosystem). I added the class with some dummy logs to see if anything gets triggered but I am failing at registering the class as stated at https://developer.apple.com/documentation/mattersupport/adding-matter-support-to-your-ecosystem#Set-the-principal-class How is this meant to work? I guess I need to define it in info.plist but at least this did not work out: ... <key>NSExtensionPointIdentifier</key><string>com.apple.matter.support.extension.device-setup</string> <key>NSExtensionPrincipalClass</key><string>IoBrokerAddDeviceExtensionRequestHandler</string> ... Does anyone know how to register the class? Thanks in advance. Kind regards Moritz

Hi, Currently I would like to commission a thread device via MatterSupport.

I am using a Matter Device to do the OTA test with iPhone 8 Plus, HomePod mini, and the Home App. however, there is some abnormal behavior. The problem is that: The Matter device in the pop-up message is still the old firmware version after the OTA upgrade successfully. A few minutes later, the firmware version is updated in the device info but Apple Home still pop-up that a new firmware version is available for the Matter device with the same new version. When I restart the HomePod mini, no more updates are available for my device. is the HomePod cached the firmware version? The firmware version display format is incorrect? I remember the firmware format is in string e.g. 1.6.138. I could confirm this issue happened on HomePod mini V17.4. example: The old firmware version of the Matter device should be 251689472 in number and 1.5.122.0 in string. The new firmware version of the Matter device after OTA should be 1.6.138.0 in string and 268470784 in number (OTA upgrade with new firmware version) **Please let me know if more information is needed. ** Environment: iPhone 8 Plus, IOS 16.7.5 Apple HomePod Mini V17.5

In my RequestHandler.swift, this is extension of MatterAddDeviceExtensionRequestHandler After commission device is completion. I call getBaseDevice method in the MTRDeviceController. func controller(_ controller: MTRDeviceController, commissioningComplete error: Error?, nodeID: NSNumber?) { if error != nil { os_log(.default, "TrinhVM: commissioningComplete error -> \(error!.localizedDescription)") } else { os_log(.default, "TrinhVM: commissioningComplete ->\(nodeID)") chipController.getBaseDevice(1, queue: DispatchQueue.main, completionHandler: { chipDevice, error in if chipDevice == nil { os_log(.debug, "Status: Failed to establish a connection with the device") } else { os_log(.error, "Status: Success to establish a connection with the device: \(chipDevice?.description ?? "")") let onOff = MTRBaseClusterOnOff(device: chipDevice, endpointID: 1, queue: DispatchQueue.main) // Send the "on" command to the device onOff?.on { error in let resultString: String if let error = error { resultString = String(format: "An error occurred: 0x%02lx", error._code) } else { resultString = "On command success" } debugPrint(resultString) } } }) } } It's working well, the status is always "Status: Success to establish a connection with the device". And I can control the lightbulb here with chipDevice (chipDevice is MTRBaseDevice). But, after the commission device has finished in the extension, get back the application scheme. I call method: chipController.getBaseDevice(1, queue: DispatchQueue.main, completionHandler: { chipDevice, error in if chipDevice == nil { os_log(.debug, "Status: Failed to establish a connection with the device") } else { os_log(.error, "Status: Success to establish a connection with the device: \(chipDevice?.description ?? "")") let onOff = MTRBaseClusterOnOff(device: chipDevice, endpointID: 1, queue: DispatchQueue.main) // Send the "on" command to the device onOff?.on { error in let resultString: String if let error = error { resultString = String(format: "An error occurred: 0x%02lx", error._code) } else { resultString = "On command success" } debugPrint(resultString) } } }) It's always show timeout error . Mdns: Resolve failure (src/platform/Darwin/DnssdImpl.cpp:476: CHIP Error 0x00000074: The operation has been cancelled) OperationalSessionSetup[1:0000000000000015]: operational discovery failed: src/lib/address_resolve/AddressResolve_DefaultImpl.cpp:119: CHIP Error 0x00000032: Timeout Creating NSError from src/lib/address_resolve/AddressResolve_DefaultImpl.cpp:119: CHIP Error 0x00000032: Timeout (context: (null)) "Failed to establish a connection with the device Optional(Error Domain=MTRErrorDomain Code=9 \"Transaction timed out.\" UserInfo={NSLocalizedDescription=Transaction timed out.})" I don't know why the same method, works in RequestHandler.swift but not in AppScheme. Any support for this issue. Thank and best regards.

Does anyone know if this is even supported at the moment? I've tried pairing a sample light application based on Silicon Lab's EFR32 but it's unable to find the OTBR on the network. [module](GitHub - SiliconLabs/matter: Matter is creating more connections between more objects, simplifying development for manufacturers and increasing compatibility for consumers, guided by the Connectivity Standards Alliance.) I'm also using the RaspberryPi 4/RCP combination as directed by Silicon Lab's documentation. I have no problems pairing the devices to the OTBR directly through its chiptool interface but Home isn't discovering the Thread network or showing me options to add the OTBR devices. I'm currently running iOS 16.1 beta on my iPhone and I'm using a HomePod Mini which is on version 16.0 and has the HomeKit Matter Support profile installed.

Hi, I am working on developing a MATTER device, for which I am using iPhone and Homepod mini. How do I capture the debug logs from Homepod Mini

My matter accessory define an endpoint of type light, with a custom cluster. if I connect my accessory using Home app, I'm I supposed to find HMService/HMCharacteristic corresponding to my custom matter cluster? Is there any requirement on the custom cluster to have it visible in HomeKit ? Thanks.

When the Homekit device is added to the home app and the device settings interface is opened, the supplier app will be displayed. We are currently developing a Matter product and would like to implement this feature. We consulted with the Matter testing agency and they said they need to communicate with Apple. However, they did not find a solution after consulting with Apple customer service. No one knows how to do it?

How to commission a device to our fabric after adding it using Matter.Support We have the following configuration: eero border router our own thermostat device that we are developing no home pod or home TV are used We have followed this guide https://developer.apple.com/documentation/mattersupport/adding-matter-support-to-your-ecosystem and implemented Matter Extension, as Matter.Framework is no more allowed to pair device. In Matter Extension the following callbacks are fired: override func selectThreadNetwork(from threadScanResults: [MatterAddDeviceExtensionRequestHandler.ThreadScanResult]) async throws -> MatterAddDeviceExtensionRequestHandler.ThreadNetworkAssociation override func commissionDevice(in home: MatterAddDeviceRequest.Home?, onboardingPayload: String, commissioningID: UUID) async throws In our demo app the following function completes without errors try await request.perform() The thermostat device seems to be successfully commissioned. In https://developer.apple.com/documentation/mattersupport/adding-matter-support-to-your-ecosystem there is a comment that says: Use Matter.Framework APIs to pair the accessory to your application with the provided onboardingPayload. How should this thing be done ? We tried to start the matter controller in the old way: func start() -> Bool { if (self.matterController == nil) { let storage = MatterStorage.shared let factory = MTRDeviceControllerFactory.sharedInstance() let factoryParams = MTRDeviceControllerFactoryParams(storage: storage) do { try factory.start(factoryParams) } catch { return false } let keys = FabricKeys() let params = MTRDeviceControllerStartupParams(signing: keys, fabricId: UInt64(fabricId), ipk: keys.ipk) params.vendorID = NSNumber(value: self.vendorId) self.matterController = try? factory.createController(onExistingFabric: params) let controllerNid = self.matterController?.controllerNodeID if (self.matterController == nil) { self.matterController = try? factory.createController(onNewFabric: params) } } return (self.matterController != nil) } Certificate are generated locally as in Matter Darwin example. We tried to call let params = MTRCommissioningParameters() matterController?.commissionNode(withID: NSNumber(value: self.deviceNid), commissioningParams: params) in commissionDevice of Matter Extension but we get error: Invalid object state.

func perform() async throws What are the abnormal errors thrown by the above ? Can you provide a clear list? error:Error Domain=com.apple.MatterSupport Code=1 "(null)" Where can I find the error information in the document? MatterSupport / MatterAddDeviceRequest / perform() What does this error mean: Error Domain=com.apple.MatterSupport Code=1

I created a Matter device with a fan endpoint with fan_control attribute. When I setup this device via Google Home, I see the percent control for the fan. However, when I setup via the iOS Home app, I only see an on/off switch. Is the fan_control.percent_current Matter attribute supported? Or any of the fan_control attributes?

I'd like to learn how a Matter "Binding" can be created on iOS, e.g. via the "Matter" Framework. I'm aware of the Matter Framework "Documentation" here. But since it's missing any real description or documentation it's not helpful to me atm. Any examples/ tutorials/ explanations are greatly appreciated.

I've been getting into Matter framework and succeeded to add a matter device into Apple Home app. Then, I use a HomeKit base app to get that device and would like to control that device directly through Matter framework. This is how I create a MTR Device Controller static func create(withHmAccessory hmAccessory: HMAccessory, ofHome hmHome: HMHome) -> HomekitLockAccessory { if #available(iOS 16.4, *) { let matterNodeId = hmHome.matterControllerID as NSCopying let controller = MTRDeviceController.sharedController( withID: matterNodeId, xpcConnect: hmHome.matterControllerXPCConnectBlock ) return MatterHomekitLockAccessory(hmAccessory: hmAccessory, controller: controller) } return HomekitLockAccessory(hmAccessory: hmAccessory) } the controller never gets running and I'm not able to get that controllerNodeId from it. Here is error log

How to set matter device endpoints default name? eg. I have Light Panel with 2 endpoints. endpoint 1 name: Open; endpoint 2 name: Close; I've tried FixedLabel, but it not work.

If I prefer for Google to not have access to my data, passwords, and passkeys when possible. Then what is exactly access when using devices via Matter? Does any data pass through even when not using Google services?
