Hi, The WWDC2021 Video Add support for Matter in your smart home app has a bunch of code examples referencing APIs that are no longer present or deprecated, e.g. this one. Unfortunately the documentation doesn't give any hint on the replacement APIs. Most of them are to be found in HMMatter* objects. But in the video at 14:27 an API for CHIPDeviceController is shown. Unfortunately that one cannot be found anymore. Does anybody know how to achieve the described task (managing state and control of a matter accessory)

I'm looking for a tutorial or documentation on HMMatterRequestHandler. I'm aware of the brief mentions in wwdc21-10298 but it's not sufficient. Is there any tutorial/ more extensive documentation?

I'm trying to commission a matter device via HMAccessorySetupRequest.performMatterEcosystemAccessorySetup. After scanning the QR code via the system provided UI the app shows a system popup: Additional Setup Required This accessory required additional setup. Refer to the manufacturer's guide for more information Unfortunately there's no further information. Did anybody succeed in using this API and could assist?

Hi, I commissioned an ESP32C3 device running Matter using the Home app. The iPhone is on iOS version 16 beta 2. For this I used the all-clusters-app/esp32 example from the connectedhomeip repo. Commit ID for connectedhomeip: cfc35951be66a664a6efdadea56d1b8ea6e63e96 I cannot on the accessory screen see any option to create matter groups. Is there any such option available on the home app? Thanks, Ajay Gantayet

Calling setupManager.addAndSetUpAccessories(for: topology) [CHIPAccessoryServer] CHIP Accessory pairing failed before network provisioning: Error Domain=CHIPErrorDomain Code=1 "Undefined error:50."

Symbol not found: OBJC_CLASS$_HMCHIPServiceHome Expected in: /System/Library/Frameworks/HomeKit.framework/HomeKit HMCHIPServiceHome(uuid: UUID(), name: "Scott's") works fine in iOS 15.0 but all of the 15.1 betas (1,2,3,4) have had this issue preventing initializing home structures.

We're trying Matter devices on HomeKit but currently using ESP32 DevKits except the M5Stack. It wasn't really mentioned in the Enabling Matter PDF that only the M5Stack is supported but there's a preference for it for testing? I have tried building the firmware for an ESP32-DevKit and I keep getting 'Unsupported setup code' despite tweaking the vendor and product id. Haven't checked the code yet if there's just M5Stack specific code support for HomeKit provisioning but throwing this question either way here.

The documentation for HMCHIPServiceRequestHandler mentions having the NSExtensionPrincipalClass inherit from HMCHIPServiceRequestHandler. Is there a NSExtensionPointIdentifier that should be set to enable the HomeKit Matter extension? Currently, my extension is not being called when trying to set up a new Matter device using HMAccessorySetupManager and I'm not sure why. ☹️ The latest Xcode 13 Beta does not yet offer a HomeKit extension template when creating a new target, so I'm not sure how to check if there's something I'm missing in the NSExtension dictionary in the extension's Info.plist. Thanks!

let setupManager = HMAccessorySetupManager() let homeTopology = HMCHIPServiceTopology(homes: homes) setupManager.addAndSetUpAccessories(for: homeTopology, completionHandler: { error in if let error = error { print(error) } }) when calling the function 'setupManager.addAndSetUpAccessories(for: homeTopology)', an error log occurs. Error Domain=HMErrorDomain Code=48 "Operation is not supported." UserInfo={NSLocalizedDescription=Operation is not supported.} Any ideas what could cause this? Is this function not working yet because it is currently beta? Or, did i use the function wrong?
