将新的 Matter 设备添加到住宅

使用集合让一切井井有条 根据您的偏好保存内容并对其进行分类。

适用于 iOS 的 Home API 使用 Matter 集线器将设备委托给 fabric。在调试期间，应用会向 SDK 发送命令，然后再将命令发送到集线器。

如需委托 Matter 设备，请执行以下操作：

1. 使用 structure.prepareForMatterCommissioning() 通知 Home APIs iOS SDK 为 Matter 委托请求做好准备。此命令将执行以下操作：

   • 验证是否已授予权限。
   • 确保集线器处于在线状态且可供访问。
   • 确保没有其他正在进行的有效配置会话。

   do {
     try await structure.prepareForMatterCommissioning()
   } catch {
     Logger.error("Failed to prepare for Matter Commissioning: \(error).")
     return
   }
   

2. 使用 MatterAddDeviceRequest() 创建请求，以启动 Apple 的 Matter 支持流程。

   let topology = MatterAddDeviceRequest.Topology(
     ecosystemName: "Google Home",
     homes: [MatterAddDeviceRequest.Home(displayName: structure.name)]
   )
   
   let request = MatterAddDeviceRequest(topology: topology)
   

3. 使用 perform() 执行请求。如果发生错误，请使用 structure.cancelMatterCommissioning() 取消配置请求。

   do {
     Logger.info("Starting MatterAddDeviceRequest.")
     try await request.perform()
     Logger.info("Successfully completed MatterAddDeviceRequest.")
     let commissionedDeviceIDs = try structure.completeMatterCommissioning()
     Logger.info("Commissioned device IDs: \(commissionedDeviceIDs).")
   } catch let error {
     structure.cancelMatterCommissioning()
     Logger.error("Failed to complete MatterAddDeviceRequest: \(error).")
   }
   

4. 在 Apple 开发者中心中创建 App Group ID，以允许应用在配置设备时与 MatterAddDevice 扩展程序通信。

   您还需要更新应用软件包标识符和配置文件，才能使用此组 ID。

5. 在初始化时，将 Home 实例配置为使用组标识符。

   func application(_ application: UIApplication, didFinishLaunchingWithOptions
   launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
     Home.configure {
       $0.sharedAppGroup = "group.com.sample.app.commissioning"
     }
   
     return true
   }
   

6. 实现 Apple 的 iOS Matter 应用扩展。

   示例代码展示了实现 Apple MatterAddDeviceExtensionRequestHandler API 的子类的示例。

   至少，请将 GoogleHomeMatterCommissionerSDK 框架添加到扩展程序目标，并替换三种方法以调用 Google Home platformHomeMatterCommissioner API。

   • commissionDevice
   • rooms
   • configureDevice

   import MatterSupport
   import GoogleHomeMatterCommissionerSDK
   import OSLog
   
   final class RequestHandler: MatterAddDeviceExtensionRequestHandler {
     // The App Group ID defined by the application to share information between the extension and main app.
     private static var appGroup = "group.com.sample.app.commissioning"
   
     ...
   
     // MARK: - Home API commissioning handlers
   
     /// Commissions a device to the Google Home ecosystem.
     /// - Parameters:
     ///   - home: The home that the device will be added to
     ///   - onboardingPayload: The payload to be sent to the Matter Commissioning SDK to commission the device.
     ///   - commissioningID: An identifier not used by the Home API SDK.
     override func commissionDevice(in home: MatterAddDeviceRequest.Home?, onboardingPayload: String, commissioningID: UUID) async throws {
       Logger.info("Commission Matter device with payload: '\(onboardingPayload)'.")
   
       var onboardingPayloadForHub = onboardingPayload
       let homeMatterCommissioner = try HomeMatterCommissioner(appGroup: RequestHandler.appGroup)
       try await homeMatterCommissioner.commissionMatterDevice(
       onboardingPayload: onboardingPayloadForHub)
     }
   
     /// Obtains rooms from the Home Ecosystem to present to the user during the commissioning flow.
     /// - Parameter home: The home that the device will be added to.
     /// - Returns: A list of rooms if obtained from the Google Home ecosystem or an empty list if there was an error in getting them.
     override func rooms(in home: MatterAddDeviceRequest.Home?) async -> [MatterAddDeviceRequest.Room] {
       do {
         let homeMatterCommissioner = try HomeMatterCommissioner(appGroup: RequestHandler.appGroup)
         let fetchedRooms = try homeMatterCommissioner.fetchRooms()
         Logger.info("Returning \(fetchedRooms.count) fetched rooms.")
         return fetchedRooms
       } catch {
         Logger.info("Failed to fetch rooms with error: \(error).")
         return []
       }
     }
   
     /// Pushes the device's configurations to the Google Home Ecosystem.
     /// - Parameters:
     ///   - name: The friendly name the user chose to set on the device.
     ///   - room: The room identifier that the user chose to put the device in.
     override func configureDevice(named name: String, in room: MatterAddDeviceRequest.Room?) async {
       Logger.info("Configure Device name: '\(name)', room: \(room?.displayName ?? "").")
       do {
         let homeMatterCommissioner = try HomeMatterCommissioner(appGroup: RequestHandler.appGroup)
         await homeMatterCommissioner.configureMatterDevice(
           deviceName: name, roomName: room?.displayName)
       } catch {
         Logger.info("Configure Device failed with error: \(error).")
       }
     }
   }
