將新的 Matter 裝置新增至住家

iOS 版 Home API 會使用 Matter 中樞將裝置委派至結構體。在調試期間,應用程式會先將指令傳送至 SDK,然後再傳送至中樞。

如要啟用 Matter 裝置,請按照下列步驟操作:

  1. 通知 Home APIs iOS SDK,準備使用 structure.prepareForMatterCommissioning() 啟用 Matter 要求。這個指令會執行以下操作:

    • 確認已授予權限。
    • 確認中樞已連上網路且可供存取。
    • 確認沒有其他正在進行的委派工作階段。
    do {
      try await structure.prepareForMatterCommissioning()
    } catch {
      Logger.error("Failed to prepare for Matter Commissioning: \(error).")
      return
    }
    
  2. 使用 MatterAddDeviceRequest() 建立要求,啟動 Apple 的 Matter 支援流程。

    let topology = MatterAddDeviceRequest.Topology(
      ecosystemName: "Google Home",
      homes: [MatterAddDeviceRequest.Home(displayName: structure.name)]
    )
    
    let request = MatterAddDeviceRequest(topology: topology)
    
  3. 使用 perform() 執行要求。如果發生錯誤,請使用 structure.cancelMatterCommissioning() 取消委派要求。

    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. Apple Developer Console 中建立 App Group ID,讓應用程式在裝置啟用時與 MatterAddDevice 擴充功能通訊。

    您也需要更新應用程式套件 ID 和佈建設定檔,才能使用這個群組 ID。

  5. 在初始化時,請設定 Home 例項以使用群組 ID。

    func application(_ application: UIApplication, didFinishLaunchingWithOptions
    launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
      Home.configure {
        $0.sharedAppGroup = "group.com.sample.app.commissioning"
      }
    
      return true
    }
    
  6. 實作 Apple 的 iOS Matter 應用程式擴充功能。

    範例程式碼顯示實作 Apple MatterAddDeviceExtensionRequestHandler API 子類別的範例。

    至少將 GoogleHomeMatterCommissionerSDK 架構新增至擴充功能目標,並覆寫三種方法來呼叫 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).")
        }
      }
    }
