低功耗门铃

更新时间:2022-02-09 03:10:49下载pdf

判断是否是低功耗门铃

根据 TuyaSmartDeviceModel 和 IPC SDK 中的接口,可以判断设备是否为低功耗设备。

示例代码

- (BOOL)isLowPowerDevice;

如果设备即是摄像机设备又是低功耗设备,可以认为设备是低功耗门铃。

唤醒休眠的低功耗设备

低功耗门铃由电池供电,为了节省电量,在一定时间内没有 P2P 连接会休眠。休眠后无法直接连接 P2P,您需要先唤醒设备,再连接 P2P 通道。使用 TuyaSmartDevice 类提供的接口来唤醒设备。

示例代码

- (void)awakeDeviceWithSuccess:(nullable TYSuccessHandler)success failure:(nullable TYFailureError)failure;

休眠设备唤醒监听

当唤醒休眠的低功耗设备返回 success 调用时,只是表示唤醒命令已经成功下发给门铃设备,并不代表门铃设备已启动。当门铃设备启动时,会通过设备功能点 TuyaSmartCameraWirelessAwakeDPName 上报 YES

示例代码

Objective C:

- (void)viewDidLoad {
		[super viewDidLoad];
	self.dpManager = [[TuyaSmartCameraDPManager alloc] initWithDeviceId:self.devId];
		self.device = [TuyaSmartDevice deviceWithDeviceId:self.devId];
		// 添加 DP 监听
		[self.dpManager addObserver:self];

	[self start];
}

- (void)start {
	if (self.isConnected) {
				[self.videoContainer addSubview:self.camera.videoView];
				self.camera.videoView.frame = self.videoContainer.bounds;
		[self.camera startPreview];
		}else if (!self.isConnecting) {
		if (self.device.deviceModel.isLowPowerDevice) {
				[self.device awakeDeviceWithSuccess:nil failure:nil];
			}
				[self.camera connect];
		self.isConnecting = YES;
		}
}

Swift:

func viewDidLoad() {
	super.viewDidLoad()
	self.dpManager = TuyaSmartCameraDPManager(deviceId: self.devId)
		self.device = TuyaSmartDevice(deviceId: self.devId)
		// 添加 DP 监听
		self.dpManager?.addObserver(self)

	self.start()
}

func start() {
	guard self.isConnected || self.isConnecting else {
			if self.device?.deviceModel.isLowPowerDevice() {
			self.device?.awake(success: nil, failure: nil)
		}
				self.camera.connect()
				self.isConnecting = true
		return
	}
	self.videoContainer.addSubView(self.camera.videoView)
	self.camera.videoView.frame = self.videoContainer.bounds
	self.camera.startPreview()
}

低功耗门铃电池管理

低功耗门铃有两种供电方式,插电和电池供电。通过 IPC SDK,您可以查询到设备的供电模式以及当前电量。您还可以设置一个低电量报警阈值,当电量过低时,触发一个报警通知。

示例代码

Objective C:

- (void)viewDidLoad {
		if ([self.dpManager isSupportDP:TuyaSmartCameraWirelessPowerModeDPName]) {
		TuyaSmartCameraPowerMode powerMode = [[self.dpManager valueForDP:TuyaSmartCameraWirelessPowerModeDPName] tysdk_toString];
		if ([powerMode isEqualToString:TuyaSmartCameraPowerModePlug]) {
						// 插电供电
		}else if ([powerMode isEqualToString:TuyaSmartCameraPowerModeBattery]) {
			// 电池供电
		}

	}

	if ([self.dpManager isSupportDP:TuyaSmartCameraWirelessElectricityDPName]) {
		NSInteger electricity = [[self.dpManager valueForDP:TuyaSmartCameraWirelessElectricityDPName] tysdk_toInt];
		NSLog(@"设备当前的电量为:%@%%", @(electricity));
	}

	if ([self.dpManager isSupportDP:TuyaSmartCameraWirelessLowpowerDPName]) {
		// 设置电量低于 20% 时,触发低电量警告
		[self.dpManager setValue:@(20) forDP:TuyaSmartCameraWirelessLowpowerDPName success:^(id result) {

		} failure:^(NSError *error) {
			// 网络错误
		}];
	}

	if ([self.dpManager isSupportDP:TuyaSmartCameraWirelessBatteryLockDPName]) {
		// 解除电池锁,以拆卸电池
		[self.dpManager setValue:@(NO) forDP:TuyaSmartCameraWirelessBatteryLockDPName success:^(id result) {

		} failure:^(NSError *error) {
			// 网络错误
		}];
	}
}

Swift:

override func viewDidLoad() {
	super.viewDidLoad()
	if self.dpManager.isSupportDP(.wirelessPowerModeDPName) {
		let powerMode = self.dpManager.value(forDP: .wirelessPowerModeDPName) as! String
		switch TuyaSmartCameraPowerMode(rawValue: powerMode) {
		case .plug: break
			// 插电供电
		case .battery: break
			// 电池供电
		default: break
		}
	}

	if self.dpManager.isSupportDP(.wirelessElectricityDPName) {
		let electricity = self.dpManager.value(forDP: .wirelessElectricityDPName) as! Int
		print("设备当前的电量为:", electricity)
	}

	if self.dpManager.isSupportDP(.wirelessLowpowerDPName) {
		// 设置电量低于 20% 时,触发低电量警告
		self.dpManager.setValue(20, forDP: .wirelessLowpowerDPName, success: { _ in

		}) { _ in
			// 网络错误
		}
	}

	if self.dpManager.isSupportDP(.wirelessBatteryLockDPName) {
		// 解除电池锁,以拆卸电池
		self.dpManager.setValue(false, forDP: .wirelessBatteryLockDPName, success: { _ in

		}) { _ in
			// 网络错误
		}
	}
}

门铃音频资源文件

使用低功耗门铃功能时,您需要下载默认资源文件(resources.zip),解压并加入工程。也可以按默认文件名,添加自定义的音频文件。
