1. Device Management

Device management mainly provides device related operations, device control, device status change monitoring, device rename, device firmware upgrade, device remove, device restoration factory settings and other operations.

TuyaSmartDeviceModel

1.1. Initialize Device

Note: you need to initialize a home instance through TuyaSmartHome, then call the interface getHomeDetailWithSuccess:failure: get the details of the home. After synchronizing the details of the home, the device can be initialized successfully.

The wrong deviceId may cause initialization failure. Then, the instance of the device returns nil

Declaration

Initialize the device class according to the deviceId.

/**
 *  Get TuyaSmartDevice instance. If current user don't have this device, a nil will be return.
 *  获取设备实例。如果当前用户没有该设备，将会返回nil。
 *
 *  @param devId Device ID
 *  @return instance
 */
+ (nullable instancetype)deviceWithDeviceId:(NSString *)devId;

Parameters

Example

Objc:

TuyaSmartDevice *device = [TuyaSmartDevice deviceWithDeviceId:devId];
device.delegate = self;

Swift:

let device = TuyaSmartDevice(deviceId: devId)
device.delegate = self

1.2. Delegate of Device

After the TuyaSmartDeviceDelegate delegate protocol is realized, user can update the UI of the App device control in the callback of device status change.

Example

Objc:

- (void)initDevice {
    self.device = [TuyaSmartDevice deviceWithDeviceId:@"your_device_id"];
    self.device.delegate = self;
}

#pragma mark - TuyaSmartDeviceDelegate

- (void)device:(TuyaSmartDevice *)device dpsUpdate:(NSDictionary *)dps {
    // DPS status of the device changes, refresh the UI
}

- (void)deviceInfoUpdate:(TuyaSmartDevice *)device {
    // Device information updates such as device name modification, device online and offline status, etc
}

- (void)deviceRemoved:(TuyaSmartDevice *)device {
    // Device removed
}

- (void)device:(TuyaSmartDevice *)device signal:(NSString *)signal {
    // Wifi signal
}

- (void)device:(TuyaSmartDevice *)device firmwareUpgradeProgress:(NSInteger)type progress:(double)progress {
    // Firmware upgrade progress
}

- (void)device:(TuyaSmartDevice *)device firmwareUpgradeStatusModel:(TuyaSmartFirmwareUpgradeStatusModel *)upgradeStatusModel {
    // Callback of device upgrade status
}

Swift:

func initDevice() {
    device = TuyaSmartDevice(deviceId: "your_device_id")
    device?.delegate = self
}

// MARK: - TuyaSmartDeviceDelegate

func device(_ device: TuyaSmartDevice?, dpsUpdate dps: [AnyHashable : Any]?) {
    // DPS status of the device changes, refresh the UI
}

func deviceInfoUpdate(_ device: TuyaSmartDevice?) {
    // Device information updates such as device name modification, device online and offline status, etc
}

func deviceRemoved(_ device: TuyaSmartDevice?) {
    // Device removed
}

func device(_ device: TuyaSmartDevice?, signal: String?) {
    // Wifi signal
}

func device(_ device: TuyaSmartDevice?, firmwareUpgradeProgress type: Int, progress: Double) {
    // Firmware upgrade progress
}

func device(_ device: TuyaSmartDevice?, firmwareUpgradeStatusModel upgradeStatusModel: TuyaSmartFirmwareUpgradeStatusModel?) {
    // Callback of device upgrade status
}

1.3. Device Control

Device control supports three kinds of channel control, LAN control, cloud control, and automatic mode (if LAN is online, first go LAN control, LAN is not online, go cloud control)

LAN Control

    [self.device publishDps:dps mode:TYDevicePublishModeLocal success:^{
        NSLog(@"publishDps success");
    } failure:^(NSError *error) {
        NSLog(@"publishDps failure: %@", error);
    }];

Cloud Control

    [self.device publishDps:dps mode:TYDevicePublishModeInternet success:^{
        NSLog(@"publishDps success");
    } failure:^(NSError *error) {
        NSLog(@"publishDps failure: %@", error);
    }];

Auto Mode

    [self.device publishDps:dps mode:TYDevicePublishModeAuto success:^{
        NSLog(@"publishDps success");
    } failure:^(NSError *error) {
        NSLog(@"publishDps failure: %@", error);
    }];

1.4. Functions of Device

The dps (NSDictionary type) attribute of the TuyaSmartDeviceModel class defines the state of the device, and the state is called data point (DP) or function point. Each key in the dps dictionary refers to a dpId of a function point, and Value refers to the dpValue of a function point. The dpValue is the value of the function point. Refer to the functions of product in the Tuya developer platform for definition of function points of products. See the following figure.

The control instructions shall be sent in the format given below:

{"<dpId>":"<dpValue>"}

According to the definition of function points of the product in the back end, the example codes are as follows.

Example

Objc:

- (void)publishDps {
  // self.device = [TuyaSmartDevice deviceWithDeviceId:@"your_device_id"];

  NSDictionary *dps;

  // Set bool dp value to true
    dps = @{@"1": @(YES)};

  // Set string dp value to "ff5500"
    dps = @{@"4": @"ff5500"};

  // Set enum dp value to "Medium"
    dps = @{@"5": @"Medium"};

  // Set number dp value to 20
    dps = @{@"6": @(20)};

  // Set byte dp value to "1122"
    dps = @{@"15": @"1122"};

  // Send multiple dp values together
    dps = @{@"1": @(YES), @"4": @"ff5500"};

    [self.device publishDps:dps success:^{
        NSLog(@"publishDps success");

    // Publish dp success. device state change will be reported from deviceDpsUpdate delegate callback.

    } failure:^(NSError *error) {
        NSLog(@"publishDps failure: %@", error);
    }];


}

Swift:

func publishDps() {
    var dps = [String : Any]()

    // dps: Please refers to the specific product definition

    device?.publishDps(dps, success: {
         print("publishDps success")

      // Publish dp success. device state change will be reported from deviceDpsUpdate delegate callback.
    }, failure: { (error) in
        if let e = error {
            print("publishDps failure: \(e)")
        }
    })
}

Note:

• Special attention shall be paid to the type of data in sending the control commands. For example, the data type of function points shall be value, and the @{@"2": @(25)} instead of @{@"2": @"25"} shall be sent for the control command.
• In the transparent transmission, the byte string shall be the string format, and all letters shall be in the lower case, and the string must have even bits. The correct format shall be: @{@"1": @"011f"} instead of @{@"1": @"11f"}

For more concepts of function points, please refer to the QuickStart-Related Concepts of Function Points

1.5. Querying Device Information

Declaration

Query single dp data.

Query the latest data of the dp from the device; those data will be called back via the - (void)device:(TuyaSmartDevice *)device dpsUpdate:(NSDictionary *)dps delegate.

Example

Objc:

- (void)queryDP {
    // self.device = [TuyaSmartDevice deviceWithDeviceId:@"your_device_id"];
    // query dp = "1"
  [self.device publishDps:@{@"1":null} mode:TYDevicePublishModeAuto success:^{
        NSLog(@"query dp success");
    } failure:^(NSError *error) {
        NSLog(@"query dp failure: %@", error);
    }];
}

Swift:

func queryDP() {
    // self.device = [TuyaSmartDevice deviceWithDeviceId:@"your_device_id"];
    // query dp = "1"
    device.publishDps([
        "1": null
    ], mode: TYDevicePublishModeAuto, success: {
        print("query dp success")
    }, failure: { error in
        if let error = error {
            print("query dp failure: \(error)")
        }
    })
}

Notes

• This interface is mainly for the dp points where the data will not be reported automatically. The dp data values for regular query can be obtained through TuyaSmartDeviceModel.dps.

    } failure:^(NSError *error) {
        NSLog(@"updateName failure: %@", error);
    }];
