Group Management

Last Updated on : 2023-05-25 06:23:50

A device group includes devices of the same type and gathers a series of devices. Wi-Fi and Zigbee devices can be grouped in most cases. Tuya provides the capabilities to implement device group management. For example, create, rename, manage, or dismiss a group, and manage multiple devices in the same group.

Feature description

The ThingSmartGroup class requires the group ID specified by groupId to implement initialization. An incorrect group ID might cause failed initialization. In this case, the instance returns nil.

    } failure:^(NSError *error) {
        NSLog(@"send add device msg failure");
    }];
}

Swift:

func addDevice() {
    // The value of nodeId can be obtained from ThingSmartDeviceModel::nodeId.

    smartGroup?.addZigbeeDevice(withNodeList: ["nodeId1", "nodeId2"], success: {
        print("send add device msg success")

Parameters

Parameter	Description
nodeList	The list of the target node IDs.
success	The success callback.
failure	The failure callback.

Example

Objective-C:

- (void)removeDevice {
  // Call ThingSmartGroup::groupModel.deviceList to get a list of devices in the group.
  // The value of nodeId can be obtained from ThingSmartDeviceModel::nodeId.
  [self.smartGroup removeZigbeeDeviceWithNodeList:@[@"nodeId1", @"nodeId2"] success:^() {
        NSLog(@"send remove device msg success");
        // Listen for -group:removeResponseCode: to get the actual operation result.
        // After receiving the callback, call -updateGroupRelations:success:failure: at the right time to update the relationship.
  } failure:^(NSError *error) {
        NSLog(@"send remove device msg failure");
    }];
}

Swift:

func removeDevice() {
    // Call ThingSmartGroup::groupModel.deviceList to get a list of devices in the group.
    // The value of nodeId can be obtained from ThingSmartDeviceModel::nodeId.
    
    smartGroup?.addZigbeeDevice(withNodeList: ["nodeId1", "nodeId2"], success: {
        print("send remove device msg success")
        // Listen for group(_, removeResponseCode) to get the actual operation result.
    // After receiving the callback, call updateGroupRelations(_, success, failure) at the right time to update the relationship.
    }) { (error) in
        print("send remove device msg failure")
    }
}

Invoke callback

Returns the result after Zigbee devices are added to or removed from a group through a gateway. When the responseCode in the callback is 0, the operation is successful. Other values indicate a failure. The following table lists the detailed definitions:

responseCode	Description
0	A device was added or removed successfully.
1	The number of groups exceeded the upper limit.
2	A timeout error occurred while processing sub-devices.
3	The specified value was out of range.
4	An error occurred while writing to files.
5	Other errors occurred while processing your request.

The responseCode in the callback is an array of response results, which is consistent with the order of the devices passed in when adding or removing. Example:

Add or remove a device:
- The request parameters: nodeList=[a, b, c]
- The response parameters: responseCode=[0, 1, 0]
Operation result:
- Device a was added or removed successfully.
- Device b was added or removed successfully.
- Device c was added or removed successfully.

Objective-C:

#pragma mark - ThingSmartGroupDelegate

- (void)group:(ThingSmartGroup *)group addResponseCode:(NSArray <NSNumber *>*)responseCode {
    // Returns the result after Zigbee devices are added to a group through a gateway.
}

- (void)group:(ThingSmartGroup *)group removeResponseCode:(NSArray <NSNumber *>*)responseCode {
    // Returns the result after Zigbee devices are removed from a group through a gateway.
}

Swift:

// MARK: ThingSmartGroupDelegate
func group(_ group: ThingSmartGroup?, addResponseCode responseCode: [NSNumber]?) {
    // Returns the result after Zigbee devices are added to a group through a gateway.
}

func group(_ group: ThingSmartGroup?, removeResponseCode responseCode: [NSNumber]?) {
    // Returns the result after Zigbee devices are removed from a group through a gateway.
}

Update and save a group relationship

After devices are added or removed and the response callback is received, depending on the result of the response callback, this API method can be called at an appropriate time to update and save the group device relationship.

Example

There are devices [a, b, and c] in the original group:

Users operate on the UI:
1. Add [e, f]
2. Remove [a, b]
3. Save the group
Procedure to develop an app:
1. Call the API method to add devices to and remove devices from the group.
2. A callback for adding devices is received.
  - responseCode [0, 1] indicates that device e was added successfully and the adding of device f failed.
  - responseCode [1, 0] indicates that the removal of device a failed and device b was removed successfully.
3. Finally, the device list in this group is [a, c, e]. Call the API method of updating and saving the group relationship, and pass devList = [a, c, e].
  
  The API method of updating and saving the group relationship passes devId, rather than nodeId.

API description

- (void)updateGroupRelations:(NSArray <NSString *>*)devList
                     success:(nullable ThingSuccessHandler)success
                     failure:(nullable ThingFailureError)failure;

        NSLog(@"update group relations success");
    } failure:^(NSError *error) {
        NSLog(@"update group relations failure: %@", error);
    }];
}

Swift:

func updateGroupRelations() {
    smartGroup?.updateRelations(["deviceId 2", "deviceId3", ....], success: {
        print("update group relations success")
