Scene Recommendation

Scene recommendation is designed to improve connections between users and smart devices through scene services and enhance smart scene capabilities for the devices.

This topic describes API methods for scene recommendation to implement a range of features. For example, get a list of recommended scenes, get a list of recommended scenes for a specific device, get details of a recommended scene, and add or remove a recommended scene. For more information about scene recommendation, see Scene Recommendation Management.

Get the latest matching scenes to recommend

API description

Returns a list of the latest scenes that match certain conditions before you call getRecommendAll that returns a list of recommended scenes.

fun requireRecommendMatch(relationId: Long, callback: IResultCallback<Boolean>?)

Parameters

Parameter	Description
relationId	The home ID.
callback	The callback.

Example

• For App SDK v3.34.5 and later:

  	TuyaHomeSdk.getSceneServiceInstance().recommendService().requireRecommendMatch(
  			relationId,
  			object : IResultCallback<Boolean>() {
  				override fun onSuccess(result: Boolean) {
  
  				}
  				override fun onError(errorCode: String?, errorMessage: String?) {
  
  				}
  			})
  

• For App SDK versions earlier than v3.34.5:

  			public void onSuccess() {
  
  			}
  	});
