Deleting assets

You can use the AWS IoT SiteWise console or API to delete an asset.

Before you can delete an asset, you must first disassociate its child assets and disassociate it from its parent asset. For more information, see Associating and disassociating assets. If you use the AWS Command Line Interface (AWS CLI), you can use the ListAssociatedAssets operation to list an asset's children.

When you delete an asset, its status is DELETING until the changes propagate. For more information, see Asset and model states. After the asset is deleted, you can't query that asset. If you do, the API returns an HTTP 404 response.

Important

AWS IoT SiteWise deletes all property data for deleted assets.

Deleting an asset (AWS CLI)

You can use the AWS Command Line Interface (AWS CLI) to delete an asset.

Use the DeleteAsset operation to delete an asset. Specify the following parameter:

• assetId – The ID of the asset. This is the actual ID in UUID format, or the externalId:myExternalId if it has one. For more information, see Referencing objects with external IDs in the AWS IoT SiteWise User Guide.

To delete an asset (AWS CLI)

1. Run the following command to list the asset's hierarchies. Replace asset-id with the ID or the external ID of the asset:

   aws iotsitewise describe-asset --asset-id asset-id

   The operation returns a response that contains the asset's details. The response contains an assetHierarchies list that has the following structure:

   {
     ...
     "assetHierarchies": [
       {
         "id": "String",
         "name": "String"
       }
     ],
     ...
   }

   For more information, see the DescribeAsset operation.

2. For each hierarchy, run the following command to list the asset's children that are associated with that hierarchy. Replace asset-id with the ID or external ID of the asset and hierarchy-id with the ID or external ID of the hierarchy.

   aws iotsitewise list-associated-assets \
     --asset-id asset-id \
     --hierarchy-id hierarchy-id

   For more information, see the ListAssociatedAssets operation.

3. Run the following command to delete each associated asset and then to delete the asset. Replace asset-id with the ID or external ID of the asset.

   aws iotsitewise delete-asset --asset-id asset-id
