describe_asset_property#
- IoTSiteWise.Client.describe_asset_property(**kwargs)#
Retrieves information about an asset property.
Note
When you call this operation for an attribute property, this response includes the default attribute value that you define in the asset model. If you update the default value in the model, this operation’s response includes the new default value.
This operation doesn’t return the value of the asset property. To get the value of an asset property, use GetAssetPropertyValue.
