GetAssetPropertyValueHistory

Gets the history of an asset property's values. For more information, see Querying historical values in the AWS IoT SiteWise User Guide.

To identify an asset property, you must specify one of the following:

The assetId and propertyId of an asset property.
A propertyAlias, which is a data stream alias (for example, /company/windfarm/3/turbine/7/temperature). To define an asset property's alias, see UpdateAssetProperty.
