get_asset_property_value#

IoTSiteWise.Client.get_asset_property_value(**kwargs)#

Gets an asset property’s current value. For more information, see Querying current values in the 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.
