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.
