AssetPropertyValue

A structure that contains value information. For more information, see AssetPropertyValue in the AWS IoT SiteWise API Reference.

You must use expressions for all parameters in AssetPropertyValue. The expressions accept literals, operators, functions, references, and substitution templates.

Examples

For literal values, the expressions must contain single quotes. For example, the value for the quality parameter can be 'GOOD'.
For references, you must specify either variables or input values. For example, the value for the quality parameter can be $input.TemperatureInput.sensorData.quality.

For more information, see Expressions in the AWS IoT Events Developer Guide.
