# IotSiteWiseAction


Sends information about the detector model instance and the event that triggered the action to a specified asset property in AWS IoT SiteWise.

You must use expressions for all parameters in `IotSiteWiseAction`. The expressions accept literals, operators, functions, references, and substitutions templates.

**Examples**
+ For literal values, the expressions must contain single quotes. For example, the value for the `propertyAlias` parameter can be `'/company/windfarm/3/turbine/7/temperature'`.
+ For references, you must specify either variables or input values. For example, the value for the `assetId` parameter can be `$input.TurbineInput.assetId1`.
+ For a substitution template, you must use `${}`, and the template must be in single quotes. A substitution template can also contain a combination of literals, operators, functions, references, and substitution templates.

  In the following example, the value for the `propertyAlias` parameter uses a substitution template. 

   `'company/windfarm/${$input.TemperatureInput.sensorData.windfarmID}/turbine/ ${$input.TemperatureInput.sensorData.turbineID}/temperature'` 

You must specify either `propertyAlias` or both `assetId` and `propertyId` to identify the target asset property in AWS IoT SiteWise.
