Transform - AWS IoT SiteWise

Transform

Contains an asset transform property. A transform is a one-to-one mapping of a property's data points from one form to another. For example, you can use a transform to convert a Celsius data stream to Fahrenheit by applying the transformation expression to each data point of the Celsius stream. A transform can only have a data type of DOUBLE and consume properties with data types of INTEGER or DOUBLE.
