name : create-asset-model.rst **To create an asset model** The following ``create-asset-model`` example creates an asset model that defines a wind turbine with the following properties: - Serial number - The serial number of a wind turbine - Generated power - The generated power data stream from a wind turbine - Temperature C - The temperature data stream from a wind turbine in Celsius - Temperature F - The mapped temperature data points from Celsius to Fahrenheit :: aws iotsitewise create-asset-model \ --cli-input-json file://create-wind-turbine-model.json Contents of ``create-wind-turbine-model.json``:: { "assetModelName": "Wind Turbine Model", "assetModelDescription": "Represents a wind turbine", "assetModelProperties": [ { "name": "Serial Number", "dataType": "STRING", "type": { "attribute": {} } }, { "name": "Generated Power", "dataType": "DOUBLE", "unit": "kW", "type": { "measurement": {} } }, { "name": "Temperature C", "dataType": "DOUBLE", "unit": "Celsius", "type": { "measurement": {} } }, { "name": "Temperature F", "dataType": "DOUBLE", "unit": "Fahrenheit", "type": { "transform": { "expression": "temp_c * 9 / 5 + 32", "variables": [ { "name": "temp_c", "value": { "propertyId": "Temperature C" } } ] } } }, { "name": "Total Generated Power", "dataType": "DOUBLE", "unit": "kW", "type": { "metric": { "expression": "sum(power)", "variables": [ { "name": "power", "value": { "propertyId": "Generated Power" } } ], "window": { "tumbling": { "interval": "1h" } } } } } ] } Output:: { "assetModelId": "a1b2c3d4-5678-90ab-cdef-11111EXAMPLE", "assetModelArn": "arn:aws:iotsitewise:us-west-2:123456789012:asset-model/a1b2c3d4-5678-90ab-cdef-11111EXAMPLE", "assetModelStatus": { "state": "CREATING" } } For more information, see `Defining asset models <https://docs.aws.amazon.com/iot-sitewise/latest/userguide/define-models.html>`__ in the *AWS IoT SiteWise User Guide*.
