Step 5: Creating and configuring a device asset

In this procedure, you generate a device asset that's based on your device asset model. Then, you define property aliases for each measurement property. A property alias is a unique string that identifies an asset property. Later, you can identify a property for data upload by using the aliases instead of the asset ID and property ID. For more information, see Mapping industrial data streams to asset properties.

To create a device asset and define property aliases

  1. Navigate to the Amazon IoT SiteWise console.

  2. In the left navigation pane, choose Assets.

  3. Choose Create asset.

  4. Under Model information, choose your device asset model, SiteWise Tutorial Device Model.

  5. Under Asset information, enter a name for your asset. For example, SiteWise Tutorial Device 1.

  6. Choose Create asset.

  7. For your new device asset, choose Edit.

  8. Under CPU Usage, enter /tutorial/device/SiteWiseTutorialDevice1/cpu as the property alias. You include the Amazon IoT thing's name in the property alias, so that you can ingest data from all of your devices using a single Amazon IoT rule.

  9. Under Memory Usage, enter /tutorial/device/SiteWiseTutorialDevice1/memory as the property alias.

  10. Choose Save.

If you created multiple Amazon IoT things earlier, repeat steps 3 through 10 for each device, and increment the number in the asset name and property aliases accordingly. For example, the second device asset's name should be SiteWise Tutorial Device 2, and its property aliases should be /tutorial/device/SiteWiseTutorialDevice2/cpu, and /tutorial/device/SiteWiseTutorialDevice2/memory.
