Publishing property value updates to Amazon DynamoDB

This tutorial introduces a convenient way to store your data by using Amazon DynamoDB, making it easier to access historical asset data without repeatedly querying the AWS IoT SiteWise API. After you complete this tutorial, you can create custom software that consumes your asset data, such as a live map of wind speed and direction over an entire wind farm. If you want to monitor and visualize your data without implementing a custom software solution, see Monitoring data with AWS IoT SiteWise Monitor.

In this tutorial, you build on the AWS IoT SiteWise demo that provides a sample set of data for a wind farm. You configure property value updates from the wind farm demo to send data, through AWS IoT Core rules, to a DynamoDB table that you create. When you enable property value updates, AWS IoT SiteWise sends your data to AWS IoT Core in MQTT messages. Then, define AWS IoT Core rules that perform actions, such as the DynamoDB action, depending on the contents of those messages. For more information, see Interacting with other AWS services.

Topics

• Prerequisites
• Step 1: Configure AWS IoT SiteWise to publish property value updates
• Step 2: Create a rule in AWS IoT Core
• Step 3: Create a DynamoDB table
• Step 4: Configure the DynamoDB rule action
• Step 5: Explore data in DynamoDB
• Step 6: Clean up resources after the tutorial

Prerequisites

To complete this tutorial, you need the following:

• An AWS account. If you don't have one, see Setting up an AWS account.

• A development computer running Windows, macOS, Linux, or Unix to access the AWS Management Console. For more information, see Getting Started with the AWS Management Console.

• An IAM user with administrator permissions.

• A running AWS IoT SiteWise wind farm demo. When you set up the demo, it defines models and assets in AWS IoT SiteWise and streams data to them to represent a wind farm. For more information, see Using the AWS IoT SiteWise demo.
