What do I need before creating the AWS IoT Core rule?
Complete the prerequisite path to prepare the weather station emulator and connect it to AWS IoT Core. The rule relies on that running message source.
Where do I create the rule in AWS IoT Core?
Open AWS IoT Core, select Message routing, then select Rules and Create rule to start configuring it.
What should I name the rule?
Use send_message_to_dynamodb. While you can choose a different valid name, use the suggested name to stay consistent with the Learning Path.
Which MQTT topic should the rule target?
Use the same topic that the weather station emulator uses in the prerequisite Learning Path Create IoT applications with Windows on Arm and AWS IoT Core .
How do I know the rule is writing data to DynamoDB?
After saving the rule and running the emulator, new items should appear in the DynamoDB destination you configured. If nothing appears, confirm the emulator is connected and that the rule’s configuration matches the emulator’s message topic.
