Send inputs to test the detector model in AWS IoT Events

To send inputs to test the detector model

1. Open the AWS IoT Core console. In the left navigation pane, under Manage, choose Message routing, then choose Rules.

2. Choose Create rule in the upper right.

3. On the Create a rule page, complete the following steps:

   1. Step 1. Specify rule properties. Complete the following fields:

      • Rule name. Enter a name for your rule, such as MyIoTEventsRule.

        Note

        Do not use spaces.

      • Rule description. This is optional.

      • Choose Next.

   2. Step 2. Configure SQL statement. Complete the following fields:

      • SQL version. Select the appropriate option from the list.

      • SQL statement. Enter SELECT *, topic(2) as motorid FROM 'motors/+/status'.

      Choose Next.

   3. Step 3. Attach rule actions. In the Rule actions section, complete the following:

      • Action 1. Select IoT Events. The following fields appear:

        1. Input name. Select the appropriate option from the list. If your input doesn't appear, choose Refresh.

           To create a new input, choose Create IoT Events input. Complete the following fields:

           • Input name. Enter PressureInput.

           • Description. This is optional.

           • Upload a JSON file. Upload a copy of your JSON file. There is a link to a sample file on this screen, if you don't have a file. The code includes:

             {
               "motorid": "Fulton-A32",
               "sensorData": {
                 "pressure": 23,
                 "temperature": 47
               }
             }
             

           • Choose input attributes. Select the appropriate option(s).

           • Tags. This is optional.

           Choose Create.

           Return to the Create rule screen and refresh the Input name field. Select the input you just created.

        2. Batch mode. This is optional. If the payload is an array of messages, select this option.

        3. Message ID. This is optional, but recommended.

        4. IAM role. Select the appropriate role from the list. If the role isn't listed, choose Create new role.

           Type a Role name and choose Create.

        To add another rule, choose Add rule action

      • Error action. This section is optional. To add an action, choose Add error action and select the appropriate action from the list.

        Complete the fields that appear.

      • Choose Next.

   4. Step 4. Review and create. Review the information on the screen and choose Create.

4. In the left navigation pane, under Test, choose MQTT test client.

5. Choose Publish to a topic. Complete the following fields:

   • Topic name. Enter a name to identify the message, such as motors/Fulton-A32/status.

   • Message payload. Enter the following:

     {
       "messageId": 100,
       "sensorData": {
         "pressure": 39
       }
     }

     Note

     Change the messageId each time you publish a new message.

6. For Publish, keep the topic the same, but change the "pressure" in the payload to a value greater than the threshold value that you specified in the detector model (such as 85).

7. Choose Publish.
