How to Run the Sample

1. Open the production and start it. It will start observing the MQTT topic /DeviceStatusInputTopic and it will produce responses to MQTT topic /DeviceStatusOutputTopic. See:

2. Use a MQTT client to send a message and test the production. For this, into your Google Chrome browser access https://chrome.google.com/webstore/detail/mqttbox/kaajoficamnjijhkeomgfljpicifbkaf. It is the Chrome Plugin MQTTBox. Click Add to Chrome and after Add App.

• All other settings are the default values

6. Configure the MQTT topics to send and receive MQTT messages:

• Topic to publish: /DeviceStatusInputTopic
• Topic to subscribe: /DeviceStatusOutputTopic
• Payload:

{
"deviceId":"Air Conditioner Level 1",
"statusDate":"2023-01-07 14:03:00",
"status": 0
}

7. Click the button Subscribe to listen messages on the topic /DeviceStatusOutputTopic. Now the UI changes to wait for messages on this topic.

8. Click the button Publish to send a message to /DeviceStatusInputTopic and see the results produced by IRIS production on /DeviceStatusOutputTopic
