Hi everyone!

As co-founder and CTO of the United Manufacturing Hub (UMH), I wanted to share with you a valuable resource for getting started with Node-RED in Industrial IoT. We understand that it can be challenging to connect your valuable PLCs or SCADA systems immediately (compliance, security, etc.), which is why we have added simulators to our standard OSS blueprint for Industrial IoT, so that you can start playing around with Node-RED immediately.

These simulators help new users get started on their journey with Node-RED, and we have also created a couple of tutorials to assist you along the way. We invite you to try out Node-RED with simulated PackML, OPC-UA, or MQTT data and create your dashboards with it.

Here are some of our tutorials to get you started:

- Creating a Node-RED Flow with Simulated OPC-UA Data: [How to Create a Node-RED Flow with Simulated OPC-UA Data](https://learn.umh.app/course/creating-a-node-red-flow-with-simulated-opc-ua-data/)
- Creating a Node-RED Flow with PackML: [How to create a Node-RED flow with simulated PackML data](https://learn.umh.app/course/creating-a-node-red-flow-with-packml/)
- Creating a Node-RED flow with simulated MQTT data: [3. Data Acquisition and Manipulation | United Manufacturing Hub](https://umh.docs.umh.app/docs/getstarted/dataacquisitionmanipulation/)

Regards,  
Jeremy

I know nothing about PackML & OPC-UA but is there a specific reason that you used a JSON node after the MQTT node rather than setting the MQTT node to `auto-detect` or `a parsed JSON object`?

Good point actually, thank you!
