Simulating machines for the United Manufacturing Hub
3 minute read
MQTT Simulator
With the version 0.9.6 the United Manufacturing Hub automatically generates messages about a simulated machine, let’s imagine it is a cooking pot. It has the three message types “Temperature”, “Pressure” and “Humidity” with the root topic “ia/raw/development/ioTSensors”, so messages would have the topic of “/ia/raw/development/ioTSensors/Temperature” for example.
This is a feature brought in by the external contributor Amine Amaach. Take a look at his repository for more information about simulating data. It does however require in-depth knowledge about helmcharts and config maps to get into simulating more intricate data.
If you installed the correct version of the United Manufacturing Hub, you should then be able to process that test data with Node-RED by accessing it via
If you don’t want to create a Node-RED flow yourself, you can import the simulated data converter from our Node-RED library instead.
For a detailed explanation for data processing for these simulated data sets, look at our Creating a Node-RED flow with simulated MQTT data article.
Feel free to adjust it to your liking and work with our other message types instead.
PACKML Simulator
With the version 0.9.9 the United Manufacturing Hub automatically generates a simulated PackML machine, which you can control by sending messages to it.
This is a feature we implemented from an image of the Open-Source software of this repository, take a look to learn more about controlling the simulated machine.

Feel free to adjust your flows to your liking and work with our other message types instead.
OPC UA Simulator
The United Manufacturing Hub also comes with an OPC UA simulator, which generates messages about a simulator machine. By default the topics of these messages are ConcentrationN2, ConcentrationNH3 and ConcentrationH2.
This is a feature we brought in from the external contributor Amine Amaach. Take a look at his repository for more information about simulating data.
