Adding data points¶

MindConnect MQTT allows you to create the data model from your own agent using the JSON template. Once your data model is completed, the authenticated agent can simply send the model to Insights Hub using a pre-defined MQTT topic. Instantiating the data model using pre-defined topic results in automatically creating assets, aspects and mapping the variables to the data points. For more information, refer to Creating a data model from MQTT agent.

In addition, you can manually add data points and map them to variables.

Prerequisites¶

• You have onboarded a MQTT agent.

Procedure¶

To add a data point to a data source, for example, "RotationSpeed", follow these steps:

1. Click on your MQTT agent asset in the "Assets" tab.
2. Click on the plugin icon "MindConnect MQTT" to open the MindConnect MQTT plugin.
3. Click "Add new datapoint" and enter the data point name.
4. Search for the asset you want to map the data point to and click on the variable.
5. Click "Add mapping" to save the new data point and the mapping.

Result¶

The new data point is created and mapped.
