Connect to MQTT!

See how with an example

Example package: @plus4nodered/node-red-contrib-opcua-client

You have many ways to connect to MQTT easily with the @plus4nodered packages.

The first method you can use is sending the items you want to use for a service with MQTT on a topic. These items get their parameters and correct UMS in an P4NR OPC UA Inject Node and from there right into the service. After that, you can work with the result. Extract or transform data and send it on another topic. Node-RED lets you easily do this!

Another way is to only send results to MQTT for a custom MQTT interface. Node-REDs MQTT Nodes and P4NR OPC UA Nodes make it super easy to dynamically monitor, extract and transform data and send this data onto dynamic MQTT topics!
