I want to combine the different outputs from OPCUA client into 1 JSON object, to be published to MQTT.
This is how the flow looks like:
And the output from the client looks like this:
So, my plan was to filter out the different messages by the topic, and combine the payload into 1 JSON object. The topic is the same as the opcua-string.
Any ideas for how this can be done? Hopefully within one function node.
Thanks in advance

Any easy way to remove this part of the string/name?
Function node before the join...
msg.topic = msg.topic.replace('ns=4;s=|var|HetlelidAuto.Application.0PCUA.','')
