Ok, source will be Mqtt Tag which decoded in certain format like Protobuf .. I have code to decode the protobuf to normal JSON Document .
Question : if going to use derived tag where going to build this decoding process .
Normal i used TagChange script to do this onChange and write to new tags . But to use this direct on Mqtt Tag , this will be hard
You can use the runScript() expression function pointing at a function in the global scripting project's libraries.
