Hi, all.

I posted my HiveMQ extension that monitors Sparkplug B topics and “expands” them automatically by converting Sparkplug metrics into individual topics and the metadata into other topics. All are published back with the “retain” flag.

The code is posted at:

Feel free to use it, fork it, whatever.
