First of all thank you all for the wonderful work.
Does anyone think it might be useful to integrate the sparkplug b specific into HA?
I don’t think it is implemented since the use cases are way too small. But I wish it would be added 
i think you can by adding node red mqtt sparkplug contrib
i’m working on automatic irrigation system, and trying to publish mqtt messages to ignition scada, i’ll share my work as soon as it works properly i hope.
