Hey @donpancoe. I did get IA Ignition and the UMH talking to one another in a lab environment. I used the Cirrus Link MQTT modules to facilitate the flow of tag data into the UMH and let the UMH historian do its thing. The UMH DB could be exposed directly to the Ignition gateway by turning on ingress (i think, haven't tried this before) but architecture-wise I think it's best to treat IA Ignition like an edge node to take full advantage of what the UMH can do.
