Hmm…Just to be clear, I am not using the MQTT Group ID and Edge Node ID in the namespace. I am using Ignition’s name space only. (Fields are blank in the configuration of Gateway for MQTT Group/Node IDs)
Oddly the system (Designer) allows me to configure this architecture without constraint, but it was only when I noticed the unusual data quality color changes and the fact the the “heartbeats” were not displaying did I realize that this namespace design had problems. (see figure below)
