Using Ignition 8.1.17 and CL modules in according versions (4.0.11), Transmission will not publish any tag after the first folder inside the Tag Path folder if you left blank the Edge Node ID field in the transmitter definition.
Is it by design or… ?
Thank you four your direction.
This has to do with how the Sparkplug IDs get picked up either from the Transmitter configuration or from the tag tree folders itself. Have a look at this doc which describes the relationships: MQTT Transmission Transmitters and Tag Trees - MQTT Modules for Ignition 8.x - Confluence
That makes sens. It’s the first time I do not use the SpB transmitter definition, so this surprised me.
