I am contemplating using Ignition as a broker to publish data to subscribers like ESP32 or mqttfx. I am curious to know if this is technically feasible?

I understand that I can have another Ignition-loaded transmitter subscribe to an Ignition distributor. I also know that I can use mqttfx as a client to subscribe and publish.

I am looking forward to receiving feedback and suggestions on this matter. Thank you!

The MQTT modules for Ignition are designed to publish using Sparkplug. See this doc for an example setup: [Getting Started: Two Ignition Architecture - MQTT Modules for Ignition 8.x - Confluence](https://docs.chariot.io/display/CLD80/Getting+Started%3A+Two+Ignition+Architecture)

Both modules are also capable of scripted publishes. That info is here: [MQTT Publishing via MQTT Transmission - MQTT Modules for Ignition 8.x - Confluence](https://docs.chariot.io/display/CLD80/MQTT+Publishing+via+MQTT+Transmission)
