Is it technically possible to use Ignition as a broker to publish data to a subscriber, such as ESP32 or mqttfx?

Ignition Modules

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!

MQTT Distributor is a fully compliant MQTT Server and is a module that can be installed into Ignition: MQTT Distributor - MQTT Modules for Ignition 8.x - Confluence

The download is here: https://inductiveautomation.com/downloads/third-party-modules/8.1.39

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

Both modules are also capable of scripted publishes. That info is here: MQTT Publishing via MQTT Transmission - MQTT Modules for Ignition 8.x - Confluence
