Ignition to mqtt broker without using sparkplug


I have mosquitto broker on a pi and cirruslink mqtt engine module installed on Ignition. I can publish simple topic/message to the broker using system.cirruslink.engine.publish(). I’d also like to subscribe to a topic and I don’t know how to do it without sparkplug.

Is there a simple way/example on to subscribe to a topic or it must be sparkplug compliance? Do I have to use a different module?


Check out the MQTT Engine configuration documentation.


Look for the section Custom Namespace Example

Got it, thank you.
