Hi, 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? Thanks. ---

Check out the MQTT Engine configuration documentation. [https://docs.chariot.io/display/CLD80/ME%3A+Configuration](https://docs.chariot.io/display/CLD80/ME%3A+Configuration) Look for the section **Custom Namespace Example** ---
