Hi everyone.  
I'm currently making some tests publishing data from Ignition via MQTT, but when I view the message on the MQTT Explorer the topic has changed, and added the sparkplug version on the namespace.  
Do you know if there is a way to avoid that?

Try publishing with `system.cirruslink.engine.publish`: [MQTT Publishing via MQTT Engine - MQTT Modules for Ignition 8.x - Confluence](https://docs.chariot.io/display/CLD80/MQTT+Publishing+via+MQTT+Engine)

Otherwise, no, if you use SparkPlug you are confined to the SparkPlug namespace/topic structure.

Thanks Kevin, I have a concern about system.cirruslink.engine.publish(). It could be used to publish to a RabbitMQ Broker or it is only designed to operate with Chariot?

It should work with any MQTT broker, and is actually the only way to publish when you _aren't_ using a SparkPlug namespace.
