Hi there,
After looking into your query, I can see that one of our users already had an issue similiar to yours, and it seems that the guide provided has helped. I would recommend you also to look into this thread and follow the steps in the guide : Can I get RUTX50 to send GPS data over MQTT?
You basically need to pull data via modbus, and then you can send it to your MWTT server via Data to server feature.
Please advise if you need further assistance.
Regards,
