According to this document for communication via MQTT hosting via Azure or AWS is required.
How is it possible to communicate with a self-hosted MQTT server?
I succesfully communicate with my own mqtt server by entering my mqqt server details in the MQTT Modbus Gateway
Hi @mrh1997
It is only designed for Azure or AWS; however, you can try to test if it will work , Use AWS IoT Custom and upload the required certificates and keys
