Connect external applications to the EMQX broker
This guide explains how to connect external applications to your Amazon IoT SiteWise Edge gateway through an EMQX broker on your deployed MQTT-enabled, V3 gateway. External applications might include custom monitoring tools, third-party visualization software, or legacy systems that need to interact with your industrial data at the edge.
We'll cover the configuration steps for both Linux and Microsoft Windows environments, including EMQX deployment configuration, TLS setup for secure connections, and authorization rules to control access to specific topics.
Note
EMQX is not a vendor or supplier for Amazon IoT SiteWise Edge.
Important
For securing connections to your gateway, we strongly recommend using certificate-based authentication through the Amazon IoT Greengrass client device authentication feature. This method provides robust security through mutual TLS (mTLS) authentication. For more information, see Connect client devices to core devices in the Amazon IoT Greengrass Version 2 Developer Guide.
If you are not able to use certificate based authentication, follow this guide to setup authentication using usernames and passwords.
