ADVANCED: The brokers offered in the menu are accessed using default ports and basepaths (if needed). If accessing other brokers, the complete urls should be formed like this: siteURL:port/basepath e.g mqtt.eclipseprojects.io:443/mqtt It is possible to have more than one connection to the same broker, for instance, using two different user/pass accounts simultaneously. To do this, add a connection id at the end of the broker: e.g mqtt.eclipseprojects.io:443/mqtt|1
