The options are not required but can be filled if needed

1. username (some brokers need this)
2. password (some brokers need this)
3. keepalive (default time is 60 seconds but some brokers need a shorter time)
4. connection callback (ringed set of scripts to be run when connection is made or remade)

Note: The connection callback doesn''t have to be the 4th option - it just has to be the last (or only) option.

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

Make sure you have already run an MQTT connect block before using this one

You should add a script to be run inside he grey ring.

It will be run each time a message is received

If you click on the arrow on the grey ring twice, you can use #1 and #2 inside yoiru script.

#1 will contain the received message

#2 will contain the received topic name</comment><header></header><code></code><translations></translations><inputs><input type="%s">broker.emqx.io<options>broker.emqx.io
