Connect to a broker 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 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

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 your script. #1 will contain the received payload #2 will contain the received topic name The options are not required but can be filled if needed There is only 1 option at present 1. Buffer mode (boolean) Default (false) - payload is returned as text If true, payload returned as single column list of values in the range of 0 to 255..

Buffer mode (boolean). Default (false) - the payload is published as text If set to true then payload is expected to be a single column list of values in the 0 to 255 range and is published to the broker as a buffer of bytes. Note: If the payload is a list and you don't set the buffer mode option, it will be automatically be converted into JSON and sent as text.
