There must* be only one broker.

All clients (node-red is a client, your device is a client) talk to ONE broker

That is the definition of a broker ( A broker is an intermediary between clients )

This thread might help you get it.




* there can of course be more than one broker but for what you are trying to achieve, there should only be one broker
