This is a node module for node-red that is identical to the default MQTT node. The difference with the MQTT node is that this dynamic node supports topics/channels passed through msg.topic.
Simply install using the palette in node-red.
I have used node-red-contrib-mqtt-env as a raw base for this node. Thank you.
This is a fork of node-red-contrib-mqtt-dynamictopic
=> correct multi subscriptions usage and unsubscriptions.
