Dynamic subscription unsubscribe-from-all (and docs)

[Steve-Mcl]

@tymarbut

I'm hoping there's a way to tell an MQTT In node to unsubscribe from all topics it's currently subscribed to

Set...

• msg.action: "unsubscribe"
• msg.topic: true

@tymarbut

That would be very helpful, rather than maintaining my own list of the previously-subscribed topics.

You can send an action of "getSubscriptions" then use the result to unsubscribe.

Demos on forum...

• A full demo including "unsubscribe all" & "get subscriptions": Dynamic MQTT LWT birth, Close & Will Property - #2 by Steve-Mcl

And are there any plans for updating the node info that displays in the info panel at the right? There's no info displayed currently,

There is info...

... however, as always, it could be improved.

Pull Requests are welcome (for both the nodes built in documentation and for the node-red website
