Hi Joachim,

I’ve considered the MUC room but there is no authorization mechanism that we can use to grant and revoke access to listeners and publishers. This XEP (https://xmpp.org/extensions/inbox/remote-auth.html) proposal looks like it could be useful but it currently not available on servers.

The ‘dealer’ alternative tries to go around that as it sends a ‘canSubscribe’ (currently not in the provisioning spec) to the owner of the ‘dealer’.

Thanks,

Eelco

I do agree we haven't pursued the pubsub for IoT yet I am doing it very simple using MUC rooms today sending xep 323 message events with type="groupchat" to a MUC room meaning that the MQTT topic is the MUC room name/topic and there is one moderator who is "publishing" and anyone joining the room either white listed or not blacklisted can start listening and silently agreeing not to sending by it self.
