MQTT is a lightweight binary pubsub protocol suited to embedded devices. This module provides a way for MQTT clients to connect to Prosody and publish or subscribe to local pubsub nodes.
MQTT has the concept of ‘topics’ (similar to XMPP’s pubsub ‘nodes’).
mod_pubsub_mqtt maps pubsub nodes to MQTT topics of the form
HOST/NODE, e.g.pubsub.example.org/mynode.
The current implementation is quite basic, and in particular:
XMPP payloads are always XML, but MQTT does not define a payload format. Therefore mod_pubsub_mqtt will attempt to convert data of certain recognised payload types. Currently supported:
<data xmlns="https://prosody.im/protocol/mqtt"/>)All other XMPP payload types are sent to the client directly as XML. Data published by MQTT clients is currently never translated, and always treated as UTF-8 text.
There is no special configuration for this module. Simply load it on your pubsub host like so:
Component "pubsub.example.org" "pubsub"
modules_enabled = { "pubsub_mqtt" }You may also configure which port(s) mod_pubsub_mqtt listens on using
Prosody’s standard config directives, such as mqtt_ports.
Network settings must be specified in the global
section of the config file, not under any particular pubsub component.
The default port is 1883 (MQTT’s standard port number).
