<dd>set to true to retain the message on the broker. Default false.</dd>

<h3>Details</h3>
<code>msg.payload</code> is used as the payload of the published message.
If it contains an Object it will be converted to a JSON string before being sent.
If it contains a binary Buffer the message will be published as-is.</p>
<p>The topic used can be configured in the node or, if left blank, can be set by <code>msg.topic</code>.</p>
<p>Likewise the QoS and retain values can be configured in the node or, if left
blank, set by <code>msg.qos</code> and <code>msg.retain</code> respectively. To clear a previously
retained topic from the broker, send a blank message to that topic with the retain flag set.</p>
<p>This node requires a connection to a MQTT broker to be configured. This is configured by clicking
the pencil icon.</p>
<p>Several MQTT nodes (in or out) can share the same broker connection if required.</p>

<p>Configuration for a connection to an MQTT broker.</p>
<p>This configuration will create a single connection to the broker which can
then be reused by <code>MQTT In</code> and <code>MQTT Out</code> nodes.</p>
<p>The node will generate a random Client ID if one is not set and the
node is configured to use a Clean Session connection. If a Client ID is set,
it must be unique to the broker you are connecting to.</p>
<h4>Birth Message</h4>
<p>This is a message that will be published on the configured topic whenever the
connection is established.</p>
<h4>Close Message</h4>
<p>This is a message that will be published on the configured topic before the
connection is closed normally, either by re-deploying the node, or by shutting down.</p>
<h4>Will Message</h4>
<p>This is a message that will be published by the broker in the event the node
unexpectedly loses its connection.</p>
<h4>WebSockets</h4>
<p>The node can be configured to use a WebSocket connection. To do so, the Server
field should be configured with a full URI for the connection. For example:</p>
<pre>ws://example.com:4000/mqtt</pre>
