<script type="text/x-red" data-help-name="mqtt-broker">
<p>A minimum MQTT broker connection requires only a broker server address to be added to the default configuration.</p>
<p>To secure the connection with SSL/TLS, a TLS Configuration must also be configured and selected.</p>
<p>If the <b>Server</b> option is set to a full url (e.g. ws://example.com:8083/mqtt), then the <b>Port</b> setting will be disabled and ignored. See <a href='https://github.com/mqttjs/MQTT.js' target="_blank">mqttjs</a> for applicable urls.</p>
<p>To secure the connection with SSL/TLS, a TLS Configuration must also be configured and selected. (not applicable to wss://)</p>
<p>If you create a Client ID it must be unique to the broker you are connecting to.</p>
