 Enable MQTT:Enables MQTT support.
 Broker:DNS or IP address of the MQTT broker.
 TLS:Turns on TLS encryption.
 Mode TCP port:The TCP/IP port number of the broker.
 Username:The MQTT username.
 password:The password for the username.
 Client ID:The MQTT client ID.
 
 [[Datei:Wichtig_zeichen.png]] The client IDs of a user must be different! If two clients of a user have the same name, the connection of one client is normally terminated.
 
 Quality of Service (QoS):Sets the QoS value (0 or 1) of the MQTT publishes.
 Keep-alive ping interval:This defines the time interval in which the client sends an MQTT ping.
 Topic prefix:Defines the beginning of the topic with which all messages are sent. The strings '''[mac]''' and '''[host]''' symbolize the MAC address or the hostname of the device. Permit CLI commands: Enables the execution of console commands.
 Publish device data summary interval:Time interval in which messages with the global status of the device are sent.
 [[Datei:MQTT_Logs-Status.png]]
 MQTT Logs:Outputs individual log messages about the connection setup.
 MQTT Broker Status:Time information about connection duration, the last publish and the last keep-alive.

 <br />This is a switching of the second port to the state on. The source of the switching command is CGI ("http"). The index is always numeric, "port" can also be alphanumeric for devices with multiple banks, e.g. "A2". At the end follows a timestamp ("ts"), which indicates the number of seconds the device is on, or unixtime if the device has synchronized with an NTP server.

 <br />The topic prefix for the messages can be set in the MQTT configuration. A default would be e.g. "de/gudesystems/epc/[mac]". Here "[mac]" is a placeholder for the MAC address of the device, another possible placeholder is "[host]", which contains the host name. An example topic for a switching message of the second port would then be:
