external MQTT communication. You can check the setup by opening MQTT-broker node
and clicking on the pen next to the server:
a. Internal MQTT Broker:
i. Server: mqtt-internal-IPC
ii. Port: 1883
b. External MQTT Broker:

MQTT brokers and the specified Topic once a second. Receiving flows are configured to
listen to specified Topics and once a new message is published, it will send the message to
the debug node. By default, debug nodes are switched off, so nothing will be seen in the
debug window. Click on the debug node activation button to turn it on and you will either
see a timestamp or a HELLO message being received once a second.
