In this video tutorial we will look at using and configuring the MQTT publish and subscribe nodes.
The flow will demo publishing messages and subscribing to topics and receiving messages.
We look at the main settings like birth and will messages,SSL security and user name and password.
We also look at creating new broker connections using different clients using different client ids.
Understand that MQTT publish and subscribe nodes share connection information and why you should be aware of this when editing MQTT nodes.
Finally we create a very simple open/closed sensor that you can use for testing.
