Python MQTT for Data-Driven Engineering

MQTT (Message Queue Telemetry Transport) is a protocol for machine-to-machine communication that is popular in IoT (Internet of Things) networks. The broker manages data transport from clients that publish or subscribe to updates. It was created around 1998 and has increased in popularity with the increase of IoT devices. It is especially good for ad hoc networking of devices that have varying levels of latency and communication bandwidth. MQTT typically runs over TCP/IP for bi-directional and lossless connections.

Dear Sir, Thank you thank you for this series. I have watched the whole playlist. I have a project whereby I have to get rid of the Modbus gateway between the plc and Raspberry Pi. I saw that I can use MQTT or OPC UA. My question is which is better. Can I use it to run plc even without a Raspberry PI since it's not industrial? Thank you so much

I want to create an MQTT client to listen to a host machine but I do not know the "topics" hence I am not able to subscribe to them. Is there any way I can find out what are the available topics from the host? Anyone?
