  2. Rui I have to apologise. Initially I was about to drop watching this video because I was not sure I would be able to understand your accent. but after watching further the pace and level of your introduction was perfect. I hate having to wait for people to get to the point.

  3. I would like to know how to protect with login and password the interface 1880 / ui dashboard in nodered I cannot find this information anywhere! I have the nodered installed in a VPS anybody enters and can control my automation how to solve it?

  4. MQTT does not actually stand for MQ Telemetry Transport, that was its former definition but the primary focus of the protocol has changed from proprietary embedded systems to open Internet of Things (IoT) use cases. MQTT is no longer considered an acronym. MQTT is simply the name of the protocol.

  5. It's always a pleasure to watch your tutorials Rui! It only takes one time to understand and that is pretty awesome, thanks for this nice way of explaining!

  6. Trying to dive into IoT home automation head-first has been a challenge. I was having a real hard time trying to wrap my head around how MQTT works, and this video did a great job at breaking it down. Thanks so much for putting this quick presentation together.

  7. try this Web SCADA platform to create free MQTT connection to public MQTT broker: https://www.youtube.com/watch?v=u8Vm6SWnbj0

  8. Can someone please explain in a few words the advantages and disadvantages of MQTT vs simply serving JSON data from your device based on the given HTTP request?

  9. I'm new to all this and greatly appreciate your tutorial, but I'm also suspicious of this technology.
    Are there a lot of MQTT Brokers, are they fee based and are there MQTT Brokers that should be avoided?
    Once a device like a motion sensor and/or camera is setup using an ESP8266, can MQTT Brokers access the router and/or modem to intercept data transferred from other devices for the purpose of data mining?

  10. How the devices are connected with the broker? Are they opening a websocket connection which lives for the life time? What is the communication channel underneath MQTT?

  11. Hello Rui, thank you very much for this instructional. I am currently working in a document about application layer protocols in IoT and I'm struggling with some topics (I'm a Industrial Engineerig). Where can I grab some resources about this topic. Saludos desde Guatemala, muchas gracias
