How to Get Started with MQTT

i didnt quite get the use of this when we talked abt it during my studies now i need it for private projects thanks for the tutorial!

Without using your hardware, could you provide examples showing the tables maintained by the broker to keep track of topics, similar to Arp or router tables.

Great vid. Thank you

great video, am I correct to say that NodeRED is a routing mechanism to send the data from A to B ? if yes... what is the difference between the broker and the router?

Im confused i think, where is the broker sw running in this instance?? On the groove epic?? Cheers.

Very nice vedio.... Can i have your email.... I have a site inquiry....from Seawage Treatment Plant



We have some actuators (Auma) actuators.... They are installed in wett well area whre the access is quite difficult. If any problem comes, engr or technician has to go down to checkout the actuator problem...

Can we use... MQTT to have all actuator values upto the existing SCADA.... like actuator's

Open Command
Close Command

Emergency Stop....
Etc..



We need al these signals.... to easily accessible place where technicians may troubleshoot easily......

This is very interesting. Can i configure a Linux sever to send my broker MQTT data for CPU alerts and such?

Hi, Please I am trying to connect my IoT homelab kit to the broker and then to have the message displayed on Nord-RED. Can you Help?

This was messy. Don't get it.

hi, can you explain to me a little bit about MQTT as I'm stuck? I want to send a message from my laptop to node MCU or esp8266. I have an MQTT broker installed on my laptop, so I will use that broker or my self-made server/broker.

how do you connect a wireless sensor to node red?

hello , It is possible to create real time chat application using mqtt in node js ??

Really good work - Thanks you

Would you have an ETA on how long a tutorial for Clustering MQTT across two datacenters would be?

How do we work this out with android App devs

I want to build my own iot broker can u help me out on that

For practice with a lab google MIMIC MQTT Lab

Very well explained (y)

Have you ever considered using an IO Link master to deliver sensor outputs to the MQTT broker?

if the groov epic a plc? and if so where do i find info on the plc programming environment?

thak you so much for your explication, it's really amazing but, I have a question please, how can we connect this protocol MQTT with an API?

Awesome video, nice graphics and a great explanation! Cheers guv

If you're video is on MQTT on the Groov Epic, then the title should reflect that. And WHY does everyone making an MQTT video think we need a ten minute lesson on what it's about (Zz-zzzzz-zzzzzzzzzzzzz....) and zero coverage of how to get it installed and running correctly???

Nice video and informative! I have a question, when you sent workshop/switch to True, how did the client know that "True" means to turn on the LED?
