Concise and to the point... in five minutes. Kudos!
Wish I had found this several hours of video back.

Awesine tutorial, thanks!

[@willianfreitas1604]

Very good! Your video is excellent

[@vividus101]

Very cool! Keen to get this up and running on my NAS and integrate it into my home weather system. Is this data flow correct: home-weather-station pushes data to mqtt --> Node red subscribes to mqtt --> node red pushes data to database

[@LearnRobotics]

Should be good!

[@automationupdates8979]

super content i have more doubts about mosquitto settings in command promt

[@DesignitBuilditRepairit]

Thanks for an awesome video 👍

[@yacineelhafidy5710]

the best thaaaaaank you love u

[@solarinaction2791]

Could you make a video for the simple data logger where receive data from MODBUS RTU RS-485 and Pub/Sub over MQTT with node red running in ESP 32 / RPi devices.

[@ivaylomanolov1455]

Good job!

[@LearnRobotics]

Thank you! Cheers!

[@nicolasgaete875]

Hi, can you help me? I have mosquito up and running, I can publish and subscribe via the terminal, but when I try localhost:1883 port on moderes it stucks at connecting and nothing happens, what could be the problem?

[@casualrider9435]

Thanks for the video. It seem to me that these work only within "things" connected to the same wifi. How can I set it up to be able to trigger the light from a browser connected to the internet anywhere in the world?

[@LearnRobotics]

Yeah you can find a host like dweet.io where you can pub/sub to things without needing MQTT. I'm sure there are other options out there where you're working across the WWW not your local network.

[@BillBrutzman]

Helpful but _ what about receiving messages from multiple publilshers _ like _ a broker?

[@zachreyhelmberger894]

OK i am already confused. You have Node-RED running in a terminal AND in the Node-Red web browser window? Is there a raspberry pi running mosquitto as a broker somewhere? Is this all on one computer?

[@Geeksmithing]

The IP address she is using is localhost, so that would suggest that Node-Red is not on a different computer but all on her Mac ( as indicated by the UI and Apple Terminal)

[@jasonamosco318]

Can I use this principle for communication of two raspberry pi. One raspberry will control the pin output of another raspberry pi?

[@LearnRobotics]

Yes

[@boalia77]

Super!

[@LearnRobotics]

Thank you! Cheers!

[@serhatkaradag8786]

I cant understand , why I need Mosquitto?
Why can't I connect the esp8266 with the Node-Red on the Computer ?
