MQTT in Node RED: Building a Dashboard and Logging Data

In this video, you will learn how to use Node-RED to build a dashboard and log data. We will start by installing Node-RED and then move on to building a simple “Hello World” example. Next, we will show you how to get data from an ESP32 using MQTT protocol and display it in Node-RED. Finally, we will demonstrate how to log the data in a CSV file. By the end of this video, you will have a solid understanding of how to use Node-RED to build dashboards and log data.

Hiw did you set up the MQTT broker? You haven't said. Is there a link that explains this?

[@djameltalbi2190]

Perfect

[@chamodajayamini6454]

Sir can I run two stepper motors simultaneously and obatin data through nodered?

[@latata1215]

why on my node-red website Cannot GET /ui/

[@malekachour6294]

what is the funcyion between mqtt and neopixel!!

[@HighVoltages]

In this video, neopixel is connected to the ESP32 and ESP32 is connected to the Node-red using MQTT protocol and (MQTT+node red) is allowing us to control the neopixel led.

[@DavidBarnwell876tkdja]

How do you set up an MQTT broker on windows?

[@HighVoltages]

We did not set up the MQTT broker on Windows but we used the hivemq MQTT broker. From windows , using node-red we are just subscribing and publishing data. Please check previous videos, in which we have used hivemq MQTT broker.

[@DavidBarnwell876tkdja]

OK, I figured it out thanks. But in your code you give a client ID. Is that an ID you created or was it autogenerated? If it was autogenerated, where did you find it?@@HighVoltages

[@HighVoltages]

You can write anything in the client id but each device should have a unique client id.

@@DavidBarnwell876tkdja how you did it please ??
