ESP8266 (NodeMcu) Raspberry Pi MQTT | ESP8266 Publish/Subscribe

This is the 3rd video of How to MQTT series. In this video, we will learn how to subscribe and publish MQTT messages using ESP8266 (NodeMcu). We will use the Raspberry pi as Local mosquitto MQTT broker which we created in the last video.

We will read the temperature and humidity values from a DHT11 sensor using Nodemcu and publish it on topic "data", raspberry pi will subscribe to that topic and receive that data. So this can also be considered as "Raspberry pi Esp8266 Wireless communication" or "NodeMcu Raspberry pi IoT".

You already know youre getting the best when the indish accent starts.

[ZersoLP]

Some comments say the music is distracting but I think its fine. Instead you should get a better microphone to hear your voice clearer over the music. Great video!

[kunalbiz]

Your videos are top notch.. keep it up

[chrisw]

You have a very strong accent, to an American, and the background music is just a little too loud. Together it makes listening very hard.

Sir,
How to send one digital input and receive one digital output? Say, we have two esp8266 through adafruit broker. One esp digital input will make another esp digital output high and vice versa. Please help me out.

[someonecooltech]

so esp8266 don't have to connect to WIFI?

[JKFCV]

What is the fastest speed of communication? That is how many values per second can be transmitted?

[mommypotatottv]

is there a tuto of how to link the node mcu or the gateway with cloud

[Joshrp]

Hi, is there a way to publish to MQTT with retained flag active from this MCU?

[baseladams]

What do need to do, if the Raspberry pi and the esp32 arr not on the same wifi? In other words, how subscribe Mqtt Messages over internet? Thank you for the video!

[bradlevan]

I’m using DS18b20 sensor on D2 (only pin that seems to work) & 128X32 i2c OLED to display Current temp on D1&D2. Can you assist with code? I can get each to work independently but not together. Great videos!

[wajdibrahem]

the portal config won't open ! some one help me plz !

[moshebensal]

Very interesting.
It's not clear to me, why we need background music?
This is very disturbing to me, and I'm sure many more people,
Too bad.

i am getting these errors please help me sir

[dsdridi]

hi, ican u help me ?

my esp8266 dont reconnect to mqtt broker ( on node red raspberry pi ) after when the pi reboot .

[hayafatime]

Can we connect our local pi network to firebase to publish data?

[kuldipgami]

Raspberry pi send data to nodemcu via local or globall

[ennaiarindhal]

Bro can read flow sensor Data using esp8266 raspberry pi

[SepahEMahdi]

background music is too laud and pointless we cannot even hear you
