MQTT is a protocol that sends messages to a broker, with different types of information, organized in different topics.
It works basically like WhatsApp:
You have different groups (TOPICS)
To which you send different MESSAGES
People (or devices) can SUBSCRIBE to a group
to get the messages you PUBLISH.
The topics can have many subtopics inside:
POWAR / CITY / TEMPERATURE
POWAR / CITY / WIND
POWAR / CITY / SUN
POWAR / HOUSE / LIGHT
POWAR / HOUSE / TEMPERATURE
POWAR / LED
An easy way of doing it is with the WiFIManager Library, which turns your ESP8266 into a WiFi Network that you can see at home, and when you connect to it, you can now choose your WiFi and enter your WiFi password to connect.
Now we need to download the "WiFiManager" library created by tzapu.
in Arduino IDE:
TOOLS > MANAGE LIBRARIES >
#include <ESP8266WiFi.h>
#include <DNSServer.h>
#include <ESP8266WebServer.h>
#include <>
void setup()
{
Serial.begin(115200);
// Create an instance of the class WiFiManager
WiFiManager wifiManager;
// Un-comment to reset the configuration
//wifiManager.resetSettings();
// We create a captive portal
wifiManager.autoConnect("***POWAR***", "12345678");
Serial.println("POWARfull Connection");
}
void loop() {}
