MQTT: add support for username and password

rafek00 commented 5 years ago

Hello, would it be possible to expand MQTT version, with user support and password ?

FrankUlbrich commented 5 years ago

Yes , it is possible. I did it yesterday. I can paste the code snipplet if you like .

`settings.h

...

/****** MQTT Settings ********************************************************/
const char* mqtt_server = "192.168.4.21";     // MQTT Server (broker) address
const char* mqtt_user = "iobroker";           // MQTT Server (broker) userid
const char* mqtt_pass = "iobroker";           // MQTT Server (broker) password
...

solar-wifi .. .ino
...
void connect_to_MQTT() {
  Serial.print("---> Connecting to MQTT, ");
  client.setServer(mqtt_server, 1883);

  while (!client.connected()) {
    Serial.println("reconnecting MQTT...");
    reconnect(); 
  }
  Serial.println("MQTT connected ok.");
} //end connect_to_MQTT

void reconnect() {
  // Loop until we're reconnected
  while (!client.connected()) {
    Serial.print("Attempting MQTT connection with ");
    // Create a random client ID
    String clientId = "ESP8266Client-";
    clientId += String(random(0xffff), HEX);
    Serial.print(clientId.c_str());
    // Attempt to connect
    if (client.connect(clientId.c_str(), mqtt_user, mqtt_pass )) {
      Serial.println("connected");
       // Once connected, publish an announcement...
      client.publish("solarweatherstation/debug", "SolarWeatherstation: client started...");
      delay(50);
    } else {
      Serial.print(" ...failed, rc=");
      Serial.print(client.state());
      Serial.println(" try again in 5 seconds");
      // Wait 5 seconds before retrying
      delay(5000);
    }
  }
} //end void reconnect*/

Thank you Frank.

3KUdelta - Tkanks a lot for sharing the code. I added a DHT22 Sensor and would like to transfer data to an INFLUX DB. This will be my next step. I am waiting for my UV sensor, which I would like to integrate. Maybe I can share this with you. Greeting from Germany

Hi Frank. The easiest way to do this if you just fork my work and put your solution there. I am happy to do a comment on the main page to describe your add-ons.

Hi 3KUdelta, thank you very much for your offer to fork your briliant solution. In the moment we are going to vacation. When I am back I have to learn how to do it and whcih tool I should use to access gitub for forking. I guess there is a way to sync the code from my laptop.
