 ; Power L1 : 126.43
 ; Power L2 : 120.24
 ; Power L3 : 149.72
 ; Power N : 152.47
Connecting...
{"success":false,"message":"Username or password empty"}
Disconnecting......

 

Below is my sketch for HTTP Request.

// this method makes a HTTP connection to the server:
void sendData() {
  // if there's a successful connection:
  if (client.connect(server, 8081)) {
    Serial.println("Connecting...");
    // send the HTTP GET request:
       client.print("GET /input/post.json?");
    if (node > 0) {
      client.println("node=");
      client.println(node);
    }
    client.print("&json={");
    client.print("power-L1:");
    client.print(Irms1*volt);
    client.print(",power-L2:");
    client.print(Irms2*volt);
    client.print(",power-L3:");
    client.print(Irms3*volt);
    client.print(",power-N:");
    client.print(Irms4*volt);
    client.print("}&apikey=");
    client.print(apikey);
    client.println(" HTTP/1.1");
    client.println("Host:192.168.0.4");
    client.println("User-Agent: Arduino-ethernet");
    client.println("Connection: close");
    client.println();

    // note the time that the connection was made:
    lastConnectionTime = millis();
  }
  else {
    // if you couldn't make a connection:
    Serial.println("Connection failed");
    Serial.println("Disconnecting...");
    client.stop();
  }
}
