Hi
first many thanks for the wifimanager, i'am very enthusiastic!
I need your support for send pushover message.
I declare first my parameters, this works perfectly, but i dont understand the void loop with my funktion when i press the button. My Arduino compiler send the following error:

sketch_jan17a.ino: In function 'void loop()':
sketch_jan17a:165: error: invalid operands of types 'const char [7]' and 'const char_' to binary 'operator+'
sketch_jan17a:166: error: expected primary-expression before '.' token

Hi Dani,

Could you please format your ino correctly with ``` markdown or include in a gist... it s so hard to follow

cheers

hi, wifimanager just manages the connection and configuration of conenction
you need to be using wificlient to connect to an endpoint
something like

 // Use WiFiClient class to create TCP connections
  WiFiClient client;
  const int httpPort = 80;
  if (!client.connect(host, httpPort)) {
    Serial.println("connection failed");
    return;
  }

  // We now create a URI for the request
  String url = "/input/";
  url += streamId;
  url += "?private_key=";
  url += privateKey;
  url += "&value=";
  url += value;

  Serial.print("Requesting URL: ");
  Serial.println(url);

  // This will send the request to the server
  client.print(String("GET ") + url + " HTTP/1.1\r\n" +
               "Host: " + host + "\r\n" + 
               "Connection: close\r\n\r\n");
  int timeout = millis() + 5000;
  while (client.available() == 0) {
    if (timeout - millis() < 0) {
      Serial.println(">>> Client Timeout !");
      client.stop();
      return;
    }
  }

  // Read all the lines of the reply from server and print them to Serial
  while(client.available()){
    String line = client.readStringUntil('\r');
    Serial.print(line);
  }

  Serial.println();
  Serial.println("closing connection");
