@GHLasse Thank you. I will test it later.

Very nice

@Mykle1 Ah Thanks :D, now i have the console, but there is no error.

ach with the other code

 mqttDiv.innerHTML = "< span class='fa fa-calendar'>< /span>" + this.mqttVal.toString().concat(this.config.postText);

i get a symbol, only with the var version, it does not work.

Now with this code ( is the original code with added css file and with your part) i only get the text “loading MQTT DATA” before it has still worked with your code. Maybe it is to late or i don´t see the error…but if you can be so nice, can you add tell me wehre my error is and can you add the varribale code ? And thank you very much for your help.

   mqttDiv.appendChild(symbol)
   mqttDiv.appendChild(textEl);

   wrapper.appendChild(mqttDiv);

   return wrapper;

     this.updateDom();
   }

   if (notification === 'ERROR') {
     this.sendNotification('SHOW_ALERT', payload);
   }
 }

});

It works!! Ehm is it possible to make it varriable, so i can choose the symbol with an entrie in the defaults ?

Module.register('MMM-mqtt', {

 defaults: {
   mqttServer: 'mqtt://test.mosquitto.org',
   loadingText: 'Loading MQTT Data...',
   topic: '',
   showTitle: false,
   title: 'MQTT Data',
   interval: 300000,
   postText: ''
 },

Thank you! I will test it later.

@j.e.f.f thank you. But one question, who can i call the Symbol, so that is Displayed before

 var mqttDiv = document.createElement('div');
    mqttDiv.innerHTML = this.mqttVal.toString().concat(this.config.postText);
    wrapper.appendChild(mqttDiv);     // here add  the symbol

@j.e.f.f i try to ad a sysmbol as a font . But if you have an other idea, then it is ok.

Hi i want to add symboly/icon in a modul. But I can not do it. The symbol is said to be the result or it can be set over the config…can any one help me pleas ?

This is the module code.

      this.updateDom();
    }

    }
  }

});

@BenRoe thanks for the answer. I have removed the squared brackets but it is still the same. The modul will not displayed. Do you have an other idea ?

@Woody Thank you, yes i think my originlproblem is not the authorization.
Do you have any idea., what it could be ?
