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. :)

@dominic can you look to see if there are errors in the console? Two places you can look: Errors from node_helper.js will be output to the pm2 logs. Type pm2 logs mm to monitor this. The second place to look for errors is in Electron’s console. Start MagicMirror in debug mode with npm start dev and you’ll get the screen divided into to halves. On the right side you’ll see a white panel. Click on “CONSOLE” and if there are any errors there they will be in red.

and with pm2 logs mm this one

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.

You have to cd in the MagicMirror directory first, then run npm start or npm start dev
