Functions run by start automatically

[kaffemitmilf]

hey, Im currently programming a wemos d1 pro (esp8266), using the Arduino Iot cloud (message is a Iot var). As soon as I start the programm it starts to call the onMessageChange() function by its own.

Does anybody know a fix for this?
I know, my code is ugly af right now, but I am in a hardcore debug proccess xD

Thanks!

  Arduino IoT Cloud Variables description

  The following variables are automatically generated and updated when changes are made to the Thing

  String message;

  Variables which are marked as READ/WRITE in the Cloud Thing will also have functions
  which are called when their values are changed from the Dashboard.
  These functions are generated with the Thing and added at the end of this sketch.
