Embed mqtt in EW GUI Application

Question

Is it possible to communicate with MQTT from the GUI/Application?

Unfortunately I haven't found a direct way so far.
I wrote a Python script that writes received messages to a text file. I query this text file from the GUI and evaluate the string.

Hello Alexander,

out of the box support for MQTT is not provided. But you can implement the necessary communication. Doing this please have in mind, that GUI applications created with EW have no access to other external code, hardware, file system, network, etc.. Therefore, to exchange any data you implement first an adequate interface. The following chapters address the corresponding aspects:
