Steuerung der WR-Kennwerte

Testcode.cpp

Hello everyone,
Reducing the inverter power is easily possible via a PC after opening the web portal if the OpenDTU is operating as an AP.
However, I would like to save time and am looking for a way to do this with the push of a button on an ESP32.
It is possible to read the current data without any problems, but I cannot send an HTTP POST to the OpenDTU to temporarily set the power value to 10%. The enclosed code establishes a connection to the OpenDTU, but the value is not adopted, regardless of whether it is a percentage or an absolute value.
Integration into the home network is not possible (Wi-Fi power).
What is sent from a PC when the "Set limit temporarily" button is pressed, and can this be replicated with an ESP32?

Regards, Ingolf

PS: Answers are also welcome in German

Hallo Tiese,
vielen Dank für den schnellen Hinweis, allerdings weiß ich nicht mehr geanu, ob ich an den Beispielcode, den ich jetzt benutze, über diesen Link gekommen bin.
Es war ein fast komplettes Beispiel, in dem nur die WLAn-Zugangsdaten einzutragen waren.

Viele Grüße aus dem Harz
