This is about A4 Board from KinCony with ESP32 and connected to Loxone miniserver, I planed to create the code for all the board’s functions to use it connected to Loxone miniserver and install it in my green house on my balcony

Currently I am trying to create the code in Arduino IDE and this is the partial code I managed to make it until now:
