Hello,
As a rather new developer in Arduino and it must be +25 year since I lasted used C++ I do have sort of frustration if I choose the right WEB server for my ESP32C6 solution.
Here is the challenge I seem to have: I have 8 curtain motors (Somfy Glydea 35 RTS) which I control from an ESP32-C6 board (Sparkfun Quick). Of the 8 ESP32-C6 cards, 5 works perfect after 3 years or something. So that leaves the 3 that still kind of works, however the response from them is always delayed, between 1 to 3 seconds, and sometimes it just fails. It is not often it fails, that is maybe once every 6-9 months, however the delay is a bit more frustrating. Now all 8 cards run the exact same compiled software. Well except one of the 3 above which I kind of hammering with different examples of web server to see if that changes the challenge.
Se it like this: Either one has direct response (the 5 working ESP32-C6) or the command sent is delayed with 1-3 seconds. For me there is no reason for this strange behavior, the same kind of ESP-card and compiled software (with the exception that one of the remaining 3 is some sort of development work on - it does however never change this delay behavior). But I still wonder if my very old knowledge in C++ is the reason this happens? Or if for some reason I somehow managed to set the ESP32-C6 into some sort of low power CPU setting (no need, it is powered over 230v outlets into the Glydea motor, which converts it to 3.3v which I feed direct into ESP32-C6 pin for 3.3v - and it has more than enough to drive the card, I even tried a stabilizing solution, no change).
So what I would love is for someone to check my code, and tell me what I might improve - or if I should change web server (webserver.h - but I have tested the Async version also - no difference)? Any ideas or comments are welcome - and please do remember it is a looooong time since I used C++, consider me a beginner (heck I have used IBM Mainframe Assembler for just a few years ago so I seem to know that better, although I am actually more of a SQL person nowdays).

And for reference I have updated Arduino to Arduino IDE 2.3.8 - no errors/warnings when compiling.
