You could clean it up a bit more, like have separate functions (with descriptive names) for initializing your buttons, LCD and servo, maybe another for the WiFi stuff. I see you also have stuff for your password, which can also be its own function call. It would probably be best to make a copy of the sketch first, this way if something does go wrong, you don't lose a working version.
You can do the same for everything in the loop and have separate functions for those parts too.
Make it readable for someone who has no idea about coding, than can go through and at least understand what each part does based on the name of the function.
A lot of lines like this "(req == "/led/on")" can probably be moved into a switch statement instead of IF statements.
Things like that can make a big difference.
Maybe not a good idea to share your passwords...
Why? Its only a hotspot through a phone, and the whole smarthouse thingy is in a miniature form, its my graduation project.
Since you did not develop the menu logic as the beginning part of your program, I suggest you write a completely separate program to develop, test and debug your menu system. Then incorporate that menu logic to your existing program.
Been there, done that, and apparently failed too.
It's not about the seriousness, it's just that you don't do it. For all I care, put up posters where you live with your hotspot login, but don't do it here. Hard to grasp I know, but you can do it.
Why argue with people offering help? Rather odd way to get help. Why if you "have a working code" do you need help correcting it? What does it do? What does it not do? From where did you copy it? Why did you comment-out the Neopixel object initialization but leave the code?
