Everything runs smoothly when internet is connected both the manual control and online control works seamlessly but when internet is not connected that is when wifi is off there is 2-3seconds delay in response for manual switch control-all what should happen is that the esp32 should read a digital pin as high when switch is on and turn on the corresponding digital pin this happens rapidly when wifi is connected whatsoever.. is Esp32 responsible for this ..

please go through the below code and check if there is a mistake which is causing the delay.

is there any method to rectify this..
