Hi, Is there a problem in server blink I have a problem with the delay of the response of the server with my projects, although the speed of my Internet is very high

Thank you, Mr. Pete.
When I turn on relay or turn it off, I wait about three or four seconds for the command to be executed. I don’t know exactly where the problem is.

Local or Cloud server?
Code?
Phone connected to Wi-Fi or GSM?
Android or iOS app?

Please edit your code to use the correct triple backtick characters at the beginning and end of your code.
Triple backticks look like this:
