Are you talking about a physical LED, or an LED widget?
Is your switch a physical switch, or a button widget?

Which pins are these LEDs and switches attached to?

Pete.

  • physical LED, pin D6
  • physical switch , pin D1

I’m a bit confused by your interrupt service routine.
It won’t work correctly with recent ESP cores, because you’ll get ISR not in IRAM errors.
Also, as it’s HIGH trigger, the ISR will only be called when the pin is HIGH, so I don’t see why you’re checking if the pin is HIGH in the ISR.
