Hy there,
i have a switch at the door to control the status. If the door is locked, the switch closed the contact an a led is lighting. I want to use this Signal at my NodeMCU with EspEasy and Domoticz to see the Status.
Can anyone help me pls?

Use a multimeter and see what voltage levels are used for the led. You can then decide if that voltage is enough to monitor the status of the switch. Either digital or the voltage is 0..3.3V or analog of it is below needed 2.8V (if I remember correctly).

I have build tehe Szene at a Breakoutboard with another Switch. But everytime i push the button, the status changed. But I want to hold the Status so long the switch is pushed.
And it doesn't work. tehe Cicurit is : D5 -> Switch -> Ground.

Maybe change switch type in device tab on ESPeasy.
