I have a doorsensor that I misuse to detect the doorbel button being rang. Its a Fibaro that next to the magnetic input also has a binary input.
It’s always ‘on’ and if the doorbel is pressed it’s ‘off’. I can’t change the wiring.
Is there a way -at least for the interface- I can reverse the state? So it shows 'off" when the sensor is on and the other way around?
