Hi, I am using scheduled watering to fill capillary boxes. I have a floating sensor mounted and can connect and set it up as an interrupt, based on instructions in other responses.
I am however not sure how I can stop the watering immediately, when the switch flip? Any recommendations?

Ciao Angelo, very helpful - grazie. I think I have a good understanding now and will test my setup as soon as I get a chance to go to the summerhouse.
Have I understood your comment "So until the Pin is to GND the pre-emptive status will be extended of the "duration of pre-emptive..." indefinitely" correctly, when I conclude that the pre-emptive condition will remain (valve closed) as long as the level is GND? My first edge is going from positive to GND and hence level will remain GND, I assume.
