thank you very much for this answer.
I made a try andI succeed stoping the flow at the enf of a timer with the only if condition.
but this has a default : it only stops the flow at the end of the current timer; which means it's not a real interruption, which means, that I cannot restart again the timer from the start.
I have exactly the same issue than there
and to be honnest I Don't really understand your full explanation there to solve this request.
My kids Always let the light on in there room. so I want to put a timer
"If light ON during 45mn then stop it"
but if you go out and stop the light manually and you come back after 10mn I want to restart it for 45mn.
with the current timer function, if you go out of the room at 30mn, you stop the light then you come back at 40mn, the light will go on only for 5mn because the old timer is still running.
adding an interrupt option or restart option in the timer would really be great…
I am discovering every day what we can do with stringify, and really it's a super great programm !
