Piston refresh help

#1

Hi everyone,

i have a question. I have a piston that when back door is open the light in my shed comes on. works great. but with the sun on its way i want it to only come on it lux drops below x. the problem is that i will probably open my back door when lux is below that number (so the light comes on) but the door will be open all day meaning so will the light. is there a way you can get a piston to refresh after a certain period of time meaning lit rechecks the conditions and later in the morning it would turn off?

thanks!

essentially i want something like the below

door open and lux below x turn on light. but i need the piston to resfresh, say every hour so it reasses the conditions
