Porch light on infinite loop, help!

[1029cheatham]

1) Give a description of the problem
light is switching on and off in a loop

2) What is the expected behavior?
go on if it is between 1 hr before sunset and sunrise and turn off other times (if someone turns the light off physically at night i want the light to come back on and same for turning it on during the day)

3) What is happening/not happening?
when it gets to one hour before sunrise the light turns on and off in a loop

4) Post a Green Snapshot of the piston.png)

5) Attach any logs (From ST IDE and by turning logging level to Full)

I think your math was overlapping & causing the loop…
(if on, turn off… if off, turn on)

You could simplify your piston by using something like this:

Although normally, I do not recommend taking this approach because you are basically turning a smart bulb into a stubborn bulb. Other variables (including free will) will no longer be considered…

Unless you change something later,
you will never be able to make the bulb do anything…
That bulb will be locked… 24 hours a day…
(with the exception being color & brightness changes)

Please understand that if you decide to go this route, you’ll have to be careful that none of your pistons, scenes nor routines try to control that light switch at all.
(or you may unintentionally re-create the loop once again)
