Close led fans on the night

Good morning
I am new to using programming, I would like to make the LEDs on my fans close at night
I can’t find the possibility of doing it. I saw on another forum a possibility for the task manager to change the color to black, for example with the good night effect! , but when I do the command in the task manager it gives me an error, I use the following command: "/k “start signalrgb://effect/apply/GOOD NIGHT! && exit” thanks for your help

If you are using Task Scheduler, you should be able to do this by using


in the “Program/script” box and entering

/c start signalrgb://effect/apply/Good%20Night!

in “Add arguments” box.

I hope this helps,
