I'm a bit tired of setting my screen contrast and brightness manually for each screen every morning and evening, so I'm looking for a way to automate this.
I'm already using F.lux and it's great, but it only changes color temperature. In the night, I still find my screens too bright. Recently I found Screenbright which does exactly what I want, that is, changes hardware brightness and contrast, and works from the command line as well.
Now I'm off to automate this. Is there a way to set Windows task scheduler to trigger task on every sunset and sunrise? I can set it to a fixed time every morning/evening, but that's not as elegant as I want it to be.
