Trigger an automation according to weather conditions

Hi all! First post here…
Coming from Vera and Shelly, I’m using HA for some time. Been doing most of the stuff by myself and trying to learn from many places.

But I’m struggling to do one thing… trigger an automation according to weather conditions.
Here is the problem:
I have two scenes for my roller shutters. One that opens to a certain level when its sun and another that opens to a different level when its rain.

What I want is to automatically trigger one of the 2, from Monday to Friday, at 7:30 am, according to the weather forecast.
Can someone please guide me?
Thank you!
