How can I use this to support top/down bottom/up shades? Whese shades can block n area from a certain top point until a certain bottom point.. Like Duettes (vrom Hunter Douglas) or others

Describe the solution you'd like

calculate the top position and bottom position (in % open or closed from top or bottom) based on sun angle to block certain area of the room, or a default 'open' position that respects our privacy at day and close it at night,

Describe alternatives you've considered

Currently I use scenes for this toghether with a light sensor

Additional context

I use sunblinds to block direct sun on certain furniture as the UV light can harm the colors of my furniture. At the same time I want as much light in the room to warm it up and illuminate it (up to certain level). Folowing the sun position would giive an optimum balance between UV protection and heating/illumination. Also,, we can define a setting that will give us enough light above and below the shade whil maintaining some privacy for prying eyes. At night we want the shades being closed.
