roller shutter control

Hello
I’m new to this forum and recently owner of a vera3.
Here’s a question for creating a scene. ???
I control my blinds with sunrise and sunset times.
How could I implement the following scene. Blind 15 minutes after sunrise complete but not open before 6:00 am. Blind 15min after sunset completely but do not close before 7:00 pm.

sorry for my bad english
many thanks

hello
Have now found that I can realize my wish with the Program Logic Event Generator. But I am absolutely new and have no idea to work with the plugin.
Is it possible a small step by step briefing to create for my required scene. I hope I can later create their own workflows. I would be very grateful

Nobody can help me? :-[

This is an excellent thread containing documentation on the use of PLEG:
