ok, first define an override variable, when you want and do not want to open and close your blinds on the calculations

Secondly, calculate the average value you want to use for your lux value

Also calculate the bandwidth how to move the blinds up and down, (if not they will keep moving.)

Each blind can have their own length you can adjust this via this.

bason upon this, you can move the curtains up and down. (since this is pased in a app of @Arie_J_Godschalk , i also show the debugging part, in case of issues.

Please take note, this is how i have done, it but there are a lot of way’s to do this, since a lot of this also controls the lights etc etc etc.  
enjoy toying around!

cheers,
