Hi, while we’re on this topic.
Has anyone tried to work out an algorithm to calculate slate position of venetian blinds? Given the orientation of a window/blind, and the solar altitude and azimuth (given in post above).
What is the optimal slate position to avoid direct sunlight?
I’we been playing with some calculations. Even tried to “reverse engineer” observations from a major brand “KNX Wetterstation”, but never really got hold of it. Anyone with good experiences on this?
Any suggestions on how to approach this is welcome.
E.g. Is there one formula?
Should i use a lookup table with different altitude- intervals for different azimuth “ranges”?
Should i use a combination?
