I see that there is an ‹ in progress › request for a scene trigger based on the sun’s azimuth and altitude.
I would also find it useful to be able to retrieve azimuth and altitude as a variable, usable later in the scene.
Indeed, these two pieces of information as a trigger will allow you to open or close a shutter at just the right moment. But if you were away, shutters closed, and you come home, it is in the form of a variable that you would need azimuth and altitude to be able to make ‹ variable conditions › and open the shutters in a relevant way.
