I've created an API that returns the altitude and azimuth for my hometown at the current date and time.
(see also http://www.wolframalpha.com/input/?i=sun+azimuth+altitude+7.41E+49.23N for results)
But how can I create a API that returns the time when the sun is for example @ azimuth>=175°, or @ altitude >= 20° today for the given location?
This would save a lot of API requests over the day :-)
(Purpose: Arduino project (with the Particle Photon) for home automation, driving shutters/blinds for shading of objects and energy harvesting)
Thanks in advance!
