open the curtains/blinds, when the sun comes up, sunlight gets in.

even if you want to control the time of day this happens, surely you realize that your body evolved according to the sun's timetable, and benefits from that timetable.

if you're not a day shift worker I understand completely.

Um I can open the curtains all I want, there's little sun in German winters out there.

The automatic part is also important since I need it to get up from bed.
