Rep Power: 22 gripmarketing is on a distinguished road
Roof window companies make automated closures (electric motor with hinged arm) that are attached to the blinds that can be further automated by making on/off mechanical switch that is mounted in door frame.

I know because I have a series of roof windows in my home with automated blinds - I even have 4 of them in the kitchen set to a timer and light detector as well as override wall switch.
