Position of horizontal roller shader

Hello,

I have a shelly2.5 to control the open and close of the balcony shader and i can manually stop it to the desired position.

Any ideas on how to schedule and position the opening of the shade at a desired position based on the time of the day?

eg: during night it will be closed fully. During daytime, as the sun is moving, the shader will open in intervals until sunset.

OK... solved...

Calibration worked, and i can now set the schedules so that every 30 min or so to open further the shader up until the time that the sun does not get into the room. On the sunset it will close it completely.

I am closing it.
