The blinds in my bedroom in my flat should open automatically and gradually to wake me up. Opening time should be setable via webinterface and may depend on calculcated sunrise times as well as on weather. Since it's a rented flat, all changes must be easily reversible or easily be handed over and maintainable by a non-technical person.

• Rollladenmotor
  This was the first option I looked at. Could be easily controlled with a µC and some relays. Decided against it because:
  • reversing it is at least as much work as installing it
  • handing it over to another tenant would mean adding easily controlled and maintainable commercial buttons and controller hardware, which I wanted to avoid
• Superrollo GW60
  • decided on this, since it seemed like a easily installed plug in solution
  • the option to add a ZB40 433MHz remote suggested the GW60 should be very hackable.
