Smart shading: more than just opening and closing blinds

Motorized blinds are easy to install. Smart shading logic that actually improves life and reduces cooling load is harder, but worth it.

The inputs to plan for. Sun position by facade (calculated by a logic block from latitude, longitude, and time of day, or fetched from a weather service). Outdoor lux per facade (from a roof-mounted sensor or, more commonly, derived from sun position). Wind speed (from a roof anemometer; required for safety). Rain detector (for awning retraction). Frost detection (for blind safety in winter). Indoor temperature (so cooling priority can override view priority).

Blind actuators with slat tilt. A blind on a south facade in summer can be lowered fully but tilted to let in some light without solar gain. This is where slat-tilt actuators earn their cost. A simple position-only blind can shade or not shade; a tilt-capable blind can shade and still light the room.

The core scenes. A summer-morning routine that lowers blinds on south and west facades to about 60 percent and tilts them to block direct sun while allowing diffuse light. An autumn-afternoon routine that opens blinds fully when the sun is low and the room benefits from passive solar warmth. A storm protocol that retracts every blind when wind exceeds 60 km/h.

Manual override and timeout. Whatever the automation does, the customer must be able to override with a single button press. The override stays in effect until either a timeout (typically 2 to 4 hours) or the next automation event of the day, whichever the customer prefers. Without manual override, customers eventually disable the automation entirely.

Visualisation feedback. A small dashboard showing the current state of every blind, plus a history of why each blind moved (sun, wind, manual, scheduled), helps the customer trust the system. Without this transparency, mysterious blind movements feel intrusive.
