Hey Siri, extend the sail!

Electric sun sail, smart control: this made-to-measure Doppel-Dreieck and Trapez sun sail is easily controlled by app, Siri, Alexa or Google Assistant – automatic weather response included.

The terrace is a key part of the house – with an infinity pool and a direct view of the mountains. At the same time, the large areas of glazing heat the interior heavily. Conventional answers such as awnings or parasols were out of the question: they would have spoilt the clean architecture and restricted the view.

Two made-to-measure sails – a Doppel-Dreieck and a Trapez – span the entire terrace. The shapes were matched exactly to the building, to ensure optimal shade with minimal loss of view.

Control is fully automatic or by voice command:
Siri, Alexa, Google Assistant – on command the sail extends. Light and wind sensors handle automatic weather response, with no manual intervention.

NUM 1

Individually made to measure

The Doppeldreieck sail shades terrace and interior without restricting the panoramic view of the Allgäu Alps – the sight stays clear.

NUM 2

Smart home – app, Siri, Alexa

Posts and brackets in anthracite, clad in wood, recede visually. The shading feels not technical, but part of the house.

NUM 3

Fully automatic & weatherproof

A sun sensor and wind sensor control the sail: out in the morning, in at night. In storms above 20 m/s it safely retracts on its own.

NUM 4

Better indoor climate

The sail cuts the heat on the terrace and in the living area – with no external blinds. The large glass surfaces stay fully clear.

Conclusion

This project shows how modern sun-protection design and smart-home technology can merge: comfortable, energy-efficient and lastingly reliable. An electric sun sail by LET that fits seamlessly into daily life – and, if you wish, simply responds on command. The result is an outdoor space that feels natural and adapts to your needs at any time.
