Smart home aluminium windows 2026 — intelligent windows and doors with Somfy, KNX and Apple HomeKit

Why aluminium is the ideal material for smart home

When it comes to smart homes, the window material seems irrelevant at first glance. But in practice, aluminium has a decisive structural advantage over PVC: profile rigidity allows electric motors to be mounted directly in the frame or hardware system, without deformation over time.

A PVC profile deforms thermally by 2–3 mm at 40°C temperature variations — enough to jam a 24V motor mounted in the window frame. Aluminium has 6× lower thermal expansion, maintaining the tolerances required for automatic mechanisms over 20–30 years.

Practical conclusion: if you are building or renovating a house with a smart home vision, aluminium joinery is not an option — it is the only material that guarantees long-term operation of automatic systems.

Compatible automation systems for Alumil aluminium joinery

Somfy — the de facto residential standard

Somfy is the most widely used home joinery automation system in Europe. Native compatibility with all Alumil Supreme and Smartia systems.

Somfy motors compatible with aluminium joinery:

• Somfy Yslo Extend io — tubular motor for sliding and lift-and-slide doors. Force 160N, adjustable stroke, TaHoma Switch compatible.
• Somfy Chronis io — motor with integrated astronomical programmer. Automatic opening/closing at sunset/sunrise, no external hub.
• Somfy TaHoma Switch — premium KNX/io/RTS hub, full integration with BMS systems.

Nice — the competitive European alternative

Nice (Italy) is the second option by volume on the Romanian market. Slightly better value at entry-level motors.

KNX — the standard for premium projects

KNX is the open European protocol for building automation (EN 50090). Unlike Somfy and Nice (proprietary systems), KNX is an open standard — any KNX device works with any other KNX device regardless of manufacturer.

Choose KNX over Somfy when:

• New house project with complete automation (lighting + climate + joinery)
• Project budget over EUR 15,000–20,000 for automation
• Architect or systems integrator has specified KNX

Integration with major smart home ecosystems

Apple HomeKit

Somfy TaHoma Switch and Nice Home are natively HomeKit compatible since 2024. Windows appear as accessories in the Home app on iPhone/iPad/Mac.

Voice control Siri: "Hey Siri, close the bedroom windows"

Google Home & Amazon Alexa

Native compatibility via Somfy Connexoon or Nice Home. 5-minute setup.

Voice control: "Ok Google, open the terrace door"

Loxone (premium residential projects)

Most popular in Romania for premium residential projects. A complete Loxone project for a 200 m² house costs EUR 8,000–20,000 including hardware, programming and commissioning.

Recommended Alumil systems for smart home

Alumil S700 Supreme — lift-and-slide: ideal for smart terraces. Silent motor (< 45 dB), force 500N, opening up to 5,000 mm.

Alumil S350 Smartia — sliding: economical system for terraces and bedrooms.
