Blind & Shading Control
with Loxone.

Automatic sun protection by azimuth and elevation — wind protection in real time, slat tracking for daylight guidance and passive heat protection per GEG §14. Cloud-free, low-maintenance.

Request consultationarrow_backBack to overview

Loxone shading control calculates sun azimuth and elevation from GPS coordinates and controls venetian blinds, external blinds and roller shutters fully automatically — without cloud, without manual intervention. A wind sensor protects sensitive external blinds in gusts above 40 km/h. Slat tracking guides daylight onto office ceilings and saves up to 40% in artificial lighting costs. HELITS realises shading projects in Bavaria, Austria and Switzerland — particularly relevant for the Foehn conditions in the Berchtesgadener Land.

Shading explained —
Sun, wind & slats.

Sun position calculation without cloud

Loxone calculates the azimuth and elevation of the sun from GPS coordinates locally on the Miniserver — for every moment of the year, without external API. If a facade is directly sunlit, the shading on that side automatically extends. In winter with a low sun position, the shading stays up so solar heat gains can be used — fully automatic seasonal adjustment without manual intervention.

Wind protection in real time

A wind speed sensor (Loxone weather station or 1-Wire wind gauge) provides real-time wind data. If the wind speed exceeds the threshold (adjustable, typically 40 km/h for blinds, 25 km/h for awnings), Loxone immediately retracts all exposed elements — protecting slats and fabric from damage. After the wind drops, a safety period applies before re-extension. Particularly relevant for Foehn conditions in the Berchtesgadener Land.

Slat tracking for daylight guidance

For venetian blinds, Loxone controls not only the height but also the slat angle dynamically according to the sun position: direct radiation is blocked, diffuse light is reflected via angled slats onto the ceiling. The room stays bright without glare — artificial lighting demand falls measurably. Relevant for office spaces per DIN EN 12464-1 and DGNB/BREEAM green building certifications.

Climate coordination: shading + heating/cooling

Loxone coordinates shading with heating, cooling and ventilation. In summer: exceeding an outdoor temperature threshold causes south and west facades to shade preventively before the air conditioning responds — passive heat protection per GEG §14. In winter: sunshine with positive outdoor temperature keeps blinds up for solar gains. Window contacts stop shading when ventilating.

home_iot_device

SFH south facade

Venetian blinds extend automatically when the sun shines, retract at night. No more manual operation — roller shutters also as burglary protection from 11 pm.

business

Office glass facade

DALI lighting + venetian blind slat tracking coordinated: daylight used, screen glare eliminated, air conditioning relieved.

groups

Hotel room morning sun

Blinds close automatically at sunrise on the east facade. Wake routine opens slowly at the desired time — gentle awakening.

eco

Conservatory Alps

Glass roof shading + ventilation combined. With Foehn wind gusts (BGL) immediate retraction. Awning only opens after 10 minutes of no wind.

Shading expert
in the Berchtesgadener Land.

The Bavarian Alpine foothills — especially the Berchtesgadener Land — are known for strong UV radiation in summer and pronounced Foehn conditions with sudden wind gusts. Our shading configurations are tailored to these weather conditions: lower wind protection thresholds, fast retraction responses and seasonal sun position profiles.

From Anger (Landkreis BGL) we personally manage shading projects in Bad Reichenhall, Berchtesgaden, Freilassing, Traunstein and Salzburg. In the rest of Bavaria and the DACH region we coordinate projects remotely with local electrician partners.

Frequently asked questions

Everything about Loxone shading control.

How does the sun position automation work in Loxone?

expand_more
Loxone calculates the exact azimuth and elevation angle of the sun from the stored GPS coordinates of the building for every moment of the day and year — without cloud, without external API. If a facade is directly sunlit, Loxone automatically extends the shading. During overcast conditions or negative outdoor temperature, the system can be configured to use solar heat.

Which shading types does Loxone support?

expand_more
Loxone controls all motorised shading products: venetian blinds (with slat tracking), external blinds, roller shutters, zip screens, awnings and conservatory glass roof elements. Control via Tree Extension (cable), Shutter Extension (relay for 230V tube motors) or KNX. Existing Somfy motors with RTS protocol can be integrated via a bridge.

How does Loxone protect shading in wind?

expand_more
A wind speed sensor provides real-time wind data. If the wind speed exceeds the configurable threshold (typically 40–60 km/h for external blinds, 25 km/h for awnings), Loxone immediately retracts all exposed shading. After the wind drops, Loxone waits a safety period before extending again.

What is slat tracking and what is it used for?

expand_more
With venetian blinds, Loxone automatically adjusts the slat angle to the sun position: direct radiation is blocked, diffuse daylight is reflected via angled slats onto the ceiling. The room stays bright without glare — artificial lighting demand falls by up to 40%. Relevant for office spaces per DIN EN 12464-1.

Can shading be integrated with the Loxone heating and cooling system?

expand_more
Yes. Loxone coordinates shading and air conditioning or heating together. In summer, south and west facade blinds extend preventively before the air conditioning needs to switch on (passive heat protection per GEG §14). In winter, blinds stay up to use solar heat gains.

How does shading control work when the internet fails?

expand_more
Loxone works completely offline — sun position calculation, wind sensor evaluation and all automation rules run locally on the Miniserver. No internet, no cloud service needed.

Can Loxone shading be retrofitted in existing buildings?

expand_more
Yes. Existing 230V tube motors (roller shutters, blinds) are integrated via the Loxone Shutter Extension by relay — no motor replacement needed. For new installations we recommend Tree-compatible motors or KNX motors with existing KNX infrastructure.

What does a Loxone shading system cost?

expand_more
Extending an existing Loxone system: typically €600–1,500. New installation including Miniserver for a single-family home with 8–12 elements: €3,500–6,000. For commercial buildings on request. We provide a transparent quote after a free initial consultation.
