# Blinds azimuth

Guide on setting up sun orientation for the Smart Rule "Blinds adjustment according to sun" with detailed info on azimuth and window settings.

Last updated: 2026-11-06

To make the Smart Rule “**Blinds adjustment according to sun**” work for a window, enter the window azimuth (the compass direction the window faces, with North = 0º) in the advanced settings of the blinds or sliding shading element. You set it there together with the window height and the azimuth and elevation offsets, and you can measure the azimuth with a smartphone compass app or a physical compass. The rule is active only when the sun azimuth is within ±90 degrees of the window azimuth. Offsets account for obstacles in the direction of incoming sunlight.

> [!NOTE]
> The settings described on this page are necessary for the proper functioning of the **Smart Rule “Blinds adjustment according to sun”**.

## Sun orientation setup

Open the **Service settings** of the blinds or a sliding shading element and locate the **SUN ORIENTATION** section.

| **Attribute**                   | **Default values** | **Usage**                                        |
|---------------------------------|--------------------|--------------------------------------------------|
| **Azimuth of the window**       | 180º               | **Smart Rule Blinds adjustment according to sun**       |
| **Window height**               | 2m                 | **Smart Rule Blinds adjustment according to sun**, **Blinds level setting enabled**, **Mode “Depth of sun ray”** |
| **Distance from floor to window** | 1m                 | **Smart Rule Blinds adjustment according to sun**, **Blinds level setting enabled**, **Mode “Depth of sun ray”** |
| **Offset**   | 0º, 0º, 0º, 0º     | **Smart Rule Blinds adjustment according to sun**       |


## Azimuth

To determine the azimuth orientation of the window:
- Stand inside the room with a smartphone pointed outward through the window.
- The number of degrees (**North = 0º**) represents the azimuth.

## Recommended apps:
- **iOS**: Preinstalled **Compass** app, or **PV Optimizer & Solar Compass**.
- **Android**: **SunMoonTracker**.

It is recommended to use either a **physical compass** or an app with the ability to adjust orientation according to the sun's position, since buildings can cause strong **magnetic interference**.  

> [!NOTE]
> The Smart Rule **“Blinds adjustment according to sun”** is active only when the sun azimuth is within ±90 degrees of the window azimuth. If this condition – or other conditions specified in the **Smart Rule** – are not met, another Smart Rule with a lower priority will take control of the blinds/shading.

## Azimuth / elevation offsets

**Offset** should be set in cases where there are obstacles in the directions of incoming sunlight.

## Left / Right azimuth offset
Blinds seen from above: window azimuth 142°, sun azimuth 163°, noon at 11:42, left and right offset 8° each, an obstacle on the right.


## Upper / Lower elevation offset
Blinds seen from the side: sun elevation 54°, top offset 5° (a balcony above the window), bottom offset 8° (an obstacle in front of the window).
