# Auto Sun Blind

Automatically control your sun blinds via home assistant based on the position of the sun.

This repo contains a `custom_template`, `blueprint`.

This [forum post](https://community.home-assistant.io/t/automatic-blinds-sunscreen-control-based-on-sun-platform/573818) explains the math behind the project.

## Custom Template

`version 1.0.1`

A jinja macro to track the position of a vertical cover based on the sun position to block out direct sunlight.

### How to import

Home Assistant 2023.4.0 or higher is required to use custom templates.

You can install it using HACS. HACS only supports custom templates in `experimental mode`. Click on the button to go directly to the right section.

Manual install is done by copying the contents of [`auto_sun_blind.jinja`](https://github.com/langestefan/auto-sun-blind/blob/main/auto_sun_blind.jinja) to a `.jinja` file in your `config/custom_templates` folder. Run the `homeassistant.reload_custom_templates` service call to load the file.

```yaml

{% from 'auto_sun_blind.jinja' import 'auto_sun_blind' %}

{{ auto_sun_blind() }}

```

## Blueprint

`version 1.1.2`

This project includes a blueprint that you can use without setting up a sensor.

[![Open your Home Assistant instance and show the blueprint import dialog with a specific blueprint pre-filled.](https://my.home-assistant.io/badges/blueprint_import.svg)](https://my.home-assistant.io/redirect/blueprint_import/?blueprint_url=https%3A%2F%2Fgithub.com%2Flangestefan%2Fauto-sun-blind%2Fblob%2Fmain%2Fblueprints%2Fauto_sun_blind.yaml)

Features:

    - Multiple cover control (`since v1.1.0`)

    - Easy variable control with sliders

    - Time-out to save battery or reduce the amount of changing the cover position

    - Minimum percentage change to prevent the amount of changing the cover position by small percentage changes

    - Add additional actions such as notifications to the automation

    - Add conditions like the time of day, minimum amount of lux

    - Default height can be templated, which allows for conditions if the sun is not in front of the window.
