A jinja macro to track the position of a vertical cover based on the sun position to block out direct sunlight.
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 to a .jinja file in your config/custom_templates folder. Run the homeassistant.reload_custom_templates service call to load the file.
