About

Sun2 is a custom integration that creates sensors for sun-related events at one or more locations. It adds sensors for events such as dawn, dusk, daylight, night, azimuth and elevation, plus binary sensors that switch on when the sun's elevation is above a chosen threshold. Each location has its own latitude, longitude and time zone, and defaults to the Home Assistant location if none is given. Observer elevation can be set above ground level, or an obstruction such as a mountain can be described for the sunrise side, the sunset side, or both. Actions can reload the YAML configuration, read a location's options and update them. It runs locally and is set up through the UI or YAML, after being added as a custom repository.
