The current “sun” trigger for automations is limited to the events “sunrise” and “sunset” with an offset. It would be benefitial to be able to supply a desired sun angle instead of “sunrise” or “sunset”.
There currently exists work around to get this behaviour (via the solar_angle or elevation attribute of the sun) however this has some shortcomings ( Solar angle or sunrise/sunset? ) it would be nice to have it built in and easily accessable
(Note: the FHEM module SUNRISE_EL https://wiki.fhem.de/wiki/SUNRISE_EL provides a nice way to reference target solar angles - however since HA already has the sun automation trigger platform it would probably be nice to add this functionality to the “sun” trigger)
