The ‘golden hour’ is just subjective and varies between individuals and latitudes. Quite frankly these are all easy to derive and no developer would spend time doing this as pnbruckner has already done most of the work (that’s if you aren’t comfortable using the standard component as described above) in his enhanced sun component. Nadir - This is ‘midnight’ in the standard component Night - well your description is astronomical dusk which is defined as when the sun is 18° below the horizon, need I say more ? NauticalDusk - The definition of nauticaldusk is when the sun is 12° below the horizon, need I say more ? Sunset - This is ‘sunset’ in the standard componentĭusk - The definition of dusk is when the sun is 6° below the horizon, need I say more ? SolarNoon - This is ‘noon’ in the standard component An hour after sunrise in Florida is FAR differentt to an hour after sunrise in Alaska - you are better to use an elevation and work on that. GoldenhourEnd - This is a ridiculous statement as it depends on lattitude, the golden hour is a nominal name for a light effect that occurs with the sun very low in the sky. The atmosheric lens effect will mean that you can define a position of the sun above the horizon (which would be 16’ (16 minutes or 0.266666 degrees) above the horizon but due to the lens it will appear much higher) SunriseEnd - This is just made up, why would you want that ? Anyway this is virtually impossible to calculate, see : - Sunrise - Wikipedia Sunrise - Well that’s ‘sunrise’ in the standard component ![]() You can do ALL of these with the standard component (except for the dubious ones, I’ll note) NauticalDawn - nautical dawn (morning nautical twilight starts)ĭawn - dawn (morning nautical twilight ends, morning civil twilight starts) NightEnd - night ends (morning astronomical twilight starts) Nadir - nadir (darkest moment of the night, sun is in the lowest position) Night - night starts (dark enough for astronomical observations) NauticalDusk - nautical dusk (evening astronomical twilight starts) Sunset - sunset (sun disappears below the horizon, evening civil twilight starts)ĭusk - dusk (evening nautical twilight starts) SunsetStart - sunset starts (bottom edge of the sun touches the horizon) SolarNoon - solar noon (sun is in the highest position) GoldenHourEnd - morning golden hour (soft light, best time for photography) ends SunriseEnd - sunrise ends (bottom edge of the sun touches the horizon) Sunrise - sunrise (top edge of the sun appears on the horizon) (to be used for initial colour temperature and/or brightness of lights as an example - So when turning on the light, based on the position of the sun (or at least one of the fourteen states), you could decide you want to have light turned on less bright and warmer by your motion sensor (so that you’re not blinded in the middle of the night and you need to go )) Through this, we could either trigger on a solar state change or, query the current solar state. I would like to see this functionality in the Sun integration. I currently have a pseudo device from my Conbee II, which has one of fourteen states mentioned above. The example library I mentioned above also contains the moon’s phases, which could also be nice, but not necessary of course.Įdit: Added a link to the Sun integrationĮdit2: It appears I wasn’t very clear what I have in mind exactly, as per the discussion below. ![]() Nautical dawn (morning nautical twilight starts)ĭawn (morning nautical twilight ends, morning civil twilight starts) Night ends (morning astronomical twilight starts) Nadir (darkest moment of the night, sun is in the lowest position) Night starts (dark enough for astronomical observations) Nautical dusk (evening astronomical twilight starts) Sunset (sun disappears below the horizon, evening civil twilight starts) Sunset starts (bottom edge of the sun touches the horizon) Solar noon (sun is in the highest position) Morning golden hour (soft light, best time for photography) ends Sunrise ends (bottom edge of the sun touches the horizon) Sunrise (top edge of the sun appears on the horizon)
