HS/FS - √ - Illuminating only when it is dark

[Warichet]

Hi,

I'm willing to illuminate my drive way when a car enters the property.
I've no wheather station or light sensor.

I would like to illuminate only when it's dark.
I could do this with the UZSU but I want a variable time, i.e. days are getting shorter in the winter and longer in spring.
Any suggestion about how to do that ?

I know there are several Baustein about sun position, could the "Sonnenuntergang" do the trick ?
If yes, what about the "Versatz" ? is it a delay after the sun goes down ?

Thank you for any hint

Hello Raymond,

in Aviation ^night ops start +30mins after Sunset. Sunset would be available via SunPosition, elevation <= 0.

Best regards

OK, fine
Which Baustein would you recommend to do the trick ?

19820 SonnePur from MatthiasS. It even has a customizable Twilight-Output, where you can parametrize the angle below zero.

Hi Raymond,

you don't need any logic module for this, the UZSU will do the job. I add some screenshots, so you will know where to do the settings.
Sunset, sunrise, offset, with random - all included. Let there be light!

[Warichet]

I add some screenshots, so you will know where to do the settings.

Sorry, you lost me.
I don't even recognize the menus you are showing.
I'm using 2.5 standard, no QC.
Are those menus specific to the QC ? or did you add some features ?

[Taxus]

I don't use the QC. The design might be incidentally similar .
Just create a new symbol and assign the action 'Universal-Zeitschaltuhr öffnen'.

Hallo Rainer,

danke fuer die Info. Was die UZSU so alles kann, man lernt nie aus ;-)

Hi Rainer,

Just create a new symbol and assign the action 'Universal-Zeitschaltuhr öffnen'.

Sorry to be a pain
I can indeed create a new symbol and assign the action 'Universal-Zeitschaltuhr öffnen' .... but there it stops
I don't see the relation with your previous screenshots
Should I create a new entry there ? (you might guess I'm not using the UZSU every day )

Thank you for your patience

[Taxus]

Did you assign an existing UZSU in the Tabsheet "Universal-Zeitschaltuhr", e.g. "UZSU WWSLT" ?
Then upload your Project and klick the newly created symbol. Voilà!

What about adding WWSLT to the List of Abbreviations???

Cheers Stefan
p.s.: just kidding

I'm happy to know it works for you.
For me, it's like doing a puzzle with pieces from another play, obviously they will never fit.

I give up !

Do you have a pointer to the help file of that Baustein, please ?

Real programmers don't do documentation

Sorry, there is none.

But it is quite easy: It shows the location of the sun (azimuth and elevation).

Regarding elevation, there is a trigger output: Normally its getting dark if sun sets There are different grades of darkness according to the angle of the sun below the horizon. These angles are called:

Crépuscule nautique [modifier]




Près du crépuscule au Mexique.


Le crépuscule nautique est la période où le centre du Soleil est situé entre 6° et 12° sous l'horizon.
Il s'agit du moment où les étoiles de deuxième grandeur deviennent visibles ; en même temps, en mer, la ligne d'horizon est toujours visible permettant ainsi de faire un point astronomique avec les étoiles. À la fin de cette période, en soirée, ou à son début, en matinée, les dernières ou premières lueurs peuvent être discernées dans la direction du Soleil.
Crépuscule astronomique [modifier]

Le crépuscule astronomique est la période où le centre du Soleil est situé entre 12° et 18° sous l'horizon.
Pendant le crépuscule astronomique, et dans le cas d'un ciel dégagé de toute pollution lumineuse, les étoiles les plus faibles visibles à l'œil nu, vers la magnitude apparente 6, apparaissent. Du point de vue astronomique, il subsiste cependant suffisamment de lumière pour que les objets diffus comme les nébuleuses ou les galaxies ne puissent pas être observés dans des conditions satisfaisantes, même si cette lumière est imperceptible à l'œil nu.
Le soir, la fin du crépuscule astronomique marque le début de la nuit complète ; le matin, c'est la fin de la nuit, l'apparition des toutes premières lueurs de l'aube.


Zitat Wikipedia


So the trigger output in my logic module is set to 6° by default. Depending on your location it could be necessary to enter a differnt angle.

Grmbl, I think I've heard this before

But it is quite easy:.

It might be me being more dumb then the average

All I want is to enable the light be switched on when it is dark (so depending on the sun's position.

Do you think the output "Höhe" will do the job ?
If there is any postive number there, the sun is present and I disable the lights on.
If there is 0 or any negative number there, the sun is absent and I enable the lights on.
Is that correct ?

I see there are 2 other Baustein Sonneuntergang and Sonneaufgang, which have to be combined for a 24Hr cycle.
Any chance the logic below is correct ?
