How to use an "at" command with a "Perl" command?

[Fonz]

Hi,

I would like to use the Twilight module.

I know its working because I can type...

get myTwilight ss_indoor

Into the Fhem web interface, and it returns a time.



However I am unsure of the syntax to use with a "at" command as...

define b6 at *{myTwilight ss_indoor} set Lamp on

Does not work.

Could anyone help me with the syntax for this please?

Many thanks,

Fonz

Hello Fonz,

for me it works as follows

define b6 at *{ReadingsVal("myTwilight","ss_indoor","00:00:00")} set Lamp on;;set Rolos off

[Fonz]

Thank you!

That worked...

One more question if you its not too much trouble.

How could I then add or subtract a few minuets to this time, to get my lights exactly when I want them?

Thank you again,

Fonz

Maybe http://fhem.de/commandref.html#SUNRISE_EL is what you are looking for?

[Fonz]

Thank You Jhohn.

I was more looking to take 7 minuets away from the weather calculated Twilight time.

I find the time is very accurate, but due to a large tree my room gets dark 7 minuets before hand.

Regards,

Fonz

Did you try to tweak the indoor horizon paramater?

[Guido]

Have you already tried with the indoor_horizon ?

Twilight
Define
        define <name> Twilight <latitude> <longitude> [<indoor_horizon> [<Weather_Position>]]
Besides the location on earth it is influenced by a so called "indoor horizon" (e.g. if there are high buildings, mountains) as well as by weather conditions
The parameter indoor_horizon gives a virtual horizon higher than 0, that shall be used for calculation of indoor twilight (typical values are between 0 and 6)

in my case indoor_horizon 1 is exactly ss -7 minutes and sr +7 minutes

Sorry, double post I'm too slow

Thank you everyone.

I have fixed it with the horizon variable
