[Solved] When sunrise then...
@andre3000 said in [Solved] When sunrise then...:
When the sun goes down in Vietnam (~6 p.m) it´s 00:06 a.m next day in Germany. <- I think this is the issue because Pimatic and the variable do not recognize that the date changed to the next day.
Exactly this is the case. Before sunrise only works from 00:00 until sunrise and after sunset only works from sunset until 23:59.
Why don’t you change the locale or the time of your Raspi? Then you don’t need to calculate around.

You mean changing back to Germany? If I would do this, then the sunrise and sunset time would´t be displayed correctly.
It would be easier to calculate but it wont look good enough. I have to mention, that I will use a 5" display above the terrarium to show all the actual informations like sunrise,sunset, temp in vietnam, temp in terrarium usw.
Do you have any idea how to change the timezone in sunrise plugin without having to change raspi location?
BR,
André
I mean configuring the pi like it is located in Vietnam. Locale and timezone. Then you don’t need to calculate anything and sunset/sunrise will always match the Vietnam time.
And thats what I mean why it´s so difficult to explain :D
My raspi is actually set up like its located in Vietnam. But in Vietnam its now 7 p.m -> If I would not calculate the offset then the lights would already be turned off. -> But thats not what I want. It´s 1 p.m German Time… all the lights should be turned on.

If I got this right, you want to simulate the hours of daylight in Vietnam, but you want use that at our local daylight time. I think that tricky. My first thoughts on this:
You need to calculate the number of daylight hours, minutes in Vietnam. Then you can switch as follows, for example:
Unfortunately, the device type provided with pimatic-sunrise does not provide for daylight hours and thus you need to calculate it yourself.

You go it it mate! That´s exactly what I want to do! 
Any suggestions where I have to look for a possible solution? I´m an absolute beginner but always trying my best to figure it out by my own.

Is it not enough to set the sunrise plugin to Vietnam and use the local time?

If you tell my how to do this? I haven´t found any option to change the timezone directly in the plugin.
Im not quite sure but it feels like pimatic is getting the time from the system time.
@andre3000 Rather than just using the builtin events which are tied to the timezone set on the operating system, You can create a SunriseDevice with the geo coordinates in question. Additionally make sure to configure sunset and sunrise attributes on the device as part of the devise configuration. Say, you device is called “vietnam” you should be able to use “vietnam.sunrise” and “vietnam.sunset” as part of rules. It is still somewhat tricky to calculate the daylight hours, minutes. I may come back to you later with a proposal

Thats what i mean!
Here is the code for the device configuration according to https://github.com/pimatic/pimatic-sunrise
{
"id": "sunrise-1",
"class": "SunriseDevice",
"name": "Sunrise",
"latitude": 52.5072111,
"longitude": 13.1449592,
"attributes": [
{
"name": "sunrise vietnam",
"label": "Sunrise Time Vietnam"
},
{
"name": "sunset vietnam",
"label": "Sunset Time Vietnam"
}
]
}

This would be great. Thanks to all repliers for your outstanding support and willingness to help

Actually, it is not tied to local time of the OS, but to the geo coordinates in the plugin configuration. Sorry for the confusion. So, use you local geo coordinate in the plugin configuration, and setup a device with Vietnam geo coords

@flop2006
Your Coordinates are in Germany?! Why don´t you use the coordinates in Vietnam?
If i unstood you correctly, I should configure the plugin with german location and the device with vietnam location?
Is that right?

@mwittig Thanks! Now I managed to set the german location in my raspi config and still see the Vietnam time zone in Pimatic! Thats a great step forward.
Sorry, I have to revise my reply! The plugin shows now the german sunrise time.
EDIT: I reloaded everything and now it looks like this:
Sunrise Vietnam and Sunset Vietnam are set correctly but in German time
@andre3000 That’s great.
Note, daylight hours in Ho Chi Minh vary only between 11:30 and 12:45 hours throughout the year. Does one hour 15 minutes already make a big difference for the given habitat? Wouldn’t it be simpler to use an average of 12 hours a day?

It was my own goal to imitate the natural habitat of my turtle as closely as possible and the daylight is an important part of it. If it is not possible to reach my target with a reasonable effort, I would have to rethink my setup.
Are there any other ideas we could try?
Just a quick summary:
LED-Stripe has to be turned on between sunrise and sunset
Tageslicht has to be turned on 2h after sunrise and turned off 2h before sunset
Spot has to be turned on 5h after sunrise and turned off 4h before sunset
Sunset and Sunrise time has to be displayed correctly.
I appreciate any help.
Best regards,
André
I think its a bit late but sorry for my English

No worries. I was just wondering.
I have no experience with reptiles at all
Please try the following. It’s perhaps not perfect, but it should work under the assumption that the local sunrise time plus Ho Chi Minh daylight hours offset is before midnight local time. This is the case for Germany, at least.
Setup two SunriseDevices, one with the coords for Ho Chi Minh and one with the coords for your home town. I have named these devices “vietnam” and “local” in my example. Please change names to what you prefer. Now you can do the following to switch off the light.
WHEN its "{timeFormat(timeDecimal($local.sunrise) + timeDecimal($vietnam.sunset) - timeDecimal($vietnam.sunrise))}"
THEN turn tageslicht off
EDIT: My assumption is that it is OK to switch on the light at “local.sunrise” and let the artificial day last for Vietnam daylight hours. Hence switching on the light is as follows:
WHEN its sunrise
THEN turn tageslicht on
If you prefer to have a variable for the switch off time you’ll need a rule to update it as variable are not updated automatically per se.
WHEN its sunrise
THEN set $sunDown to "{timeFormat(timeDecimal($local.sunrise) + timeDecimal($vietnam.sunset) - timeDecimal($vietnam.sunrise))}"
