When is the bad moon rising?

Oli · September 14, 2016, 5:00pm

Upon request,I’m trying to show the days until next full moon in a sitemap (and yes, my daughter has been watching too much Teen Wolf )
On my first try, the rule i put together resulted in massive java errors and i finally needed to shutdown&restart, so i’d like to ask y’all for some advice. What I’ve got so far:
Items:

DateTime  Naechster_Vollmond  "Nächster Vollmond [%1$td.%1$tm.%1$tY %1$tH:%1$tM]"  <death_star>    (Astro)   {astro="planet=moon, type=phase, property=full"}
Number Tage_naechster_Vollmond "Tage bis Vollmond: [%s]" <death_star>    (Astro)

Sitemap:

Text item=Naechster_Vollmond
Text item=Tage_naechster_Vollmond

da rule:

import org.openhab.core.library.types.*
import org.openhab.core.persistence.*
import org.openhab.model.script.actions.*
import java.lang.Math
import java.lang.String
import java.lang.Integer
import org.joda.time.*
import org.openhab.model.script.actions.Timer


rule "Biss zum naechsten mal"
when
    Item Naechster_Vollmond received update
then
    postUpdate(Tage_naechster_Vollmond,(Math::round((Naechster_Vollmond.calendar.millis - now.millis) / (86400000.0))))
end

Sadly, Designer is throwing errors:
Multiple markers at this line

Couldn’t resolve reference to JvmIdentifiableElement ‘/’.
Couldn’t resolve reference to JvmIdentifiableElement ‘-’.
Couldn’t resolve reference to JvmIdentifiableElement ‘millis’.
Couldn’t resolve reference to JvmIdentifiableElement ‘calendar’.
Couldn’t resolve reference to JvmIdentifiableElement ‘now’.

Does my way of calculation make sense at all? Or do I need a variable to first do the math on and then use that in postUpdate?
System info: Ubuntu 16.04 Server, OH 1.8.3, Oracle Java 1.8

Many thanks in advance,
Best Regards,

NOTE: With the latest OH 1.x Designer it has bascailly lost all knowledge of “now” so while Designer is complaining it likely really does work. At least the math looks right to me.

Oli · September 14, 2016, 5:55pm

Thanks, I kind of guessed Designer has a flaw there. Sooo…I will give it a try and report back.

Oli · September 14, 2016, 6:14pm

So I’ve uploaded the files.
Trigger Item gets refreshed:

2016-09-14 20:05:50.759 [INFO ] [runtime.busevents             ] - Naechster_Vollmond state updated to 2016-09-16T21:06:00

But the rule doesn’t get fired. I’ve added some loginfo to check that. I guess the update is comming from persistence, not the astro action. Could that be the cause? If so, would it help to issue:
openhab send Naechster_Vollmond 2016-09-16T21:06:00
fromOSGI console?

Oli · September 14, 2016, 6:47pm

OK, so I did a restart (after refreshing the sitemap, clients did not update any more - known bug AFAIK)
The rule got executed, but unfortunatly no joy:

Sep 14 20:39:53 JARVIS openhab.sh[10857]: 2016-09-14 20:39:53.873 [ERROR] [o.o.c.s.ScriptExecutionThread ] - Error during the execution of rule 'Biss zum naechsten mal': The name '<XFeatureCallImplCustom>.calendar' cannot be resolved to an item or type.

Any idea?

Edit: after following change:

(Naechster_Vollmond.state as DateTimeType).calendar.timeInMillis

even Designer doesn’t complain any more. Promising…
Too late for another openhab restart now (takes 20+ minutes and I’ve no clue why: Startup and performance issues ) so I will call it a day and check tomorrow if the Item got populated. I’ll report back…

Oli · September 15, 2016, 4:42pm

And we have a winner!
Via OSGI console, I just did a stop/restart of the astro binding and:

[runtime.busevents             ] - Naechster_Vollmond state updated to 2016-09-16T21:06:00
[hab.model.script.diverse.rules] - Berechne Tage bis Vollmond...
[runtime.busevents             ] - Tage_naechster_Vollmond state updated to 1

FyingEaglE · September 15, 2016, 10:53pm

May you give the full item-/sitemap-list, please?
where do you got the icons from?

regards & thanks

Voila:

Items:

            Text item=Jahreszeit            
        }

As for the icons- I gathered them on the Net putting them ancient hunter/collector genes to good use If you search for “icons png 32x32 iconname” you should find most of them. Even though they are all freely available for personal use, I’ll refrain from posting them here as I don’t want the Site Admins receiving letters for Copyright infringement from some cheese lawyer chasing a quick buck.

Null=unbekannt ⁉

i found this … but the upper-/lower-case is not correct …

but, how you calc the next full moon?

Oli · September 16, 2016, 5:38pm

I think the format of the map files depends on your OH version (OH1 or OH2).
For OH1, look here: https://github.com/openhab/openhab/wiki/Astro-binding
For OH2…sry, I’m out. No clue.
For full moon calculation just read Posts 1 to 5…

FyingEaglE · September 16, 2016, 7:08pm

i think it is working right now.
the dates and times for sun-/moon-rise/-set are they for the act. day or for tomorrow?
if for today, is it possible to get this for tomorrow (or more future days)?

Oli · September 16, 2016, 7:27pm

The times are calculated each midnight and are for the current day and the longitude/latidute you have in your config.
If you look at the Link to the Astro Binding, you can create Switches that get triggered with an offset in minutes from e.g. sunset. So maybe you can also create an additional DateTime Item for sunset with an offset of…ehm.hour has 60 mins…24 hours…1440 minutes to get tomorrow’s sunset, something like:

DateTime    Sonnenaufgang_Morgen_Time    "Sonnenaufgang Morgen [%1$tH:%1$tM]"       <sun>        (Astro)        { astro="planet=sun,type=rise,property=start",offset=1440}

Give it a try…worst case the Item doesn’t get updated, I guess.

FyingEaglE · September 16, 2016, 8:18pm

it seemed not be working …

it show 7:03 for sun rise but it google tells 7:04 … for tomorrow.

may be it would be calculated correctly at midnight …

Oli · September 16, 2016, 8:32pm

Well if it’s different(and later) than the value for today it should be OK. Basically the value that is now shown for tomorrow should match the “standard” sunset value you will see after recalc. I would watch this for couple days if the change pattern is right.

Udo_Hartmann · September 17, 2016, 5:26am

The offset parameter will be added to the result of calculation, so this item will show the sun rise of today (with date of tomorrow).

FyingEaglE · September 17, 2016, 6:08am

@udo, that seemed to be right.

this are the things i hate the most …

openhob.log: Could not find a mapping for ‘Aries’ in the file ‘astro_de.map’.

some post before i posted my map-file.

season is displayed well, sun’s zodiac is displayed well, phase is displayed well, but moon’s zodiac raises this error…
yesterday it worked without errors …

Oli · September 17, 2016, 9:49am

@Udo_Hartmann : thanks for clarification; it was worth a try i guess
@FyingEaglE : I would double-check that a) Item definition points to the right file b) that there is no odd typo in the file. Something like a space or other special char before or after “Aries”

FyingEaglE · September 17, 2016, 3:49pm

i can’t find any typo or special chars …

Oli · September 17, 2016, 4:20pm

So you are using one map file (astro_de.map) for all your astro items?
All other Items are “translated” OK?
Unfortunatly it’s not possible to set another Astro item to “Aries” via OSGI console(tried but they are read only) so I can’t think of another way how you could verify your entries.

FyingEaglE · September 17, 2016, 4:37pm

yes, one file for all, yesterday it worked fine.
i found out, if i write Aries=Widder, then it worked. but if i write Aries=♈ Widder (as before) it wont work.
