Astro Binding fires set#event too early

Setup, Configuration and Use Scripts & Rules

I noticed that my rullershooter closes to earlier.
I use a rule to close the rollershutter, triggered by astro:sun:home:set#event.

Astro binding is configured by a .thing file. The channel rise has an earliest attribute set to 18:00.
I see 18:00 as schedule time in UI item’s view - so configuration seems to be good.

What I can think of is that maybe the offset=0 causes troubles? But the UI configuration also show this value, at least inside the UI.

I also checked the server’s time and timezone and I had set the correct timezone. But as the shutter closes at 15:23 (see logfile below), the timezone seems to be not the issue. The time itself is correct - does openHAB run some other time internally?

My understand about the astro binding and its channels is as follows:
The set#event has a START and a END trigger. The offset shifts these events either into future (negative) or to past where as Earliest and Latest set a hard-defined time.

astro.things:

astro:sun:home  [ geolocation="<removed>,<removed>,<removed>", interval=60 ] {
    Channels:
        Type rangeEvent : rise#event [
            offset=0
        ]

// this is not a trigger channel configuration!
        Type start : set#start [
            offset=0,
            earliest="18:00",
            latest="20:00"
        ]

astro.items

DateTime        Sunset_Time "Sunset [%1$tH:%1$tM]"      { channel="astro:sun:home:set#start" }

astro.rules:

rule "Sonnenuntergangs_Routinen"
when
    Channel "astro:sun:home:set#event" triggered START
then
    val telegramAction = getActions("telegram","telegram:telegramBot:071d582f96")
    telegramAction.sendTelegram("(I) Routine: Sonnenuntergang")
    logInfo("astro","Sonnenuntergangs-Routine gestartet")

    // Rollladen schließen
    RademacherBridge_RolleFenster.sendCommand(50)
end

openhab.log:

2022-02-18 15:23:59.710 [INFO ] [org.openhab.core.model.script.astro ] - Sonnenuntergangs-Routine gestartet

Solution

Thanks to the posts of Wolfgang_S and rossko57 I was able to correct my code and understand the astro binding better. But first things first…

The trigger channels are defined with:

Type rangeEvent : <trg_ch>#event []

My described understanding was not completely wrong, the basics are correct but what I didn’t know is that the binding comes with:

  • common channels, that can be linked to items, and
  • trigger channels that behave as described in the posted article of rossko57

Beside their naming, they have nothing in common.

Thanks for any idea, help or solution :checkered_flag:

Shouldn’t it be

Type rangeEvent : set#event [

instead of

You should review

You have not set the trigger channel earliest/latest.
