Rollershuter rules; Error: Ambiguous methods

Bueddy · February 21, 2017, 12:52pm

Dear all,

I am trying to configure my roller shutters in OpenHab1. Due to the testing, based on manual switches.
As I am not so skilled in defining the rules, I am working in an agile fashion, starting with very simple functionality, which is up and down based on sunset and sunrise, an override/disable function and implement different scopes for weekdays and weekends, later incl. public holidays. Movement only in a certain time window, like between 7 and 11pm will implemented later. Additionally, I am looking for a solution, to move each shutter with a random delay, where the order is allowd to change. Maybe someone can advise how to achieve this too and if this approach makes sense or not.

Currently I am struggling with the override, which is a switch, to disable the rules.
If this rule runs incl. the override switch:

rule "Rollos Hoch"
when 
        Item Event_Sonnenaufgang1 received update ON
then
		if(now.getDayOfWeek <= 5) //&& // Montag bis Freitag
		if(HM_Fenster_Automodus.state != OFF){
			HM_Fenster_Arbeitszimmer.sendCommand(UP)
		}
end

I got this this error:

I have no clue, what this error should tell me?! If I remove the override clause “HM_Fenster_Automodus.state” everything is fine.

Thanks and regards
Manuel

You are missing the curl brackets {} around the second if clause.

Hi opus,

thanks, now it is working.
Was of the view the && will do it, but will only work within one if clause.

Regards
