Timers firing behaviour

[rbonvino (Raffaello Bonvino)]

Hi all, I have the following rule for my irrigation system:

    rule "Irrigation run"
    when
        Time cron "0 0 0 * * ?" or
		Item IrrigationTimeHour changed	or
		Item IrrigationTimeMinutes changed	
    then

				var minute = IrrigationTimeMinutes.state as DecimalType

				// Combine the hour and minutes to one string to be displayed in the 
				// user interface
				if ((hour as Number) < 10) { msg = "0" } 
				msg = msg + IrrigationTimeHour.state.format("%d") + ":"

				if ((minute as Number) < 10) { msg = msg + "0" }
				msg = msg + IrrigationTimeMinutes.state.format("%d")

I found that the timers I have fire either when they’re created and when they expire. I just want that they fire when they expire. Can you help me? Thanks in advance and merry Christmas to all!!!

@rbonvino

if(Timer1start!=null)

I did not get into the problem, but I caught my eye:

if(Timer1start!==null)

[rbonvino (Raffaello Bonvino)]

if(Timer1start!==null)

Never seen that beefore…

[Olymp (Sergey M)]

@rbonvino

Never seen that beefore…

Did it help you?

[rbonvino (Raffaello Bonvino)]

Not tried yet, but previously had not that statements with the same result… I’ll give it a try…

[rbonvino (Raffaello Bonvino)]

@Olymp

Did it help you?

Tried it, but always the same result…

[Udo_Hartmann]

As a matter of fact, a timer can’t fire twice, but it’s likely that a timer maybe would fire immediately if set to a datetime which has passed right now. (as you calculate the time always with 00 as seconds…)

The difference between != and !== is explained here by @rlkoshak : Trrying to turn a device off after a certain amount of time
You do not need to use this, as it should only create a warn in your logs for now, and you should only use it when comparing to null (yes, there is a difference, but it should not interfere here).

I think you should try to simplify the rule. For example:

if(Timer1start!=null)
    {
        Timer1start.cancel()	
        Timer1start = null
    }

As you set Timer1start (and every other timer) right after killing an old one, there is no need to set the var to null, so you can just use

if (Timer1start !== null) Timer1start.cancel

In question of this part:

if ((Irrigation_Master.state == ON) &&
  (((day == 1) && (IrrigationMonday.state == ON)) ||
   ((day == 2) && (IrrigationTuesday.state == ON)) ||
   ((day == 3) && (IrrigationWensday.state == ON)) ||
   ((day == 4) && (IrrigationThursday.state == ON)) ||
   ((day == 5) && (IrrigationFriday.state == ON)) ||
   ((day == 6) && (IrrigationSaturday.state == ON)) ||
   ((day == 7) && (IrrigationSunday.state == ON))))

I would use another rule and an additional item:

Switch IrrigationDo

rule "set IrrigationDo"
when
    Time cron "1 0 0 * * ?" or
    Item Irrigation_Master changed or
    Item IrrigationMonday changed or
    Item IrrigationTuesday changed or
    Item IrrigationWednesday changed or
    Item IrrigationThursday changed or
    Item IrrigationFriday changed or
    Item IrrigationSaturday changed or
    Item IrrigationSunday changed
then
    val day = now.getDayOfWeek()
    IrrigationDo.postUpdate(
    if (Irrigation_Master.state == ON && (
      (day == 1 && IrrigationMonday.state == ON) ||
      (day == 2 && IrrigationTuesday.state == ON) ||
      (day == 3 && IrrigationWensday.state == ON) ||
      (day == 4 && IrrigationThursday.state == ON) ||
      (day == 5 && IrrigationFriday.state == ON) ||
      (day == 6 && IrrigationSaturday.state == ON) ||
      (day == 7 && IrrigationSunday.state == ON) ) )
        ON else OFF)
end

Keep in mind that you could use a way more elegant way to solve this if using a group and other names for the Irrigation items (Irrigation_1 to Irrigation_7, IrrigationDays would be a group with all Irrigation_n Items as members):

if (Irrigation_Master.state == ON)
    IrrigationDays.filter(Day|
        Day.name.contains(now.getDayOfWeek.toString)
    ).first(today|
        IrrigationDo.postUpdate(today.state)
    )
else
    IrrigationDo.postUpdate(OFF)

then you only have to use

if (IrrigationDo.state == ON) 

in all timers. Of course you should ensure this rule is executed before the other one (set the Seconds a bit higher)

Thank you Udo, my fault. I was not understanding that I was setting a timer (at 02.00 am) that had to fire the next day, but also was expired in the same day (i was setting it after 02.00 am). I modified the rules in the following way:
