System Start Level changed

Setup, Configuration and Use Scripts & Rules

Is there a way of using System Start Level with an implicite variable like we do with newState?
Something like this:

when
   SystemStartLevel changed
then
   switch newState {
      case 40:
      case 60:
      case 80:
      case 100:
  }

some times ago i realized it with an item:

Number		StartLevel 							"Start Level"

and this rule:

rule StartLevel40
when
	System reached start level 40
then
	logWarn("StartLevel40", "Rule for Event <System reached start level 40> started")
	StartLevel.postUpdate(40)
end

rule StartLevel50
when
	System reached start level 50
then
	logWarn("StartLevel50", "Rule for Event <System reached start level 50> started")
	if (StartLevel.state < 50)	{ StartLevel.postUpdate(50) }
	else { logWarn("StartLevel50", "StartLevel decreased from " + StartLevel.state + " to 50") }
end

rule StartLevel70
when
	System reached start level 70
then
	logWarn("StartLevel70", "Rule for Event <System reached start level 70> started")
	if (StartLevel.state < 70)	{ StartLevel.postUpdate(70) }
	else { logWarn("StartLevel70", "StartLevel decreased from " + StartLevel.state + " to 70") }
end

rule StartLevel80
when
	System reached start level 80
then
	logWarn("StartLevel80", "Rule for Event <System reached start level 80> started")
	if (StartLevel.state < 80)	{ StartLevel.postUpdate(80) }
	else { logWarn("StartLevel80", "StartLevel decreased from " + StartLevel.state + " to 80") }
end

rule StartLevel100
when
	System reached start level 100
then
	logWarn("StartLevel100", "Rule for Event <System reached start level 100> started")
	if (StartLevel.state < 100)	{ StartLevel.postUpdate(100) }
	else { logWarn("StartLevel100", "StartLevel decreased from " + StartLevel.state + " to 100") }
end

i think there could be more elegant way to do this but for me it worked :slightly_smiling_face:

This is exactly how I do it today and I am looking for a more elegant way so that I can manage all my System Start actions in one rule :slight_smile:

Just for completeness, actually there IS an implicit variable available, guess who :slight_smile: ,

startlevel

so that you can manage your startup from one rule

configuration: {}

  - id: "1"
    configuration:
      startlevel: 20
