Rule does not fire anymore

[vaillan]

Hi guys,

i have a Problem with a rule.
It doesn´t fire anymore, and a don´t know why.

It´s quite smiple, but i am not able to get it work.

Here is my Rule:

rule "Alle Rollo rauf" 				
when
	Item Rollo_gesamt changed to 0
	
then
		
		Rollo_11.sendCommand(UP)
		Thread::sleep(2000)
		Rollo_12.sendCommand(UP)
		Thread::sleep(2000)
		Rollo_1.sendCommand(UP)
		Thread::sleep(2000)
		Rollo_2.sendCommand(UP)
		Thread::sleep(2000)
		Rollo_3.sendCommand(UP)
		Thread::sleep(2000)
		Rollo_4.sendCommand(UP)
		Thread::sleep(2000)
		Rollo_5.sendCommand(UP)
		Thread::sleep(2000)
		Rollo_6.sendCommand(UP)
		Thread::sleep(2000)
		Rollo_7.sendCommand(UP)
		Thread::sleep(2000)
		Rollo_8.sendCommand(UP)
		Thread::sleep(2000)
		Rollo_9.sendCommand(UP)
		Thread::sleep(2000)
		Rollo_10.sendCommand(UP)
		Rollo_Dummy_1.sendCommand(OFF)							  Rollo_Dummy_2.sendCommand(OFF)
		Rollo_Dummy_3.sendCommand(OFF)
		Rollo_Dummy_4.sendCommand(OFF)
		Rollo_Dummy_5.sendCommand(OFF)
		Rollo_Dummy_6.sendCommand(OFF)
		Rollo_Dummy_7.sendCommand(OFF)
		Rollo_Dummy_8.sendCommand(OFF)
		Rollo_Dummy_9.sendCommand(OFF)
		Rollo_Dummy_10.sendCommand(OFF)
		Rollo_Dummy_11.sendCommand(OFF)
		Rollo_Dummy_12.sendCommand(OFF)
		Szene_7_PM_SZ.sendCommand(7)
		Szene_9_PM_Noel.sendCommand(9)
		Szene_11_PM_Lia.sendCommand(11)
end

My Item changed to 0 but nothing happens:

2018-09-21 08:23:41.627 [ome.event.ItemCommandEvent] - Item 'Rollo_gesamt' received command 0

What could that be?

I am running on OH 2.3

The opposite rule works great:

rule "Alle Rollo runter"
when
	Item Rollo_gesamt changed to 100
then
		sendCommand(Rollo_11,DOWN)
		Thread::sleep(2000)
		sendCommand(Rollo_12,DOWN)
		Thread::sleep(2000)
		sendCommand(Rollo_1,DOWN)
		Thread::sleep(2000)
		sendCommand(Rollo_2,DOWN)
		Thread::sleep(2000)
		sendCommand(Rollo_3,DOWN)
		Thread::sleep(2000)
		sendCommand(Rollo_4,DOWN)
		Thread::sleep(2000)
		sendCommand(Rollo_5,DOWN)
		Thread::sleep(2000)
		sendCommand(Rollo_6,DOWN)
		Thread::sleep(2000)
		sendCommand(Rollo_7,DOWN)
		Thread::sleep(2000)
		sendCommand(Rollo_8,DOWN)
		Thread::sleep(2000)
		sendCommand(Rollo_9,DOWN)
		Thread::sleep(2000)
		sendCommand(Rollo_10,DOWN)
end

best regards
Vaillan

(OH 1.x and OH 2.x Rules DSL only] Why have my Rules stopped running? Why Thread::sleep is a bad idea

EDIT: While the general advice in this article still applies (i.e. it’s always worth while to make short running rules), the problem described in this article only applies to OH 1.x and Rules DSL in OH 2.x. In OH 3 and beyond, this is no longer a problem so if your rules stop running in any version of OH released in the last two years (as of this edit in 1/2023) this is not your problem. By way of explanation, in OH 3 each rule gets it’s own thread. It is no longer possible for a rule to starve…

I restart the Service, but it also didn`t work.

After i set the Rollo_gesamt Value to 100, the rule fires now, if i set the vaule to 0.

It seems that the Item Status value was broken.

But i thought that a Service restart should reset all values also.

It is working now.

But nevertheless i should rework my rules.

Thanks for help

Please keep in mind, that there is a difference between the triggers

changed and received command

changed will trigger if the state of the item is changing, or, when using changed to 0, it will trigger when the state changed from a state other than 0 to 0

received command will trigger, if the item received a command, regardless, if the state is changed or not. received command will also include the commands UP/DOWN/STOP for a rollershutter item, while the state will never change to one of those commands.
