Hi All, Need help with a rule. The rule below dictates the state of the house. Problem is that occasionally when I press the ‘Wake Up’ command openhab sends the ‘Go to Bed’ command. This has happened using the mobile app and Habpanel. The strange thing is that this rule works 90% of the time. The p…

rule "House Scene Activity" when Item Scene_TV changed then Thread::sleep(x) ... test what is the necessary time on you system.

This issue occurs because you are checking the state of Scene_TV BEFORE it has actually updated after receiving a command. It can take a few milliseconds and by that time your rule is already running. Change the case statements with the implicit variable receivedCommand should get rid of the proble…

I will give this a try. Thanks for your help.

@vzorglub , I got a question here, should it not be: switch sceneNumber // instead of Scene_TV { case 1 : //watching tv ... case 2 : //going to bed // ... and so on ... since you said that Scene_TV might take some time to update?

Yes, you are right I replied too quickly. The important bit is the delay between the command received and item being updated. Did you understant that and does it make sense. It’s important because it can cause unpredictable behaviour (As in your case) and therefore you need to choose carefully wh…

Thanks @vzorglub for the clarification! I think I do understand; I see the “implicit” as a the “variable” that is passed on to the rule being called (and then start executing), while in a parallel process (asynchronous to the rule execution) the item is updated. Since this is asynchronous, the item…

Is it this issue? Mysterious delay in items being updated

If so, you can fix it with a Thread::sleep(500) at the start of the rule
