While Block execution?

#1

1) Give a description of the problem
I have provided the event log with my mark ups in yellow and text in red. The event log was cleared before a garage door contact event occurred. It seems to execute property until it reached the While block.

2) What is the expected behavior?
The code is intended to detect the garage door open, and, if so, display that event with a light attached to an outlet.
If the outlet was found to be off before the garage door was opened, it will be turned on.
If the outlet was on then it will do a 1 second flash off every 30 sec while the garage door is opened.
When the garage door closes the outlet will be returned to its original state.
At least that’s the plan .

3) What is happening/not happening?
It seems like the While block does not execute correctly

I have this log in a marked up PDF but could not see a place to attach it.

Your assistance would be welcomed.

#2

Your last statement starts with an IF and then carries on with a WHILE.
The IF and the WHILE are exactly the same statement.
I would try it without the IF and go straight to the WHILE.

#3

I will try that. Thanks

#4

I would do it like this I think.
WHILE
image
AND
image
image

I’m not 100% certain the else will run though as the WHILE will not be true and therefore no statements will run.
You might have to take the ELSE into a separate statement.

#5

I removed the If before the While and the result was the same. If I recall correctly I put the If in to see if that would fix the While issue during my many attempts earlier today.

I’ll try your last suggestion

Thanks for the help.

#6

Looking at this statement again
image
Then as soon as the outlet turns off, the while statement will become false and I don’t think the outlet will turn back on again.
Click on your DO and in the settings change the TCP (Task Cancellation Policy) to NEVER.

#7

I split the While into two parts. It is not yet happy.

Is there a better way to send the event log other than copy and paste. I looked in the SmartThing IDE and the log did not have anything in it.

Bob:

Are variables defined in a piston reset every time the piston is re-triggered? As such they can’t pass a flag parameter from piston to piston re-triggering events (as I have in my code)?

If this is the case is there a way to make them global so they will persist?

Thanks for your help.

Yes you can define global variables.
When you are editing a piston scroll down and you will see a section for global variables.
Define them there.
When you define your variable you can define an initial value. If it is left blank then whatever value it becomes will remain until it is recalculated and changes.

Thanks RE: defining global variables.

For my better understanding, do local variables in a piston get lost every time the piston exits and therefore they are not usable for passing flags to later piston events, as I was using them?

Thanks again.

Cheers,
Ray

Local variables will persist. They only differ from global variables in that local variables are only accessible in that specific piston.

Thanks for that clarification.

Hi Ray!

How did you make out with this piston? Can you share the working piston, i have need for this.

Thanks

#14

Sorry for the late response. I replied to the email version of your question but that failed to be transmitted.

Regarding the wile loop issue: I tried many things that were suggested, however, in the end, I just used a simpler method and avoided the WHILE.

Thank you for the response.
