Randomized Lighting - two questions re Cancel Jobs and Randomization code

OldPro · 2020-03-01 06:42:36 UTC

See attached green Piston for randomizing lights when we are on Vacation or Away from the house:

When I arrive home and change Mode from Vacation to Home, the lights keep going on and off. Should this Piston cancel pending jobs when we come home and I set Mode = Home? If yes, what code do I use to determine the Mode has changed to Home and how do I cancel pending jobs?
You will see multiple IF/THENs to randomize seven lights. The first of the seven lights (IF #21) seems to get executed more than the others. With the logic shown, will all seven IFs be executed about the same number of times (depends on how “random” evaluates, of course). Do ALL the IFs (21, 24, 29, 36, 41, 59, 67) get evaluated on every pass through async IF / THEN and each get a unique value of Random? If more than one of the IFs evaluate to true, do multiple jobs get scheduled? Or, if IF #21 evaluates to TRUE, do the succeeding IFs not get evaluated?

Quick answer:

I would change your “Only When” into an IF…

orangebucket · 2020-03-01 08:54:21 UTC

My understanding is that the ‘only when’ at the start of your piston restricts whether the ‘every 30 minutes’ cycle gets started when the piston is resumed. I don’t think it gets reassessed. It won’t apply to what it going on inside the ‘every’ block.

There is a command for cancelling scheduled tasks. I don’t know if it will stop the ‘every’ timer.

I’m not sure what the ‘async’ on the ‘if’ is acheiving but I’d imagine it is harmless. It looks like all those 'if’s should run in sequence every time. I guess a lot depends on how the random numbers work and how the sequence start point is randomised.

WC – stupid question, but I cannot find a simple way to do that. I struggle with this all the time in webCoRE.

WCmore · 2020-03-01 18:43:53 UTC

There is no such thing as a stupid question…

Instead of the piston starting off like this:

ONLY WHEN
    Location mode is any of Vacation or Home
Every 30 minutes
    do Stuff
END EVERY

My recommendation would be something like this:

Every 30 minutes
do
    IF Location mode is any of Vacation or Home
        Then do Stuff
    END IF
END EVERY

With this second variation, the block will cancel out if Location is no longer Vacation or Home

Thanks. My question was more about the mechanics of using the webCoRE environment for programming. We obviously cannot write code (for understandable reasons). I have a very hard time in the webCoRE environment modifying code to make the changes you suggested. I click on some lines and nothing happens. I find a statement farther down in the block can make changes. The drag and drop is very iffy and has a tendency to mess things up. You cannot copy/paste blocks of code.

How do you maintain code and make changes such as the one you suggest?

WCmore · 2020-03-01 20:07:45 UTC

Oh, we can definitely do this!!

Here is my tips for moving/copying/pasting code.
(It works like a champ if you drop in the right spot)

If you need to copy in the same piston, hold CTRL while dragging. If you want to copy a block of code to another piston, then the link above goes into more detail.

WCmore · 2020-03-01 23:12:36 UTC

My apologies.
The drag & drop method cannot delete “Only When”, nor can it create a new “IF” block from nothing.

(Creation & deletion must be done manually. Let us know if you need help with this)

but… the good news is, once your new IF block is created, you can drag and drop it to the right spot in the code. Then, you can (carefully) drag the old code into the new structure. (Working on a large monitor helps with this)

This saves you from retyping it all out again.

Edit:

This conversation inspired me to add new tips to the Wiki
