Start a rule in a rule

[trab]

I am pritty new with openHAB so I am learning so many thx to the community otherwise I would not have started with openHAB (learningcurve)…

Could be that my solution is somewhere on the Community Blog but I did not find it. Sorry if it is.

I have made a rule that for exaple dims my bedroom lights “original rule”.
I want to use this rule in “another rule”.
Now I copy paste the “original rule” in “another rule” but if I change something in the “original rule” I have to remember to copy paste it in the “another rule”.
Is there a way to start “original rule” in “another rule”?

Many thanks

The most obvious way (for me) would be to make use of a proxy item, which changes when your original rule is running.

Ie:

rule "original rule"
When "original trigger" changed
  Then 
proxy_item.postUpdate (ON). 
....

And in your secondary rule you´ll be using:

rule "secondary rule"
When proxy_item changed
  Then 
<whatever your secondary rule is doing>
...

There may be better ways to do this. And I havn´t tested it myself. But I dont see why it shouldn´t work.

Thx Tom for your quick reaction!
But for example I use this Progressive Dimmer rule as a wake up dimmer.

Progressive Dimmer Rules

@sam2b, it may be much simpler but it is really bad practice. Your rule is holding on one of the 5 threads available You should do that with a timer: Much safer val int timeoutMills = 3 * 600 // 60000 divided by 100 dim levels var int dimLevel = 1 var Timer timer = null rule "Slowly Dim Up" when Item Outlet2_Switch changed to ON then if (timer === null) { timer = createTimer(now.plusSeconds(0), [ | //Starts immediately Light1_Dimmer.sendCommand(dimLevel) …

But I have changed/added some things (the dimLevel to 90 instead of 100).
I have made another rule to do the same when I trigger a switch.
But now I would rather have de dimLevel to 70 so I have to change it twice.
Is there a way to make a “standard rule” to dim the lights and refer to it in another rule?

to be clear I want this part as the standard rule

if (timer === null) {
    timer = createTimer(now.plusSeconds(0), [ |   //Starts immediately
        Light1_Dimmer.sendCommand(dimLevel)
        if (dimLevel == 100) {
            timer = null // cancel timer
        } else {
            dimLevel = dimLevel + 1
            timer.reschedule(now.plusMillis(timeoutMills)) // reschedule timer is 3 * 600 mills
        }
    ])
}

Reusable Functions: A simple lambda example with copious notes

Major Edit: Rewrote with the cleaner OH 2.3 syntax. The example lambda on the OH 1 wiki is overly complex and as written will not work in OH 2. This quick example will show a super simple lambda example with copious notes. Here is the code without comments. It takes in an Item, logs it’s state and returns a slightly modified version of the String logged. val log= [ GenericItem s | logInfo("lambda", s.state.toString) s.state.toString + " logged" ] rule "Call Lambda" when // some t…

There are several approaches. Which one is best depends on the context.

• Scripts: A simple scene management: finally a good use of scripts

• Separate Rule: Design Pattern: Separation of Behaviors (this is Kim’s suggestion)

• Lambdas: Reusable Functions: A simple lambda example with copious notes (rossko57’s suggestion)

How about group your items and use the “Member of” trigger?
Within the rule refer to triggeringItem.

[5iver (Scott Rushworth)]

The new rule engine allows for you to execute a rule’s action from another rule’s action. This can be done in rules created through the UI or scripted automation. Actually, you can create just actions without triggers, so not a full rule, and execute those from rules.

thx all, still figuring out what to use for what…
