OH3: Scripts do not work

[rossko57]

The new rules engine allows triggers with “but only” conditions …
But it is still important to understand that the primary trigger is an event, not a condition.

You cannot trigger on item = x, it’s just not an event. Item changing to x is an event.

Previously, we might trigger a rule by door opening, then in the body of the rule test if was dark before turning on the light.

Now we have a little shorthand, we can trigger on door-opening BUT ONLY IF state = dark.
It’s the same event driven structure.

[Dejan]

I understand that trigger is event. Im try right now my way and looks like with ay which Im describe in second question in last post Im get what I need.
Im create Rule with ItemStateChangeTrigger on one test item without previous state and state value. Im as Then action set to run ECMAScript and in script do small demo example:

var logger = Java.type(“org.slf4j.LoggerFactory”).getLogger(“org.openhab.core.model.script.LowBatteryTrigger”);
logger.debug(“Trigger Started”);
var from = parseFloat(oldState.toString().split(’ ‘)[0]);
var to = parseFloat(newState.toString().split(’ ')[0]);
logger.debug("From: " + from);
logger.debug("To: " + to);
if (from <= 50 && to >= 51) {
events.sendCommand(‘ZWave_Floor1_Office_Dimmer_TableLight_Dimmer’, ‘0’);
logger.debug(“Triger OK”);
}
logger.debug(“Trigger Finished”);

18:00:11.572 [DEBUG] [b.core.model.script.LowBatteryTrigger] - Trigger Started
18:00:11.623 [DEBUG] [b.core.model.script.LowBatteryTrigger] - From: 0
18:00:11.627 [DEBUG] [b.core.model.script.LowBatteryTrigger] - To: 100
18:00:11.669 [DEBUG] [b.core.model.script.LowBatteryTrigger] - Triger OK
18:00:11.673 [DEBUG] [b.core.model.script.LowBatteryTrigger] - Trigger Finished
18:00:11.720 [DEBUG] [b.core.model.script.LowBatteryTrigger] - Trigger Started
18:00:11.739 [DEBUG] [b.core.model.script.LowBatteryTrigger] - From: 100
18:00:11.743 [DEBUG] [b.core.model.script.LowBatteryTrigger] - To: 0
18:00:11.746 [DEBUG] [b.core.model.script.LowBatteryTrigger] - Trigger Finished

By quick test it work as must. When I turn on test dimmer it meet requirements and turn it off… That way I can make script for Low Battery event…

@Dejan

1.) What about “But only if” what is here used OR or AND? Because there usually we will need both options… We can do something if (item1 = 0 AND item2 = 0) or we can do something if (item1 = 0 OR item2=0) …

You can define the conditional how ever you want. If the UI doesn’t support what you want you can even write your own script to handle the condition. For HestiaPi I even put corrective actions into the condition. For example, if one ties to set an Item to a state that isn’t allowed, it prevents the rule from running and resets the Item back to it’s previous state

But as rossko57 says, the rule triggers on events. Once triggered you can check the states of Items and time and anything else relevant to see if the rule needs to run or not.

@Dejan

2.) If Im understand right I will need to make triger which triget on every “ZWave_Floor2_Kitchen_Thermostat_BatteryLevel” state change and run as action(Then) script in which I will check state of item and action which I would like to do?

That’s one way to do it. But what I’ve been describing is you trigger the rule for all state changes to that Item. The conditional checks to see if the Item has changed from and to a state where an alert is required. Only if that evaluates to true does the action run where the alert is sent.

@Dejan

Which scripting language is preffered to use in long term support or offer more options “Rule DSL (v1)” or “ECMAScript (ECMA - 262 Edition 5.1)” ? So I don’t want spend learning one of them because is added as legacy support and ill be terminated in some next versions…

I think it’s safe to use either. I don’t see either going anywhere any time soon. There are more examples of Rules DSL on the forum and the docs. But ECMA (i.e. JavaScript), being a popular language outside of openHAB, will have more resources in the wider world to help you learn it. Groovy is also an option (install-able as an addon in OH 3 M2) and Python will become available someday.

@Dejan

Is in OH3 option to make triggers outside GUI?

I don’t know what this means. If you mean you want to write rules without using MainUI than yes, you can write rules outside of the GUI just like you can do any other configuration outside of the GUI.

[Dejan]

Is there some documentation/references what “modules”, “classes” are availible in scripting and how to use it?
I can’t find anything usefull and Im new at openhab “ECMA scripting” Im develop apps in Delphi, Java, C#.

Im sucessfully add loging option in script:

var logger = Java.type(“org.slf4j.LoggerFactory”).getLogger(“org.openhab.core.model.script.LowBatteryTrigger”);
logger.debug(“DEMO Log”);

Now I would like to know how can I use external actions for example send Push notification trough OpenHAB Cloud addon…
Im try add it like:

var push_notification = Java.type(“org.eclipse.smarthome.io.openhabcloud.internal.CloudService”);

or

var push_notification = Java.type(“io.openhabcloud.internal.CloudService”);

But it crash at that line…

[Dejan]

I still cant get simple sendNotification() to work… All time I get “java.lang.ClassNotFoundException” errors…
Im try several way to use openhab cloud sendnotification function like:

var openhab_notification = Java.type(“org.openhab.io.openhabcloud.NotificationAction”);
openhab_notification.sendNotification(“email”, “This is notification”);

var openhab_notification = org.openhab.io.openhabcloud.NotificationAction;
openhab_notification.sendNotification(“email”, “This is notification”);

How we can send notification in OH3?

[rlkoshak (Rich Koshak)]

@Dejan

Is there some documentation/references what “modules”, “classes” are availible in scripting and how to use it?

I strongly encourage the use of the Helper Libraries. They are documented at Helper Libraries for openHAB Scripted Automation — openHAB Helper Libraries documentation. In particular pay attention to the “But how do I…” page. Also look at the library source code which is informative.

I’ve posted some further examples at openHAB 3.0 my getting started notes: Rules (I return and update this periodically so check back often) and much older examples at Experimental Next-Gen Rules Engine Documentation 1 of : Introduction which have a lot of stuff that is no longer correct but is still largely useful. Full docs for ECMA Script have not been built yet.

I’ve not tried to send a notification yet so I cannot say for sure. But org.openhab.io.openhabCloud.NotificationAction is the correct path according to the code on github.

[Dejan]

Hi,
Im already try helper libraries with javascript but didn’t work. I will try them again with carefully reading instructions…
As Im try a lot of things I can’t find way to run anything usefull from scripts… Everything fail with ClassNotFoundException …

[rlkoshak (Rich Koshak)]

@Dejan

Im already try helper libraries with javascript but didn’t work.

What didn’t work?

Also, did you install the openHAB Cloud Connector add-on?

I don’t have the cloud connector installed in OH3 so I can’t test it myself at this time because one can only have one OH instance connected to the myopenhab.org server at a time.

[Dejan]

Nothing didn’t work
Now Im do everything as written in tutorial but they do not work also HelloWorld.js do not write into log every 10 seconds…
First Im enable logging:
jsr223 │ DEBUG
org.openhab.core.automation │ DEBUG

Then Im shutdown openhab and copy files.

Im copy content of Core folder into openhab:

Then Im rename configuration file:

And copy demo script to personal folder:

Then Im start openhab and log:tail

19:16:24.465 [DEBUG] [re.automation.internal.RuleEngineImpl] - The rule '71a2abce18' is executed.

This is my developing Windows 10 computer but same happen on linux openhab server…

Im try sendNotification with official 3.0.0M2(Installed from UI) and 3.0.0.SNAPSHOT(Installed manualy) on linux server and on windows pc and it crash wirh ClassNotFoundException …

Im also myself modify and build openhabcloud addon from sources and make it simple for debuging only and make it by new RuleAction way like in Mail or other addons but still didn’t work…

@Dejan

It still crash:

Hmmm, I thought there was an update to the libraries for that. The LogAction changed names to Log. You can get past this error by editing actions.js and change LogAction to Log.

Does the notify action work if you write a Script Action using Rule DSL? I think sending a notification should be one of the options for choosing an Action for the rule which would not involve writing any code. Is it there? Does it work when you select it?

There is nothing to type or import and the like to use it in Rules DSL. If it doesn’t even work there then something else outside of the rules is the source of the problem.

[Dejan]

Im on middle updating windows openhab server to latest snapshot to test if there has been some problem with M1 and M2 version and ECMA scripts and already fixed…
Im try Rule DSL on my linux openhab server and it work.

Sending script:

sendNotification("EMAIL", "This is a directed notification");

Log:

2020-11-09 18:48:46.939 [DEBUG] [b.io.openhabcloud.NotificationAction] - sending notification 'This is a directed notification' to user EMAIL
2020-11-09 18:48:46.940 [DEBUG] [o.openhabcloud.internal.CloudService] - Sending message 'This is a directed notification' to user id EMAIL

Script run normaly and I receive notification on mobile phone…

[rlkoshak (Rich Koshak)]

All I can offer at this point is at one point years ago when I started experimenting with the NGRE (which is what this is) I got the notifications working using

var NotificationAction = org.openhab.io.openhabcloud.NotificationAction;
NotificationAction.sendNotification("rlkoshak@gmail.com", "This is a directed notification");
NotificationAction.sendNotification("rlkoshak@gmail.com", "This is a detailed directed notification", "light", "WARN"); // TODO what is severity? "light" is the icon
NotificationAction.sendBroadcastNotification("This is a broadcast test");
NotificationAction.sendBroadcastNotification("This is a detailed brodcast test", "light", "WARN")
NotificationAction.sendLogNotification("This is a log notification");
NotificationAction.sendLogNotification("This is a detailed log notification", "light", "WARN");

[Dejan]

Yes there is something wrong with NGRE engine on OH3 …
For me doesn’t work your way:

var logger = Java.type("org.slf4j.LoggerFactory").getLogger("org.openhab.core.model.script.LowBatteryTrigger");
logger.debug("Trigger Started");
var NotificationAction = org.openhab.io.openhabcloud.NotificationAction;
if (NotificationAction == null)
  {
      logger.debug("NULL");
  }
else
  {
      NotificationAction.sendNotification("EMAIL", "This is a directed notification");
      logger.debug("SEND");
  }
logger.debug("Trigger Finished");

So NotificationAction is not null but it still crash:

Same thing happen when I test on 3.0.0-SNAPSHOT - Build #2006 on Windows PC… DSL work ECMA not.
Im found in source codes that cloud plugin need dependenncy org.apache.servicemix.bundles.jsr305 if that mean something(DSL or ECMA) …

[rlkoshak (Rich Koshak)]

@Dejan

So NotificationAction is not null but it still crash:

In JavaScript you would want to test for undefined.

if(NotificationAction === undefined)

@Dejan

Im found in source codes that cloud plugin need dependenncy org.apache.servicemix.bundles.jsr305 if that mean something(DSL or ECMA) …

It doesn’t.

[Dejan]

Im get it working on both DSL and ECMA scripts. For some strange reason after installation of openhab cloud addon openhab server MUST be restarted otherwise sendNotification do not work in ECMA and function is visible on DSL but do not send anything and in log write “No connection, notification is not sent” but cloud connection work normaly and over wan I normaly see sitemaps…
So only script access didn’t work until restart after addon installation… Im test this few times and can confirm that this can be reproduced… Because Im develop openhab addon on my computer and add access to rest api with token authentication it didn’t work because Im rebuild&install addon without openhab restart and push messages never didn’t work.
Now Im make ECMA Rule script which ill send push message when battery will be under 30% and send push notification when it will be full(99% or 100%)… Last two messages are how they will look and older are test messages before removing some parts of item name…

Did you create the rule before or after installing the addon? I ask because the first time the rule is run it is given a context and each subsequent run it gets the same context. This is a good thing as it gives us a place (at least in ECMAScript) to store data from one run to the next of the rule. But this context likely does not get updated when new Actions are installed. If this is in fact what happened, it might be enough to just open the rule for editing and make some minor change (e.g. add a space) and save it. You may not even need to make a change, just re-save it. That will recreate the rule and therefore recreate the context with the new addon now being available. You can see the rule being recreated in events.log.

[Dejan]

Im not sure and can’t confirm or deny… But if remember right cloud addon has been installed because Im also create few new scripts… But Im sure edit, make changes and save rule when plugin has been already installed…

[binderth (Thomas Binder)]

@rlkoshak

NotificationAction.sendNotification("rlkoshak@gmail.com", "This is a detailed directed notification", "light", "WARN"); // TODO what is severity? "light" is the icon

Thanks Rich for that. I was looking all over the place for a way to use sendNotification in ECMA.
Did you - or anyone - find out, what kind of severity there is?

sorry @rlkoshak

…and sorry @rlkoshak, if I just sent you a notification, I copied your code and due to a crash in the OH3-GUI I had to re-copy it and forgot to change your email to mine…

[binderth (Thomas Binder)]

@binderth

Did you - or anyone - find out, what kind of severity there is?

I want to solve!!!
it’s the names of the icons: Icons | openHAB

[Dejan]

Yes icon name and it will show you different icons…
