[SOLVED] ERROR: JSR223 Javascript - How to get state?

HFM · January 21, 2018, 5:46pm

Hi,

I have installed the experimental rules on my RPI3 with openhabian and put the files from the mini-wiki (jslib) in /srv/openhab2-conf/automation/jsr223.

Then I changed paths in JSRule.js and helper.js. Next I generated in the same dir a file called test.js.

'use strict';

load('/srv/openhab2-conf/automation/jsr223/jslib/JSRule.js'); 

logInfo("################# SimpleRuleExamples.js ##################", TimerTrigger);

JSRule({
name: "Example 4",
description: "Most simple spelling live",
triggers: [ //Enable/Disable Rule
	//NOT Working: ShutDown()
	//NOT Working: StartupTrigger()
	//stateCondition("testItemSwitch", "ON", "cond1") //Error: Can not create new object with constructor org.eclipse.smarthome.automation.Condition with the passed arguments; they do not match any of its method signatures.
	//IS WORKING: TimerTrigger("0/15 * * * * ?")
	//IS WORKING: new TimerTrigger("0/15 * * * * ?")
	//TimerTrigger("0/15 * * * * ?")
	//StartupTrigger()
	//IS WORKING: ChangedEventTrigger("testItemSwitch", "ON", "OFF")
	//IS WORKING: UpdatedEventTrigger("testItemSwitch"),
    //IS WORKING: CommandEventTrigger("testItemSwitch")
    //CommandEventTrigger("Test_Button", "ON", "OFF") 
    CommandEventTrigger("Test_Button") 
],
execute: function( module, input){
    
    sendCommand("Wallplugs_i2", ON);
    logInfo("Wallplugs_i2 "+__LINE__, "Wallplugs_i2.state = " + Wallplugs_i2.state);

} 
});

The sendCommand works, but I cannot get the state. If I try I get the following error:
2018-01-21 18:44:57.467 [ERROR] [.automation.core.internal.RuleEngine] - Failed to execute rule ‘a35b4ab9-ab50-4d97-819c-1578a9642d98’: Fail to execute action: 1

I took the file from github (example 4):

github.com

lewie/openhab2-javascript/blob/master/SimpleRuleExamples.js

'use strict';

load('./../conf/automation/jsr223/jslib/JSRule.js');

logInfo("################# SimpleRuleExamples.js ##################", TimerTrigger);

//### Example 1: Default spelling, not simplified
var xRule = new SimpleRule(){
	execute: function( module, input){
		logInfo(" ################  xRule Line: "+__LINE__+"  #################");
		logInfo(" xRule::execute "+__LINE__, " input "+ input, " module "+ module, " uuid "+ uuid.randomUUID());
		
		for( var i in input){
			var ai = input[i];
			logInfo(" -- input "+i +" = "+ ai);
		}
		
	}
};
xRule.setTriggers([

Anybody an idea?

No one, who works with Javascript?

Ok, got it myself.

You have to get the item before you can use it with

var Wallplugs_i2 = getItem('Wallplugs_i2');

Then you can get the state via

Wallplugs_i2.state
