Hello, I’ve a rule for my garbage. But I get an error. But I couldn’t figure out what is caussing the error. Can someone look at my rule? rule "Tage bis Abfall berechnen" when Time cron "0 5 * 1/1 * ? *" or Item Restmuell changed or Item Biomuell changed or Item Papiermuell changed or Item …

In order to check where the error occurs(or better where the rule is left) place a logInfo behind any line you think it is worthwhile checking. Using a different string in each will help to find the error.

[image] Jeroen_K: rule “Abfalltermine sortieren” Looking a bit again, the rule “Abfalltermine sortieren” has a lot of Item triggers - which explains the multiple copies running, of course. As you seem to be setting up the value of these Items in other rules - have you considered what happens…

I’d add more log statements in the rule and now I see values of “NULL” : ==> /mnt/shares/Openhablog/openhab.log <== 2018-09-08 21:57:38.442 [INFO ] [e.smarthome.model.script.Afval.rules] - varAbfall1Datum: 2018-09-12T00:00:00.000+02:00 2018-09-08 21:57:38.444 [INFO ] [e.smarthome.model.script.Afv…

And now 5 minutes later: ==> /mnt/shares/Openhablog/openhab.log <== 2018-09-08 22:05:38.380 [ERROR] [ntime.internal.engine.RuleEngineImpl] - Rule 'Abfalltermine sortieren': An error occurred during the script execution: null 2018-09-08 22:05:38.450 [INFO ] [e.smarthome.model.script.Afval.rules] -…

I think that this part is causing the error: var i = 1 while ((i=i+1) < 6) { if (varAbfall1Datum > varAbfall2Datum) { varTempDatum = varAbfall1Datum varAbfall1Datum = varAbfall2Datum varAbfall2Datum = varTempDatum varTempArt = varAbfall1Art varAbfall1Art = varAbfall2Art varAbfa…

I’d any of the values on either side of the > or < comparisons are NULL I would expect to see an error like this.

I add log statements at the comparison and there are some variables with value ‘NULL’: 2018-09-09 09:21:59.244 [INFO ] [e.smarthome.model.script.Afval.rules] - varTempDatumnull 2018-09-09 09:21:59.247 [INFO ] [e.smarthome.model.script.Afval.rules] - varTempDatumnull 2018-09-09 09:21:59.256 [INFO …

All your Items start out as NULL, until something updates them. Maybe a rule, maybe a binding, maybe restore-on-startup. This is normal. Your rule deals with a collection of Items. It gets triggered when one of those Items gets updated. You probably need to think about what happens when the ru…

the only thing I want is the following widget. I don’t know if there is an easier way to accomplish that? [image] I don’t know if I need that comparison part in the rule.
