Sitemap: Historic date in text

Setup, Configuration and Use Items & Sitemaps
1

Hey guys,

I would like to get the historic state of an item as text in the sitemap. E.G. energy consumption in the past month.

This is easy if you use a chart. But I want just a number. Have anybody an idea how to solve this? Ot do I need a rule and more items for this?

best regards

You need an Item to show this value in the sitemap and a rule that does the calculation.
You might want to check the rule templates marketplace where I published two templates, one for actual energy consumption and one for historical.

Thanks @hmerk

This is a blocky rule right?

I want to do this as a rule with dsl code. As all other thinks.

So I tried to use your code. But I get an error in the log with my attempt.

configuration: {}
triggers:
  - id: "1"
    configuration:
      time: 00:01
    type: timer.TimeOfDayTrigger
conditions: []
actions:
  - inputs: {}
    id: "2"
    configuration:
      type: application/vnd.openhab.dsl.rule
      script: >-
        items.getItem(Haus_Ernergiezaehler_Hausstrom_Aktuelles_Jahr).postUpdate((items.getItem(Haus_Ernergiezaehler_Hausstrom).persistence.deltaSince(time.ZonedDateTime.now().minusDays(1),
         'rrd4j')));
         
         if (((time.ZonedDateTime.now()).dayOfYear()) == 1) {
                   items.getItem(Haus_Ernergiezaehler_Hausstrom_Aktuelles_Jahr).postUpdate((items.getItem(Haus_Ernergiezaehler_Hausstrom).persistence.deltaSince(time.ZonedDateTime.now().minusYears(1), 'rrd4j')));
                 }
    type: script.ScriptAction

The error is:

2025-05-14 20:19:03.147 [ERROR] [.handler.AbstractScriptModuleHandler] - Script execution of rule with UID ‘Calculation_Haus_Ernergiezaehler_Hausstrom_Aktuelles_Jahr’ failed: if ((( ___ time.ZonedDateTime.now()).dayOfYear()) == 1) {

}

  1. The method or field time is undefined; line 1, column 6, length 4
  2. The method or field items is undefined; line 2, column 63, length 5
  3. The method or field items is undefined; line 2, column 136, length 5
  4. The method or field time is undefined; line 2, column 205, length 4

Do you have any suggestion where my mistake is?

Thank you for your help :slight_smile:

Sorry, but I don’t use DSL Rules, so cannot tell the correct syntax. Blockly creates Javascript code.
