[SOLVED] DateTime Items compare against fixed DateTimes

Hi @vzorglub, thx for reply.
I’m using the new OpenWeatherMap-Binding, which gives me information about current temperature, pressure, etc. and forecast-info for those values in 3-hour-steps up to 5 days.
I want to achieve to adress the several forecast-values to a fixed day (current, day1, day2…day5). The problem is that forecast-period slides every 3 hours. The current time comes from the item localLastMeasurement of my owm.items-file.
Eg. at 22:20/10:20 pm the 3-hour-forecast(01:00/01:am) belongs to “day1” and of course the next 7 forcasts too. But at 00:20 all those forcasts are belonging to the “current” day and the next 8 to “day1” etc.
In detai i want to achieve:

  1. declaring the variables current, day1, day2...day5 in the rule, beginning from localLastMeasurement which should be transformed in a value like “yymmdd” or “yy-mm-dd” or “a, yy-mm-dd” (a = day-name), and of course corresponding variable for summarizing temp, hum, etc for the corresponding day (eg. day1_temp_sum)
  2. defining the loops (while, if, etc). First i’m using a While-Loop where i get the several items from the virtual item corresponding with it, beginning with the TimeStamp, then Temperature, Humidity, etc. The Solution to do so, i found here from @5iver and also post from @rlkoshak.
    Next I will compare the Timestamp item (transormed in the same way as above) with the variable “day1…5” and then adding the virtual Temp-Item to variable “day1…5_temp_sum”.
  3. At the very end i want to calculate an average for daily temp, hum, etc., or min/max. The result can look like this (from my "normal weather-binding with yahoo-provider)

After the first post i made some changes in my items.File (no more UoM) and in th Test-Rule.

owm.items without UoM for localHourlyForecast3Temperature to localHourlyForecast12Temperature:

I made this change for summarazing the values in the rule. Now this works. Perhaps there’s a better solution.

And the Test-Rule-File is:

import org.eclipse.smarthome.model.script.ScriptServiceUtil
  var dayindex = 0  // day index
  var dcountindex = 0 // items a day
  var sum_temp_curr =0
 
rule owmSummarize_test
  when
   Item Dummy3 received command ON or
	 Item localLastMeasurement changed
  then
   var itemindex = 3 //item index
   var itemstep  = 3 //item step
   var count_day1 = 0
   var avg_temp_day1 = 0
   var Number sum_temp_day1 =0

   var current = localLastMeasurement.state.format("%1$tY%1$tm%1$td")
   logInfo ("owm.owmSummarize", "Current-Time-Item: " + current)
  while (itemindex >=0 && itemindex <12)
  {
   var testItemTimestamp = ScriptServiceUtil.getItemRegistry.getItem("localHourlyForecast"+itemindex+"Timestamp")
   var testItemTemperature = ScriptServiceUtil.getItemRegistry.getItem("localHourlyForecast"+itemindex+"Temperature")
   logInfo ("owm.owmSummarize", "Timestamp-Item: " + testItemTimestamp + " :Temperature-Item: " + testItemTemperature)
   itemindex = itemindex + itemstep
   count_day1 = count_day1 + 1
   sum_temp_day1 = sum_temp_day1 + testItemTemperature.state  //doesn't work - without UoM in items-file it works
   logInfo ("owm.owmSummarize", " Count:  " + count_day1 + " Summe: " + sum_temp_day1 + " itemindex: " + itemindex)

  }
    avg_temp_day1 = sum_temp_day1 / count_day1   //doesn't work - works when not using UoM in items-file
   logInfo ("owm.owmSummarize", "Ende:  " + itemindex + " :Schrittweite:  " + itemstep + " Temp-AVG:  " + avg_temp_day1)
end

And the logger gives:

I get a sum and an average. So the Torso-Rule seems to work.

I hope you can understand what i have trying to explain in my simple, amateurishly words. Please be mercifully with me.

Thx
