[SOLVED] DateTime Items compare against fixed DateTimes

[fibu-freak (Peter)]

thx. I tested the proposal of Scott.
But when I set free the day0-Constant the error comes up.

[fibu-freak (Peter)]

you are right. I changed the Rule to:

rule test_date2_owm
  when
   Item Dummy3 received command ON 
  then

  var day0String = localLastMeasurement.state.format("%1$tY%1$tm%1$td")
   logInfo ("owm.test_date1", " String-Item: " + day0String)
  val day0 = new DateTime.valueOf(localLastMeasurement.state.toString)
   logInfo ("owm.test_date1", "Current-Time-Item: " + day0.toString )
//  val day1String = day0String.plusDays(1).toString("yyMMdd")
//   logInfo ("owm.test_date1", "day 1 -Time-Item: " + day1String)
//  val day2String = day0.plusDays(2).toString("yyMMdd")
//   logInfo ("owm.test_date1", "day 2 -Time-Item: " + day2String)
end

Do you have a proper definition for me?

@fibu-freak

Do you have a proper definition for me?

See my previous post…

[fibu-freak (Peter)]

Sorry i’m a silly fool, didn’t see the forest for the trees. Now it works excellent.

This is a further step to my goal.
thx to you all @5iver, @vzorglub, @rlkoshak

[vzorglub (Vincent Regaud)]

Can you post your working code, thanks

[fibu-freak (Peter)]

Hi, @vzorglub,
i will do this as fast as i can.
At the moment i solved the problem of DateTime with the help of all of you.
Now im beginning to create the rest of the rule. Pls give me a while as I’m an old man , and of course no programming specialist.
thx for your interest, i keep you informed.

Hi, all @vzorglub @5iver @rlkoshak
thought i have it. But i’m in trouble with a command:

tempItemTemperature.addGroupName("gTemp_day0")   //dynamic item-name brings the error

This is the rule:

import org.eclipse.smarthome.model.script.ScriptServiceUtil
  var dayindex = 0  // day index
  var dcountindex = 0 // items a day
  var sum_temp_curr =0

   Item Dummy3 received command ON  or
   Item localLastMeasurement changed
  then

   var itemindex = 3 //item index
   var itemincrement  = 3 //item step

   var count_day0 = 1

Looks like a lot of stuff, but most of it, is explanation and logInfo.

When usung the above command, i get the following error:

It seems as if the Pointer-Item (hope this is correct) tempItemTemperature has problems with this kind of addGroup-Method. But in the logger, two lines before the ERROR the correct Item is shown tempItemTemperature: localHourlyForecast3Temperature (Type=NumberItem, State=5.11 °C, Label=Temperature in 03 hours, Category=temperature, Groups=[gOWM])

If you like to have the complete item-set i can post it.
Any hints or tips are welcome.

[HomeAutomation]

maybe this is a problem which is still not fixed.

To add a item to a group I use two lines of code:

                group.addMember(item.getName())
                item.addGroupName(group.getName())

Without both I see inconsistence in the group membership. You can check this by looking at the group membership from the point of the group and of the item.

group.getMembers
item.getGroupNames

[5iver (Scott Rushworth)]

@fibu-freak

It seems as if the Pointer-Item (hope this is correct) tempItemTemperature has problems with this kind of addGroup-Method.

addGroupName is a method of GenericItem, but ScriptServiceUtil returns Item. You’ll need to do a conversion…

var GenericItem tempItemTimestamp = ScriptServiceUtil.getItemRegistry.getItem("localHourlyForecast"+itemindex+"Timestamp") as GenericItem

[fibu-freak (Peter)]

Hi, @5iver,
changed it as you described, to
var GenericItem tempItemTemperature = ScriptServiceUtil.getItemRegistry.getItem("localHourlyForecast"+itemindex+"Temperature") as GenericItem
Now works perfectly.

But next problem comes up when tryin to remove all items from the groups(e.g. “gTemp_day5”)

I tried: gTemp_day5.removeUsers(ALL) and gTemp_day5.deleteMembers(ALL) and gTemp_day5.removeMembers(ALL), but always got this errors.

i’m desperate

@fibu-freak

I could give you the answer, but I’d rather show you how to find it yourself . Go to the ESH repo, then search for GroupItem.java, select that file in the results, select the master branch, and then read the methods provided. A simpler way is to use VS Code with the OH extension and LSP enabled, then typing in gTemp_day5. (note the period) will display all available methods. Hint: removeMembers is not a valid method.

Once you’ve found your answer, you may want to consider iterating over the group members and removing the group from each of them.

[scottk (Scott Karns)]

To add to what @5iver has said regarding on-the-fly (dynamic) control of group membership, I would add that in the code and rules I use, I have found that it may be better to first remove the group from each member item’s list of groups to which it belongs before removing the member items from the GroupItems. I do this with JSR223 Jython, but the methods used are from the GenericItem and GroupItem ESH java classes, so the techniques should be the same using DSL rules.

[Update]
This thread has wandered off of the original topic, it might be best to start a new thread to discuss dynamic control of group membership.

[5iver (Scott Rushworth)]

@scottk

I have found that it may be better to first remove the group from each member item’s list of groups to which it belongs before removing the member items from the GroupItems.

Did you find that you needed to do both? I used this in my rules a while back and only used GroupItem.addMember/removeMember, and the items’ group membership were being properly updated. I no longer do this, so maybe it has changed.

[scottk (Scott Karns)]

I haven’t fiddled with it for some time, but it is possible that there was some delay after removing the group from each member item before the member items were removed from the group.

I have a simple script that iterates over all items, listing member items when group items are encountered. When running this script I discovered what I considered to be dangling group-member relationships. That discovery led me to take the two-pronged approach to removing member items from groups.

Maybe after removing the group from a member item’s list of groups, checking the list of the group item’s members for the presence of that member item would help determine whether or not it is necessary to remove the member item from the group.

[fibu-freak (Peter)]

thx, a lot for your help up to this point. But it seems, i even have problems to find the wiki for the provided methods in the ESH repo. When using your hyperlink i come up here:

and when selecting “In this repository” or the other i can’t find a master branch. I only see this:

So for the moment this is bit to much stuff to learn and understand for me. I’m even too stupid to find a simple website.
I will put the project aside for a while as i think it’s a bit to big for me.

[5iver (Scott Rushworth)]

In your second image, select the GroupItem.java file to view it, from there you can select the branch. Don’t give up yet… you’re real close!

[psst… the method you’re looking for is in my last post ]

[fibu-freak (Peter)]

The moment of frustration was very short. Cry Uncle ? Never
As i have no experience in Programming Languages like Java/DSL. it’s sometimes hard for me to understand what is meant and transpose it.

There is a little trick i used to summarize the Temperature-Items, as they have the Measurement-Sign in the Item-State. I used a constant (celsius = -273.15) in my calculations.(I didn’t find a Filter. But this doesn’t work with Pressure-Items). It’s not professional Code, it’s a kind of spaghetti-code, but it works.

I’m thinking about undoing UoM in my .items-file and bring it to the sitemap, for easier calculations. But not forgetting the hints, you gave me in your last post and try it. I would like to study them and learn from.

thx again, Peter

Hi @scottk. What kind of script is this ? Can you post it ?

The following link is to my post on the thread [JSR223-Jython] Simplified rule definition (similar to Rules DSL) and universal decorator where I described the script in question.

@5iver, I am really enjoying writing rules using the decorators you added to the openHAB Jython libraries, thank you!
