  • Platform information:

    • Hardware: PI2
    • OS: OpenHabian
    • openHAB version: 2.1

  • Issue of the topic: Hello, i have made a group of Windowcontacts. All Items have a valid state and the state changes, but the groupstate ist always “NULL”.
    So i made a Testgroup with one Contact and the groupstate is also “NULL”. So whats wrong?

  • Please post configurations (if applicable):

    • Items configuration related to the issue
      ’’‘Contact Tuer_EG_Eingang “Eingangstür” (EG_Flur, gFe, gTest) { knx=“1/5/81”}’’’

Here`s my Group:
’’‘Group:Contact gTest (gOG)’’’

Thanks for your help.

Try this.

Group:Contact gTest "GTest[%s]"
Contact Tuer_EG_Eingang "Eingangstür[%s]" (gTest) { knx=“1/5/81”}

sitemap default label="default" {
    Group item=gTest
    }

In 2.2 it works and in 2.1 it has to work also.

Restart openHAB, if you have problems.

Wouldn’t you want to define an aggregate function for your group (AND, OR)?
https://docs.openhab.org/configuration/items.html#group-type

It says that defaults to EQUAL, which with a bunch of contacts, some open some closed, would result in UNDEF

Group:Contact:OR(OPEN,CLOSED) gTest
should tell you if any one is open

Thank you, i would try that for the group gFe.
I great a group with 1 item in it (gTest) and the state should be the same as the one Contact. Right? But i get the state NULL in Karaf for the group gTest and OPEN or CLOSED for the Contact

Thank you very much.
Now it works.
The solution are from both. I set the group aggregate function but nothing changed. Then I restart openhab and now it works. Thanks
