I have 2 problems.

Group Addresses of a Main Group Number, but I cant do it. I dont know how.
KNX DEVICE. Configuration. Group Addr
I want to read any group address that maingroupnumber is 11.
I have this options:
a.dropdown list
Configuration. Group Addr:
If I select from dropdown list 11/-/- = ERROR

b.$Env variable to read the group address from an environment variable.
I don't know how.

c.Select Universal mode (listen to all Group Addresses) to react to ALL group addresses.
Configuration. Group Addr:
I did select this one, but I would like to filter.

  1. I want to read and write in a group address that is:
    11/5/X
    Where X is msg.gainfo.ganumber from a node that gives the info.
    For that:
    KNX DEVICE.
    Configuration. Group Addr:

    I don't know how to use $Env
