Persistence on a group


I want to log all items in a group in a rr4j, but I can not make it work
my group i want to log is (Temperatur)

I have the following items.

Number Setpunkt_Kontor          "Setpunkt [%.1f °C]" <temperature>   (Temperatur, Kontor)["TargetTemperature"]  {ihc="0x102ff14", autoupdate="fa$
Number Temperature_Kontor       "Rum Temperatur [%.1f °C]" <temperature>   (Temperatur, Kontor) ["CurrentTemperature"]  {ihc="0x9d4a14", autoupd$
Number Fugtighed_Kontor         "Fugtniveau [%.1f %%]"          <humidity>      (Kontor)                                        ["CurrentHumidit$
Number Temperature_Walkin       "Rum Temperatur [%.1f °C]"              <temperature>   (Temperatur, Walkin)            ["CurrentHumidity"]     $
Number Temperature_Sovev        "Rum Temperatur [%.1f °C]" <temperature>   (Temperatur, Sovev)                                          ["Curren$
Number Temperature_lillewc      "Rum Temperatur [%.1f °C]" <temperature>   (Temperatur, Toilet)                                         ["Curren$
Number Temperature_lillewc2     "Gulv Temperatur [%.1f °C]" <temperature>  (Toilet)                                             ["CurrentTempera$
Number Temperature_Bryggers     "Rum Temperatur [%.1f °C]" <temperature>   (Temperatur, Bryggers)                                               $
Number Temperature_Bryggers2"Gulv Temperatur [%.1f °C]" <temperature>  (Bryggers)                                              ["CurrentTempera$

I have tried to make the following persistence file

Strategies {
        everyMinute : "0 * * * * ?"
//      everyHour : "0 0 * * * ?"
//      everyDay : "0 0 0 * * ?"
//      everyWeek :"0 0 0 0 * ?"

Items {
        Temperatur* : strategy = everyMinute


At the frit sight a Group item is missing. So not created yet just create the following

Group Temperatur "My Temperatures" <temperature>


Thanks, it worked
