Knx and scene no more sending to bus

Add-ons Bindings

Hi all,

i have a knx item with a channel for a scene:

      Storen_Szene:
        type: number
        label: Storen_Szene
        description: ""
        config:
          ga: 17.001:31/2/13

if im changing the item, then it should send the scene to the bus:

2026-03-09 15:28:26.566 [INFO ] [openhab.event.ItemCommandEvent      ] - Item 'KNX_Winti_Storen_Szene' received command 0
2026-03-09 15:28:26.567 [INFO ] [penhab.event.ItemStatePredictedEvent] - Item 'KNX_Winti_Storen_Szene' predicted to become 0

if im opening the knx diagnosis and filtering for the groupnumber then i cannot see the scene value sent to bus.
i have verified, that the DTP ist 17.001 in the ETS.
last year with older openhab version this was working fine.

Other on off values or measurements from knx does not have problems to get them in or out of knx.

I have actually oh 5.1.3 installed. Could someone can give me a hint to get scenes again working?

OK, if someone has this problem too: switch the log of knx to level trace and send a value to the scene-item. on my side i got out by checking that trace-log that MAP-addon was needed and not available. On an update of openhab MAP was not correctly reinstalled (i did never uninstalled it).
new installation of this add-on solved it.

…maybe someone can help this information too
