OH3.3/KNX and heating HVAC settings

Running OH3.3-release and KNX with mostly GIRA components.

So, after a switch I don’t get HVAC settings up and running again? What did I miss here? first, the ETS-config didn’t change at all. It’s a GIRA 5145 00 (TS 3plus) and the HVAC mode is done via 1byte (not separate 1bit for each mode):

So, there’s the GA 8/5/1 for living room with a 20.102 HVAC Mode for setting the mode (works fine with the sensor and does, what it should)

In openHAB I added a Weinzierl IP Interface 730 as a bridge and it also does, what it should.
I added “virtual” devices for each KNX actor and did so with my TS3plus:

UID: knx:device:local:1_1_21-WoZi3plus5
label: KNX 1.1.21 WoZi 3 plus 5fach
thingTypeUID: knx:device
  pingInterval: 600
  address: 1.1.21
  readInterval: 0
  fetch: true
bridgeUID: knx:ip:local
  - id: WoZiTempIst
    channelTypeUID: knx:number

      ga: 8/1/1
  - id: WoZiTempSoll
    channelTypeUID: knx:number
    label: Soll Temperatur Wohnzimmer
    description: Eingang 80 / Ausgang 104
      ga: 8/1/2+<8/1/3
  - id: WoZiHVAC
    channelTypeUID: knx:number
    label: HVAC Wohnzimmer
    description: Eingang 82 / Ausgang 90
      WRONG!!!!!! ga: 5.010:8/5/1+<5.010:8/5/11
      CORRECT!!!! ga: 5.010:8/5/1+<8/5/11

I can change the SetTemp (8/1/2) and read the Temp (8/1/1) just fine.

I added the HVAC-item as follows:

If the GA sends its value, there’s no reaction in the TRACE-log of the knx-binding:

2022-10-27 09:02:47.253 [TRACE] [nx.internal.client.AbstractKNXClient] - Received a Group Read Response telegram from '1.1.21' to '8/5/11' with value '[4]'

nothing more

If I try to write the status, I get the following:

2022-10-27 08:56:12.055 [TRACE] [.internal.handler.DeviceThingHandler] - Handling command '3' for channel 'knx:device:local:1_1_21-WoZi3plus5:WoZiHVAC'

2022-10-27 08:56:12.067 [INFO ] [openhab.event.ItemStateChangedEvent ] - Item 'KNX_LivingHVAC' changed from 2.0 to 3

What did I miss? The configuration is nearly(?) identical with the “old” one, which worked…?

It’s very strange. I migrated OH3.3 to OH3.3 (just refactored my item-Names and structure), but the solution was like the one described here:
