KNX Dimmer Configuration

I wonder if a KNX Dimmer using 5 KNX group addresses like this is properly implemented via OH 3.2

1/1/0 switch on/off command
1/1/1 switch on/off state
1/1/2 increase/decrease command
1/1/3 absolute dimmer level command as %
1/1/4 absolute dimmer level state as %

can it be configured via the Thing settings in the OH3 Main User interface. Has anybody done it this way? How will the “state” addresses be implemented as there are only 3 group address entry fields available?
Or do I need to define the Thing by coding from scratch? And how, if so?

`1/1/0 switch on/off command
1/1/3 absolute dimmer level command as %
1/1/4 absolute dimmer level state as %’

That is the only groups you need. Also use auto update false so you get the real feedback from group 1/1/4 not openhab

i use 4 groups: switch command + switch states and dimmer level command + state.
here is how it looks like in mainUI → code (here are 2 dimmers configured)

UID: knx:device:scn_ip:AKD_1
label: Dimmaktor 1
thingTypeUID: knx:device
configuration:
  pingInterval: 300
  address: 1.0.13
  readInterval: 0
  fetch: false
bridgeUID: knx:ip:scn_ip
location: KNX
channels:
  - id: channel_a
    channelTypeUID: knx:dimmer
    label: Kanal A
    description: null
    configuration:
      position: 1/4/10+<1/5/10
      switch: 1/1/10+<1/2/10
  - id: channel_b
    channelTypeUID: knx:dimmer
    label: Kanal B
    description: null
    configuration:
      position: 1/4/11+<1/5/11
      switch: 1/1/11+<1/2/11

or UI

and each channel is linked to an item of type Dimmer.

Got it. In deed there is no need for the 3rd address, as increase and decrease sent from the iPhone is alway translated to a percentage number. Thank you for the help, works fine.
