No items show up in homekit

Hi all,

For days i am trying to get some lights in my homekit on my phone. After day strugling with the homekit add-on i was able to add OpenHAB accessory in my Homekit on my phone.

I also managed to get a dimmer working on my paperUI. When I slide the dimmer, a light is working.
Until so far, no problems.

I add a KNX.items file with a dimmer, but no success. I do see my openHAB accessory in Homekit but no dimmer. When I check Karaf console with smarthome:items list My demoDimmer is there…

Below my Things a items file. What I am doing wrong?

KNX.things:

     Bridge knx:ip:GIRA2167 "KNX IP Interface" [
        type="TUNNEL",
        ipAddress="192.168.1.101",
        portNumber=3671,
        localIp="192.168.1.107",
        readingPause=50,
        responseTimeout=10,
        readRetriesLimit=3,
        autoReconnectPeriod=60,
        localSourceAddr="0.0.0" ]
        {
          Thing device MDT_AKD_0401 "MDT AKD 0401" @"KNX" [  ]
          {
            Type dimmer: demoDimmer "Channel 1" [ switch="0/0/18+<0/4/17", position="0/5/17+<0/6/17" ]
          }
        }

And my KNX.items:

Dimmer demoDimmer "Channel 1" {channel="knx:device:Gira2167:MDT_AKD_0401:demoDimmer"}

to me looks like homekit tag is missing, e.g

Dimmer demoDimmer "Channel 1" {homekit="Lighting ", channel="knx:device:Gira2167:MDT_AKD_0401:demoDimmer"}
