HomeKit System Integration: Accessory of Type "Filter" not Working

Hej there,

I am trying to export an accessory of type “Filter” to my Home.app in iOS.

Following the documentation I set:

Group gFilter "Filter" (gFilter) ["Equipment"] {homekit="Filter"}
Switch iFilter_hfci "Filter Change Indicator" (gFilter) ["Point"] {homekit="Filter.FilterChangeIndication" [NO_CHANGE_NEEDED="OFF",CHANGE_NEEDED="ON"]}

But then after restarting the log:tail in openhab-cli console show:

your code goes here16:15:17.066 [INFO ] [omekit.internal.HomekitChangeListener] - Created 5 HomeKit items in instance 1.

16:15:17.066 [WARN ] [r.impl.json.CharacteristicsController] - Accessory 611298718 has no characteristics or does not exist. Request: /characteristics?id=1226685708.9,611298718.9,611298718.12,611298718.11,611298718.10,1660712435.9

Is there a bug in the code, is it nowaydays not supported anymore by Apple or am I doing something wrong there?

Thanks in advance.
