MQTT v2 and Homekit

I have old slow computer running OpenHab2.4 MQTT v1.4 action binding + Homekit and external mosquitto MQTT broker, with all my devices in the item file, all working great

Planing and test new server
OpenHab24 : working
installed MQTT 2.4 : working
installed MQTT embedded: working
installed Homekit binding
created generic MQTT item and configured and woking usable in control tab(in paper UI)

but when connecting to apple homekit only openhab is shown but NO devices
tried looking for the device config file, but can not find one.
any help would be appreciated
Thank you
