HomeKit in Openhab2 on Qnap

a friend of mine installed openhab2 on his Qnap. He also wanted to be able to add HomeKit abilities. He installed the HomeKit add-on and was able to add the obenhab bridge to HomeKit. He could not yet manage to add his things to HomeKit. I managed to get it to work on my RPi3, but the same approach does not seem to work.
How to add HomeKit things on a qnap?
I hope someone can help me.

I have the same problem
First I have openhanded installed on my MAC… the HomeKit worked just fine…
Then i moved the files to my QNAP now the HomeKit won’t pair ?

It is not the HomeKit itself, but rather the items that I cannot add. I read a tutorial for the raspberry pi, and it suggests to create a HomeKit.items file. On my pi it works great. But that did not work on the qnap. Is there another way of adding HomeKit items or linking already added openhab items to the to HomeKit? I hope someone can point me in the right direction.
