I am running OH 4.0.1 and just set up Homekit integration using the instructions on the add-on page. I was able to add the accessory only when my phone is connected to same the local LAN/WLAN as the openHAB server. When I tried with the phone connected via mobile data/public Internet it did not work.
Is there a way to set up the connection between openHAB and the Apple devices via public Internet?
And another question: if I add/change Homekit metadata of items, is there anything I need to do for the changes to be registered on the Apple side, or does that work automagically?
