I´m only working with .things files and almost nothing in the PaperUI.
It should have the iCloud Account in the PaperUI inbox after installing/starting the binding.
I created a new account, added him to the family share and used this for my bridge.
This account is not allowed to buy anything and therefore i´m not so concerned about the password stored in openHAB.
This could be caused by your first attempt before the child account.
First try to restart your openHAB service or your hardware.
If that doesn´t help try to clean the cache with:
sudo service openhab2 stop
// wait a moment for openhHAB to stop
sudo openhab-cli clean-cache
sudo service openhab2 start
Did you checked the log?
Have a look at the logs from http://<your-oH-IP>:9001 and may add a filter for iCloud
with clearing the cache I’ve solve the issue with duplicated devices … but the wrong device is still there. I see a Mac (offline) and not another Mac that is online and perfectly visible in the list when I check in icloud.com
mmmm
edit: the only difference is the mac online can’t activate “find my Mac” because missing the recovery partition (not avaiable when you create a raid solution)
