Hi,
I’ve managed to remove it from the Devices list.
I found the solution in this post:
Open the core.device_registry
file and remove the roque device from it. (Make a copy first, and if you remove the last device in the file don’t forget to remove the ‘,’ after the ‘}’ at the new latest device in the file).
Then restart HA and it’s gone.
But I still think its a bug, should we log an issue for this?
I don’t know in which part, does this belongs to Core?
