Failed adding Fibaro FGBS-222

I have had a system running a single Fibaro Smart Implant (FGBS-222). I have been trying to add a second one and now neither works.

I have tried both secure and insecure additions. In all cases, it shows a node with a number but none of the functions/entities that this device supports. Also if I re-interview the device, it completes immediately, under one second. That does not seem right. Other devices in the Z-wave network are still working. I have tried using the QR code as well as the 5 digit code for secure additions. Nothing seems to make a difference.

The OS and supervisor have been updated to the latest version. It now says that there are no further updates available.
