Aeotec Siren Gen5 ZW080 no device available?

[Zorc]

Using:
Domoticz V4.11563 (beta) on debian buster 10.2 with AEON Labs ZW090 Z-Stick Gen5 USB stick as controller.
I've been experimenting with a few different z wave devices (previously only used 433mhz Rfxcom), and got them working without much trouble.

However I'm running into some trouble with the Aeotec Siren Gen5 ZW080.
It shows up as a node, and can be configured. It is also available on the openzwave control panel.
However, I don't get any associated devices under menu -> setup->devices.

I've tried excluding/including a few times, updated to the latest beta version, but no succes.

Any clue/hint on what I could try or look into would be nice!
