OpenHAB 2.3 is ancient. That device was last updated in the database in June, after 2.4 was released. The database is part of the zwave binding. You could update to the latest testing release, 2.5M3. 2.5 will likely get released at the end of this year, about 6 months behind the original schedule.
There has been much work integrating Eclipse Smart Home and redesigning the build system. Milestone 3 has been stable for me.
Thanks! Had postponed upgrade since my 2.3 installation worked like a charm… but now Im running on 2.5 and the device was of course identified correctly…
