No Luminance from Steinel L 810 LED iHF Sensor-switched outdoor up and downlighting

Hello, I have Openhabian (Openhab3.1.0) installed on Raspberry 4 with Z-Wave USB stick.
I have installed a lamp (Steinel L 810 LED iHF Sensor-switched outdoor up and downlighting) and linked it with 2 items.

https://www.opensmarthouse.org/zwavedatabase/705

One item for alarm (burglar) 2 = motion detection and one item for sensor (luminance) = light intensity.
The motion detection works very well, but for luminance I always get the value (NULL).
But in the Log Viewer a Sensor Value = e.g.1282 is displayed.
Here is an excerpt from the log viewer.

Why does the luminance sensor not show anything in Openhab?
Thanks for the support.
