How to use Qubino Flush Dimmer ZMNHDD with 2-way switch only?


i own a Qubino Flush Dimmer ZMNHDD and i want to use it with a 2-way (Bi-Stable) switch.
When the switch changes its state the light should turn fully on if its turned off and vice versa.
I only want to control the dimming via Openhab2.
Until now i experimented with several configuration options but i did not succeed. My forum search and Internet search were not successfull.
Do you have an idea how to achieve this?

Thanks for your help.

I’m using Openhab 2.4 with official/stable Zwave Binding.

Does anyone have an idea how to use the dimmer as an on/off switch with bi-stable switch attached to l1?
