Connect XIAOMI Smoke Detector via DeCONZ


I am seeking for help in connecting a XIAOMI Smoke Detector via DeCONZ binding.

My setup:
Raspberry Pi 3b with Openhab
(experimental) second Raspi with DeCONZ installed
Openhab is connected with the DeCONZ instance and up and running
Already some Hue Bulbs and a Osram power socket are connected within this system, all via my ConBee II stick

The point where I am stuck now is how to bring the XIAOMI Smoke Detector into Openhab. It is shown already in DeCONZ.

Any ideas and experiences?

Many thanks
