Xiaomi gateway: include 2nd Mi Control Hub device not work?

Hello,

I have correct include a Xiaomi Gateway (Mi Control Hub) and it works fine.
Now I have bought a 2nd Xiaomi device and I tried to include in OpenHub, but it do not work. OH can’t find the new device.
Have everybody include two (or more) Mi Control Hub’s? It is possible to include more then one?

Thank you!
Michael

Does anyone know if it is in principle possible to integrate two identical Xiaomi Hubs devices in OpenHAB?
Regards
Michael
