I bought same sensor “Mi Door and Window Sensor 2” recently ( Model: MCCGQ02HL ) and I found this page 
There is the link: https://mistore.se/products/mi-door-and-window-sensor-2?variant=41957728092389
So I guess the solution will be, buy a “Xiaomi Smart Home Hub 2” and bridge sensor to homey via the hub, am I right? Or there is another better solution?
Thanks in advance
