Regional server. What's for ... again


Sep 10, 2021
Got a eScooter Pro 2 from a friend.
I have to change my Xiaomi Home App from Ireland where I am, and have number of home devices linked to, to Russia before the eScooter can paired with the App, and therefore control the eScooter.
Is this means the device - eScooter I now have is from Russia ?
Can I change the region back to where I am - Ireland, and still able to pair the eScooter ?
What exactly Xiaomi App server is use for ? Does it linked to the service where the paired device is registered initially ?
Any help will be greatly appropriated.
