Roborock s50 and Xiaomi Gateways (Aqara) help?


My Roborock arrived today and I set it up via the Mii Home app, it then said I needed to change the region to Europe, which I did… it works perfectly… so I go back to China as I have 3 Gateways and all the devices have vanished. HA still works fine, but do I need to set them all up again but in the Europe Location please? as I will want to add more sensors in the future.
