I bought a Xiaomi Vacuum S40 Pro but when integrating in home assistant, the device cannot be found. The integration works because I see the Mii Purifier 3C and it works correctly

How to Reproduce / 复现步骤

1. Add a Xiaomi Vacuum S40 Pro to the Mii Home app
2. Not see it in home assistant at all

Expected Behavior / 预期结果

I expect to be able to control the vacuum via the integration

It seems that you select Mainland China as the login region. xiaomi.vacuum.ov71gl is not avaliable in China. It is an export product and its MIoT-Spec-V2 is not released on the cloud service in Mainland China region.
Can xiaomi.vacuum.ov71gl be shown in your Mi Home APP with zhimi.airpurifier.mb4? From the backend, I can see that you have only one device that is the airpurifier under your account in Mainland China.

@SusanPhevos my account was created with the region Mainland China so that is why i selected that in HASS. in the Xiaomi Home app, i am also logged in in the region Mainland China and i see both devices

[rursache]

i can confirm that if i select region Europe in HASS, the vacuum is being detected

thank you @SusanPhevos !
