In the case of xiaomi devices, the problem is the devices. Plenty of threads discussing why that is, and what people have done to try to get them working with their ST hub (successfully for some, not so much for others).
But the bottom line is, they are not devices that are confirmed to work with ST, so please take any follow-up questions to those threads, rather than this one.
Edit: I also just noticed that you created a new thread to ask the same exact question. In the future, please just do that, rather than repeating the same question in another thread where it doesn’t really belong anyway.
