I have the same problem. The Xiaomi Smart Air Purifier 4 is not supported.

I get the following error:
Logger: homeassistant.components.xiaomi_miio
Quelle: components/xiaomi_miio/init.py:164
Integration: Xiaomi Miio (Dokumentation, Probleme)

Unsupported device found! Please create an issue at https://github.com/syssi/xiaomi_airpurifier/issues and provide the following data: zhimi.airp.mb5a
