Device information:

Issue: Device Not Supported

Name(s) of the device: Xiaomi Smart Air Purifier 4 Pro
Link: https://www.mi.com/global/product/xiaomi-smart-air-purifier-4-pro/
Model: zhimi.airp.vb4
Hardware version: esp32
Firmware version: 2.2.0

Additional context
Not entirely sure why they have two purifiers "4 Pro" models (well, one has the "Smart" label), but the vb4 model seems different from the earlier va2 whose support was committed last week. The difference seems largely just an additional PM10 field and a "display device unit" service that seems to let you control the temperature unit on the display remotely.

Had tried other models with no luck, if anyone has this running in Homeassistant please let me know.
