Python Error in miio - Xiaomi Smartmi Fresh Air (like Purifier 2/Pro)

Home Assistant release with the issue: 0.80.3 Last working Home Assistant release (if known): 0.79 Operating environment (Hass.io/Docker/Windows/etc.): Raspbian on Raspberry Pi 3+ Component/platform: zhimi.airpurifier.v6 (real zhimi.airfresh.va2) Problem-relevant configuration.yaml entries and (fill out even if it seems unimportant):

- platform: xiaomi_miio
    host: <ip adress>
    token: <token>
    name: Air Fresh Xiaomi
    model: zhimi.airpurifier.v6
    # model: zhimi.airfresh.va2

Description of problem:

On Home Assistant 0.79, I normally worked (on / off) xiaomi smartmi fresh air, which was registered in the config as zhimi.airpurifier.v6 (miiocli defines it as zhimi.airfresh.va2) After upgrading to 0.80, one day worked fine, but today when you restart, the Home Assistant shows an error like in https://github.com/home-assistant/home-assistant/issues/12031

I tried to update python-miio to the current master, but this did not fix the problem :(

sudo -u homeassistant -H -s
source /srv/homeassistant/bin/activate
pip3 install -U https://github.com/rytilahti/python-miio/archive/master.zip
