xiaomi_airpurifier: Cannot import name 'AirHumidifierMiot' from 'miio'" - workaround

I got the error Platform error fan.xiaomi_miio_airpurifier - cannot import name 'FanMiot' from 'miio' today with HA 0.118.0 after upgrading xiaomi_airpurifier from 0.6.1 to 0.6.2 I tried HACS and manual install from downloaded xiaomi_airpurifier-develop.zip Downgraded back to 0.6.1

I have another error with this model. Errors starts with last version, before works fine

Platform error fan.xiaomi_miio_airpurifier - cannot import name 'FanMiot' from 'miio' (/usr/local/lib/python3.8/site-packages/miio/__init__.py)

I use homeassistant/qemux86-64-homeassistant:0.117.5 container, it has 0.5.4 python-miio

bash-4.3# docker exec -it 64114 bash
bash-5.0# pip3 list | grep miio
python-miio                      0.5.4

I found a workaround which works for me. Copy the official xiaomi_miio component to your custom_components folder and edit the manifest.json. The updated dependencies must be used here:

{
  "domain": "xiaomi_miio",
  "name": "Xiaomi Miio",
  "config_flow": true,
  "documentation": "https://www.home-assistant.io/integrations/xiaomi_miio",
  "requirements": ["construct==2.10.56", "python-miio==0.5.4"],
  "codeowners": ["@rytilahti", "@syssi", "@starkillerOG"],
  "zeroconf": ["_miio._udp.local."]
}

Reboot HA. This solves the issue of different required python-miio and construct versions. All manifest.json’s of python-miio dependend custom components requires the same version/line at the manifest:

  "requirements": ["construct==2.10.56", "python-miio==0.5.4"],

If this is fulfilled the errors are gone. As soon HA 0.119 is reased the xiaomi_miio folder can be removed again.

I hit the same issue today:

If I check the age of the __init__.py we can see the pip package is installed on every reboot:

$ ls -l lib/python3.7/site-packages/miio/__init__.py         
-rw-r--r-- 1 homeassistant homeassistant 2483 Nov 18 15:15 lib/python3.7/site-packages/miio/__init__.py

As soon as HA and the custom component uses the same python-miio version the issue will be gone.

@syssi That’s what I did 😉 Guten Rutsch ins neue Jahr. Greetings from Shanghai

@neo799 just update the manifest.json of the heater to:

"construct==2.10.56",
"python-miio>=0.5.4"
