hi, @rytilahti I don't know how to fix the pipeline, the test is passed in my local environment 😥, could you help to review the code?

One reason that your new code fails to run in other environment is that
filenames in the miot_specs directory contains ':' (colon), which is not allowed in some filesystems
(I had that problem while testing your code, when I was repackaging your whl file in Windows)

Anyway, you can check error messages in the pipeline here

I'm not sure that it will pass the test, but my suggestion is

In the miot_spec_v2.py line 203, instead of
from . import miot_specs
you can try
from miio import miot_specs

add a blank _ _ init _ _.py file in miot_specs directory, if it is needed.

It looks like you hit this issue: lidatong/dataclasses-json#232

Can be reproduced locally if you run the tests with python 3.6.
