TypeError: isinstance() arg 2 must be a type or tuple of types

[nzhou]

My chuangmi plug v1 was discovered correctly, however, when I ran "miplug --ip $IP --token $TOKEN -d", I got the follow error:
File "/Users/ningzhou/anaconda/envs/tf/lib/python3.6/site-packages/click/core.py", line 449, in find_object
if isinstance(node.obj, object_type):
TypeError: isinstance() arg 2 must be a type or tuple of types

I have a vague impression that this has sth to do with Python 3 + Anaconda, but was not very sure. Or could it be from the deprecated object? isinstance should handle inheritance correctly though. Any hint where should I start to fix it? If I just comment out the line "if isinstance(node.obj, object_type):", miplug runs the commands correctly. Full debug output below:

I had exactly the same error.
Try this: miiocli chuangmiplug --ip ipadd --token yourtoken status

[kjw3898]

I had exactly the same error also
but not work with command miiocli
when you install with "pip install python-miio", you can't use miiocli (at least in my case)
solution:
type "pip uninstall python-miio" on cmd or terminal
download github zip flie -> unzip -> go to unzip path on cmd or terminal -> type "python setup.py install"

The command line tool "miplug" will be fixed with the release of python-miio 0.4.0. The new unified command line interface (miiocli) will be introduced with the release of version 0.4.0, too. Right now miiocli isn't part of the stable release. Please use miiocli in future. The old command line tools will resign some day.
