Thanks 👍 If you don't mind installing python-kasa from git (https://github.com/python-kasa/python-kasa) and running kasa dump-discover, and upload the result file to https://github.com/python-kasa/python-kasa/tree/master/kasa/tests/fixtures that would be great.

I can't get that to run, I get this error:

SyntaxError: invalid syntax

I'm presuming that's because it's trying to use python 2.7 instead of 3.7, but I have no idea how to force it to use python 3.7; I never use python, so this isn't something I'm used to handling. I've downloaded and installed python 3.7 in addition to my mac's copy of 2.7.

Repo is cloned, installed using python setup.py install. I just reran through all of this and actually I see I get errors when installing the project.

Sorry for this to be a burden, not something I was expecting to have to do! Any tips to get this working?

No worries, thanks for the effort!

I think the proper way on OSX is to install python3 with brew, and then use virtualenv like shown in https://gist.github.com/pandafulmanda/730a9355e088a9970b18275cb9eadef3

When the environment has been activated, you can simply execute python and pip and it is using the one installed in that virtual environment.

Had to submit another PR cause I got the model number wrong 🤦‍♂ #11831

However, I have now been able to run the kasa discovery test, so a PR is landing for that shortly. Thanks for the advice on using virtualenv
