You are missing the Crypto module. You will need to install it:

python -m pip install pycryptodome

[jasonacox]

I'm closing this issue since I haven't heard back. However, please feel free to re-open it if that does not fix your problem:

python -m pip install pycryptodome

Just to point this out. I'm having the exact same issue. Here's a list of installed packages and me running the commands setup.py, scan.py and test.py.

I see that you are running python 3.9 on Windows. Full disclosure, I rarely use windows so there may be a better fix, but in my experience, Windows Python modules get corrupt or mapped wrong. My fix is to always uninstall and reinstall the packages:

C:\Users\jason> pip uninstall pycryptodome
C:\Users\jason> pip uninstall crypto
C:\Users\jason> pip uninstall tuyapower

C:\Users\jason> pip install pycryptodome
C:\Users\jason> pip install tuyapower

C:\Users\jason> python -m tuyapower

[FeikoJoosten]

Thanks for the tip, but I was already a step ahead of you as I had done a reinstall of all of the related modules. Even deleted the pip cache.

[FeikoJoosten]

It also seems that my initial copy paste of the console output did not include the pip freeze command which lists all installed packages.

[jasonacox]

Which versions of python do you have installed? (note: py is a command installed on Window via the python installer)

py -0

My default was set to python 3.7. When I switched to 3.9 the modules were corrupt and I had to reinstall them.

py -m pip uninstall pycryptodome
py -m pip install pycryptodome

Also, make sure you do not have pycrypto installed. It doesn't work well on Windows. This should show the modules you have installed:

py -m piip list

Do you get the same errors with py -m tuyapower ?

[FeikoJoosten]

Ran all of these in the same command promt. I have a feeling I might simply need to add additional modules to my PATH or something?

Which versions of python do you have installed? (note: py is a command installed on Window via the python installer)

Installed Pythons found by py Launcher for Windows
 -3.9-64 *
 -3.8-64
 -2.7-64

My default was set to python 3.7. When I switched to 3.9 the modules were corrupt and I had to reinstall them.

I managed to resolve the issue by renaming the crypto folder in python install/Lib/site-packages from crypto to Crypto!

[jasonacox]

That's great!

It may not matter since you hacked it to work, but looking at the pip list you send the first two modules are corrupt and should not be there. I suspect this could be causing some of the problem as well - it looks like the first was supposed to be "pip" and second one "Crypto" but they got renamed with a "-" prefix:

-ip          20.2.3
-rypto       1.4.1

[FeikoJoosten]

Yeah that could very well be the case. although the Crypto rename issue seems to be something common as I've spotted it multiple times across the interwebs.
