Very nice @craiggenner ! Thanks for sharing.

I haven’t had the cookies expire yet. Is that something you experienced?

@imduffy15 Yes, a lot. Varies from 5 to 15 minutes.

@craiggenner bizarre! I haven't updated mine since feb 6th and its going strong.

how do to you get the cookies file? and how do you actually run this? do I need to save in a particular folder?

this is what I get when executing:

➜ python_scripts python alexa_sync.py
Traceback (most recent call last):
File "/homeassistant/python_scripts/alexa_sync.py", line 2, in
import requests
ModuleNotFoundError: No module named 'requests'

Any ideas on what to do, @craiggenner and @imduffy15 ?

you need to install the requests module.

That said this no longer works for me after a change at Amazons end.

@craiggenner what a shame :(. We need to find a way for this work. I will research and circle back to you guys.

Any news? Did someone manage to fix it?

did anyone find a fix for this?
