Get Token - 2878 #117

GSzabados · 2024-11-14T08:10:54Z

Hi,

I have mocked up a script (with the use of ChatGPT) to get the token from an old version (2878) AC.

It can be used from HA terminal like python3 .\ac_2878_get_token.py 192.168.1.100 , just need to include in the same folder the ac14k_m.pem file.

Could you please include it as a file and add some reference to the readme? If you accept this kind of PRs, I will make one then.

        context.load_cert_chain(certfile='ac14k_m.pem')

Thanks so much!!! This worked! After spending 4 days trying to do this, this was so easy!
