I have the same problem when using the macOS script to get the Hyundai token. The code is not retrieved after I enter to proceed after the captcha login.

Same here and several issues here: https://github.com/Hyundai-Kia-Connect/hyundai_kia_connect_api

[Roel-GH]

Here the same issue as discribed above.
Does anybody know if there is already a solution available?

[TMA84]

you can test my web app:
https://github.com/TMA84/bluelink-refresh-token

[Roel-GH]

The solution provided above is based om Home Assistant or Docker. I don't have HA or Docker. Is there also a solution via Windows available?

you can test my web app: https://github.com/TMA84/bluelink-refresh-token

@TMA84: I've tested you app and it runs very well. Good work and thank you very much!

I tested several scripts, but only this one worked. I was using the VM in Oracle. When I entered the token in EVCC, it didn't work.
I had to use the “send to EVCC” function. That works perfectly.

https://github.com/TMA84/bluelink-refresh-token

I found another method that doesn’t require Home Assistant. Here’s what I did:

Here https://github.com/TMA84/bluelink-refresh-token, save the data from the standalone folder to your PC.
I saved this to C:\temp and then followed these steps:

1. Copy everything to C:\temp

2. Open cmd

3. Install all dependencies
   pip install flask
   pip install requests
   pip install curl_cffi
   pip install pycryptodome
   pip install pyinstaller

4. Start web.py
   py “C:\temp\web.py”

5. Open the specified address in the browser

• Running on http://127.0.0.1:9876

Now enter your credentials,...

@TMA84: Thank you, I hope that is Ok with that manual

This worked! Thank you very much for your help in this!

Hi @freakezoid1604 & @Roel-GH ,

danke für die Anleitung und das positive Feedback! Freut mich, dass es funktioniert.

Kleiner Tipp: Seit Version 6.1.0 gibt es fertige Standalone-Apps — da brauchst du kein Python mehr installieren:

Windows: BluelinkTokenGenerator.exe — einfach doppelklicken
macOS: BluelinkTokenGenerator-macOS.dmg — öffnen, in Applications ziehen
Linux: BluelinkTokenGenerator-Linux.AppImage — chmod +x, doppelklicken
Download hier: https://github.com/TMA84/bluelink-refresh-token/releases/latest

Gleiche Funktionalität, aber ohne pip install und ohne Python auf dem Rechner. Browser öffnet sich automatisch.

Und ja, natürlich ist das OK — freut mich wenn es anderen hilft! 👍

[freakezoid1604]

Oh Super das ist natürlich noch besser

Sehr, sehr klasse!
