EU (>2023) controls - how to help get working?

[badnbusy]

I work in IT and am a systems engineer/developer.

How can I help in getting the newer cars EU (>2023) controls working like Climate, Seat Controls, Charge Start/Stop, Open/Close Windows etc?

According to the docs, these controls are possible on pre 2023 models so what has changed?

How can I help in figuring out the API calls/endpoints used so I can contribute back to the codebase?

I have a Hyundai Kona EV 2024 (UK).

Thanks

Have you tested and they don't work? My understanding is they do work.

They don't seem to do anything and checking in Bluelink they haven't turned on the AC or whatever set on the options...

HA log when performing the Climate enable option:

The action thing seems to be an ongoing item but shouldn't impact the first call. Climate start is very dependent on the options sent.

If you sniff the traffic from the native app you can compare the payload to see what it didn't work.

[badnbusy]

Ok, will do.

It will all be HTTPS so assuming some MITM proxy required here and a 3rd party CA cert on Android etc.

Tried Charles Proxy but the app refuses to connect with that even when SSL proxying is enabled.

Will go down the Android emulator route, with root access to install System CA certs and the app.

That's the right path. Certificate pinning is implemented as well which makes it harder. I have heard Android 6 helps getting around this. The blue linky discord has talked about this too. I don't live in eu so personally haven't needed to do this much. Canada is easier to sniff.
