[FR] Change charge power Passat GTE

I'm owning a Passat GTE (2018-2023 model) and I'm using this integration already with a lot of pleasure to align the charging moments with solar power production. Though I'd like to take it a step further if possible.
In the car there is an option to reduce the charging power. Instead of 2.3/3.5kw it would only use 1kw. I have no idea if it is possible to change this with the API, but if this exists it would be great if it could be added. That way I could even increase self consumation even further.

Is your feature request related to a problem? Please describe.

No

Describe the solution you'd like

Know if it would even be possible over the API, and if so that it would become available in this integration of course

Describe alternatives you've considered

Currently only charging when I have 2.3kw over production.

Additional context

@vlijmen is this option available in the official App?
I have access to two Passat GTEs and the is no option to do Reduce AC Charging in the app.
I can only implement something that is exposed through the APIs.

Unfortunately not (what already annoyed me a bit before I used this integration ;) ). I hoped it would still be available over the API even though the app doesn't offer the option. Guess contacting VW is useless.

Just found out I have two accounts here, one saved on desktop one on mobile, sorry for that.

This is the API response for one of the Passat GTEs that i have access to for the relevant section:

        "chargingSettings": {
            "value": {
                "carCapturedTimestamp": "2024-03-06T10:00:19Z",
                "maxChargeCurrentAC": "invalid"
            }
        },

In case for the feature to work, VW Backend should return something like this:

        "chargingSettings": {
            "value": {
                "carCapturedTimestamp": "2024-03-06T12:08:07Z",
                "maxChargeCurrentAC": "maximum",
                "maxChargeCurrentAC_A": 32
            }
        },

VW theoretically might implement it later on. Till then I can't do anything on my end.

@aphotrax I was checking with two Passat GTEs and I was able to change maxChargeCurrentAC to reduced and maximum.
It seems to be a glitch on the VW side. Maybe invalid status in the case of maxChargeCurrentAC should be considered as valid... 🤣

If you want me to check it with your vehicle as well, please send me your credentials (stickpins at gmail dot com) and your phone number and we will sync via WhatsApp or Signal.

Currently, I don't have confirmation if the change affects the actual charging amperage.

@aphotrax workaround will be available in the next version v4.5.8: #599 (comment)
