Cupra tavascan - incorrect Status B again

[user86000]

Describe the bug

Loadingmode: NotReadyForCharging could be Status A or Status B depending from other values

NotReadyForCharging is A if cable not connected
NotReadyForCharging is B if cable connected, not loading, Car in standby - the mycupra app says "Keine Stromversorgung"

with this
wrong detection "Ladeplan" does not work"

Für dein Issue/PR kannst du es so formulieren:

In Cupra v5, services.charging.status=NotReadyForCharging is ambiguous.
It occurs both when the vehicle is unplugged and when the vehicle is plugged in but the EVSE does not provide power / charging is not enabled. Therefore mapping NotReadyForCharging unconditionally to StatusA or StatusB is unreliable. The vehicle API does not seem to provide a reliable plug state in this payload. If available, plug state should be derived from the charger/EVSE instead, while Cupra should only provide SoC and active charging state.

Solution A:

use a second value from the /v5/users/.../vehicles/.../mycar Endpoint to detect if Status A or B

Solution B:

use the old endpoint /v1/vehicles/{vin}/charging status.plug.connection
to detect Status A, B, C in cobination with
/v5/users/.../vehicles/.../mycar chargignmode

only tested with cupra tavascan software v5.4 but coud be the same one other cupra or other MEB cars

Steps to reproduce
reproduceable by changing from "PV Only" to "Aus"
status is A with cable connected

Steps to reproduce

1. reproduceable by changing from "PV Only" to "Aus"
2. status is A with cable connected

use a second value from the /v5/users/.../vehicles/.../mycar Endpoint to detect if Status A or B

Which value are you referring to? Right now we only have

Status         string
TargetPct      int
ChargeMode     string
ChargeSettings string
Active         bool
RemainingTime  int64
CurrentPct     float64
ProgressBarPct float64

[andig]

"batteryCardStatus": "notConnected",

seems at least brittle since it seems to vanish when connected. We could still use if for "not connected" detection.

[VolkerK62]

what about
Status and ChargeMode
if Status: notReadyForCharging and ChargeMode: off = Status B
