Is there any "PR" or custom code for the Renault 4 E-tech to get access to all available informations of the car ?

Did you look at #1747

[Pierre-Lavoine]

Yes I did, and nothing listed for Renault 4 E-tech

Hi,

I try to use your API and here is some result about "GET" information, I will do the "ACTIONS" later today
@epenet Let me know if it's a good start or if you need more information

✅ Working endpoints (OK)

Battery status (v2)

GET /commerce/v1/accounts/{account_id}/kamereon/kca/car-adapter/v2/cars/{vin}/battery-status

Returns expected fields (example): batteryLevel, batteryAutonomy, plugStatus, chargingStatus, chargingRemainingTime, timestamp.

HVAC status (v1)

GET /commerce/v1/accounts/{account_id}/kamereon/kca/car-adapter/v1/cars/{vin}/hvac-status

Returns (example): hvacStatus, socThreshold, internalTemperature, lastUpdateTime.

Location (v1)

GET /commerce/v1/accounts/{account_id}/kamereon/kca/car-adapter/v1/cars/{vin}/location

Returns (example): gpsLatitude, gpsLongitude, lastUpdateTime.

Cockpit (important: v1 works, v2 does not)

✅ Works:
GET /commerce/v1/accounts/{account_id}/kamereon/kca/car-adapter/v1/cars/{vin}/cockpit

Example response:

{
"data": {
"attributes": {
"totalMileage": 5892,
"timestamp": "2026-01-23T08:49:13Z",
"fuelQuantity": 0.0
}
}
}

❌ v2 is blocked / unexpected:
GET /commerce/v1/accounts/{account_id}/kamereon/kca/car-adapter/v2/cars/{vin}/cockpit
returns:
{"message": "you should not be there but well done for the effort"}

KCM EV settings (v1)
GET /commerce/v1/accounts/{account_id}/kamereon/kcm/v1/vehicles/{vin}/ev/settings
Returns schedules / charge mode request / preconditioning settings, etc.

Charges list (v1) – requires ISO UTC start/end

Base endpoint:
GET /commerce/v1/accounts/{account_id}/kamereon/kca/car-adapter/v1/cars/{vin}/charges

Calling without query params returns:
err.func.wired.missingRequestParam: must be present

✅ Working form (UTC ISO 8601 with Z):
GET .../charges?start=YYYY-MM-DDT00:00:00Z&end=YYYY-MM-DDT23:59:59Z

Example:
.../charges?start=2026-01-01T00:00:00Z&end=2026-01-23T23:59:59Z

This returns an array of charge sessions (example fields):
chargeStartDate, chargeEndDate, chargeStartBatteryLevel, chargeEndBatteryLevel, chargeEnergyRecovered, chargeDuration, chargeEndStatus.

❌ Not available (URL does not exist) on this model

These return:
err.func.wired.not-found: The specified url does not exist

GET /commerce/v1/accounts/{account_id}/kamereon/vehicles/{vin}/alerts
GET /commerce/v1/accounts/{account_id}/kamereon/kca/car-adapter/v1/cars/{vin}/charge-history
GET /commerce/v1/accounts/{account_id}/kamereon/kca/car-adapter/v1/cars/{vin}/hvac-history
GET /commerce/v1/accounts/{account_id}/kamereon/kca/car-adapter/v1/cars/{vin}/hvac-sessions
GET /commerce/v1/accounts/{account_id}/kamereon/kcm/v1/vehicles/{vin}/ev/soc-level

❌ Forbidden (403) on this model/account

These return:
err.func.wired.forbidden: The access is forbidden

GET /commerce/v1/accounts/{account_id}/kamereon/kca/car-adapter/v1/cars/{vin}/charge-mode
GET /commerce/v1/accounts/{account_id}/kamereon/kca/car-adapter/v1/cars/{vin}/charge-schedule
GET /commerce/v1/accounts/{account_id}/kamereon/kca/car-adapter/v1/cars/{vin}/charging-settings

❌ “No data for this vin and uid” (404) – likely unsupported telemetry

These return:
errorCode 404: There is no data for this vin and uid

GET /commerce/v1/accounts/{account_id}/kamereon/kca/car-adapter/v1/cars/{vin}/lock-status
GET /commerce/v1/accounts/{account_id}/kamereon/kca/car-adapter/v1/cars/{vin}/pressure
---(Which is actually strange since my car is abble to say if my pressure is low)
GET /commerce/v1/accounts/{account_id}/kamereon/kca/car-adapter/v1/cars/{vin}/res-state

❌ Gateway mismatch (functional)

GET /commerce/v1/accounts/{account_id}/kamereon/kca/car-adapter/v1/cars/{vin}/notification-settings

Returns:
errorCode 400001: The vehicle does not have a GDC gateway

⚠️ Server-side technical error (intermittent?)

GET /commerce/v1/accounts/{account_id}/kamereon/kca/car-adapter/v1/cars/{vin}/hvac-settings

Returns:
errorCode 502000: something went wrong (technical)

@epenet Here is actions test

Action endpoints test report – Renault R4 E-Tech (model A4E1VE)

Vehicle

• Brand/Model: Renault R4 E-Tech
• Model code: A4E1VE (not documented in renault-api, defaults used)
• VIN: {vin} (redacted)
• Account: {account_id} (redacted)

Context

• Tests executed with renault-api CLI inside Docker (python:3.12-slim).
• Date: 2026-01-23
• Note: renault-api http supports get and post only (no put command in this CLI build).

Summary:
✅ Remote horn and lights work.
✅ Remote HVAC start/cancel works (status updates with slight delay).
❌ All charge remote control actions are blocked or malformed:
charging-start: forbidden
charging-stop: invalid-body-format
pause/resume (KCM): forbidden
charge-mode action: invalid-body
schedules: forbidden
Model A4E1VE is not documented in the library (defaults used).

✅ Working actions

1) Horn / Lights (KCA)

Endpoint:
POST /commerce/v1/accounts/{account_id}/kamereon/kca/car-adapter/v1/cars/{vin}/actions/horn-lights

Horn payload (works):

{"data":{"type":"HornLights","attributes":{"action":"start","target":"horn"}}}

Lights payload (works – position lights blink):

{"data":{"type":"HornLights","attributes":{"action":"start","target":"lights"}}}

API returns an action id for both, and the vehicle executes them.

HVAC start / cancel (KCA)

Endpoint:
POST /commerce/v1/accounts/{account_id}/kamereon/kca/car-adapter/v1/cars/{vin}/actions/hvac-start

Start payload (works):

{"data":{"type":"HvacStart","attributes":{"action":"start","targetTemperature":21.0}}}

{"data":{"type":"HvacStart","attributes":{"action":"cancel"}}}

Verification:
GET .../hvac-status switches hvacStatus from on to off with ~30–60s telemetry delay.

❌ Charge-related actions (not working / not allowed)
3) Charging start (KCA)

Endpoint:
POST /commerce/v1/accounts/{account_id}/kamereon/kca/car-adapter/v1/cars/{vin}/actions/charging-start

Start payload:

{"data":{"type":"ChargingStart","attributes":{"action":"start"}}}

Result: ❌ err.func.wired.forbidden ("The access is forbidden")

Stop payload:

{"data":{"type":"ChargingStart","attributes":{"action":"stop"}}}

Result: ❌ err.func.wired.invalid-body-format ("Body has at least one wrongly formatted value")

Even while the vehicle is charging:
GET .../battery-status shows plugStatus=1 and chargingStatus=1.0

KCM pause/resume (while charging)

Endpoint:
POST /commerce/v1/accounts/{account_id}/kamereon/kcm/v1/vehicles/{vin}/charge/pause-resume

Pause payload:
{"data":{"type":"ChargePauseResume","attributes":{"action":"pause"}}}
Resume payload:
{"data":{"type":"ChargePauseResume","attributes":{"action":"resume"}}}
Result: ❌ both return err.func.wired.forbidden ("The access is forbidden") even when chargingStatus=1.0

Charge mode action (KCA)

Endpoint:
POST /commerce/v1/accounts/{account_id}/kamereon/kca/car-adapter/v1/cars/{vin}/actions/charge-mode

All tested bodies return:
❌ err.func.wired.invalid-body ("Body is missing or cannot be bound")

Examples tried:

{"data":{"type":"ChargeMode","attributes":{"action":"always"}}}
{"data":{"type":"ChargeMode","attributes":{"action":"scheduled"}}}
{"data":{"type":"ChargeMode","attributes":{"chargeMode":"always"}}}
{"data":{"type":"ChargeMode","attributes":{"chargeMode":"scheduled"}}}

Conclusion: endpoint reachable but request body cannot be bound on this backend/model.

Schedule actions (KCA v2)

Charge schedule:
POST /commerce/v1/accounts/{account_id}/kamereon/kca/car-adapter/v2/cars/{vin}/actions/charge-schedule
Result: ❌ err.func.wired.forbidden

HVAC schedule:
POST /commerce/v1/accounts/{account_id}/kamereon/kca/car-adapter/v2/cars/{vin}/actions/hvac-schedule
Result: ❌ err.func.wired.forbidden

CLI charge stop/start

renault-api charge stop → ❌ err.func.wired.invalid-body-format
