Test Adapter BMW/Mini v4.x.x

stenmic

@tombox hab eben die neuste Version von git getestet. Funktioniert nicht mehr.
Jemand müsste den Adapter auf BMW CarData umbauen.

lobomau

@stenmic @tombox nichts zu machen. Habe auch aktualisiert. Und auch

Session found. If the login fails please delete bmw.0.auth.session and restart the adapter

beachtet. Aber es bleibt dabei:

@lobomau Ok ja bmw hat ihre App API mit approov abgesichert. Das heißt die API kann nur noch von einem echten Android oder iPhone abgesendet werden.
https://approov.io/customer/bmw/

Es bleibt wirklich nur wie von BMW angekündigt der weg über CarData

Aber dieser ist begrenzt auf ready only und damit gibt es auch noch Probleme.
Mir fehlt aber gerade die Zeit um das umzusetzen. Ich probiere mal die Tage ob KI das die Tage schnell runterprogrammieren kann

Besser wäre es aber auf HA zu wechseln

echt jetzt !

Wir verweisen hier bewusst auf HA ?

stenmic

@bahnuhr das dachte ich leider auch.
Am Ende nutze ich wahrscheinlich nur noch die VIS (1)

VIS (1)

Na klar, was sonst.

Vis 2 hat noch zu viele Fehler.
Und, ich müsste alles neu machen.

tippy88

Ich habe mit Code Copilot zwei Scripte gebaut, damit funktioniert die BMW Integration.

Verbindung zu BMW CarData und auto-refresh der Tokens vor Ablauf. Kann ebenso Daten über die CarAPI abrufen welche auf 50 Calls pro Tag begrenzt ist.
Script baut eine MQTT Verbindung zum Car Streaming auf. refreshed die Verbindung wenn der ID_Token nach 1h abläuft. Schreibt alle Daten in separate DP.

Zusätzliche binde ich die CarStream daten an die entsprechende DP des BMW adapters. Dies ist nur nötig bis EVCC auf den Carstream umgestellt hat, aber so bekommt EVCC inzwischen die Live Daten.

Der CarStream liefert tatsächlich annährend Live Daten. Auf der Fahr in die Arbeit heute morgen wurde mindestens jede Minute der SOC, restkiliometer etc aktualisert.

Ich kann heute Abend nach der Arbeit gerne die Scripte teilen und versuchen eine Kurze Anleitung dazu zu schreiben.

Das wäre ein Traum, ich leide auch darunter, dass BMW hier wenig kundenfreundlich agiert hat.

Vorab:
Ich bin kein Entwickler, das hat AI auf meine Anweisungen programmiert. Ich übernehme keine Verantwortung für die vollständige Funktion. Bei mir läuft es und ich habe damit MEIN Ziel erreicht. Beim ersten Start werden evtl viele Error geloggt wenn die States erstmalig angelegt werden.
Alle Daten landen in: 0_userdata.0.Auto.BMW (anpassbar im Script)

Also Voraussetzung sollte man für sein Fahrzeug bei BMW schonmal die Cardata und Streaming aktivieren, sowie beim Streaming die entsprechenden Datenpunkte aktivieren:

[Anleitung] BMW CarData in ioBroker: basicData & telematicData (mit Auto-Container) + Telegram

1) Voraussetzungen

Adapter javascript (z. B. javascript.0)
BMW Konto mit Fahrzeug in MyBMW verknüpft
(Optional) Telegram: Instanz telegram.0

2) Script importieren

In ioBroker → Skripte → Neues JavaScript anlegen.
Den bereitgestellten Code vollständig einfügen (bmw-cardata-telemetry-autocontainer.js).
Speichern & Starten.
Code:

Persönliche Daten werden nicht im Code, sondern als States gepflegt.

3) Konfiguration (States setzen)

Alle States unter: 0_userdata.0.Auto.BMW

OAuth / BMW

config.client_id → <CLIENT_ID>
config.scope → authenticate_user openid cardata:api:read carstream:api:read

API

config.api_base_url → https://api-cardata.bmwgroup.com
config.api_version → v1
config.accept_language → z. B. de-DE
config.refresh_send_scope → true (empfohlen)

Fahrzeug & Telematik

data.selected_vin → <VIN> (z. B. WBY61EF0405W24607)
Container
- config.container_id → leer lassen für Auto-Erstellung oder vorhandene ID eintragen
- config.container_auto_create → true (Default)
- config.container_name → ChargeStats (frei wählbar)
- config.container_purpose → ioBroker (frei wählbar)
- config.container_descriptors → JSON-Array der Technical Descriptors, z. B.:
```
[
  "vehicle.drivetrain.electricEngine.charging.level",
  "vehicle.drivetrain.electricEngine.kombiRemainingElectricRange",
  "vehicle.vehicle.travelledDistance",
  "vehicle.body.chargingPort.status"
]
```

(Optional) Telegram

notify.telegram_enabled → true
notify.telegram_instance → telegram.0
notify.token_warn_minutes → 10
notify.on_auth / notify.on_refresh_fail / notify.on_fetch_fail / notify.on_scope_warning / notify.on_container_events → nach Wunsch true

4) Erst-Authentifizierung (Device Code)

Button control.startAuth auf true.
In auth.* erscheinen user_code und verification_uri(_complete).
Link öffnen, Code eingeben, BMW-Login bestätigen.
auth.status = authorized, Tokens unter tokens.*.

Wichtig: Der User-Code-Schritt ist nicht automatisierbar (BMW-Policy). Token-Refresh läuft danach automatisch.

5) Daten abrufen

A) basicData

Button control.fetchBasicData.
Ergebnis:
- JSON: …data.<VIN>.basicData

B) telematicData (Auto-Container & Abfrage)

Falls config.container_id leer und config.container_auto_create=true:
→ Script ruft POST /customers/containers auf, speichert Antwort nach
…data.<VIN>.containers.<CONTAINER_ID>.meta und trägt config.container_id automatisch ein.
Button control.fetchTelematicData.
Ergebnisse:
- Roh-JSON: …data.<VIN>.telematicData.<CONTAINER_ID>
- Flache Einzel-Datenpunkte (+ _unit, _ts) unter:
  …data.<VIN>.telemetry.<CONTAINER_ID>.<ATTRIBUT>
- Beispiel:
  - …telemetry.S00W005P177MV.vehicle_drivetrain_electricEngine_charging_level → 61
  - …telemetry.S00W005P177MV.vehicle_drivetrain_electricEngine_kombiRemainingElectricRange → 244

Scope-Hinweis: Für telematicData ist carstream:api:read erforderlich – sonst 403.

6) Optional: Automatisierung

Per Zeitplan (CRON) oder kleinem Trigger-Skript regelmäßig (max 50 Aufrufe pro TAG!):
- control.fetchTelematicData (z. B. alle 30 Min)
- control.fetchBasicData (z. B. 1× täglich)

Beispiel (einfacher, separater JavaScript-Cron-Trigger):

schedule('*/10 * * * *', () => setState('0_userdata.0.Auto.BMW.control.fetchTelematicData', true));
schedule('0 3 * * *', () => setState('0_userdata.0.Auto.BMW.control.fetchBasicData', true));

7) Datenpunkte (Kurzüberblick)

auth.* – Status, Code, Verifizierungs-URL, Warnungen
tokens.* – access_token, refresh_token, Ablaufzeiten, optional id_token + Claims
config.* – Client/Scope/API/Container-Optionen
control.* – Buttons (startAuth, refreshNow, fetchBasicData, fetchTelematicData, createContainer)
data.*
- Diagnose: last_url, last_status, last_headers_json, last_response, last_error
- Fahrzeug: data.<VIN>.basicData
- Container-Meta: data.<VIN>.containers.<CONTAINER_ID>.meta
- Telemetrie (Roh): data.<VIN>.telematicData.<CONTAINER_ID>
- Telemetrie (flach): data.<VIN>.telemetry.<CONTAINER_ID>.* (+ _unit, _ts)

Fehler & Troubleshooting

403 (CU-403): Scope/Headers/VIN/Container prüfen. Für Telemetrie carstream:api:read muss im Token enthalten sein → ggf. config.scope setzen und neu autorisieren (control.startAuth).
401: Access-Token abgelaufen → Script refresht automatisch; bei Refresh-Fehler Telegram-Hinweis (falls aktiv) und neu autorisieren.
Leere DPs: Script nutzt atomare Writes; prüfe data.last_error & data.last_response.
Container nicht erstellt: config.container_descriptors muss gültiges JSON-Array sein. Ansonsten control.createContainer drücken und Logs prüfen.

9) Sicherheit & Datenschutz

Tokens nie veröffentlichen (auch nicht gekürzt).
Screens/Logs fürs Forum anonymisieren (<CLIENT_ID>, <VIN>, <CONTAINER_ID>).
ioBroker-Admin absichern.

10) Platzhalter (nur in States setzen)

<CLIENT_ID> → config.client_id
<VIN> → data.selected_vin
<CONTAINER_ID> → config.container_id (leer lassen für Auto-Erstellung)

[Anleitung] BMW Car Streaming via MQTT.

1) Voraussetzungen

Token-Flow existiert & aktualisiert 0_userdata.0.Auto.BMW.tokens.id_token.
BMW MQTT Zugangsdaten aus Portal:
- Host: customer.streaming-cardata.bmwgroup.com
- Port: (bei Dir z. B.) 9000
- Username: Deine GCID aus BMW portal unter Cardata Streaming (GUID, z. B. c4beb4…8916)
- Topic: <username>/<VIN> (z. B. c4beb4…8916/WBY61EF0405W24607)
ioBroker JavaScript-Adapter aktiv.

2) `mqtt` installieren (einmalig)

*In der Javascript Instanz wo das Script laufen soll, unter Settings, als zusätzliches NPM Modul mqtt eintragen.

3) Script anlegen

In Admin → Skripte → JavaScript → Neu → Datei z. B. script.js.common.Auto.BMW.Streaming.
CFG unten (Host/Port/Username/VIN) auf Deine Werte setzen.

4) Script (Copy & Paste)

5) Start & prüfen

Daten setzen:
- username: '0_userdata.0.Auto.BMW.streaming.config.username'
- vin: '0_userdata.0.Auto.BMW.streaming.config.vin',
Log:
- Connected to BMW MQTT
- Subscribed → Topic sollte <username>/<VIN> anzeigen.
- Bei Daten: RX { topic: ..., bytes: N }
Objects → 0_userdata.0.Auto.BMW.streaming.<VIN>:
- connected = true, subscribed = <username>/<VIN>
- Bei Daten: lastJson, lastEventTime, fields.*, metrics.range_km
- health.lastRxAgoSec ≈ 0–15, steigt laufend ohne Daten.

Troubleshooting (kurz)

Subscribe error: Not authorized → falscher Topic-Filter. Nur <username>/<VIN> abonnieren (keine Wildcards).
invalid password im lokalen mqtt.x-Adapter → Du verbindest versehentlich zu Deinem lokalen Broker. Stelle sicher, dass die URL mqtts://customer.streaming-cardata.bmwgroup.com:9000 ist.
Keine Daten, aber connected → oft Portal-Thema (VIN/Descriptors/Region). Teste Fahrten, Start/Stop Laden, Klima.
Quota exceeded → Script wartet automatisch (quotaCooldownMs) und verbindet dann wieder.
Einzel-Session → Script macht sauberen DISCONNECT bei Stop/Re-Auth. Keine Doppelverbindungen.

HINWEIS

Wenn ihr MQTT Streaming verwendet, braucht ihr TelematicData überhaupt nicht abrufen. Alle im BMW portal gewählten Daten kommen dann automatisch über den Stream, allerdings nur bei Änderung. Steht das Auto still und nichts verändert sich, kommen keine Daten.
Die API selber läuft auch nicht 100% sauber, der BMW support schreibt selbst: "aktuell haben wir Probleme mit unseren CarData Customer Client / API / Streaming Lösungen.
Unsere Entwickler arbeiten mit Hochdruck an der Beseitigung der Störung - zusammen mit den Partnersystemen."
Nichtdestotrotz, bei mir läuft es aktuell.

@bahnuhr sagte in Test Adapter BMW/Mini v2.0.0:

echt jetzt !

Was erwartest denn? Ich bekomm seit gefühlt zwei Jahren kaum noch Adapterupdates und immer mehr funktioniert nicht mehr. Dann kommen noch so Userunfreundliche Dinge wie VIS 1 auf 2 dazu.

Diese Bild sagt eigentlich alles... Schade, ich nutze iob gern, aber irgendwann wird man wechseln "müssen"

@lobomau Die KI hat den Adapter geupdated aber bisher konnte ich nicht intensiv testen

Danke. Wie werden die 2 Wochen Lifetime des User-Code gehandelt, dann auch manuell alle 2 Woche neu autorisieren?
Ich werde den Adapter dann auch mal testen.

@tippy88
ich habe mir den 4.0.0 auch mal gezogen. Allerdings bin ich zu blöd den den CarData Client zu erstellen. Ich habe mir schon nen Ast abgesucht. Die Doku zur API habe ich gefunden: https://bmw-cardata.bmwgroup.com/customer/public/api-documentation/Id-Technical-registration_Step-1
Aber mit den Links dort komm ich nicht ans Ziel. Wie es im Adapter steht, gehts auch nicht. Bei https://customer.bmwgroup.com bekomme ich 404 (Seite nicht gefunden)
Das "customer portal" von dem die Reden ist BMW ConnectedDrive. Da sehe ich oben mein Fahrzeug und kann Pakete nachkaufen. Aber nichts von CarData weit und breit.

tippy88

@mp_trixi BMW.de, Einloggen und dann das Fahrzeug auswählen:

MP_Trixi

@tippy88
danke - hat geholfen
muss man hier die beiden Optionen auswählen und dann noch auf Client Authentifizieren?

Steffe.S.

@mp_trixi

Zeigt das Display des Fahrzeugs etwas an, da soll ein Code erscheinen?

Screenshot 2025-10-01 132316.png

Bei mir kommt nix

Edit 15:53: Jetzt kommen auch Daten rein

tombox

@steffe-s bitte readme folgen und die client id bei iobroker Einstellungen einfügen

Mal ein Feedback von mir:

Die Kopplung mit cardata funktioniert, ich bekomme Streaming-Daten...!

Wirklich toll, dass in so kurzer Zeit eine sehr funktionsfähige Lösung bereitgestellt wurde - Respekt und danke dafür...!
