UPDATE 31.10.: Amazon Alexa - ioBroker Skill läuft aus ?

[tippy88]

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

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

// file: iobroker/scripts/bmw-cardata-telemetry-autocontainer.js

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)

1. Button control.startAuth auf true.
2. In auth.* erscheinen user_code und verification_uri(_complete).
3. Link öffnen, Code eingeben, BMW-Login bestätigen.
4. 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)

---

8) 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)

// File: script.js.common.Auto.BMW.Streaming

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 :grinning:
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?

Bei mir kommt nix

Edit 15:53: Jetzt kommen auch Daten rein :+1:

[tombox]

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

[Hag-En]

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...!

[michiproep]

Ich bekomm immer folgenden Fehler: hat jemand einen Tipp?

@Steffe-S
das kommt ja nur wenn man auf den Authentifizieren Button klickt. Da kommt bei mir am Fahrzeug auch nichts an. Laut readme braucht es das aber wohl gar nicht:
https://github.com/TA2k/ioBroker.bmw/blob/master/README.md
Ich bekomme tatsächlich einen Fehler nach einer Weile nach der Auswahl des ersten Services. Beim Reload der Seite ist der erstellte Client wieder weg:

Wenn man eine Option auswählt wird der "Client löschen" button ausgegraut. Bei mir wird er mit dem Fehler wieder schwarz. Wenn ich es nochmals versuche und er wird ohne Fehler wieder schwarz denke ich mal sollte er es gefressen haben und man kann das Spiel mit der 2ten Option wiederholen. Bekomme dann aber bei Adapter Start diese Einträge:

@hag-en Danke für die Info

@stenmic Der Code steht im Log vom Adapter. Da steht auch eine URL die man direkt mit Code als Parameter angehängt aufrufen kann - so hat es bei mir zumindest funktioniert.

Stehe auf dem Schlauch. Welcher Adapter? Der alte BMW Adapter? Wo kann ich den Log sehen?
Also mein Log meldet nur den Verbindungsfehler.

[MP_Trixi]

@mp_trixi
finally - ich habs auch hinbekommen. Habe auf der BMW Seite ganz unten einen Reset ausgeführt (kann wohl bis zu 24h dauern bis das gelaufen ist!!) und ohne Fehler nochmals einen Client erstellt (wirklich warten bis der "Client löschen"-Button wieder ohne Fehler Schwarz ist). Dann nochmals die 270 Klicks für den Stream - dann hab ich auch den Adapter zum Starten bekommen.

@McLane
neue Version 4.0.0 von npm oder github
