Ahh OK das ging an mir vorbei, sorry. Wie kann ich auf 2.x umsteigen? VG Kilian

OK, hab mir jetzt die sd Karte mit dem Software Update bestellt. Kann ich das als Laie einstecken? Ist der SD Slot leicht zugängig? Ich hoffe ich bekomme das Update hin, liest sich nicht so easy wie erhofft

Einfach Schritt für Schritt der Anleitung folgen. Bei openWB mit Display kommst du leichter an die SD-Karte als bei denen ohne Display (im Netz gibt's viele Bilder zum RPi3-SD-Kartenslot).
Für ev. Fragen beim Umstieg -> Bitte neuen thread aufmachen, um diesen hier nicht zu "verschmutzen".

[Kilian83]

Super, danke.
Nochmal zu diesem topic hier: bei meinen EUP mit EVCC token geht die SOC Abfrage nun wieder, auch bei der alten Software (1.9.304.0 nightly).

Hi,

Kann man, nachdem BMW die Zugriffsberechtigungen geändert hat,
wieder über EVCC Auf den SoC zugreifen ?
In meinem Fall bezieht sich die Frage eigentlich auf MINI.

Hallo,

ist es eigentlich möglich, wenn für einen Hyundai der SoC über EVCC ermittelt wird, neben dem SoC auch die Restreichweite in Kilometer anzeigen zu lassen?

Siehe Bildchen, rechts ohne EVCC für den Born, links mit EVCC für den Hyundai.

Möchte mal nachfragen, keiner in der Runde der den SoC für Hyundai per EVCC ermittelt und neben den SoC auch die Reichweite in Kilometer angezeigt wird?

Ja, dieselbe Frage stelle ich mir auch. Auf der EVCC Seite gibt es für Mini Cardata eine Liste der Attribute, welche im Stream aktiviert sein sollen. Leider gibt es bei Mini nicht alle zum auswählen.
Den Stream habe ich auch aktiviert und dort erhält am separate API Stream Zugangsdaten, die aber im OpenWB EVCC Konfig Feldern nirgends hinterlegt werden können.
Hat es schon jemand zum Laufen gebracht und könnte eine Anleitung posten?

Hallo,

seit ein paar Wochen habe ich keinen SOC mehr für unsern Q4 Etron in der OpenWB.
Integriert per EVCC!

Code: Alles auswählen

Modulmeldung: <class 'Exception'> ('Der SoC kann nicht ausgelesen werden: <_InactiveRpcError of RPC that terminated with:\n\tstatus = StatusCode.UNKNOWN\n\tdetails = "cannot create vehicle type \'template\': cannot create vehicle type \'audi\': IDK form not found"\n\tdebug_error_string = "UNKNOWN:Error received from peer  {created_time:"2026-02-26T11:42:41.966029114+01:00", grpc_status:2, grpc_message:"cannot create vehicle type \\\'template\\\': cannot create vehicle type \\\'audi\\\': IDK form not found"}"\n>. Die Berechnung vom letzten bekannten Soc ist nicht möglich, weil kein Fahrzeug eingesteckt ist.',)

In meinem separatem EVCC auf dem PI wird der SOC aber einwandfrei, mit der aktuellsten EVSS Version, abgefragt.

Kann es sein, dass EVCC noch mal ein Update auf der OpenWB benötigt?

[humschti]

Mach ein Issue im Github von evcc auf. Hinweis auf die openWB nicht vergessen.

[warbird]

Naja, in EVCC direkt läuft es ja, scheint also kein EVCC Problem zu sein. Ich schätze die integrierte EVCC Version ist zu alt.
