Alpha Testing: OCPP Wallbox Adapter

foxriver76

@hardwarefreak habe gerade mal frisch installiert, hast du lokal jetzt was modifiziert gehabt? ich bekomme diese meldung nicht und die validierung sollte nicht anders sein..

und wenn die led auf rot geht steht bestimmt auch was im log, damit könnte ich mehr anfangen.

hardwarefreak

@foxriver76 eigentlich nicht. Bringt es etwas den Adapter noch einmal zu deinstallieren und neu zu installieren?

hardwarefreak

@foxriver76

wenn ich "transactionActive" von "true" auf "false" setze, dann kommt:

und anschließend ist die LED gelb:

und wenn ich dann wieder auf true setze kommt:

foxriver76

@hardwarefreak Sehr komisch, dass da jegliche Validierungen fehlschlagen. Probier mal ne Neuinstallation des Adapters.

Ansonsten mal Ausgabe von npm ls joi in /opt/iobroker

ok ich mache mal eine Neuinstallation.

hardwarefreak

@foxriver76 habe leider immer noch die gleichen Probleme auf meinem Gigabyte Brix unter Proxmox.

Jetzt habe ich das ganze mal auf meinem Tinkerboard installiert und nun bricht die Verbindung nicht mehr ab, wenn ich
"transactionActive" von "true" auf "false" setze und umgekehrt. Parallel läuft auch die piVCCU3 auf dem Tinkerboard.

Die Warnungen bei der Installation sind auf beiden Plattformen identisch.

@foxriver76 am idTag lag es nicht! Anscheind liegt das Problem beim Chargelimit in der RemoteStartTransaction. Wenn das Limit auf 0 gesetzt wird, beginnt er die RemoteStartTransaction mit folgendem Befehl Sending RemoteStartTransaction for /TACW1142021G1020: {"connectorId":1,"idTag":"1"} (ohne das ChargingProfil) und anschließend kann das Ladelimit wieder variabel eingestellt werden. Wird das LadeLimit vor dem Start gesetzt passiert nichts und dieser Befehl wird abgeschickt:
Sending RemoteStartTransaction for /TACW1142021G1020: {"connectorId":1,"idTag":"1","chargingProfile":{"chargingProfileId":1,"stackLevel":0,"chargingProfilePurpose":"TxDefaultProfile","chargingProfileKind":"Recurring","recurrencyKind":"Daily","chargingSchedule":{"duration":86400,"startSchedule":"2013-01-01T00:00Z","chargingRateUnit":"A","chargingSchedulePeriod":[{"startPeriod":0,"limit":6}]}}}

@hardwarefreak
Ich habe auch Probleme mit der Firmware 1.5.2.
Versuch mal dein Chargelimit auf 0 zu setzen und anschließend mit transactionActive=true.
Bei mir sieht das dann so aus und der Ladevorgang kann über umwegen gestartet werden.

Worüber bringe ich dein Script für die PV-Überschussladung zur Ausführung im iobroker?

Das kannst du über Javascript im iobroker ausführen. Du musst dann nur deine Variablen hinterlegen.
Ich kann dir das sonst auch als Blockly-Script zur Verfügung stellen.

Hallo,
bin gerade auch am testen der OCPP Funktionen meiner Wallbox. Es handelt sich um eine M3W von Wallbox24.de welche OCPP 1.6 unterstützt.
Leider funktioniert das setzen des Ladestroms mittels chargeLimit bei mir nicht. Weder zu Begin der Transaktion noch während des Ladens.
Hab dazu mal ein Debug-Log angehängt, wäre echt prima wenn das funktionieren würde dann könnte ich nämlich das PV-Überschussladen angehen.
Das Log zeigt den Start des Ladevorgangs durch Setzen von transactionActive=true mit chargeLimit=6. Wie man in den folgenden Zeilen sieht steigt der Ladestrom dennoch auf über 16A an.
Wenn ich danach das chargeLimit ändere steht im Log nur 'Sending SetChargingProfile for /61689674063277'

alles klar, sowas hatte ich fast befürchtet... Trotzdem vielen Dank für die schnelle Antwort !!!

foxriver76

Ich habe eben eine 0.4.0 veröffentlicht, diese unterstützt nun Authentifizierung. Sprich wenn in den Adapteroptionen Auth aktiviert wird und ein Passwort/Username vergeben wird und ein Client abweichende Credentials bereitstellt, wird die Verbindung abgelehnt.

@schwimbi Hey ich hab auch eine Terra AC, wie hast du alles genau gemacht ?
komme kein Schritt weiter.

thoko

@foxriver76 Zunächst einmal Hochachtung für dein Engagement und diesen Adapter!

Ich verwende zwei Wallboxen Pulsar Plus mit konfiguriertem Power Sharing (Verbindung per CAN).

Testweise habe ich für eine Wallbox eine Instanz OCPP eingerichtet. Nun ist die Wallbox gesperrt (LEDs und auch in der App gelb -> gesperrt). Im Objektbaum wird availability=true, status=Available und transactionActive=true angezeigt.

Ändere ich im Objektbaum transactionActive zunächst auf false und dann wieder auf true, so ändert sich status auf Preparing und die Sperre ist aufgehoben (LEDs und auch in der App grün-> bereit).

Allerdings wird nach 2 Minuten status wieder auf Available gesetzt und die Station ist wieder gesperrt:

@thoko sagte in Alpha Testing: OCPP Wallbox Adapter:

Allerdings wird nach 2 Minuten status wieder auf Available gesetzt und die Station ist wieder gesperrt:

Bei mir ist dieses Verhalten nur wenn aktuell kein Auto angestöpselt ist, passiert das bei dir bei einem aktiven Ladevorgang?

thoko

@foxriver76 Das werde ich gleich mal ausprobieren. Stay tuned :)

thoko

@foxriver76 Wenn ich den Ladestecker einstecke, ändert sich status auf Preparing, aber die Wallbox bleibt blockiert. Erst wenn ich transactionActive erst auf von true auf false und dann wieder auf true setze, ändert sich status über SuspendedEV auf Charging (LEDs und auch in der App grün-> laden).

Ohne OCPP musste ich eben nur den Ladestecker einstecken und konnte direkt laden.

Sehr cool ist aber, dass ich alle 5 Minuten die aktuell geladenen (oder bezogenen?) Wh geliefert bekomme. In der App wird mir das ja erst nach dem Tageswechsel dargestellt.

Natürlich blau, nicht grün.

foxriver76

Ja, mit availability kannst du die Box quasi in den richtigen Lock Zustand setzen, das mache ich z. B. nicht. Wenn die grundsätzlich true ist, kannst du alleine über transactionActive steuern.
