[UI Config] Cannot add OCPP Charger: connector already registered: 1

[aguilaair]

Describe the bug

When adding a Wallbox Commander 2 (FW 6.x), the charger connects to EVCC's OCPP correctly, but then I cannot add it to my dashboard. I get the following error: create failed: cannot create charger type 'template': cannot create charger type 'ocpp': connector already registered: 1

Steps to reproduce

1. Add Charger
2. Select Wallbox FW 6.x
3. Enter station id
4. Click Save, box populates with correct info, popup with error

What type of operating system or environment does evcc run on?

Docker container

External automation

• I have made sure that no external automation like HomeAssistant or Node-RED is active or accessing any of the mentioned devices when this issue occurs.

Nightly build

• I have verified that the issue is reproducible with the latest nightly build

Version

evcc version 0.200.9 (c2f31f1)

When I check the DB, there are no chargers logged in it, so I'm not sure how connector 1 can already be registered

[aguilaair]

Using the evcc config assistant works

[naltatis]

We've addressed similar issues in the last days #19143, #19229.
@andig should OCPP cleanup work right now?

[aguilaair]

Sorry, tried searching the issues but I cannot speak German, so it was a little difficult to find relevant ones.

let me know if you need any other info from me, it is very easily reproducible on my side.

[naltatis]

@aguilaair thanks. I'll come back to you if we can't reproduce.

@mfuchs1984 du bist hier so super im Thema... könntest Du Dir evtl. mal anschauen was es brauchen würde um den Connector erneut registrieren zu lassen? Im Prinzip gibts zwei Möglichkeiten:

• nach dem Context cancel räumen wir alle Konfiguration wieder ab (das bräuchte man wohl für "anonyme" Charger) oder
• wir erlauben einfach, dass bei erneuter Konfiguration die schon bestehenden Strukturen getroffen werden können

Hey, hier auch gleiches Problem mit einer EON vbox bzw Vestel EVC04. Auch nach Werkseinstellung (Hard-Reset) zurücksetzen und evcc komplett Neuinstallation.

[mfuchs1984]

@andig das wird leider zeitlich schwierig, kann also nichts versprechen.

Hey, hier auch gleiches Problem mit einer EON vbox bzw Vestel EVC04. Auch nach Werkseinstellung (Hard-Reset) zurücksetzen und evcc komplett Neuinstallation.

The only way to fix it is to use the .yaml file to configure the chargers

[BastianBayer]

I´m facing the same problem with an Vestel EVC04 that I want to connect via OCPP. Also the the error code: cannot create charger type 'template': cannot create charger type 'ocpp': connector already registered: 1. I run EVCC as add on in Home assistant and did the config of the battery etc. via the experimental UI so if I open up my evcc.yaml the file is empty. How could I manually add the OCPP connection or is there any way to do that ?

[aguilaair]

Easiest way is to use the evcc assistant to generate the .yaml file for you tbh, then you just put that in your empty config file
