Why is the process dying?

What are the logs (system and steve's) saying?

Thx for reply Julien

Not sure if this is relevant as the time at which the process dies is unknown, but there is an error which indicates

The process killed cause out of memory,

while :; do date; java -jar target/steve.jar; done

Would this workaround work? Also, does charging stop if the vehicle is charging when the process dies?

goekay commented 1 year ago

Also, does charging stop if the vehicle is charging when the process dies?

no. charging stations are autonomous in that regard. they are just notifying steve about transaction start and stop.

which steve version are you using? there has been a memory problem which was fixed recently. see #846 and #1058

Masahirotomoda commented 1 year ago

Hello GoKay

Thx for this ocpp software.

Im using 3.5.0

Im understand this version has memory problem.

and Is this version not supported api?

Should I downgrade my software version?

goekay commented 1 year ago

i actually just made a release which includes the fix and the APIs for 3rd parties

mtomoda commented 1 year ago

It has been 3 days since we installed the new version and the process no longer dies. Thx goekay.

I want to find API usage. Example start remote transaction. Does anyone know of a URL with more information?

juherr commented 1 year ago

@mtomoda see #1000

goekay commented 1 year ago

@mtomoda the capabilities of the API are limited. you cannot start remote transaction via API call. there is no endpoint for this.

mtomoda commented 1 year ago

Thank you reply goekay.

I see I want to start charging by smartphone. Smartphone --- CentralServer(Steve) --- ChargePoint

I believe it is possible to run ChargePoint through Steve from my smartphone via SOAP or WebSocket rather than API. Is there a website that shows how to make this connection?

juherr commented 1 year ago

@mtomoda It will possible when someone will implement it. Maybe a fork already do it but it should be considered like another project.

mtomoda commented 1 year ago

Thx for reply @juherr Ill try it.

goekay commented 1 year ago

closing this issue since it seems to be resolved.
