Remote Start Transaction Energy limit
Hello, Is it possible to send to the OCCP client using the RemoteStartTransaction the energy value, after which the charger will automatically stop charging?
ocpp spec defines it, so... yes. but it is not implemented in steve yet. it is a little bit more involved than just sending an energy value, though. ocpp spec uses the term charging profile, which fully describes the time periods, charing rates and other details of charging sessions.
do you plan to extend the system with such functionality? I think that this is a very interesting possibility to send a charging profile to the charger, on the basis of which the charger would automatically finish loading.

i remember this operation being cumbersome to implement, which is why i left it out initially. i can look into it when i have time.
... possibility to send a charging profile to the charger
this is already possible, but in a slightly verbose way, i guess. after remote start tansaction, the station should send a Start Transaction message. during a transaction you can use the operation Set Charging Profile to control the charging behaviour.
@daniel8702 @goekay ,
l want transaction id xxxxx to stop after charging xxxx KW or a hack around it.
{ "connectorId": 0, "idTag": "xxxxxxxxxxxx", "chargingProfile": { "chargingProfileId": 10, "transactionId": null, "stackLevel": 0, "chargingProfilePurpose": "TxProfile", "chargingProfileKind": "Relative", "recurrencyKind": "Daily", "validFrom": "2022-02-18T10:18:46.000Z", "validTo": "2022-08-18T10:18:46.000Z", "chargingSchedule": { "duration": 4200, "startSchedule": "2022-08-18T10:18:46.000Z", "chargingRateUnit": "W", "chargingSchedulePeriod": [ { "startPeriod": 0, "limit": 50 }, { "startPeriod": 120, "limit": 0 } ] } } }
will setting the last value to zero work
