/tx/statusGET

The transaction status topic contains information about an ongoing charging transaction.

id - String - UUID of the charging transaction.
state - String - State of the SECC
- IDLE - No EV connected.
- AWAITING_START - An EV is connected and the EVSE is waiting for a start transaction.
- AWAITING_AUTHORIZATION - An EV is connected and the EVSE is waiting for an authorization.
- STARTING - An EV is connected and the EVSE is starting the charging session.
- SUSPENDED_EVSE - Charging is suspended by the EVSE.
- SUSPENDED_EV - The charging is suspended by the electric vehicle.
- CHARGING - The EV is being charged.
- FAILED - The EVSE is in an error state.
- STOPPED - An EV is connected and charging is stopped.
- LINGERING - An EV is currently connected or was recently connected and the EVSE is still in the same transaction.
- COMPLETED - Charging is completed, EV is not connected, EVSE is available.
effectiveAmperageLimit - float - EffectiveAmperageLimit - absolute amperage limit of the EVSE, due to cable cross section of the installation or the cable between the EVSE and the EV.
startedTime - float - Time when the EVSE started charging.
endedTime - float - Time when the EVSE stopped charging.
startReason - String - Reason why the charging was started.
- Authorized - Charging is authorized, by any means. Might be an RFID, or other authorization means.
- CablePluggedIn - Cable is plugged in and EVDetected.
- ChargingRateChanged - Rate of charging changed by more than LimitChangeSignificance.
- ChargingStateChanged - Charging State changed.
- Deauthorized - The transaction was stopped because of the authorization status in the response to a transactionEventRequest.
- EnergyLimitReached - Maximum energy of charging reached. For example: in a pre-paid charging solution.
- EVCommunicationLost - Communication with EV lost, for example: cable disconnected.
- EVConnectTimeout - EV not connected before the connection has timed out.
- MeterValueClock - Needed to send a clock aligned meter value.
- MeterValuePeriodic - Needed to send a periodic meter value.
- TimeLimitReached - Maximum time of charging reached. For example: in a pre-paid charging solution.
- Trigger - Requested by the CSMS via a TriggerMessageRequest.
- UnlockCommand - CSMS sent an Unlock Connector command.
- StopAuthorized - An EV Driver has been authorized to stop charging. For example: By swiping an RFID card.
- EVDeparted - EV departed. For example: When a departing EV triggers a parking bay detector.
- EVDetected - EV detected. For example: When an arriving EV triggers a parking bay detector.
- RemoteStop - A RequestStopTransactionRequest has been sent.
- RemoteStart - A RequestStartTransactionRequest has been sent.
- AbnormalCondition - An abnormal error or a fault condition has occurred.
- SignedDataReceived - Signed data is received from the energy meter.
- ResetCommand - CSMS sent a Reset Charging Station command.
energyActiveImportRegister - Represents the cumulative active energy imported by the EVSE
lastActivePower - float - Current active power of the EVSE.
meterStart - float - Value of the energyMeter at the start of the session.
meterStop - float - Value of the energyMeter at the end of the session.
peakPhaseAmperage - array - Peak amperage values for each phase of the EVSE.
peakActivePower - float - Peak active power of the EVSE.
