Common patterns
| Symptom | First check |
|---|---|
| Charger offline | Connectivity — modem signal, network outage, recent firmware update. |
| Session fails to start | Authorization — token expired, tariff missing, roaming token rejected. |
| Session ends prematurely | Charger faults, EV signals stop, OCPP StopTransaction reason. |
| Wrong kWh on CDR | Meter rollover, calibration drift — pull the meter-value timeline. |
Remote actions
- Reset — soft or hard reset the charger.
- Reboot — full power cycle (only some chargers support this remotely).
- Change availability — take an EVSE out of service.
- Trigger message — ask the charger to push current status.
