Reset type: Immediate (restart now) or OnIdle (restart when no active transactions)

Optional Fields

evseId integer

If provided, only reset the specified EVSE instead of the entire Charging Station

Example Payload

  "type": "OnIdle"
}

Example Full Frame

Overview

The Reset message instructs the Charging Station to perform a reboot. OCPP 2.0.1 renames the reset types from 1.6J for clarity and adds the ability to reset a single EVSE.

When to Send

After a firmware update to apply changes
When the Charging Station is in an unrecoverable state
For scheduled maintenance reboots

Expected Response

The Charging Station responds with:

status: Accepted, Rejected, or Scheduled

After an Accepted response, the Charging Station will disconnect, reboot, and reconnect with a new BootNotification.

Key Differences from OCPP 1.6J

OCPP 1.6J	OCPP 2.0.1
`type: "Hard"`	`type: "Immediate"`
`type: "Soft"`	`type: "OnIdle"`
Resets entire station	Can target a specific `evseId`

Usage Notes

Immediate: The Charging Station resets as soon as possible, stopping any active transactions
OnIdle: The Charging Station resets when all connectors are idle (no active transactions)
evseId allows resetting a single EVSE without affecting other EVSEs on the same station

Best Practices

Prefer OnIdle in production — Avoids interrupting active charging sessions
Handle the reconnect — After a reset, the Charging Station will reconnect and send BootNotification
Use Immediate only for emergencies — It will terminate active sessions abruptly

Testing Tips

Test Immediate reset and verify the Charging Station reconnects with BootNotification
Test OnIdle while a session is active — station should wait for session to end
Test the Scheduled response scenario (station queues the reset)

Common Errors

`TypeConstraintViolation`

Cause: type is Hard or Soft (from OCPP 1.6J)

Solution: OCPP 2.0.1 uses Immediate (was Hard) and OnIdle (was Soft). Hard/Soft are not valid.

`GenericError`

Cause: evseId specified but EVSE does not support individual reset

Solution: Not all Charging Stations support EVSE-level reset. Check the SupportsNetworkConnectionProfiles variable.
