Change availability of a charger or connector

POST 
/chargers/:id/actions/change-availability

Sends an OCPP ChangeAvailability command to mark a charger or specific connector as available or unavailable.

Use Cases:

  • Take chargers offline for maintenance without disconnecting OCPP
  • Reserve connectors for specific users or time periods
  • Implement scheduled availability (e.g., business hours only)
  • Emergency shutdown of problematic chargers
  • Control charger access during grid peak demand events

Availability Types:

  • Operative: Charger/connector available for new sessions
  • Inoperative: Charger/connector unavailable, rejects new sessions (existing sessions may continue)

Command Behavior:

  • Command queued if charger offline, applied on reconnection
  • Affects authorization decisions for new sessions
  • Does not stop active charging sessions
  • Connector-specific or charger-wide availability control
  • Persistent across charger reboots (depends on charger firmware)
info

Use this to mark a charger or connector as available/unavailable. The charger must be online to apply the change immediately, otherwise the command queues until reconnection.

tip

To stop active sessions, use RemoteStopTransaction. ChangeAvailability only prevents new sessions from starting.
