In order to send a command to a charger first navigate to the specific charger. You can find it by using the search filters on the Chargers overview page. When you have found it click on it to go to the Charger detail page.
On the Charger detail page navigate to the Commands tab.
Here you can find OCPP commands that are used most often. The commands that are not visible in the Portal can still be used through our API.
Below you will find a short description for each command:
- Reset
OCPP supports two kinds of Reset, hard and soft. A soft reset will still give time to the charger to finish the running session (when applicable) after which it will reset. A hard reset is more forceful and is usually used as a last resort to reset a charger that is malfunctioning.
- TriggerMessage
A TriggerMessage command can request the charger to send messages again that have already been sent. For instance the
BootNotification, DiagnosticsStatusNotification, FirmwareStatusNotification, Heartbeat, MeterValues and the StatusNotification.
- UnlockConnector
This command is used to unlock a connector. Usually an EV driver calls to ask if an operator can help by unlocking the connector remotely in case of a malfunction.
- ChangeAvailability
This command can be used to change the status of a connector or charger (when connector id 0 is used) remotely. A common use case for this command is when a charger will receive maintenance and it has to be set to unavailable for a short period of time.
- Configuration
By means of the Configuration command a technical configuration setting can be remotely edited.
Note: Only use this command if you know what you are doing!
- RemoteStart
The RemoteStart is used to remotely start a session. In order for this to work you will need to provide a valid charge token. Usually used by mobile apps to start a session.
- RemoteStop
The RemoteStop is used to remotely stop a running session. The transaction id of the running session should be provided for this to work. Similar to the RemoteStart, this command is usually used by mobile apps to to stop a session. Another scenario to use this command is when a charger is in error but you still want to stop a running session.
- GetDiagnostics
This command is used to request the charger to send its technical data to a specified (ftp) destination.
Note: Only use this command if you know what you are doing!
- Update Firmware
The UpdateFirmware command is used to update the current firmware with a newer version. It is possible to specify a date and time to execute this update. For instance during the night when there are no running charging session.
Note: Only use this command if you know what you are doing!
