Changing to Secure WebSocket Connectivity
 

By default, chargers migrated via OCPP (Option B in section 1) connect to Eve Control using an insecure WebSocket connection (ws://). To upgrade to a secure connection (wss://), you need to perform a security firmware update that installs the required TLS root certificate and updates the OCPP connection URL.

1 Verify the Charger is Online
Navigate to Charging Stations and confirm that the charger you want to update is online and connected to Eve Control.

2 Initiate the Security Firmware Update
Open the charger’s detail page and navigate to the Firmware tab. Start the security firmware update. This update installs the root certificate required for TLS and reconfigures the charger’s OCPP connection from ws://ocpp.alfen.com/ to wss://ocpp.alfen.com/.

3 Wait for the Update to Complete
The charger will download and apply the security firmware update, then reboot automatically. After the reboot, it will reconnect to Eve Control using the secure wss:// connection.

4 Verify the Secure Connection
Once the charger is back online, confirm that the connection is now using wss://. You can verify this in the charger’s Logging tab or configuration details.
