Where the setting lives
In the charger's web interface, under OCPP settings. You reach it through the charger's own Wi-Fi hotspot (name, password and IP on the label attached to the quick guide; on older units 192.168.1.1) or by Ethernet cable (192.168.0.10). Username and password are also on the label; on older units admin/admin, and newer ones force you to change it on first login.
Step by step
- Connect your phone or laptop to the charger's hotspot (it stays up a few minutes after power-on; you can extend it under Network Settings) and open the IP from the label in the browser. On Android/iOS request the "desktop site".
- Log in with the username and password from the label. The first time it asks you to change the password: write it down.
- OCPP settings → OCPP Connection: Enabled. OCPP Version: 1.6 (the only one).
- Connection Settings: Central System Address = your brand's base URL (below), without the identity; Charge Point ID = the identity you register in the panel (the serial number is the convenient choice). Both are required to save.
- OCPP Configuration Parameters: SecurityProfile = 2 and AuthorizationKey = the password the panel gave you when you added the charger. Leave OCPP Ciphers Support at the standard value.
- Save. Then Network Interfaces → connect the charger to your Wi-Fi or Ethernet, save and reboot. It shows as connected in the panel within a minute.
What to enter to connect it to askacharge.com
| OCPP server URL | wss://askacharge.com/askacharge/ocpp/your-brand — your-brand is your brand's identifier on askacharge.com (shown under Chargers → Add, with the full URL ready to copy). The charger appends its own identity; if your unit only has a URL field and no identity field, enter the full URL: …/ocpp/your-brand/identity. |
| Charge point identity | The same one you register in the panel when adding the charger. Case-sensitive. With Vestel, the serial number is the easiest choice. |
| Username and password | Required. The username is the charger identity and the password is the one the panel shows when you add the charger (shown once; if lost, generate a new one from the charger's page). Without it the server rejects the connection. This is OCPP Security Profile 2 (Basic Auth over wss://); there is no unencrypted or password-less path. |
| Protocol | OCPP 1.6J (JSON) or OCPP 2.0.1. Subprotocol ocpp1.6 / ocpp2.0.1. |
| Before connecting | The charger must be registered in the brand with that identity; otherwise the server rejects the connection. Register under Chargers → Add. |
Where it usually fails
- If any required field is missing the page does not save and does not always say so clearly: check that Central System Address and Charge Point ID are filled before hunting for a network problem.
- To charge without a card from the platform, the FreeModeRFID parameter (
FFFFFFFFin many integrator guides) makes the charger present that virtual card; register it in the panel or authorise by remote start. - Many "branded" chargers (Webasto Unite, among others) are an EVC04 inside: if your web interface is this one, the guide applies whatever the logo says.
If your brand isn't here
The procedure is always the same; what changes is where the setting lives: look in the manufacturer's app, in the charger's web interface (by its IP) or in the installer software for a section called OCPP, Back office, Central System or Server. You need to be able to enter the URL and, nearly always, the identity. If the field is locked or missing, the manufacturer has tied the charger to its own platform: read what to do when the manufacturer locks or switches off its server.
