How to change the OCPP server URL on a Circutor charger

The Circutor URBAN is common in public car parks, hotels and campsites in Spain, and many have been left without a platform when their previous network dropped them. It speaks standard OCPP, so it moves to another one by changing a few settings in its local web page. Guide built from Circutor's and integrators' documentation and from the answers of Circutor's technical service (October 2026). The surprise: the URBAN only speaks ws://, unencrypted, and has no username or password fields. askacharge.com accepts it anyway, charger by charger.

Where the setting lives

In the charger's own configuration web page, opened with a browser from a computer on the same network. http://<IP>/ for network and integrations, and http://<IP>:8080/html/setup.html for the OCPP settings (username admin, password 1234 from the factory). There is no app or cloud portal: everything is done locally.

Step by step

  1. Check the side label: model, code (V10623 for the URBAN T22) and serial number. If the front says Designed by Circontrol, it is the newer generation, with OCPP 1.6J and the same web page as the Circontrol eNext and Raption; URBAN units from 2017-2019 may need new firmware.
  2. Add the charger on askacharge.com with the serial number as its identity (all together, no spaces) and keep the password the panel shows you.
  3. Connect a laptop to the same network as the post. The URBAN ships with DHCP: its IP shows up in the router's device list. If not, use Circutor's IPSetup.exe with the MAC of the communications board.
  4. Open http://<IP>/ → Network → Address Type: Local address if it reaches the internet through the site router, Embedded modem if it uses a SIM. Save.
  5. Integrations tab → OCPP 1.6. If a licence notice appears, the unit does not have one. According to Circutor's technical service, the latest firmware versions include it: ask their after-sales service for the firmware.
  6. Open http://<IP>:8080/html/setup.html (admin / 1234). Under Charge Box → ID, the serial number. Under Central System → Host URL, your brand's URL (below), starting with ws:// and without the identity at the end. If the page has username and password fields, enter the identity and the panel password.
  7. Press Save (top right) and reboot. http://<IP>/services/cpi/log?app=ocpp1.6 should show CB boot notification: success, and in the panel the charger shows as connected with both sockets.

What to enter to connect it to askacharge.com

OCPP server URLws://askacharge.com/askacharge/ocpp/your-brand — with ws://, unencrypted: the URBAN only supports WS, not WSS. your-brand is your brand identifier on askacharge.com; the unit appends its identity. Before connecting it, tick Access → Allow unencrypted connection on its page in the panel, or the server rejects it.
Charge point identityThe same one you register in the panel when adding the charger. Case-sensitive. With Circutor, the serial number is the easiest choice.
Username and passwordThe URBAN has no username or password fields. askacharge.com requires them from every other charger; for this model we make a named exception, that specific charger tied to the public IP it connects from. Request it by writing to info@askacharge.com with the serial number. If your firmware does have username and password fields, enter the identity and the panel password and no exception is needed.
ProtocolOCPP 1.6J (JSON) or OCPP 2.0.1. Subprotocol ocpp1.6 / ocpp2.0.1.
Before connectingThe charger must be registered in the brand with that identity; otherwise the server rejects the connection. Register under Chargers → Add.

Point your charger at our OCPP test server: free, no account, over wss:// or ws://. You will see what it sends live and we will tell you what would fail when you connect it for real.

Where it usually fails

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.
