Can a Circontrol charger be connected to a platform other than the manufacturer's?

Yes. The eNext Elite, eNext Park, Raption, Wallbox eHome (with communications module) models speak standard OCPP and let you change the server URL. In the charger's web interface (by its IP on the local network), Integrations tab → OCPP 1.6 → Link.

Which OCPP URL do I enter on a Circontrol for askacharge.com?

wss://askacharge.com/askacharge/ocpp/your-brand, where your-brand is the brand identifier on askacharge.com; the charger appends its identity. The identity must match the one registered in the panel and the password stays blank unless the charger's OCPP credential has been enabled.

Do I lose the manufacturer's app when I set OCPP on a Circontrol?

Some app functions move to the OCPP platform (start, cards, statistics). The hardware stays the same and you can go back by changing the URL again.

How to change the OCPP server URL on a Circontrol charger (eNext Elite) and connect it to another platform

A Circontrol charger that speaks standard OCPP can be connected to any platform by changing one setting. Here is where that setting lives on eNext Elite, eNext Park, Raption, Wallbox eHome (with communications module), exactly what to enter, and where people usually get stuck. Written by a platform (askacharge.com), but the procedure works for any.

Where the setting lives

In the charger's web interface (by its IP on the local network), Integrations tab → OCPP 1.6 → Link.

Step by step

Open the charger's IP in a browser (it is in the manual or assigned by your router). Log in with the web interface credentials.
Go to Integrations, enable the OCPP 1.6 integration and click Link to open the OCPP setup.
Charge Box tab: in OCPP Identifier enter the identifier you register on askacharge.com (unique within your brand).
Central System tab: in Host URL your brand's base URL (below). Leave Use OCPP time synchronization on Yes.
Recommended: Energy for Start/Stop transaction and Energy for MeterValues set to PARTIAL, and User confirmation required on remote start set to NO, so remote starts and QR payment work without touching the charger.
Save and reboot. Check at http://<IP>/services/cpi/log?app=ocpp1.6 that CB boot notification: success appears.

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 Circontrol, the serial number is the easiest choice.
Password	Blank by default. If you enable the charger's OCPP credential in the panel (recommended for units exposed to the internet), the username is the identity and the password is the one the panel generates: OCPP Security Profile 2.
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

The identifier must be unique: with several eNext units, do not leave the default value on all of them.
If User confirmation required on remote start stays on Yes, the driver will have to press the charger after paying by QR and it will look as if the payment did not start the charge.
The log at /services/cpi/log is the fastest way to see why it will not connect (certificate, DNS, identity rejected).

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.
