Which OCPP URL do I enter on a MENNEKES 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 username (the identity) and password (the one the panel shows when you add the charger) are required: Security Profile 2.

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

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 MENNEKES charger (AMTRON Professional / Professional+) and connect it to another platform

Q: Can a MENNEKES charger be connected to a platform other than the manufacturer's?

Yes. The AMTRON Professional / Professional+, AMEDIO Professional / Professional+, AMTRON Charge Control models speak standard OCPP and let you change the server URL. In the controller's web interface (Bender). With a micro-USB cable in the charger's Config port, open http://192.168.123.123/operator in the browser; over the network, whatever IP the charger has. Username operator and the password from the commissioning sheet shipped with the unit. On an AMEDIO each outlet has its own password. Older AMTRON units (Compact, Xtra, Premium) have no OCPP.

A MENNEKES charger that speaks standard OCPP can be connected to any platform by changing one setting. Here is where that setting lives on AMTRON Professional / Professional+, AMEDIO Professional / Professional+, AMTRON Charge Control, 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 controller's web interface (Bender). With a micro-USB cable in the charger's Config port, open http://192.168.123.123/operator in the browser; over the network, whatever IP the charger has. Username operator and the password from the commissioning sheet shipped with the unit. On an AMEDIO each outlet has its own password. Older AMTRON units (Compact, Xtra, Premium) have no OCPP.

Step by step

Check under State → Firmware version that you have at least 4.00-2139; if not, update from the same interface (Maintenance).
Backend tab: Connection type = Ethernet, Wi-Fi or GSM depending on how it reaches the internet (with GSM, APN and SIM PIN in their section).
OCPP Mode: OCPP-J 1.6.
WebSockets JSON OCPP URL of the Backend: your brand's base URL (below) ending in a slash: wss://askacharge.com/askacharge/ocpp/your-brand/. The controller appends the ChargeBoxIdentity.
OCPP ChargeBoxIdentity: leave it as it is (usually the serial number) and write it down: it is the identity you register in the panel. HTTP Basic Authentication password: the password the panel gave you when you added the charger. Save.
Authorization tab: Enable OCPP Whitelist = On, Enable Local Whitelist = Off, Local Pre-Authorization = Off, so cards and starts are validated by the platform. Save and restart the charger (Maintenance → System → Restart). It connects 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 MENNEKES, 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

Without the trailing slash in the URL the controller does not connect. It is the number one failure with Bender.
The ChargeBoxIdentity accepts no special characters; if you change it, letters, digits and hyphens only.
Every change under Backend needs a restart to apply: if "nothing happens", the restart is missing.
With several outlets (AMEDIO) there is one OCPP connection with two connectors; in the panel it is one charger with two connectors, not two chargers.

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.
