Which OCPP URL do I enter on a GARO 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 GARO?

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 GARO charger (GLB+) and connect it to another platform

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

Yes. The GLB+, GTB+, Twin+, LS4, Entity Pro models speak standard OCPP and let you change the server URL. It depends on the family. GLB+, GTB+, Twin+ and LS4: in the controller's web interface, with a laptop plugged by micro-USB cable into the controller's config port and the browser on 192.168.123.123 (user operator, password cherry_zone or yellow_zone), Backend menu. Entity Pro: in the GARO Connect app as installer, Third-party CPO/OCPP settings. GARO asks for a certified electrician to do it.

A GARO charger that speaks standard OCPP can be connected to any platform by changing one setting. Here is where that setting lives on GLB+, GTB+, Twin+, LS4, Entity Pro, 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

It depends on the family. GLB+, GTB+, Twin+ and LS4: in the controller's web interface, with a laptop plugged by micro-USB cable into the controller's config port and the browser on 192.168.123.123 (user operator, password cherry_zone or yellow_zone), Backend menu. Entity Pro: in the GARO Connect app as installer, Third-party CPO/OCPP settings. GARO asks for a certified electrician to do it.

Step by step

Add the charger on askacharge.com with the identity you will use (the serial number, no spaces or special characters) and keep the panel's password.
GLB+, GTB+, Twin+, LS4: with the charger de-energised, open the cover and connect the laptop to the controller's micro-USB port with a cable that carries data (not a charge-only one). Twin+ and LS4 have two controllers: the right-hand one is the master.
Open 192.168.123.123 (new interface, white background). On older firmware: 192.168.123.123/operator/operator, or on Twin+/LS4 ports :81 and :82 for each outlet. Log in as operator.
Backend → Connection menu: Connection Type = Ethernet or GSM depending on how it reaches the internet. In OCPP ChargeBoxIdentity (ChargePointID), the identity registered in the panel. OCPP Mode = OCPP-J 1.6.
WebSockets JSON OCPP URL of the Backend: wss://askacharge.com/askacharge/ocpp/your-brand/, ending in a slash; the controller appends the ChargeBoxIdentity. In the same menu's Basic Auth password field (on these controllers, HTTP Basic Authentication password), the panel's password.
Save, then Restart. When the LED is green again, log back in and under Diagnostics check Connection State (Backend) reads Connected.
Entity Pro: in GARO Connect, as installer, pick the location and the master charger → Third-party CPO/OCPP settings. In GaroDeviceId, the identity registered in the panel; in GaroRemoteCsmsUrl, wss://askacharge.com/askacharge/ocpp/your-brand (if the field is a drop-down, choose manual entry). Save, restart and repeat on each master in the installation.

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 GARO, 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://`). If your model only supports unencrypted `ws://`, it can be allowed charger by charger on its page in the panel, and the password is still required.
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.

Want to check it before signing up for anything?

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

Without the trailing slash in the URL, the GLB+/LS4 controllers do not connect. Other brands use the same controller and it is the number-one failure.
A "charge-only" micro-USB cable does not open the interface: it looks as if the controller is not responding.
Every change under Backend needs a Restart. If it "does nothing", the restart is missing.
Published guides for the GARO Connect app show no password field for the Entity Pro. askacharge.com requires one: if your app does not have it, write to us before going further and we will sort it out with you.
On Twin+ and LS4, with the legacy interface changes are made on the master controller only.

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.
