How to change the OCPP server URL on a go-e charger

A go-e charger that speaks standard OCPP can be connected to any platform by changing one setting. Here is where that setting lives on Charger Gemini, Gemini flex, Gemini 2.0, Pro, HOMEfix/HOME+ (V3), 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 go-e Charger app: Internet → OCPP tab (in older app versions, Settings → Connection → OCPP).

Step by step

  1. Update the firmware from the app. V3 units (HOMEfix/HOME+) only have OCPP on recent firmware.
  2. Connect the charger to your Wi-Fi (Internet → Wi-Fi). To get in the first time, the charger's hotspot and key are on the reset card in the box.
  3. Internet → OCPP: enable OCPP 1.6; in Server URL enter the URL complete with the identity: wss://askacharge.com/askacharge/ocpp/your-brand/goe123456, where 123456 is the serial number (the six digits in the hotspot name). If you prefer the base URL, enable Append serial number to URL.
  4. Internet → Reboot. Register in the panel exactly the identifier you put at the end of the URL.

What to enter to connect it to askacharge.com

OCPP server URLwss://askacharge.com/askacharge/ocpp/your-brand/identity — the full URL, with the charger identity at the end: on go-e there is no separate field for it. your-brand is your brand's identifier on askacharge.com (shown under Chargers → Add, with the full URL ready to copy).
Charge point identityThe same one you register in the panel when adding the charger. Case-sensitive. With go-e, the serial number is the easiest choice.
PasswordBlank 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.
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.

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.
