Generic Integration guide
A generic guide for connecting any OCPP-compatible charge point to Monta. Covers requirements, OCPP server configuration, certificate setup, and troubleshooting.
Before you begin
Search the Monta integration guides for a guide specific to your charge point model. If none exists, verify that your model is on the Monta supported charge points list. This guide applies only to supported models. Unsupported models have not been tested and Monta cannot guarantee a successful integration.
Requirements
- A charge point supporting OCPP 1.6-J minimum (OCPP 2.0.1 also supported)
- Network connectivity for the charge point (wired, Wi-Fi, or GSM/SIM)
- Configuration access via web interface or manufacturer software
1. Access the charge point configuration interface
Log in to the charge point's configuration interface. Refer to the manufacturer's installation manual if unsure.
2. Set up network connectivity
Navigate to the network or OCPP settings section and configure a working network connection.
- If using a Monta SIM card: APN =
INTERNET, leave username and password blank. Contact WirelessLogicNordic if activation is uncertain. - For all other connectivity types, refer to the charge point manufacturer's instructions.
3. Configure the OCPP server URL
- OCPP server URL:
ocpp.monta.app - Protocol: WebSocket Secure (WSS)
4. Set the port number
Port: 443 (standard port for secure WebSocket connections).
5. Configure the WebSocket path
Set the path to blank. If the charge point does not automatically append a forward slash, set it to /.
6. Troubleshooting URL, port, and path
If separate fields are not available, use one of these combined formats:
ocpp.monta.appwss://ocpp.monta.appwss://ocpp.monta.app/wss://ocpp.monta.app/SerialNumberwss://ocpp.monta.app:443wss://ocpp.monta.app:443/wss://ocpp.monta.app:443/SerialNumber
Replace SerialNumber with the actual serial number. If in doubt about the correct format, contact the manufacturer.
7. Add a certificate (model-dependent)
- If you can select but not upload: look for a certificate named Amazon Root CA 1.
- If you can upload but not select: upload this certificate.
8. Identify the serial number / ChargeBox ID
The terminology varies by manufacturer. The most common label is ChargeBox ID. This field defaults to the charge point serial number. Note the value — you will enter it when adding the charge point to Monta.
9. Save and apply settings
Save and apply the configuration. Restart the charge point or network services if required.
10. Verify the connection
Add the charge point to Monta. If it shows as "offline", refer to the troubleshooting section below.
Example configuration
-
OCPP Server URL:
wss://ocpp.monta.app -
Port:
443 -
WebSocket path:
/
Troubleshooting
-
URL, port, path: check for typos in
ocpp.monta.app, port443, path, and protocol (WSS). - Network: confirm the charge point has internet access and no firewall is blocking the Monta server.
- Logs: review the charge point's diagnostics logs for error messages.
- Firmware: update to the latest firmware, as updates may fix connectivity issues.
- ChargeBox ID: confirm it matches exactly what you entered in Monta.
-
WSS not supported: use
ws://ocpp.monta.appwith port80instead.
Support
Consult the charge point's user manual or contact the manufacturer's support team. Contact Monta support if the issue persists.
