Hosted OCPP proxy — proxy.joulo.nl
The same open-source OCPP proxy/splitter as on GitHub, operated by Joulo. No servers or Docker: point your charger at our WebSocket endpoint and mirror traffic to your primary back office and to Joulo (or another secondary CSMS).
// Who is this for?
Charger with only one OCPP backend
Many chargers only allow one CSMS URL. You connect first to proxy.joulo.nl; the proxy forwards traffic to your existing platform (primary) and sends a read-only copy to extra backends—for example Joulo for ERE registration.
- Primary: your current charge management or vendor cloud. Secondary: Joulo or analytics—as described on the OCPP proxy page.
- Only the primary CSMS can send commands to the charger; secondary backends receive a mirror for monitoring.
// Configuration
WebSocket URL on your charger
In your charger's OCPP or back-office menu, set the backend URL to the hosted endpoint, with your charge point ID in the path (same ID you use with your primary CSMS):
Replace CHARGER-001 with your charger's ID. The proxy appends this ID to upstream URLs you configure with Joulo or in self-hosting—see the full guide.
