OCPI 2.2.1 roaming
Your chargers, in every app.Your drivers, on every network.
We connect your CSMS to roaming partners and hubs over OCPI 2.2.1, as CPO, eMSP or both. Locations, sessions, CDRs, tariffs, tokens and commands.
- Free & open
- OCPI is a free, open protocol, maintained by the EVRoaming Foundation.

Direct, through a hub, or both
Peer to peer
A direct OCPI link with each partner. Full control over every agreement and tariff.
We build and run both, and you can mix them on one network.

Roaming only pays when the link never drops a session. Everything a live OCPI connection needs is built in and monitored.
