Roaming is what lets a driver who belongs to another network charge at your station and be billed correctly for it. OCPI is the open interface that carries the locations, the tariffs, the live status and the records between the two sides. Idle capacity becomes revenue without you signing up every driver yourself.
A partner is connected in minutes, not in a project
Connection runs over the OCPI 2.2.1 three-step handshake, verified end to end with a real partner. You publish your locations and tariffs; within the agreement a partner can also send a remote start to one of your connectors.

Records
CDR is the record the money is argued over
Every roaming session produces a charge detail record — who charged, where, how long, how much energy, at which tariff. Sessions and CDRs are held together, so a dispute is answered from the record rather than from a spreadsheet exported afterwards.

Settlement
What each side owes, calculated rather than reconciled
Cross-network charging leaves both sides owing each other. Settlement runs against the same records the invoices are drawn from, so the closing figure is produced by the system instead of being agreed by hand at month end.

Roaming is per agreement: which partner sees which locations, at which tariff, with which rights. Your brand stays in front of the driver.
Yes, and that is exactly what OCPP is for. If the chargers speak OCPP, changing platform is in essence repointing an endpoint: the devices stay, the software behind them is swapped. The same route works from the platforms known in the market — AMPECO, Virta, Monta, be.ENERGISED, has·to·be, ChargePoint, EVBox, GreenFlux — and in the other direction too; an open protocol is open precisely so that you are locked in to neither a hardware nor a software vendor. Tariffs, users and opening balances are imported by us, and the old system's history can be kept as an archive.
What is OCPI and how does it differ from OCPP?
OCPP connects a charger to its management software. OCPI connects two networks to each other. One is about running your own hardware, the other about letting another operator's drivers use it — you need both to roam.
What is a CDR?
A charge detail record: the settled account of one session — location, connector, start and end, energy, duration and the tariff applied. It is what roaming partners bill each other from, so it has to be produced by the system rather than assembled later.
Do I have to open every station to roaming?
No. Locations are published per agreement, so you can open a site, a region or a tariff group and keep the rest closed.
What is OCPI and why does roaming need it?
OCPI is the open standard charging networks use to pass locations, tariffs, sessions and CDRs to each other. Roaming is built on it, so there is no separate integration project for every partner.
How long does connecting a partner take?
Minutes, through the OCPI 2.2.1 three-step handshake. The connection has been verified end to end with a real partner; after that, which location appears at which tariff follows the agreement.
What exactly is a CDR?
A CDR (Charge Detail Record) carries who charged, where, for how long and how much energy for a single session. It is the record the money is argued over, and settlement is calculated from it.
Whose brand does the driver see in roaming?
Yours, on site and on the map. Roaming only lets drivers from other networks use your stations; the customer relationship and the brand stay with you.
