Recognise this?
A CPMS down for six hours costs €10k+ in revenue - but you can't migrate a corridor station without zero-downtime tooling.
Your hardware vendor wants diagnostic access for warranty claims. You can't share full CPMS credentials — that's a security risk.
Your platform shuts down or no longer fits. Migrating is risky: one wrong switch and you lose sessions, transactions or customer trust.
Concretely, in four points
Hot-standby and parallel routing: your chargers can talk to multiple CPMS systems simultaneously without data loss.
Scoped OCPP event streams to OEMs or partners — without sharing your CPMS credentials.
Audit-grade event logging as single source of truth for billing disputes or warranty claims.
Zero-downtime migration — proven for Etrel shutdown (Feb 2025) and Everon shutdown (Dec 2025).
Migration, an approach, not a separate product
Migrating away from a disappearing platform isn't a button you press, it's an approach in which Gateway is the technological enabler. With Gateway we run parallel temporarily: your existing CPMS keeps running while ihomer Charge Management is built up next to it. Sessions route to both systems. When you trust the new environment, you cut the old one. No big-bang cutover, no lost sessions, no operational interruption.
For customers of disappearing platforms
Etrel shut down Feb 2025. Everon follows Dec 2025. We have the approach to do those migrations without data loss.
For customers with an existing CPMS who want different
Run parallel until you trust it, then switch.
For customers who once built their own
In-house CPMS builds were once good decisions, but maintenance load grows. We take it over without you losing your investment.
The question we hear every week
Can Gateway run alongside our in-house CPMS?
Yes, that's exactly what Gateway is built for. For in-house CPMS teams, Gateway is the access layer you don't build yourself: hot-standby, OEM proxy, and audit logging. You keep your investment, you keep control over your data, and you get the layer that belongs between chargers and platform.
