Speaking OCPP: lessons from building Ignition
Chargers are tiny computers on unreliable networks. Here is how Ignition keeps sessions, payments and telemetry honest.
Electric vehicles are arriving fast in Ethiopia, and every charger needs software that operators can trust. Ignition talks to chargers using OCPP 1.6J and 2.0.1.
Assume the network will drop
Chargers lose connectivity. Ignition treats every message as something that may arrive twice, late or never — and reconciles sessions when a charger reconnects.
Payments tied to energy
Drivers top up wallets with Telebirr or M-Pesa. Sessions reserve funds, meter values settle them, and receipts show exactly how many kWh were delivered.
Operators need the big picture
Live maps of charger health, connector status and revenue let operators spot problems before drivers do.
