OCPP Central System and Charge Point emulator.

A modern, extendable OCPP 2.0.1. charging station management system

An OCPP 1.6 and 2.1 compliant Charging Station Management System for managing EV charging infrastructure. Handles real-time WebSocket communication with charging stations, OCPI 2.2.1/2.3.0 roaming, ISO 15118 Plug and Charge, a REST API for operators, and two React frontends for operators and drivers.

OCPP Server with GUI, CLI, Groovy

A secure, lightweight OCPP proxy server designed as a Home Assistant add-on that enables intelligent EV charger sharing. Supports both OCPP 1.6 and OCPP 2.0.1 protocols with automatic version detection.

Boilerplate code for an OCPP central system to quickly get it running.

OCPP Central System as Service

Type-safe OCPP WebSocket RPC client & server with pub/sub, session management, and clustering support

OCPP gateway service for the Eveys EV-charging platform. Owns every charger's WebSocket connection; exposes gRPC + Kafka events + a REST API for the rest of the platform.

Electroop: OCPP 1.6J/2.0.1/2.1 and OCPI 2.2.1 EV charging platform (CPMS/CSMS, white-label eMSP, card payment at the charger, OCPI proxy) with Türkiye EPDK/GİB reporting. Public API + MCP examples, no product code.

Self-hosted OCPP 1.6J / 2.0.1 CSMS for small businesses - wallbox and charge point management, RFID chips, charging limits, reports. One Rust binary, one SQLite file.

SolarNode OCPP support

A tool that pretends to be one or many EV charging stations talking to your back-office (CSMS). You spin up devices in a web UI, start sessions, send meter readings, run reservations, push firmware updates — everything a real station does — without owning a single hardware unit.
