Build your own EV Smart charge solution
summary
A working CPO is implemented and deployed across 2500 charge points, proving home/enterprise control at scale; it uses Java, Quarkus and Vaadin with a WebSocket JSON stack implementing OCPP 1.6 JSON over WebSocket. The system accepts boot/status/meter messages, issues RemoteStart/Stop and stacked charging profiles, ties into Home Assistant for solar-aware dynamic amp limits, and the demo shows live meter updates and automatic amp adjustments based on production, so the solution actually controls charging and stops/starts transactions as expected.
