Ocpp-809 | Driver

In the context of OCPP, a "driver" usually refers to the software library or agent installed on the Charging Station Controller. It acts as a bridge between the charger's hardware (contactors, meters, RFID readers) and the OCPP protocol stack.

If you are looking for an OCPP implementation to drive hardware, resources like EVCC (Electric Vehicle Communication Controller) or OpenEVSE are the standard software "drivers" used to bridge hardware with the OCPP cloud.

Please clarify if you meant the LED hardware (OCP-809) or the EV protocol (OCPP), and I can provide more targeted technical specifications.

Title: The Charge Point Diaries: A Post-Mortem on OCPP-809

Subject: Development of a custom OCPP (Open Charge Point Protocol) driver for legacy hardware integration.

You bought 50 DC fast chargers in 2019 that speak only Modbus RTU. The manufacturer went out of business. To connect them to a modern CPO (Charge Point Operator) backend, you install an industrial gateway running the OCPP-809 driver.

Two days before launch, we ran a load test. The driver crashed after 400 transactions.

The legacy chargers were sending MeterValues every second. OCPP 1.5 allowed this. OCPP 2.0.1 expects a structured TransactionEvent with specific data types.

The Series 4 units were sending power as a string. "value": "14.4kW". The OCPP 2.0.1 schema demanded a float. "value": 14.4.

The driver’s strict unmarshalling was panicking. I spent a night writing a "Sanitizer" middleware.

// Pseudo-logic for the Sanitizer
func CleanLegacyPower(input string) float64 
    // Strip non-numeric characters
    s := strings.ReplaceAll(input, "kW", "")
    val, err := strconv.ParseFloat(s, 64)
    if err != nil 
        return 0.0 // Fail safely, log error
return val

Therefore, an ocpp-809 driver is the middleware that takes the raw voltage, current, and state data from an older 809-based controller and converts it to JSON payloads over WebSockets (OCPP).
