Ocpp, possible to send heartbeat signal?

[Jonas S]

Hello

Would it be possible, maybe through websocket? to send heartbeat command to ocpp backend? 
What I'm really after is to use a energy meter and send consumption to the backends Load managment but if I could mange to figure out just the heartbeat function I should be able to get the rest working by my self


json script for heartbeat response:
{
    "$schema": "http://json-schema.org/draft-04/schema#",
    "id": "urn:OCPP:1.6:2019:12:HeartbeatResponse",
    "title": "HeartbeatResponse",
    "type": "object",
    "properties": {
        "currentTime": {
            "type": "string",
            "format": "date-time"
        }
    },
    "additionalProperties": false,
    "required": [
        "currentTime"
    ]
}
