RecvMeterValue
With this method, an OCPP server receives Meter Values from an OCPP client. To respond to the receipt of the Meter Values, the method RespMeterValue must be called.
Contrary to the specification, it is possible to receive Meter Value messages without Meter Values in order to increase compatibility with other vendors.
