Do the wallbox need an energy meter installed to work with this?

[PanicMan]

Hello, just tried it out, connected to the wallbox, but the values for current power and charged power are 0 and maximum charge current (I have an PV-Plant and want use this for charging only) is tken over, but the charge current is not changed, still the full 16A... Here my config, Walboxes at v1.3.3: {"ocppConnected":false,"maxChargeCurrent":16,"productId":"76","programVersion":"7.9","firmwareVersion":7,"firmwareRevision":9,"smallFirmwareVersion":2,"smallFirmwareRevision":15,"largeFirmwareVersion":7,"largeFirmwareRevision":9,"lbVersion2":true,"serialNumber":2065258,"meterSerialNumber":"","meterType":0,"factoryChargeLimit":32,"switchChargeLimit":16,"rfidReaderPresent":false,"rfidMode":"RFID_DISABLED","powerbackupStatus":2,"lastTemperature":20,"warningTemperature":65,"cutoffTemperature":70,"reducedIntervalsEnabled":false,"reducedCurrentIntervals":[{"schemaId":1,"start":"00:00:00","stop":"23:59:59","weekday":8,"chargeLimit":6}],"softwareVersion":185,"availableVersion":0,"updateUrl":"","networkMode":1,"networkType":0,"networkSSID":"Panic's WLAN 2.4","webNetworkPassword":"","networkAPChannel":6,"ethNetworkMode":0,"gcConfigTimestamp":null,"gcloudActivated":false,"gcActivatedFrom":null,"ethGateway":"","ethDNS":"","ethIP":"","ethMask":24,"localLoadBalanced":false,"groupLoadBalanced":true,"groupLoadBalanced101":false,"energyReportEnabled":false,"master":true,"timezone":null,"slaveList":[{"reference":"Slave","serialNumber":2046640,"lastContact":1639758576074,"online":false,"loadBalanced":false,"phase":16,"productId":76,"meterStatus":1,"meterSerial":"","chargeStatus":0,"pilotLevel":16,"accEnergy":-1,"firmwareVersion":7,"firmwareRevision":9,"wifiCardStatus":1,"connector":"INITIALIZATION","accSessionEnergy":0,"sessionStartValue":-1,"accSessionMillis":0,"sessionStartTime":null,"currentChargingCurrent":-1,"currentChargingPower":0,"nrOfPhases":1,"twinSerial":-1,"cableLockMode":0,"minCurrentLimit":6,"dipSwitchSettings":8076},{"reference":"Master","serialNumber":2065258,"lastContact":1639758603933,"online":false,"loadBalanced":false,"phase":1,"productId":121,"meterStatus":1,"meterSerial":"","chargeStatus":0,"pilotLevel":16,"accEnergy":-1,"firmwareVersion":7,"firmwareRevision":9,"wifiCardStatus":2,"connector":"NOT_CONNECTED","accSessionEnergy":0,"sessionStartValue":-1,"accSessionMillis":0,"sessionStartTime":null,"currentChargingCurrent":-1,"currentChargingPower":0,"nrOfPhases":1,"twinSerial":-1,"cableLockMode":0,"minCurrentLimit":6,"dipSwitchSettings":8092}],"gridNetType":"UNKNOWN","slaveControlAvailable":true,"currentMultiplier":100,"rfPower":31,"twinSerial":-1,"twinSwitchLimit":0,"energySerials":[],"packageVersion":"1.3.3","cableAutoUnlocked":false,"internetSharingEnabled":false,"webAPPassword":null,"standalone":false,"castra":false}
