Duplicated parameters in MeterValues

Teltonika Energy

Hello,
I’ve connected a charger to a CS via OCPP 1.6J and the charger sends a parameter duplicated in MeterValues message.

The charger’s product code: EVC1201P1000

The message:
Incomming REQ: [2,“146”,“MeterValues”,{“connectorId”:1,“transactionId”:3,“meterValue”:[{“timestamp”:“2023-11-04T00:01:07Z”,“sampledValue”:[{“value”:“576340”,“context”:“Sample.Periodic”,“measurand”:“Energy.Active.Import.Register”,“location”:“Outlet”,“unit”:“Wh”},{“value”:“5.9”,“context”:“Sample.Periodic”,“measurand”:“Current.Import”,“phase”:“L1”,“location”:“Outlet”,“unit”:“A”},{“value”:“6.0”,“context”:“Sample.Periodic”,“measurand”:“Current.Import”,“phase”:“L2”,“location”:“Outlet”,“unit”:“A”},{“value”:“6.0”,“context”:“Sample.Periodic”,“measurand”:“Current.Import”,“phase”:“L3”,“location”:“Outlet”,“unit”:“A”},{“value”:“6”,“context”:“Sample.Periodic”,“measurand”:“Current.Offered”,“unit”:“A”},{“value”:“34.8”,“context”:“Sample.Periodic”,“measurand”:“Temperature”,“location”:“Body”,“unit”:“Celsius”},{“value”:“4202”,“context”:“Sample.Periodic”,“measurand”:“Power.Active.Import”,“location”:“Outlet”,“unit”:“W”},{“value”:“4202”,“context”:“Sample.Periodic”,“measurand”:“Power.Active.Import”,“location”:“Outlet”,“unit”:“W”}]}]}]
Formatted message sampledValue array:
{
“value”:“576340”,
“context”:“Sample.Periodic”,
“measurand”:“Energy.Active.Import.Register”,
“location”:“Outlet”,
“unit”:“Wh”
},
{
“value”:“5.9”,
“context”:“Sample.Periodic”,
“measurand”:“Current.Import”,
“phase”:“L1”,
“location”:“Outlet”,
“unit”:“A”
},
{
“value”:“6.0”,
“context”:“Sample.Periodic”,
“measurand”:“Current.Import”,
“phase”:“L2”,
“location”:“Outlet”,
“unit”:“A”
},
{
“value”:“6.0”,
“context”:“Sample.Periodic”,
“measurand”:“Current.Import”,
“phase”:“L3”,
“location”:“Outlet”,
“unit”:“A”
},
{
“value”:“6”,
“context”:“Sample.Periodic”,
“measurand”:“Current.Offered”,
“unit”:“A”
},
{
“value”:“34.8”,
“context”:“Sample.Periodic”,
“measurand”:“Temperature”,
“location”:“Body”,
“unit”:“Celsius”
},
{
“value”:“4202”,
“context”:“Sample.Periodic”,
“measurand”:“Power.Active.Import”,
“location”:“Outlet”,
“unit”:“W”
},
{
“value”:“4202”,
“context”:“Sample.Periodic”,
“measurand”:“Power.Active.Import”,
“location”:“Outlet”,
“unit”:“W”
}

Please see the two last parameters. Is the duplication expected? Is it documented somewhere? Why it happens? How to avoid it?

The issue happens when the charger is configured that way (either accidentaly or by a reason). Like:
change-configuration
{
“key”:“MeterValuesSampledData”,
“value”:“Power.Active.Import,Power.Active.Import”
}
