You are not sending readings.

```
{
   "electricity":{
      "received":{
         "tariff1":{
            "reading": 1 // <-- you miss this
            "unit":"kWh"
         }
     }
}

```

I think you are not getting the good values from the p1 meter or they cannot be parsed by the node-dsmr parser.
