Energy monitor/ 3-Phase Power / Modbus Profile EMU Professional 3/5 TCP/IP

You need to set datatype, not bus_datatype. bus_datatype is needed only when it's different from the main datatype.
Try this for active energy register:

Code:

{ "name": "active energy", "datatype": "int64", "type": "register", "address": 4201 }

Thanks to both of you, I didn't expect such a quick answer

I've tried a lot. Modbus is active on the energy meter.

With the following I only get "Illigal function" and can not add it to any object anymore:

{
  "manufacturer": "Hugo",
  "description": "EMU_Professional_TCP_IP-LM5_Profile_V3.08",
  "mapping": [
    { "name": "active energy", "datatype": "int64", "type": "register", "address": 4201 }
  ]
}
