Made it this way.
For Voltage, is just to choose Volt sensor in Domoticz Hardware tab for Virtual sensors. Be aware to chose the correct IDx, as always!
In the same way I made 2 Custom sensors, to be used for Amperé & Power.
When Voltmeter is done and working, you can see the values in Domoticz Log
Read Ampere and Power, I used a
dZvent script as follows. I made the script [with some help

] in Domoticz Setup tab. Save and activate, when ready!
................................................................................................................
return {
on = {
timer = {
'every 2 minutes'
}
},
execute = function(dz, dev)
dev = dz.devices("Spänning drift")
temp = dz.utils.stringSplit(dev.sValue,";")
dz.devices('Strömförbrukning drift').updateCustomSensor(temp[2])
dz.devices('Effektförbrukning drift').updateCustomSensor(temp[3])
end
}

"
Spänning drift" = Name of the virtual Volt sensor. You choose the name, but it MUST be the same as in Domoticz!
"
Strömförbrukning drift" = Name of the custom sensor for Amperé [can be any name, but it MUST be the same as in Domoticz]
"
Effektförbrukning drift" = Name of the custom sensor for Power [can be any name, but it MUST be the same as in Domoticz]
