Domoticz

Why? Because I dont wanna keep an RPI2 in our electricity room 'meterkast' with a USB cable to our P1 meter.
I prefer to have a device like this working over LAN instead, so i can also pick it up from more then 1 domotica system

That topic you send me to is very nice, but thats not what Im looking for (already ordered the enelogic p1) Im specifically asking if it would be possible to implement support for local reading from this enelogic p1 device in Domoticz Just like the P1 meter LAN is supported.

That's what i meant with using the $11 Serial to Ethernet module.... no need for a €79 costing module from Enelogic.
The Serial Ethernet way is already supported in Domoticz by choosing the "P1 Meter LAN" hardware in Domoticz. Haven't tried though, but i don't see why it wouldn't work.

Only requires a bit of soldering, but that isn't hard.

I solved it this way http://www.meerwijk.frl/domoticz-en-p1-enelogic/

Works as a breeze!
