3 Phase meter

I'm preparing a Domoticz setup for someone else.
It turns out they have a 3 phase meter Landis & Gyr E350.
I have a 1 phase meter so I can't test the 3 phase environment at my place.
Domoticsz runs on a PI-3B+ and using the P1 over USB and an inverter and an FTDI into the USB0 port.
This setup runs fine at my place.

However I wonder what will happen when I bring the meter into the 3 phase environment.
Will automatically the L1, L2 and L3 meters show up in the Devices window of Domoticz?

Who can tell me if I have to do extra things in the configuration for using this 3 phase meter setup?

And an additional question, Is the Landis&Gyr E350 also having an inverted P1 output?

Yes, the missing devices will be created automagically.
if not, just delete and recreate the hardware

yes, inverted. you may need a 1k pullup between pin 2 and 5 at the meter, try without first.
