Support for EM340 carlo gavazzi

[marcinczenko]

Is EM340 carlo gavazzi energy meter supported (MODBUS RTU RS485)?

It's not directly supported (you can not directly select it from the menu), but i see that it can work at 9600 bps and no parity.
So it should be possible to make it work by choosing the Custom meter, and defining the registers manually.

@marcinczenko have you been able to make this work? If you have, could you post the custom settings?
