Hardware

If the S0 interface of your meter supports 12V, connect it like this:

S0 circuit

Otherwise you may have to adjust the input voltage.

Software

Set "S0_ENABLE" in the hexabus_config.h to 1.
Adjust all other settings like you would for internal metering.
Compile and flash your image
Go to the "Configuration" page on the web interface
Set the S0 calibration value according to your meter

Your S0 meter can now be used, like the internal metering, via EID 2.
