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.
