    Since you have not yet received an answer I may be able to help (by guessing):

    “(as now it only considers 120v when calculating amps)”

    This does not make sense as it is expressed. It may mean ” it only considers 120v when calculating a WATTS”.

    For those who don’t get it:  The sense coils (clamps) measure only amperes. The voltage output of the coil is directly proportional to the ampere load on the circuit. The voltage applied to the load is not needed. However, the most useful unit of measurement is watts. Watts must be calculated using the amps measured by the coil, along with the voltage applied to the load and the Power Factor. For home use, the Power Factor is assumed to be 1  because home electric meters do not consider it.

    Emporia Support: Since there are hundreds of thousands of apartment/condo units supplied by this unsupported configuration, it probably is a good ideas to tell people in advance with your documentation.

    Since the coils measure amperes, is it a correct assumption that the ampere reading for each coil is correct?

    Can the multiplier for the mains be changed so that the correct wattage shows?

    Is the wattage reading for each single coil based on 120 Volts with the multiplier set at 1? (The voltage value at each coil on the mains should be measuring the nominal single phase voltage.)

    The Condo unit electric service is  two leg 120/208 wye. Emporia Support already said it is not supported.

    General comment: Some wireless devices do not connect if there are spaces or special characters (other than hyphen) in the SID. Best practice is not to use special characters.
