    Aeon ZW095 Gen 5

    I just installed a Aeon Labs Gen5 ZW095 Home Energy Meter (HEM).

    There are 2 clamps as expected these go on the 2 phases of power coming into the home.
    Then there is just 1 wall plug which is connected to one of the 2 phases. This powers the unit and I assume measures the voltage.

    But there is a child device for the other phase voltage.
    How would that work?
    What are the physics behind it?
    Are they just assuming the same voltage on both phases?
    Without a physical wire connected to the other phase they can't possibly know the voltage.

    My Sense HEM on the other hand wires into both phases which then obviously can measure the 2 voltages accurately.

    I'm thinking if I have a big motor on 1 phase (or even just turn on a hair dryer) then that phase voltage will droop and the readings will be off. There is no spec for the "accuracy" that I see in the doc - just a range of 0A-200A so that doesn't inspire confidence.

    I just installed one myself (replaced a Sense monitor).

    It does appear they are assuming Voltage is same for Line 1 and Line 2. In reviewing the values that are provided, they are identical...
