The ATM90E32 chip has a high-precision built-in ability to count the amount of consumed energy on a per-phase basis.
For each phase both the Forward and Reverse active energy is counted in watt-hours.
Forward Active Energy is used to count consumed energy, whereas Reverse Active Energy is used to count exported energy
(e.g. with solar pv installations).

The counters are reset every time a given active energy value is read from the ATM90E32 chip.
Current implementation targets users who retrieve the energy values with a regular interval and store them in

If the power, power_factor, reactive_power, forward_active_energy, or reverse_active_energy configuration variables
are used, care must be taken to ensure that the line ATM90E32's voltage is from is the same phase as the current
transformer is installed on. This is significant in split-phase or multi phase installations. On a house with 240
split-phase wiring (very common in the US), one simple test is to reverse the orentation of the current transformer
split-phase wiring (very common in the US), one simple test is to reverse the orientation of the current transformer
on a line. If the power factor doesn't change sign, it is likely that the voltage fed to the ATM90E32 is from the other
phase.

allow a seperate VA2 to be input on the J3 pads. Make sure that current taps connected to CT 1-3 are on the phase
The CircuitSetup Expandable 6 channel board can easily handle this situation by cutting the jumpers JP12/13 to
allow a separate VA2 to be input on the J3 pads. Make sure that current taps connected to CT 1-3 are on the phase
from which VA is fed (the barrel jack) and the taps connected to CT3-6 are on the phase from which VA2 is fed. See
the CicuitSetup repo for more details on this.
If a mulit board stack is being used, remember to cut JP12/13 on all boards and to feed VA2 to each board. VA is
If a multi board stack is being used, remember to cut JP12/13 on all boards and to feed VA2 to each board. VA is
fed to all boards through the stacking headers. Another detail is that each voltage transformer needs to have the
same polarity; getting this backwards will be just like having it on the wrong phase.

Note that the current measurement is the RMS value so is always positive. They only way to determine direction is to
look at the power factor. If there are only largely resistive loads and no power sources, (PF almost 1), it is simpler
to just create a template sensor that computes power from Irms*Vrms and ignore all these details. On the other
hand, one might be surprised how reactive some loads are and the CirciuitSetup designs are able to
handle these situations well.

Harmonic power in AC systems refers to deviations from the ideal sinusoidal waveform, caused by multiples of the
fundamental frequency. It results from non-linear loads and can lead to issues like voltage distortion, equipment
overheating, and misoperation of protective devices. The ATM90E32 can output advanced harmonic power measurements

Peak current in AC systems refers to the maximum value of the alternating current waveform. It signifies the highest
magnitude reached during each cycle of the sinusoidal waveform. Peak current is relevant for sizing components and
assessing the capacity of electrical equipment in the system. This advanced measurement is avaiable from the ATM90E32.
Peak current can be displayed in signed or unsigned format using a bolean parameter which spans all phases.
