not sure if this problem is a real issue:
my power factor measurement is of by around 0.13 (showing 0.87 with only water heater running)
according to documentation of emonlib this can by adjusted by with the parameter "phase_shift" in esp32emon.h line 107
https://docs.openenergymonitor.org/electricity-monitoring/ctac/emonlib-calibration-theory.html
// Phase 1 sensors
emon1.voltage(V1, CV1, 1.732); // Voltage: input pin, calibration, phase_shift
emon1.current(I1, CI1); // Current: input pin, calibration.
i tried all kind off different values ( 0, 0.5, 0.6, 1.0, 1.28, 1.7....) but the power factor does not seem to change.
But maybe the Problem is not in the code?
im using 3X 60A/1V SCT0013 Clamps
connected to ESP32dev board
Voltage Bias according to wiring diagram and code setup for 3 phases (only 1 Voltage measurement)
