Hello,
I’m hoping someone has some insight on this item, I’ve been working over the last couple weeks (in my downtime) to calibrate and integrate the CircuitSetup Energy Meter de5b30 into my energy monitoring, but have been running into consistent issues where the watts stat is significantly lower than my Solar system and utility report for me.
Before running to my utility screaming they’re overcharging me i figured i would do some basic arithmetic and found that the watt statistic doesn’t align.
Just plugging my amp measurement into an online calculator (i don’t trust myself with basic multiplication) shows I’m measuring almost ~230w low on each clamp. This difference in reporting aligns with what my solar system reports which is about ~500w more than what the CTs report.
Any guidance or assistance is greatly appreciated.

## Semi-Automatic Calibration ##
# See https://esphome.io/components/sensor/atm90e32.html#calibration
# WHEN CALIBRATION IS ENABLED, calculated values for offset and gain stored in memory take priority over config values
# To save calculated calibration values, copy them from the logs to your config
# then use the clear buttons to clear the calibration values from memory
# Values are stored in the variables for gain below and offsets in their corresponding files
# under /calibration/6chan_xxxx_offset_calibrations.yaml
offset_calibration: "true"
gain_calibration: "true"
## Gain Calibration Values ##
# Change current_cal_ctX value to the corresponding CT's that you're using
