I’m exited to share my achievements concerning the capture and presentation of the electricity characteristics at home based on the information provided by my electricity meter via the P1 port on it.
This is the list of parameters I get from my electricity meter:
This is the device circuitry:
and the ESP-12 outside the electric cabinet to not hinder Wi-Fi connectivity:
NOTE
The Power Factor is calculated based on formula PF = (Real Power) / √ ((Real Power)2 + (Reactive Power)2)
