DSMR Logger V4 (Smart Meter Reader)
Placed onADC interface
A major disadvantage of the Smart Meter is that it sums the energy of the solar panels with that of the consumers on the same group.
This way you never get an insight into the energy actually generated and the energy actually consumed. You can also measure the generated energy (outside the Smart Meter) with a AC Current Sensor (e.g. an SCT013-030 or ECS1030-L59). You clamp these around the phase wire of the solar panels entering the meter cupboard and they emit a voltage that depends on the current that runs through the cable.
ADC Circuit For the use of these types of sensors, the ADC (Analog to Digital Converter) pin of the ESP8266 is extremely suitable. In the schematic of the DSMR logger v4, it has a range of 0-5volts. By R12 and R13 (5% tolerance, a smaller tolerance is better) you can change this range.
