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.
So you'll never get a real insight into the actual generated energy and the actual consumed energy. You can also measure the generated energy (apart from the Smart Meter) with aAC 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.
