Using only ESP8266 to read CT and send via Wifi

SCT013-100 Not consistent reading!

I use an ESP8266 primarily for pulse counting on import and generation meters, but I also have a CT sensor to measure household consumption when generation > use. From this experience I can offer the following advice: There is only one ADC on the ESP8266 so you can’t correct for power factor The ADC is 10-bits (like standard Arduino) Although a 3.3V device, the ADC has a temperature compensated Vref of ~1V (I’m using a bare ESP8266 module for minimum cost/footprint, I don’t know if there are …
