I have recently bought an emonTx kit complete with ESP8266 board, CTs and pulse sensor. Everything is setup and working well but the pulse counter is intermittent, despite the green sensor LED always counting perfectly in time to the meter LED.
The pulse sensor is connected to the emonTx via a 1.5m standard RJ45 extension cable. Am I experiencing some interference/voltage drop that could be causing the emonTx to not count the pulses? Is there a different type of sesnor I could try? What’s the best way to extend the sensor cable that wouldn’t impede performance?
