Hello this is my first post, thank all for make this awesome project.
I am trying for a few days, make a pulse sensor in a nodemcu esp-12 board collect & process data from Adc (analog input) and GPIO and integrated in EmonESP firmware. But i cant, only i did this attacht arduino nano to nodemcu (EmonESP) by serial, this run OK.
I want make via EmonESP firmware, because two components it is unnecessary and redundant since the nodemcu has capacity for it.
