Wanted to try logging to the serial monitor, so trying to compile the esp code using platformio. Is this what you are using ? Or the Arduino platform? As per the readme, I pulled the code, entered the EmonESP folder. If I try just a pio run i am told that there is no emonesp environment, which is true. There is no definition for one in the platformio.ini file - there is in the upstream project. Since this is an Esp32 I changed the default to emonesp32 which does exist and tried to compile again with pio run I then get compile errors
compilation terminated.
