Right now, the JeeLabs Energy Monitor only tracks and reports three mains pulse counters here at JeeLabs. The smart meter’s P1 serial data source will be added soon, but there have been issues with reading it out with only a 3.3V power source - some more experimentation is needed to sort this out.
The next task will be to read out 3 current transformers using the STM32F103’s 12-bit ADC, as well as the AC mains signal, to be able to perform lots of multiplication w/ sums and estimate the real and reactive power consumption for each channel.
