Hi folks! This project sounds so awesome that I decided to build my own. I had some pcbs made and I assembled 2 boards. I’m handy with soldering and burning bootloaders and uploading code, so my EmonPi v1.6 pcbs are good to go, but I chose not to populate the wireless radio portion as I won’t be using any external nodes/sensors.
I successfully flashed the Uno bootloader to the 328, and used an FTDI cable to successfully upload the code (from the firmware folder) to the 328 after that. I guess this second part wasn’t needed as the pi will upload that code for me when running the updater…(?)
My questions are, do I NEED the wireless radio? My dashboard doesn’t show any inputs available. but now I believe I’m missing the next part:
Do I need to power the Raspberry Pi 3 via 5v usb plug AND the EmonPi pcb via 5v usb? Wouldn’t one power the other? So far I’ve just been powering the raspi via usb plug. I see that per the schematic, this is not true…wouldn’t that be an easy thing to do? I’m thinking that maybe powering the EmonPi pcb will power the raspi (have yet to try that; will do that when I get home tonight).
Thanks for this great project! The support is awesome, too
