Nathaniel Elijah has posted the a complete working prototype of an EFERGY E2 CLASSIC Transmission decoder using a Raspberry Pi and RTL-SDR USB Dongle. The EFERGY E2 Classic is an electrical usage monitor which displays information received from associated wireless energy sensors. Nathaniel writes, “It is now possible to capture those 10s to 20s power consumption samples or Efergy E2 Transmission raw data through use of a RTL-SDR USB dongle connected to a Raspberry Pi. The R-Pi runs on a Fedora Linux OS with the C code decoding software installed.”
