UNDER DEVELOPMENT
Just using your original Efergy product and a Raspberry Pi you will be able to monitor your consumption, have statistics and know how much kWh did you waste.
Checked in a Raspberry Pi.
Requeriments:
Just to get Laravel working: Apache Php5 Mysql
To take data: Download my fork RPI_Efergy, that will store some data directly into your Mysql.
How to start capturing data?
modprobe -r dvb_usb_rtl28xxu; rtl_fm -f 433.54e6 -s 200000 -r 96000 -A fast 2>/dev/null | /home/pi/scripts/RPI _Efergy/EfergyRPI_mysql;
note that 433.54e6? thats my best freq, you will have another, check the RPI_Efergy readme to know it.
