Efergy e2 data decoding and integration with MySensors
The Efergy e2 electricity monitor (http://efergy.com/it/products/electricity-monitors/e2-classic) provides a sensor that wirelessly sends information about the amount of electricity you are using to the display monitor. The monitor converts this into kilowatt-hours.
