Efergy e2 classic (electricity meter).

This electricity meter periodically reports current power consumption on frequency ~433.55 MHz. The data that is transmitted consists of 8 bytes:

Byte 1: Start bits (00)
Byte 2-3: Device id
Byte 4: Learn mode, sending interval and battery status
Byte 5-7: Current power consumption
- Byte 5: Integer value (High byte)
- Byte 6: integer value (Low byte)
- Byte 7: exponent (values between -3? and 4?)
Byte 8: Checksum

Power calculations come from Nathaniel Elijah's program EfergyRPI_001.
