[BUG]: wrong unit

Describe the bug.

The 'Energy Used' entities both have the unit 'Watt' , I think the correct unit is Watthour (Wh).

Solution:

In Sensor.py, add ENERGY_WATT_HOUR:

from homeassistant.const import (LENGTH_KILOMETERS, PERCENTAGE, POWER_WATT,
PRESSURE_BAR, SPEED_KILOMETERS_PER_HOUR,
TEMP_CELSIUS, TIME_SECONDS, ENERGY_WATT_HOUR)

and change native unit of measurement here:

SensorEntityDescription(
key="total_energy_consumption",
name="Energy used (total)",
native_unit_of_measurement=ENERGY_WATT_HOUR,
device_class=SensorDeviceClass.POWER,
state_class=SensorStateClass.MEASUREMENT,
),

and here:

SensorEntityDescription(
    key="average_energy_consumption",
    name="Energy used (average)",
    native_unit_of_measurement=ENERGY_WATT_HOUR,
    device_class=SensorDeviceClass.POWER,
    state_class=SensorStateClass.MEASUREMENT,
),

Needs some more changes: is using native unit of measurement 'Wh' which is not a valid unit for the device class ('power') it is using; expected one of ['W', 'kW']; (easy fix though)

Fixed in v0.2.7 although it requires to dump the old data ... other approach would be to introduce new names (and you'd have to manually delete the old ones).
