Sensor init fails if unit of measurement is a string #326
Description
When providing a unit in the tuya V2 quirk builder that is a string (instead of an Enum) the sensor init fails.
I used the unit lx, which is defined in the const LIGHT_LUX
.tuya_sensor(
dp_id=101,
attribute_name="measured_value",
type=t.uint16_t,
fallback_name="Illuminance",
device_class=SensorDeviceClass.ILLUMINANCE,
state_class=SensorStateClass.MEASUREMENT,
unit=LIGHT_LUX,
)
