SensorRegistrationInfo is the JSON structure required to register a sensor with HA.

SensorUpdateInfo is the JSON structure required to update HA with the current sensor state.

SensorDeviceClass reflects the HA device class of the sensor.

SensorStateClass reflects the HA state class of the sensor.

SensorType reflects the type of sensor, sensor or binary_sensor.
