The sensor.total_power entity does not initialize after stopping all devices

[YoppY14]

When solar overflow is no longer sufficient to activate any of the devices configured in Solar Optimizer, the integration should stop all devices and, subsequently, set the sensor.total_power entity value to 0 or null since no device is active anymore. However, this sensor does not initialize and continues displaying the last deactivated device's power value instead.
