Device does not get created

Describe the bug I run the test script external. I don't know what to use for host. The ip? The ip:1883?

To Reproduce Steps to reproduce the behavior: Run this script on a device which is not the home assistant server. But who is on the same network.

from ha_mqtt_discoverable import Settings, DeviceInfo
from ha_mqtt_discoverable.sensors import BinarySensor, BinarySensorInfo
host        = '192.168.0.216'
mqtt_settings = Settings.MQTT(host=host, username='someusername', password='somepassword')
device_info = DeviceInfo(name="Batteries", identifiers="unique_battery_id")
voltage_sensor_info = BinarySensorInfo(name="Voltage", device_class="voltage", unique_id="battery_voltage_1", device=device_info)
voltage_settings = Settings(mqtt=mqtt_settings, entity=voltage_sensor_info)
voltage_sensor = BinarySensor(voltage_settings)
voltage_sensor.update_state('49.3')

Expected behavior Batteries device should show up in home assistant but it doesnt.

If there is an connection or other error it should show me. But I don’t get any output at all in my python console. No succes message no error message.

Some more tests reveal that the script bbelow works:

    print(f"Connected with result code {reason_code}")
