[BUG] Images don't seem to work

[mo-seph]

I've got several entities working on a device (Buttons, Sensors etc.), and they all get picked up by Home Assistant:

I've added an Image to this, but it doesn't show up as a control, and it doesn't appear as an image entity that I can put into dashboards.

I can see the MQTT messages coming through:

topic:
homeassistant/image/Drawbot/Image/config
payload:
{
  "component": "image",
  "device": {
    "name": "Drawbot",
    "model": "fake",
    "identifiers": "drawbot"
  },
  "icon": "mdi:image",
  "name": "Image",
  "unique_id": "drawbot_image",
  "payload_available": "online",
  "payload_not_available": "offline",
  "state_topic": "hmd/image/Drawbot/Image/state",
  "json_attributes_topic": "hmd/image/Drawbot/Image/attributes",
  "command_topic": "hmd/image/Drawbot/Image/command"
}

and

topic:
hmd/image/Drawbot/Image/state
payload:
https://www.google.com/images/branding/googlelogo/2x/googlelogo_light_color_272x92dp.png

So it looks like MQTT is being sent, but HA isn't picking it up as an entity?

Ok, that's weird. I haven't done anything with images myself, I'll try to look at it this weekend.

From the Image docs (https://www.home-assistant.io/integrations/image.mqtt/) it looks like url_topic or image_topic (for supplying bitstreams) would be the right field in an Image, rather than state_topic. I haven't quite understood the library structure well enough to poke at that myself.

@mo-seph You are correct, here is some sample code which is using the state_topic as url_topic. Of course this is only a hack and I am working on a proper fix:

import asyncio
import logging

from ha_mqtt_discoverable import Settings, DeviceInfo
from ha_mqtt_discoverable.sensors import ImageInfo, Image
from paho.mqtt.client import Client, MQTTMessage

logging.basicConfig(level=logging.DEBUG)
logger = logging.getLogger(__name__)


def my_callback(client: Client, user_data, message: MQTTMessage):
    pass


async def main():
    mqtt_settings = Settings.MQTT(host="192.168.0.216",
                                  username="someusername",
                                  password="somepassword")
    device_info = DeviceInfo(name="Drawbot", identifiers="unique_device_id")
    image_info = ImageInfo(name="Image",
                            device=device_info,
                            unique_id="unique_image_info_id",
                           url_topic="hmd/image/Drawbot/Image/state")
    settings = Settings(mqtt=mqtt_settings, entity=image_info)
    image = Image(settings, my_callback)
    image.set_url("https://octodex.github.com/images/baracktocat.jpg")

    while True:
        # update image here
        await asyncio.sleep(1)


if __name__ == '__main__':
    asyncio.run(main())

It is supposed to look like this then:
