Flex_led device without entity_id

I have a integration into a single Magic Home led controller through the flux led integration:

  - platform: flux_led
    devices:
      192.168.21.7:
        name: bedroomled
        mode: "rgb"```

The device appears on the overview page and I can control the LED strip directly. But I am unable to use the integration in any automations. The integration does not have a Unique ID. 

I have tried a customisation:
https://www.home-assistant.io/docs/configuration/customizing-devices/



```''light.bedroomled:
  entity_id: ledstrip1
  unique_id: ledstrip1
  id: ledstrip1''```

Zero impact. 

Anyone have any ideas?

flux_led is getting a config flow in 2021.11, and these devices will now have unique ids .
