Although it came in as an unknown node, it did create a light entity and I am able to control the bulb via Home Assistant. I had to change the “supported features” component of the entity to get access to the white level. See this post for details on how to do that: [HOME ASSISTANT LIGHT - SUPPORTED FEATURES](RGBW bulb in Home Assistant? Ask the Community RGBW bulb in Home Assistant? - #4 by kloor)
I’d recommend excluding and then re-including the bulb, I’ve seen something like that happen before when something goes sideways during the inclusion process.
