I don’t know anything about Ring bulbs, no user has ever reported anything about them and I have no idea how they appear in the API. I was under the impression that they still required being paired with a Ring Bridge, and thus would likely work as any other Ring Smart Lighting device, but it’s possible they have their own device type, however, even if this is the case it should clearly show in the addon logs as finding an unsupported device. Feel free to open a discussion or an issue on the project page and we can dig deeper.
