Success! Here is how I was able to move a Hue bulb to HA in ZHA: open up your Zigbee device in HA and add a new one so it’s in discovery mode, then delete the light from the Hue app and it will show up in about 10 seconds.
I know that sounds simple but I went through a lot of trial and error to get to that. I had a previously deleted bulb that just wouldn’t get discovered by Zigbee no matter what I tried so I added it to the Hue App and immediately deleted it and it finally worked. I haven’t played with it much as native Zigbee but this gives me hope!
I’ve read that it’s in paring mode for a very short time, but that doesn’t seem to be the case when you just turn it on, and perhaps its because mine was paired in its past and a brand new bulb will pair up right away.
It looks like a fast color loop is all you get for effects, so I’ll have to see if theres a blueprint or something for a less spastic color change or create my own. But so far it’s fine.
