I finally got my IKEA bulb added via ZHA. Long story, but needed a better USB extender cable to stop interference.
I thought once I had done that I could install the HomeKit Controller and that would bring in the bulb and then HomeKit Bridge would send it to the Home app. The HomeKit Controller says. No unpaired devices could be found. The bulb did show up in the Home app in the default room, but I am not sure how I got it there. I have done another bulb this morning, and it has not shown up in the Home app.
What have I misunderstood?
