I’ve had Home Assistant Yellow for over 1.5 years and have never tried Zigbee. I received some Zigbee bulbs today.
My understanding is that Home Assistant Yellow has Zigbee built in. Is that just the radio, or do I also need a hub? The radio appears to be on and working, but not sure what I need to do to add a bulb?
I get a bulb running and it flashes, telling me it’s ready to pair, but nothing shows up when I search for Zigbee devices.
I have Zigbee Home Automation installed. Inside that, it shows 2 hubs: a Generic Zigbee Coordinator (EZSP) and a Silicon Labs EZSP, which is a radio I installed previously when I was unaware Yellow had one built in. It is currently disabled.
Under Device Info for the Generic, it shows:

Let me guess, your old zigbee coordinator was a Sonoff dongle?
ZHA has no idea you’re trying to switch to the internal radio - it’s still referencing the old dongle:
You can only have one coordinator per zigbee integration, and your ZHA install still thinks you’re using the old one.
Change the config of ZHA to point to the internal Yellow radio (you should be able to find it under Settings > System > Hardware > All hardware).
You might have to delete the entire integration, do a restart, then add it back again to be able to use the internal radio.
Deleting the integration appears to be the solution. Nothing showed up when I searched All Hardware for zha, zigbee, radio, ezsp… So I deleted the Sonoff device. When I did that, the information under the Zigbee integration changed, showing Yellow as the hub. Now the bulb is showing up. Thank you!
