I’m trying to remove the Hue bridge from my home network but can’t seem to get Home Assistant to find the bulbs over Zigbee. Even the Hue app can’t find them unless I use the “use serial number” method.

• I deleted the lights from the Hue app
• I factory reset the lights (using dimmer switch method)
• I clicked “add device” in home assistant… aaand nothing. Just “Searching for Zigbee devices…”

I thought the problem might be wifi interference but I turned off my 2.4ghz network and still nothing.

I have other Zigbee devices successfully connected to my dongle, (Sonoff) and I can pair the bulbs with Hue bridge, but only using the serial number method.

Any ideas as to what might be going on?
