I was unable to get the bulbs to connect to Thread and show up in the Apple Home app despite many tries. After reaching out to support, it took a week to hear back. The initial suggestion was to factory reset the devices (which were presumably already in their factory default state given they didn’t work out of the box). This didn’t work, and it took a week before I got follow up troubleshooting steps. These steps were more detailed, but still didn’t help. After a firmware update, 5 factory resets, and many combinations of pairing via the Nanoleaf and Home apps, the bulbs still aren’t showing up in the Home app and seem to only connect in Nanoleaf via Bluetooth rather than Thread.
