I read that this is a known issue with earlier releases of the device. Sonoff web site says: If your dongle’s descriptor hasn’t been customed, you can use the tool linked below to change it to “Sonoff Zigbee 3.0 USB Dongle Plus”. If your dongle still can’t be auto-discovered, it may be because your version of Hass hasn’t integrated this feature yet, you can follow the normal configuration steps below. There is a link to the fix on this page:

But another poster said that it has been fixed in a subsequent release. Worth a try though.
