First device:

Paired ikea tradfri switch with it. Took few mins (and dev appear/disappear), and then zigbee2mqtt showed the switch as paired.

Enable homeassistant boolean in zigbee2mqtt yaml, after which it zigbee2mqtt published info about switch in mqtt. That mqtt discovery message was picked up home assistant and appeared as a device in MQTT integration. The friendly name configured in zigbee2mqtt web frontend also appeared in home assistant.
