- In code: `zeroconf`, `ssdp`, `dhcp`, `bluetooth`, `usb`, `async_step_zeroconf`
- In the UI: Discovered
- Also: discovered

An integration lists in its manifest how its devices can be found, like by mDNS (`zeroconf`), SSDP, DHCP, Bluetooth, or USB. When Home Assistant finds a match, it starts the integration's config flow, and shows the device as discovered.
