Quick verdict
The UDM-Pro is the heart of a UniFi network and, for Home Assistant, the controller that the local UniFi Network integration polls. That makes it superb for local presence detection - every client device shows up as a tracker - while keeping data on your LAN. In Home Assistant this surfaces through the local UniFi Network integration as a monitored network device plus client device_tracker entities for presence detection. It is reliable, fully local monitoring, but note HA treats it as a network device to watch, not a controllable smart-home device.
Standout: Runs the UniFi Network controller itself, so it is the hub Home Assistant's local UniFi integration talks to for whole-home presence detection.
