Quick verdict
Apollo's flagship presence sensor: a ceiling-mount mmWave unit powered by a single PoE Ethernet cable, with one radar included (LD2450) and room for an optional second radar (LD2412). The detection accuracy is a step above USB-powered models, and the ceiling placement eliminates the blind spots you get with desk or shelf mounting. It is overkill for a single room, but for whole-home presence tracking on a PoE backbone, nothing in the ESPHome ecosystem matches it.
Standout: PoE ceiling-mount mmWave presence sensor - ships with one LD2450 radar plus an optional second LD2412 radar for dual-radar sensing. Apollo's most capable.
