A single node does not establish reliable whole-home room location. Signal-based distance estimates are approximate and are affected by walls, placement, device orientation, and radio interference. Some phones and wearables require enrollment or configuration to handle changing Bluetooth identifiers.\u003c\/p\u003e\u003cp\u003eThis is not a motion or mmWave sensor: a person without a supported transmitting device may not be detected.
