RuView
WiFi channel-state sensing for presence, breathing, and pose without cameras
What it is
RuView reads Channel State Information from low-cost ESP32 sensor nodes and infers room occupancy, movement, breathing and heart rate, falls, and approximate body pose from how people disturb WiFi signals. It includes ESP32 firmware, signal-processing and model-training code, pretrained models, and bridges to Home Assistant over MQTT, Apple Home, and Matter. Smart-home tinkerers and researchers use it to add camera-free presence and vital-sign sensing to rooms, with automations built on states like bed exit or inactivity.
