Smart home WiFi - human presence monitoring

WiFi-Based Spatial Intelligence

The RuView platform is highly valuable for "home-as-a-robot" and elder care because it transforms low-cost, commodity WiFi signals into a comprehensive, contactless spatial intelligence system that operates entirely without cameras or wearables. By utilizing radio wave disturbances (Channel State Information) via $9 ESP32 sensor nodes, it tracks human occupancy, presence, and movement through walls and in total darkness. 

For elder care, it ships with specialized edge modules that monitor continuous vital signs (breathing and heart rates), screen for sleep apnea, and recognize critical events like falls or prolonged inactivity. 

For the "home-as-a-robot" ecosystem, it feeds a unified 3D spatial world model with zero-latency presence data and 17-keypoint body pose tracking. Because it runs entirely on edge hardware and integrates natively with smart-home ecosystems like Home Assistant and Matter, it bridges the gap between environmental ambient sensing and robotics without compromising resident privacy or requiring wearable compliance.

Yes, this is real.    All you need is a few ESP32s scattered around the house.

Philips Hue has this feature built into their controller hub and uses the Zigbee radios already in every Hue light bulb that you already would own and made it work reliably as a commercial product.   So there is no reason to use ESP32, as the software could be built into any wireless device.

But using cameras or mmWave Radar or IR motion detection or even Bluetooth trackers is also easy to do and not expensive and is available off the shelf; no “hacking” is involved.    I mean, seriously, I just bought a couple of mmWave radar units for under $20 each, and they seem to be reliable.  These are finished units sold to end-user consumers, not just the PCB.  One was under $10 but very low-featured.     For more money, I can get one that tracks multiple people.   

For elder care, I’d like to go with BT trackers and make the person wear an ankle or wristband (or a fitness watch if they are mentally up to it).
