Would this work with a mesh router?
replies(1):
This is an open-source (GPLv3) project that uses Wi-Fi signal analysis to detect motion using CSI data, and it has already garnered almost 2,000 stars in two weeks.
Key technical details:
- The system does NOT use Machine Learning, it relies purely on Math. — Runs in real-time on a super affordable chip like the ESP32. - It integrates seamlessly with Home Assistant via MQTT.
- It monitors CSI from that specific node (the one it's associated with)
- If the ESP32 roams to a different mesh node, it will start monitoring CSI from the new node
The system doesn't care about the router's internal mesh topology, it just needs a stable connection to receive CSI data from the associated access point.
So you might have an ESP32 placed across the room from one mesh node to monitor that particular room. But if that ESP32 roams to, say, the mesh node on the floor above it, it's going to monitoring a much less useful space - just the vertical space between itself and the mesh node on the floor above.
Am I envisioning this correctly? I'm thinking its a problem for systems like eero, where you can't lock a device to a particular mesh node.
