Using WiFi signal disturbances to track people might not be super accurate, but damn that’s a cool trick. Although, also a good proof of concept for how bad actors could use nothing but control over a WiFi-capable device to spy on you, which is a bit concerning…
Anyway, before learning about this, I ended up using an ESPHome BLE beacon component along with the Home Assistant app. You can configure the transmission strength in the app, so by setting it to “low” or “very low”, the ESP32 only picks it up when my phone is in the same room. It has worked a lot more reliably than some other stuff I tried.
