Comcast is promoting WiFi-based motion detection as a part of its new Xfinity Shield home protection platform, allowing routers and wireless devices to detect people moving through a home without cameras or motion sensors.

Looks like it's a feature of the router they provide you if you don't bring your own.

    One more reason I’m glad I bought my own modem and router

    just beware this is their implementation but it is possible to detect movement in wifi signal without special equipment. netgear, tp-link and a few more were found to have backdoors in them for authorized remote access via ssh. opnsense, pfsense, ipfire, openwrt i believe haven't been found to include these backdoors, so basically don't trust any closed/proprietary source routers.

    I, for one, am looking forward to a plugin to do this with OpenWRT and Home Assistant for my own purposes.

    I'm not sure about OpenWRT, but you can do WiFi motion detection with an ESP32.

    Yeah, I found that one. Still, I'd prefer it to be built into my WAPs instead of having to use separate hardware, even if I do have extra ESP32s sitting around.

    I mean, maybe if I could just tack it on as an extra function on some other device I was already going to be using an ESP32 in, but (especially in microcontroller-land as opposed to full preemptively-multitasking PC land) that sounds like maybe more complexity than I want to deal with.
