Screek presence sensor (sub.wetshaving.social)

I'm using a run of the mill motion sensor in the living room that turns the lights off after a certain duration of no motion (unless the TV is on). Sometimes the lights turn off when I'm still in the room because I'm stationary.

I know people seem to like the mmWave sensors for this and I'm considering getting a Screek 2A from eBay.

I'm curious if anyone here has used one. Thanks!

I’ve got two of the Screek 2A sensors and think they’re good. Mmwave technology isn’t a magic bullet that automatically works every time, like all radio tech there are some limitations.

I use one to turn on a light in a hallway and the other to detect when someone approaches the front door and issue an alert via ntfy.sh. Once in a while it misses some motion, so I’d probably not recommend it if you were building a human life kind of scenario, but they’re fine for me.

More importantly, they’re well supported by HA/ESPHome, open source, inexpensive and compact.
