That is very interesting especially the presence bit, since outside of cameras or well placed pressure sensors, this seems to be one of the few elusive bits of data in HA.
Not sure how it can do all of that using radar though unless it is doing something like SLAM LiDAR but never seen anything like that in this small of a package, and at that point you might as well do computer vision. Breathing detection is especially suspect imo.
If this works for presence and radar is decently battery efficient I see a future of combo radar/pir motion sensors, assuming that pir is more accurate and less power hungry for motion.
Couldn’t agree more.
I wonder if there was any demonstration of this thing in action?
