Get the B variant, you can configure it over Bluetooth from your phone. Otherwise it's a huge hassle.
That said, it doesn't work very well for me when sitting still 4-5m away, it thinks I've left.

These radars are designed to detect motion, not someone sitting still.
Wrong, most of these radars are 24Ghz and specifically designed to detect body micro movements. They specifically give both human 'occupancy' and dynamic ranging information.
I wrote low level drivers for the ESP32 for all the ones I could buy and have tested all of them. The only one that does not try to give a human occupancy position is the car speed sensor.
The ld2450 can track three people at once.

This sounds very interesting, how do your drivers work? I'd love to try them out, but there's no documentation. I've made a sensor board with various sensors, I could really use some occupancy detection improvements on the LD2450B.
