Now I am stuck at the next step...

Got a LD2410 presence sensor, connected to my ESP32C3 and found this convenient MicroPython library for it: https://github.com/melastmohican/micropython-ld2410

Got it running easily but it still detects something even if I leave the room. Probably have to find a way to configure the sensitivity via UART? Is it possible I bricked the LD2410 by sending wrong UART codes?

Using a LD2420 instead now, it worked! The presence itself is too sensitive and always is True but I could use the reported distance to detect presence in this room.

Now suddenly it stopped working...
