mmWave radar: raw data access & SDK usage?

Hi all, I’m specifically looking into mmWave radar beyond standard Home Assistant integrations. Has anyone here worked with raw radar data from mmWave sensors and used a vendor SDK or custom processing pipeline ?

  • Which sensors/platforms actually expose usable raw data?
  • Did you use vendor SDKs (e.g. HLK, TI, etc.) or your own algorithms?
  • How does the accuracy compare with the built-in (black-box) presence detection?

I’m less interested in out-of-the-box HA integrations and more in low-level access + algorithm flexibility. Any experience or pointers would be really helpful. :blush:
