RTSP - No smart (AI) motion events passed, only general (all) motion?

[Autopilot]

I’m using 811a’s and Duo 2 POE with the 8ch NVR. All with latest firmware. 

I use Scrpyted to add my cameras to Homekit using RSTP, which generally works OK.

However the NVR never passes smart motion events, only ‘general’ motion. I had set general motion sensitivity  to ‘1’ as I am only interested in smart motion events (people/vehicle) because I don’t want constant false arts turn the camera spotlights on.

If I turn motion sensitivity up to 30, then general motion is detected by the camera/NVR and passed to Scrypted and HVS recordings are tiggered fine.

Is this how it meant to work, or should smart motion events be passed on via RTSP/Onvif?
