Test scenarios - angles, distance, etc.

Hi,
I purchased two of these with the intention of creating some interesting automations (using Home Assistant), based on person count. It is sort of functional, but performance is poor. Essentially, I'm unable to get repeatable accuracy from this. I have tried at a distance (~10-12 feet underneath the TV) and close up (~2 feet on a desk shelf). In both cases the reliability of the sensor is really at the alpha level.

In the 'far away' case, it rarely detects a person and almost never detects both people on the couch (far less than 110 degree aperture). This is straight on (oriented properly per the docs).

The 'close up' case is similar, but If I turn my head during a measurement -- 2 faces detected. This is oriented properly, but about 70 degrees to one side, as my monitor is straight ahead.

I'm connecting to the ESP32 (huzzah32 v2). Both cases are with normal ambient lighting (sun, incandescent, LED, etc.).

Any advice here?

My first thought that comes to mind. Do you have enough lighting in the room so the sensor can see your face.
Im guessing the module doesnt have any own lightsource IR or similiar.
