Getting a 5.8GHz mmwave sensor to reliably work

Houston…

I think I messed up and it’s too late to return the device…

I got this device a while back and set it up with the following code in ESPHome:

esphome:
  name: sensor-presencia-58-v1
  friendly_name: Sensor Presencia 58 v1

esp32:
  board: esp32dev
  framework:
    type: arduino

# Enable logging
logger:

# Enable Home Assistant API
api:
  encryption:
    key: !secret api_encryption_key

ota:
  password: !secret ota_password

wifi:
  ssid: !secret wifi_ssid
  password: !secret wifi_password

  # Enable fallback hotspot (captive portal) in case wifi connection fails
  ap:
    ssid: "Sensor-Presencia-58-V1"
    password: !secret fallbackap_password

captive_portal:
    
    
uart:
  tx_pin: GPIO22  
  rx_pin: GPIO23  
  baud_rate: 115200  

binary_sensor:
  - platform: gpio
    pin:
      number: GPIO21  
    name: "Detección de Movimiento"

It works, but I thought mmwave was supposed to even see me breathing… which this doesn’t… I basically have to move even more than if I had just a simple infrared sensor…

Is there anything I’m doing wrong? Or is it that I just got the wrong device?

I currently have it at about a meter in height (about 3ft) just for testing purposes…
