  Open this website on your desktop using Google Chrome or
• ○
  Microsoft Edge.
• ○
  Connect the ESP32 via USB to the PC where you open
• ○
  ( ESPHome Web ) and perform the first setup of the ESP32
• ○
  module.

• ○
  LD2450 Configuration
• ○
  The following data must be filled in

  Entity Name:

  Encryption Key (optional):

  Number of Detection Zones: 1 - 10

• ○
  On this page you can generate settings for (LD2450)

• ○
  The LD2450 configurator generates three files.

• ○
  Save all three files.

• ○
  You need to add the YAML file to the ESP32 module's base YAML file.
  

• ○
  Save the Zone H file to the ESP directory in the Home Assistant app.
  

• ○
  In order to use the Plotly Graph file, you must have downloaded the Plotly Graph card from HACS.

• ○
  Now we need to edit the dashboard and add a new arbitrary tab and show the code editor and paste the code from the Plotly Graph file. Save and we're done.

• ○
  And now you can create conditions, triggers, automations, etc. in the zones you created. Good luck :D
