ESP32-S3 with LD2420

ESPHome
1

Hello there,

I’ve been trying since hours to get the LD2420 working with my esp32.

I tried different configuration but it always say, LD2420 marked as failed.

I’m thinking that something is working with the pins.

Does anyone have an ESP-S3 with an LD2420 working? And could tell me where I have to set the pins and how to change it in the config?

I’m quite sure you find better support here if you post your wiring and your yaml to start with…

I made it to work, it was just the code.

text_sensor:

  • platform: ld2420
    fw_version:
    name: LD2420 Firmware

  • platform: ld2420

    name : Moving Distance

binary_sensor:

  • platform: ld2420

switch:

  • platform: restart

Great!
Next time you post code, use code tags. Click that gear icon on top right and select “Preformatted text”. So the code presents like this:

text_sensor:
  - platform: ld2420
    fw_version:
    name: LD2420 Firmware

sensor:
  - platform: ld2420
    moving_distance:
    name : Moving Distance
