Has anyone a working yaml file for NodeMMCU v3? Both of the above configs are not working for it.

@CTEBAvuk Thank you very much! Your suggestions worked fine with my D1 mini.

I still cannot be able to get my Esp Vroom32 to work, all configs came out Unknown for my sensor, anyone have the same issue :(?
Nvm swapped out the TX and RX pins, it works now.

Can I get zone options in this?

Swapped out in which way?

Hello. This Yaml code that you published is fine for D1 mini right?

I've try different Yaml files and still getting Unknown I'm using D1 mini and LD2410c , I have confirmed my wiring is correct but no go

any ideas

I get this message, I can count on help,
ERROR Running command failed: device reports readiness to read but returned no data (device disconnected or multiple access on port?)
ERROR Please try running esptool.py --before default_reset --after hard_reset --baud 460800 --port /dev/ttyUSB0 --chip esp32 write_flash -z --flash_size detect 0x10000 /data/build/ld2410-esp32/.pioenvs/ld2410-esp32/firmware.bin 0x1000 /data/build/ld2410-esp32/.pioenvs/ld2410-esp32/bootloader.bin 0x8000 /data/build/ld2410-esp32/.pioenvs/ld2410-esp32/partitions.bin 0xe000 /data/cache/platformio/packages/framework-arduinoespressif32/tools/partitions/boot_app0.bin locally.
INFO Upload with baud rate 460800 failed. Trying again with baud rate 115200.

It doesn't work for me either using a D1 Mini and the LD2410 without Bluetooth. I also get "Found no i2c devices!" so disabled that already as well as "platform: bh1750" that wasn't detected either

This is most likely because the device uses the same rx/tx as the usb. Try flashing a base ESPHome firmware before attaching the device. Once flashed, you can perform subsequent updates via OTA updates.

I managed to get it working using a D1 mini and a LD2410 , the Yaml files is below
