I have a NodeMcu v3 CH340; unfortunately, this code doesn't work with it. It's heavy for the 8266 chip.

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

I have a NodeMcu v3 CH340; unfortunately, this code doesn't work with it. It's heavy for the 8266 chip.

Change in the code, what I mentioned below and the code works with ESP8266 D1mini!
In the file given here (attached), you need to change (or add) the following lines:

1.) THESE LINES:
esp32:
board: esp32dev
framework:
type: arduino
CHANGE WITH THIS:
esp8266:
board: d1_mini

2.) Add this line in the OUTPUT section:
inverted: True
After this line:
id: light_output

3.) THESE LINES in the UART section:
tx_pin: RX
rx_pin: TX
CHANGE WITH THIS:
tx_pin: GPIO1
rx_pin: GPIO3

OF COURSE: MUST connect Tx from ESP8266 to Rx from LD2410 sensor, and Rx from ESP8266 to Tx from LD2410 sensor!

With the modifications, the LD2410 sensor works great for me. An example in the attached photo..

Hi,
is it possible to have the sepaat yaml file for esp8266 (d1_mini or similar), because it is not working for me somehow. thank you

Hello! It doesn’t work for me either, all sensors are in the “Unknown” state, despite the fixes. Wemos D1 mini board.

OK. Here is a link to the complete text from the YAML file at the bottom of my post.
You only need to change and enter the name of your WiFi SSID and your password in the text.
And as I mentioned, you need to connect the RX from the sensor to the TX of the ESP8266 and the TX from the sensor to the RX of the ESP8266. And of course, you have to power both devices with 5V (from USB).

YES! I am using ESP8266 Wemos D1 mini and it has been working for me for days, since I modified and posted here.

Download the .TXT file and everything in it, copy it to your YAML file from your ESP8266 that you inserted into ESP Home.

https://www.dropbox.com/scl/fi/g1h9n2jlky3nfjxye3m8p/Za_SLANJE-YAML-za-vezu-Rx-Tx-sa-ESP8266.txt?rlkey=0xxp7ayperw31gk6ehw0rkpgb&dl=0

...and an example of how it works Wemos D1 works for several days with the LD2410 sensor, without interruption.

I had problems with the ESP32 and it used to turn out to be unavailable, unknown, etc...

I found the fix for the ESP8266 from the esphome page about the Ic2: https://esphome.io/components/i2c.html
sda (Optional, Pin): The pin for the data line of the I²C bus. Defaults to the default of your board (usually GPIO21 for ESP32 and GPIO4 for ESP8266).

scl (Optional, Pin): The pin for the clock line of the I²C bus. Defaults to the default of your board (usually GPIO22 for ESP32 and GPIO5 for ESP8266).

So my fix was to do this:
i2c:
sda: GPIO4
scl: GPIO5
scan: true
id: bus_a

hope that helps someone

So I have read a lot about the LD2410C and The ESP8266, and i am by no means a coder, but i do manipulate code, so this is what i have found
Set up your ESP8266 inside ESPHome in Home Assistant as a straight forward new clean device.
Then go into edit and after the line captive_portal: leave a line space and paste the following code

How there will need to be some changes
tx_pin: 1
rx_pin: 3
change these setting to suit yourself (1 and 3 are where i put mine)
I also removed the part about "Illuminance" as i believe this is only needed if you have a bh1750, which i dont and to be honest, i think there is a few other lines that could be removed Like mac address, but i left them in , they dont seem to be an issue

So this should fix the sda: and scl:, the fact that the blue LED was off when on and on when off, and tx and rx pin.
as said earlier in this thread, but i will say it again

OF COURSE: MUST connect Tx from ESP8266 to Rx from LD2410C sensor, and Rx from ESP8266 to Tx from LD2410C sensor!

If anyone understands what the light threshold, and out pin level function means, i would appreciate that.

anyway, hope this helps/

Hello folks!

This is the code I'm using and work's perfectly with esp8266. The inconvenient is that you don't have granular control on the distance gates. You set the same threshold value for all of them.

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
