LD2410 esphome tips

hello,

Ble version is great for a standalone use because it doesnt even need to be integrate in HA, only if you need the sensor for automation. It works with a Bluethooth proxy on a dedicated ESP32 : see here to create a bluetooth proxy : https://esphome.github.io/bluetooth-proxies/ and here https://esphome.io/components/bluetooth_proxy.html
Well, it works great, OUT OF THE BOX, i personnaly dont tweak or change anything for a normal use : room of 5m x 6m.
The only problem is when you update Esphome Bluethooth proxy, you need to restart HA to have the sensor alive back, and sometimes redo the integration. But it works, out of the box, you just need to connect +5v to VCC and GND to GND, i take a broken USB cable and cut the micro side and just solder on a connector with 1.24 pitch i bought on Aliexpress (see my pictures or previous posts).

To hook a LD2410 to a Wemos D1 mini, no need for a tutorial to connect 4 pins :slight_smile:
ESP8266 LD2410
5V ----------------------------------- VCC
GND--------------------------------- GND
RX ----------------------------------- Uart-Tx
TX------------------------------------ Uart-Rx

or this :

the advantage is you can tweak everything, but its much bigger sensor and need much power. Very reliable.
