Hello,
does anyone have this option installed? are you using two uart ld2410 sensors on one esp32?
can you please show your yaml?
I need to know exactly how to make it work. Ideally with the possibility to edit the parameters of both ld2410.
Thank you very much
Use different pins.
And remember that ESP32- S3 might only have 2 hardware UARTs, where ESP32-S2 have 3.
One is used for the logger, so if you do not disable the logger, then one of your extra UARTs might be a software one, which is prone to data loss at high speed connections.
But I need to see the yaml. that I have to use other pins is perhaps clear
Post your YAML of your first UART setup.

First you need to research your board a bit.
A pinout description and picture is a good thing, because that will tell you what pins are available to use.
If you can find a description with what pins are floating or have weird behavior at boot, then it would be great too, like this one: ESP32 Pinout Reference: Which GPIO pins should you use? | Random Nerd Tutorials
Once you have that, then you need to select RX and TX pins for the extra LD2410.
When those are selected then you need to state ids in the different sections, so ESPHome knows which one to use.

Here the uart, ld2410 and a select section have been set up. You need to add the ld2410_id entry to all your other references to the ld2410 and then doublicate it and rename that ld2410_id entry for one of them to get your double.
BEWARE! The pins I set for uart_2 is just some random ones. I do not know if they work, so do the search on the net for your board.
this is exactly what I needed to know. Thank you for your help. I’ll try it and see if it works
hi, so I tried it, but your suggestion doesn’t work. Please send me your yaml, let me try to edit it. Thank you.
I do not have have those sensors set up through UART.
You can get my UART set up from my Onkyo Amp, but it is only the UART setup I need for that.
okay, stick it up 
This is my use of UART.
