I have LD2410 in a small PLA case. I made front plate pretty thin (1mm) and i didn’t notice and degradation in range. I guess it’s a good idea to leave as little as possible between sensor and front plate, to eliminate any reflections, though.
Did you manage to fix this? I’m having the same issue.
Switch TX with RX.
Had same problem.
I see lots of posts/people saying to connect RX to RX and TX to TX. Not in my case.
I’ve seen the same thing. However, I don’t think that is correct. Usually transmit (TX) on one end connects to receive (RX) of the other Since I’m using a D1 mini (esp8266) and powering through the USB I’ve read that this may disable the RX pin which is why I moved the pins. However, I’m using Uncle Yura package and if his solution is hardwired to pins 1 & 3, that would explain why it doesn’t work for me. My next step is to use an ESP board vs the ESP8266.
I am using D1 Mini+LD2450+Yura package, and yes, I had to to connect TX-RX and RX to TX to see data coming in(the logic thinking).
But in another project I use a RS485-TTL converter (3.3V), and in that one I had to connect TX-TX and RX to RX. Also in that converter I cannot use UART pins due to pull ups, so I choose D2-D1 as UART
Yep, I tried, it is 50/50, on one it is working great, on other 2410 went crazy, however if I switch 2410 to low distance settings it is always working correctly.
I tried it multiple times, even with ld2450, I asked them to enable cloud point instead of processed data (as it is in LD6002), they promised and nothing happen for months

just wondering if there is an alternative way to integrate this kind of sensor in HA without using esphome…
i commonly code my ESP devices and then use mqtt integration to take data to my HA, but i think there is not a “mqtt presence sensor” in ha, am i wrong?
half of the fun is gone if i use esphome 
binary sensor with device_class presence
Most often I am using TCP/UDP UART proxy

well i assume this is just a… binary sensor so no “radar”, no x-y-z values and so on…
what about this?
it is just a device with multiple sensors, presence is binary sensor, x,y,z are numeric sensors etc.
ad UART:
I am just getting stream and parsing it locally, in python or js (node red)
Then when I am happy with solution I am writing C code for esp or for esphome.

I finally got mine as well. Tested 4 diffrent ld2450 and 4 ld2410. Distance between sensors 4cm and never got bad readings. Maybe it’s firmware issue or orientation (my ld2450 is vertical, ld2410 horizontal) which causes problems.

Have you tried LD2450 with multi-target mode? In my case, the reading is not stable. 2 actual target become 1 target by reading data sometimes and 1 actual target become 2 target by reading data sometimes. total 10pcs LD2450 I have and all of them have same problem in multi-target mode. single target mode is no problem. (my LD2450 is vertical too).
so far, only LD2410B/C is OK for me due to its sensitivity can be adjusted. it should be better if LD2450 and LD2461 can be adjusted too. after all, the environment is a variable. of course, this is just my personal opinion!

Ihave being trying to display the correct measurments using everything lite code, but I always have x10 report.
Cannot find where the issue is.
Radartool is in meters, but no matter what I type in code, I am always x10 off.
In picture I should have been at 69cm not 699cm.
If I change to mm in code, I will be at 6,999mm.

Radatool is OK…
Example:
When at 4.6meters it reports the correct distance.
Need help.
What should I change, and where?
Hi, i installed the sensor and it look like its working with firmware 2.04. I have read that i need to downgrade it, but my app ist crashing while downgrading. Is this normal? Tried two LD2450.
But i have one problem: i create a custom zone on uncle-yura firmware and it fires correct, but only for around 2 Seconds, then its back to no presence. This will start a endless cycle an my lights are “flashing”
It also looks like “ignoring” in Redion iss working correctly, but “detect” is not.
Inside the app location look fine.
hi, do you have a link for that?
No anwsers, so I had to ask chatgpt for help
Use p1_x /= 10; and p1_y /= 10; etc etc to divide by 10 all x and y values.
Example for P1:
int16_t p1_x = (uint16_t((bytes[5] << 8) | bytes[4] ));
if ((bytes[5] & 0x80) >> 7){
p1_x -= pow(2, 15);
}else{
p1_x = 0 - p1_x; // was 0 - p1_x;
}
p1_x /= 10; // Divide by 10
Now I have the correct measurements for each x/y and distance

Where can I find a working ESPHome configuration for LD2450?
