Has anybody managed to get the LD2410 working with the ESP32 minikit?
anyone was able get LD2410C to work with esp32 devkit v1 30pin ? I am getting unknowns for all the sensors. please send me the config and let me know which pins for TX and RX. Thanks!
I have it working with ESP32 Wemos D1 Mini. Nothing special that I recall while configuring it:
i2c:
sda: 21
scl: 22
scan: true
id: bus_a

id: ld2410_uart
tx_pin: RX
rx_pin: TX
baud_rate: 256000

stop_bits: 1

light_function:

out_pin_level:

This is the part of the configuration relative to the connection between the ESP32 and the LD2410. In your case I think you should use pin 42 por SDA (gpio21) and pin 39 for SCL (gpio22)

Thanks - I am going to try it. how do you decide to use PIN 39 and 41 instead of 25,27 for RX / TX? I used the latter because I assumed those are TX.RX pins
I’m really struggling to get the LD2410 to work for automating my lights. I’ve fitted it in an existing PIR and it all works but a little TOO well unfortunately.
I’ve done the calibration for the room and it all works perfect but then… it keeps detecting people in the next room and the floor above. Making it less sensitive means it doesn’t work as it should when I’m actually in the room so I’m a little stumped on how to proceed from here. Any tips?
turn the sensitively down or reduce the distance so your not picking people up in other rooms
The LD2410 can be tweaked quite extensively and can take some time to tune but once tuned, works very well.
You can change the number of gates used and that will reduce the effective detection range.
You can also adjust the still and movement thresholds for each gate and that will determine how much movement will trigger the detection for that gate.
A value of 100 will effectively turn off the detection of the gate and 0 means it will detect all the time. Finding the right balance will allow it to detect the desired movement and eliminate false detections.
I believe I copied the configuration from somewhere and then wired the ESP acording to this configuration. Worked fine from the begining…
In my case I tweaked the number of gates and then prepared a dashboard with some custom sensors that triggers when presence is detected in each gate so it records the value that made it trigger. The first step I took was to leave it enabled during the night when I know there should be movement only in the bedroom so I can filter every detection (false positives) during this period increasing the threshold of the gates that triggered. Repeating this (careful with the logs generated while engineering mode is enabled) in different situations can lead to a pretty polished detection ranges and minimize false positives while keeping the best possible detection sensitivity.
I’m using two LD2410c sensors in my garage, one at the dooropening where the light switch would be and one integrated in the casing of my alarm motion sensor, this way the garage is completely covered.
I’ve found that the minimum sensitivity (in my case) is 15, anything below results in false triggers.
I’m using all 8 gates and don’t have any false triggers.
but just out of curiosity, the lights in my garage are controlled using a relay connected to an espboard and is triggered by the ld2410 sensors, the opening of the garage doors, etc…
is there a way to delay the relay when turned off for x time before to be able to turn back on? like a condition when the relay is turned off it has to wait x seconds before it can be turned on again? (not a delayed turn on, the relay must be turned on immediately when triggered and the wait condition is over)
Hello all!
Not sure did someone manage to do it or not, but i’m trying to set up my esp32-c6 and ld2410C to report via MQTT.

It’s not reporting anyting at all, and there is nothing in the logs
The only thing that it’s reporting is the wifi stuff
Any idea what may be the issue?
Hey @Still_ill how did you get the lux value reading?
I’m going nuts as the BH1750 sensor does not return any value, it’s unknown state!
Don’t know about c6
But made mqtt for my s2 (using API for now)
But if i’m correct - you don’t declare “state_topic” for values to publish.
This is just part of code, I have all substitutions in separate yaml.

Many many thanks for sharing, I’ve just used the i2c code modified as follow to match my esp32 Wroom-32D board but still getting no results

I’ve just one Dupont to connect to the out pin on the ld2410c so tried both on SCL and SDA but not working.
Sorry if it sounds like a noob question but I’m approaching HA and the ESP32 world in these very days, read a lot but am practicing now!
Any tip?
Ok, you have used GPIO 21 and 23, which is good. I can’t see anything wrong with that either. Where did you connect your ld2410? These must be cross-connected to tx and rx. On the Esp32 and should be GPIO 17 and 16. But better check this again.
yep they are cross connected and all the entities on the ld2410c are working just fine but the infamous illumiance sensor!
Can’t figure out why!
Maybe is something with the soldering of pins from the BH1750. If you have the possibility to check with another BM1750. I had also problems with this sensor. After resoldering the pins everything works fine on my end.
I agree with itapower: In this case, I would check the soldering or test a new sensor directly. The configuration looks flawless to me
I have range problems with my ESP32 Wroom-32 LD2410C solution.
Soldered 5V, GND and TX, RX (Pin 16, 17) together and booted up next to my HA Server, it works just fine.
In my floor, round about 6m away, with 2 walls in between, I do not get a connection. I tried a bluetooth proxy and also a ESP32 Repeater to bridge between server and LD2410, but I am still not successful.
Can someone explan me, if the LD2410 works via Wifi, when connected to an ESP32 or still via the BT of the ESP?
What is the best strategy to hit the range problems?
