🚨 Heads up, everyone! Since ESPHome 2023.8.1, there's been a breaking change for the LD2410. I've updated the blog post to accommodate both versions: those before 2023.8.1 and those after. Make sure to check the relevant section based on your version for a seamless experience.
Thanks for the great video but I went to the transcript to get the recent esp file, but I don't see how to configure it for the room the way that the old one was done. Where do you set the threshold values?
@@5h4mr0CkThanks for the feedback! Many things have changed since I made this video. You can find all the latest details on the ESPHome page: esphome.io/components/sensor/ld2410.html
I'm planning on filming a new video with the latest changes.
@@SimplySmartHouse hey! any updates on the new video or how to install the sensor now?
The way you break it down fast clear very helpful you HA link helped me a lot installing HA on 10 NUC’s
Great video, thanks! My components arrived yesterday, so I had a go at setting this up today. It was flawless. Had the sensor up and running, and inegrated into HA within 15 mins. Just need to tweek a few settings and it will be perfect. Thanks again.
Great to hear!
Excellent video. Thank you from San Francisco!
Thanks, I’m glad you found it helpful!
Impressive video. Thank you
Thank you!
excelente!!
i got it running thx
Thank you for this
Nice work and waiting for the PIR combined version :)
Sorry, I had to reupload the video, made a mistake with the wiring 🤦
thanks bro i will wait for new tutorial❤
Unfortunately I’m stuck in the “wife approval” part! I don’t have a wife; I hope to solve this problem in a few years and than I’ll come back to this tutorial! Ahaha Great video! Thanks!!
Haha good luck on your journey ;)
Thank you, I'm glad you enjoyed it!
Don’t rush it. Stockholm syndrome doesn’t result in reliable opinions.
@@gilabides Luckily I found a good one! I have to admit that at the beginning it was difficult, everything was pretty awful and sad, but now I love her!.. oh wait..
Ahaha jokes aside, I’m still single. in a few years I’ll switch to plan B: I’ll marry my dog.
I’m currently testing the 1125H and it seems like a great improvement over my 2410C. Give it a try if you can!
Will do, thanks!
Hi Jonatan, i am also the ld2410c ,i using the cable came with it and getting ([22:15:39][C][api:141]: Using noise encryption: YES)
Great job!
Any news about the new tutorial with PIR sensor? 🙂
Took some time off, but more videos are coming up for sure :)
Thank you for this video. I have the ESP Wroom-32 and there is no pin labeled 5v. Can you help with the pin connections for this unit?
I'm glad you found it helpful!
You can use the "vin" pin, that should work.
Thanks, I got my presence sensor set up using your video. You mentioned a PIR sensor in your next video. I do not see that video?
Glad it worked for you!
That is correct, it's still in the works :)
Hi, thank you for your video, very useful for newbie like me. Just a quick question, have you tested the HLK-LD2450 model, wonder how it performs, thanks!
I'm glad you found it helpful!
I have been testing the HLK-LD2450 for a while now, a video about it is also planned :)
@@SimplySmartHouse My esp32 board finally came home and I followed your tutorial. Pasted the code to yaml file and run install but then all my sensors are just Unknown. Do you have any ideas? Thanks!
Edited: Ok I think I figured it out, for some reasons mine doesn't work if I follow your tutorial step by step, I swapped the TX and RX pin on the LD2410C sensor (opposite to yours), and keep the same yaml config and it works. But if I re-edit the yaml to match with new swap RX and TX pins, it stops working again. I'm new to this so for now i'll keep it as how it works. If you know the explanation for my case please let me know, thanks again!
Hi, do you have any 2410 sensors working with the new settings, if yes, could you show me any of the settings you have working?
Yes i have a working setup, i'm working to release an updated video for the new LD2410 settings.
Thanks for the excellent DIY sensor. Working well if I turn off the fan.Any way we can improve this situation. Either by changing sensor or some settings
I'm glad to hear that the DIY sensor is working well for you! Yes, you can tweak the settings or add a motion sensor; that should do the trick.
Which settings works better in your experience?
@@kanalamrI prefer adding a motion sensor; then, you get the perfect sensor, in my opinion. However, if you only use the mmWave sensor, you can tweak the threshold of detection to try to avoid the fan triggering the sensor.
ESPHome documentation for the sensor LD2410 gives something different from the YAML mentioned in your video. I tried to use yours but failed, it seems to me that since they made this change in documentation the "old" YAML doesn't work with this sensor. What do you think? Thank you.
You are correct. Starting from ESPHome version 2023.8.1, there was a breaking change for the LD2410 component. I've just updated the blog post to accommodate this change.
Thanks a lot for sharing the info. I am planning to try this DIY project, but I',m a bit stuck with the ESP32. There should be with 30 or 38 pins? I've noticed that the one with 30 pins has 3v3 as output hence the one with 38 has 5v, as per your video. What would you recommend to buy?
You can go with either 30 or 38 pins, both will work just fine.
The 5v on the boards is sometimes called VIN.
Thanks a ton🎉
The only problem that I have with it is that there is a 1-2 second delay to turn on the light :( Not sure if it's a WiFi problem or what. I have switches over Zigbee (using HA).
That sounds like a WIFI problem, i have no latency at all.
Hi
I have made a project with microwave motion sensor to detect human movement behindwalls,working well,but could you please help me to find a way in order to measure movement distance from the wall
You can use the "moving_distance" entity, it should display the distance in cm of the detected moving target.
Could I combine this with a Panasonic pir on the same esp? As would then get the benefit of the speed of pir combined
Yes you definitely can combine those two sensors.
hi, i want to connect more about 10 ld2410 presence detectors, can i connect all sensors by wire on same GPIO... or i need separate GPIO for each sensor .. (any wifi version of this module not Bluetooth)
Hi! I'm uncertain about connecting 10 ld2410 sensors to one GPIO. It depends on the sensor's protocol. For definitive answer, check the HiLink documentation.
Hello! Thanks for the educational video. A question for you, dear author. Is it possible to configure the motion sensor in EspHome (ESP32, ESP32-C3) so that data is transmitted to the HomeAssistante server not via WiFi but via Bluetooth.
Those. do everything the same as in your lesson, but the channel for transmitting readings is Bluetooth
Such a sensor could operate on batteries for a long time.
great video, do you have a tutorial about this sensor using arduino?
Thanks, I haven't expanded into Arduino land yet :)
Hi! Is the new tutorial coming with pir sensor?
Took some time off, but more videos are coming up for sure :)
Where l2410 stands vs ld1115? Also lookong for next video with pir sensor as i have fan in every room
3:19 The LD1115H has no gates, making it less customizable than the LD2410, so it depends on the use case, In my experience, both sensors are quite reliable.
I believe the primary intended difference was the plug-and-play capability of using this sensor right out of the box. However, currently, that is not the case. 0:24
I’m working on the video, I have the same problem ;)
athom has a presence sensor with PIR
@denai9809 Thanks, already ordered one for testing ;)
I have been using the LD2410 for 2 months for a smart toilet in connection with a dimmer switch. Contactless switching on of the lights and adjusting the brightness according to the rising and setting of the sun. The distance parameter of the LD2410 is not reliable because it resets a long time after leaving the detection zone. I have the Motion energy parameter set to 40 to prevent false activations. The shutdown time is 15 seconds. A shorter time may cause the lights to turn off undesired.
Have you tried using the app with “engineering mode” to fine tune your sensitivity threshold per gate?
The application is used for the dedicated output on the LD2410. The parameters are monitored by the Home Assistant via the ESPHome module. I have automated the activation of the lights to the Still and Move Energy parameters.
Having trouble with the updated 2023.8.1 config from the blog post and a LD2410C using an ESP8266.
I can set parameters from HA, and see the changes happen in the HLKRadarTool bluetooth app. So I know HA is communicating with the LD2410C.
However all sensors show "unknown", also in the diagnostic section. Anyone seen this issue?
Which board are you using? Perhaps you could share your configuration, and I'll try to assist you.
@@SimplySmartHouse I've tried different boards. A ESP8266 Downloader, a D1 mini and a bare module, where the UART chip is on a backpack board, I can remove after the firmware is flashed ( so there is nothing else connected to RX/TX ).
I have double checked that RX->TX and TX-RX is connected as they should.
With it being a bare board, my configuration includes:
esp8266:
board: esp8285
framework:
version: recommended
logger:
baud_rate: 0
uart:
id: ld2410_uart
tx_pin: GPIO1
rx_pin: GPIO3
baud_rate: 256000
parity: NONE
stop_bits: 1
ld2410:
uart_id: ld2410_uart
I also tried to change the board to "esp12e".
Oddly, when I open the log over WiFi of the device, I do see the distance measurements being reported.
But the HA card still show the sensors state to be "Unavailable".
UPDATE: Got it to work. I had to delete the device info in HA, and recreate it.
where do i find the settings for LD2410B with a D1 Mini?
It should be mostly the same, just need to change the pins to your D1 mini, you can check this out: github.com/esphome/issues/issues/4356#issuecomment-1628257612
Wife approval is always the ultimate test! One question, does the sensor work through a door? Would be cool to add this behind a front door for presence detection
Totally :)
That’s a great idea, I guess it depends on the kind of door, the sensor can see through my wooden bathroom door and also through the wall,
It can’t see through metal though.
@@SimplySmartHouse Ahh that sounds promising, thanks for checking! Will pick one up to test out :)
Can I use the same code on a d1 mini?
You will need to change the 'tx_pin' and 'rx_pin' to fit your board
Can it sense behind wall?
Yes it can sense behind a drywall, tested it myself :)
Thanks for the video, have you also considered the LD2420 ?
I’m glad you found it helpful!
Yes, I’m actually testing the LD2420 so stay tuned :)
@@SimplySmartHouse hi pls 2420
Is there any way I can visually differentiate a LD2410 from a LD2410B ? thanks your time and attention!
I tried finding a visual difference, but they both look 100% identical to me
I had the same problem as you when only using Bluetooth. It was very unstable and that led me to your channel.
I followed your guide and when I try to install with the full yaml file (I copied and pasted directly from you) I get a error when flashing
Do you have tips on what I should do?
collect2: error: ld returned 1 exit status
*** [/data/office-presence-sensor/.pioenvs/office-presence-sensor/firmware.elf] Error 1
========================= [FAILED] Took 88.72 seconds =========================
BUT I can still see the LD2410 in Home Assistant and can add it as a device!!!
!!WOW!! Let see if it´s more reliable now then with only bluetooth
Yes, the bluetooth integration was really unstable when i tested it.
So did you got it working? if so what was the issue?
@@SimplySmartHouse Even though I got the errors, It still works. I have notice that it freezes and a reboot of HA is still needed. Just not as often as with bluetooth
@@SimplySmartHouse the ld2410b freezes once a day and I have to reboot HA. I have created a automation that reboots HA every day at 2 am
That’s very strange, if you want me to look at your configuration just send me a message on Facebook and I’ll take a closer look.
Other than that everything works as it should?
I'm using the 2410B and I get the error Communication with BH1750 failed! Using the VIN pin for 5v on a ESP WROOM-32.
Did you also added the BH1750 sensor?
I would try to add the ld2410b with the default settings from the esphome website.
@@SimplySmartHouse a lot of boards don't have a listed 5v out. Also I had my Rx and tx mixed up.
It also happened to me many times ;)
@@SimplySmartHouse how do you tune ld2410? I wish there was a better gui than just threshold values and sliders for g1-8. I'd like to increase the Presence sensitity/duration.
@@VoiceOverEngineer I used to it directly in the YAML, i totally agree.
And ld2420 and esp32 ?
Currently i'm working on ld2450, but ld2420 is also on my list.
been following but upon install all sensors shows unknown... can you suggest where went wrong?
Sure, usually it has to do with the wiring, can you share your board model?
@@SimplySmartHouse CH9102X I'm using
It seems to have the same pinout as I used, try to double check the wiring:
Vcc to 5v
Ground to ground
RX to P17(TX)
TX to P16(RX)
Then make sure to have the corresponding Esp32 code:
uart:
tx_pin: 17
rx_pin: 16
Let me know if that helps
@@SimplySmartHouse double checked everything, also restarted HA, still unknown showed
Got it, what sensor are you using?
You can try adding the code straight from the esphome website:
esphome.io/components/sensor/ld2410.html
I will double check my code later.
I am getting stuck here, any idea?[22:15:39][C][api:141]: Using noise encryption: YES
Can you provide more details? at what step exactly?
Thank you your relpy, i was able to get it working, please post more videos. thank you again@@SimplySmartHouse
Working on it :)
hiya, thanks for the video but just wondering if anyone has had any issue with the latest ESPhome update. it doesn't seems to be updating and kept getting errors on everything under ld2410.
ld2410: [source /config/esphome/esp32multisensors2.yaml:63]
-
The 'timeout' option has been moved to the 'timeout' number component.
timeout: 10s
The 'max_move_distance' option has been moved to the 'max_move_distance' number component.
max_move_distance: 6m
The 'max_still_distance' option has been moved to the 'max_still_distance' number component.
max_still_distance: 6m
etc...
Since the latest ESPHome update the ld2410 had breaking changes, I did add the correct YAML to the blog post, and I’m working on updating the video as well.
@@SimplySmartHouse yeah thanks. I saw that, I'm a bit confused with it. I also saw this on the esphome site. What I'm confusing about is the fact that it doesn't have the distance set anymore on the new syntax. So how will it know the sensitivity if we don't set them?
You can set the sensitivity dynamically through the integration. There's no need to upload new ESPHome code to adjust it. There's been a lot of confusion about this in the community, and I'll try to clarify it as soon as I can.
Great video but i keep getting the following error:
collect2: fatal error: ld terminated with signal 11 [Segmentation fault], core dumped

*** [.pioenvs/presence-sk/firmware.elf] Error 1
Could you please help???
Thanks, i have no clue about your error,
My only advice is to try it again from scratch, but i'm sure you already did :/
I am using Teyleten Robot D1 Mini ESP32 ESP-WROOM-32 WLAN WiFi+Bluetooth and connected it to RX and TX + power. Configured the TX/RX pins accordingly, but got a compile error.

Is this because I installed the esphome with bluetooth proxy? '
trying to move away from the bluetooth connection(NOT stable even when drawing power from the esp itself...).
I would try to install it again from scratch, it might have to do with your Bluetooth proxy installation.
Hi! I have a problem when trying to do the installation via Wi-Fi. It compiles without any issue, but when trying to do it via WiFi, it never connects. It keeps asking if it's connected to WiFi, etc. However, it was connected before, and it showed as online. I have tried setting a fixed IP, opening ports in my router, and setting a fixed IP in the router as well, but it never works. Can someone help me with this? With Bluetooth, I have no problems with the Bluetooth proxy; it doesn't give me any issues. The thing is, I have other boards that are Wi-Fi-only, and they don't work either. I don't see any proxy restrictions in my macOS network. Thanks.
I'm getting this message:
INFO Successfully compiled program.
INFO Resolving IP address of presence-despacho.local

From there, it goes offline, and it doesn't show as connected in the router. Thanks.
Hi, did you happen to change the name of your ESP device? @02:17
If so maybe try changing the hostname as shown at @02:29
Let me know if that helps.
@@SimplySmartHouse Hi! Thank you for responding. Indeed, I had already done everything you told me. I watched your video step by step, and it's well explained. In fact, I followed the video, but I don't know why my WiFi is giving me problems. I changed the name exactly as you did and was connected to WiFi with its IP on the router, but in the last step, it fails and disconnects, no longer appearing in the router.
Not sure how to help, I hope you could find a solution, maybe in the Home Assistant Community forum?
