I thought it would be best to share our progress with the LD2450 here, as of right now, we’ve made about 500+ DIY sensors for the LD2450.
I don’t think this is a new thing, but still, we would like to have it here as a post to facilitate the exchange and discussion of this LD2450 radar module.
We have organized the documentation and information we have gathered at: Human Sensor 2A - Screek Workshop
Human Sensor 2A Zone Function Demo - YouTube
After getting a lot of feedback from users, we embarked on a lot of improvements to the original firmware, and now, judging by the feedback from the recent test firmware V230810_2_Beta, it’s working pretty well in general with the zone feature.
But there is still some room for improvement:For example, support for multiplayer mode in the official ld2450 firmware, and the demo mode, which we’ve heard from the hilink developers will be available this month. At least the multiplayer mode is already in their internal testing.
The display in HomeAssistant still doesn’t take full advantage of the intuitive function of coordinates, and we are still looking forward to working with you all to refine a lovelace display that shows a room area with a few dots moving around, which would be a lot cooler than the primitive ID display that shows a simple occupied state.
Likewise, the current setup area requires manual number entry, which isn’t intuitive enough, and would definitely be nice to have in some sort of drawing-like interface. We’re currently told that the folks at hilink are also envisioning a zoning feature from their app, presumably like the LD2410, which seems like a nice addition.
To give you a better experience of this groundbreaking cost-effective body tracking radar module, we’ve prepared more Sensor 2A to share with you, and in the meantime, we’re offering a 10% discount on all SCREEK sensors for the next 24 hours.

I’m looking forward to trying this out!

I have purchased 2, I have installed one in the kitchen to turn on the kitchen main light (zone 1), the sink light (zone 2), and the fires light (zone 3). Planning the second for the far side of the living room.
Seems to work reasonably well, need to optimize the timings and maybe put the sensor elsewhere (European kitchen, no central island big enough to dissect a dolphin) and need to light the main light better according to existing light level.
What is interesting is that the kitchen is open, and I could use a fourth zone to control the light in the living room just outside the kitchen area.
Maybe a template sensor to use the targets distance instead would be the solution, to check.
Thanks to this sensor I am finally starting to explore the real meaning of smart, autonomous home. Having HA control lights via tablet and buttons is fine but not really the idea of smart home and energy saving (i.e more comfort and sell wasted energy when the kids forget the lights on…).

After having countless issues with Aqara motion sensors in Smartthings I made the switch to Home assistant with a used thin client. I went on to purchase (5) esp32-c3s and (5) LD2450s thinking they were already supported by ESPHome. I have tried loading the 2A firmware onto my esp32-c3s since I saw images of the c3 being used in what I guess were earlier models of the 2A via ESPHome. However, I am not able to get the config to install on the c3s. Is there a barebones version of the config available for just the mmwave sensor without the light sensor? Or perhaps can someone point out what lines to remove to accomplish this? Is it possible to simply add the config to a esp32-c3 that is already connected to Home Assistant and local wifi without needing to install the screek firmware and connect to the AP created by the esp32? If this is not the correct place to ask could someone point me in the right direction? Any assistance is greatly appreciated.
Which pins on the ESP are you using for TX/RX?

I am at work away from the device but if I recall correctly it is RX GPIO05(I2C_SCL) and TX GPIO04(I2C_SDA).

Looks like they forgot to update the board in the YAML posted in the Github. It’s set to the the c3 mini.
I’m guessing you’d need to update the board:
esp32-c3-devkitm-1

I previously noticed that and updated the yaml with esp32-c3-devkitm-1 but the install failed. However, in hindsight I tried to install wirelessly instead of directly connected to thin client running HA and also may have tinkered with other settings as well. So, when I get home I will grab the yaml from the github again and only change the board to be sure.
This config is working for me:

# Set the device name

# Set the friendly name
friendly_name: 2A Sensor Test
# Provide the wifi SSID

The config you provided installs but in logs I am seeing NO OTA attempt made, restarting. Eventually it show, “There have been 10 suspected unsuccessful boot attempts.” “Boot loop detected. Proceeding to safe mode.” The esp32-c3 connects to my wifi and shows connected in ESPHome addon. However, there is no notification for new device detected and in Integration it doesn’t show up under Discovered. Should I be installing factory-human-sensor-2a-V230908_1_stable.bin or maybe the OTA firmware?
I’m not sure then. I just tested again using the YAML I posted above.
Created device in ESPhome.
Edited config and did a direct paste of the YAML above.
Selected install, manual, modern format.
Use ESPHome Web to flash.
The board reset, connected to wifi, and showed up in device discovery. Added it and can see all the sensor data.

Zones? From one sensor? Where is this documented?

here:
and here:
After a very long testing period, and also with the feedback and support from the first users, we had the opportunity to refine it to a much better height, and this is the current 2A, where we support 3 zone settings on the firmware, as well as an...
Zone Support : Based on the current firmware, three recognized zones (Zone1, Zone2, Zone3) are supported, as well as one excluded zone (Zout1), which can be switched on and off individually. Enabling the exclusion zone will disregard excluded targets in all recognition judgments.
Target Coordinate detection : Compared to LD2410, now you can support X coordinate reading! And Y coordinates are more accurate! They are accurate up to 36cm.
One reason why the LD2450 with this Firmware is such an Awesome sensor!

Hi, we haven’t received any such bug feedback yet, so our initial guess is that there may be some setup hurdles.
A general and unexpected understanding might be that x-begin and x-end are reversed, i.e. in the case of a negative number, it might be that the former has a bigger number.

This is a feature of the ld2450, a new sensor that was discussed more extensively in our other thread and is now supported by more open source libraries.
