What you described is really great, can you quote you to those who buy our diy radar? We will sign your name, and as a gift if you would like, we would like to give you 1 small radars (esp32-s2+ld2410c) of our design, you may need to send us privately an address that can be mailed internationally.
I’m not sure if this post is allowed here 
Yes, I’m happy for you to use my description for tweaking the sensitivity.
Hello, Martin. This is Stella from HiLink. Thank you very much for using our products. I’ve consulted our engineers and the answer is as follows: When a person is at rest, the module detects the rise and fall of the chest cavity to determine if there is still a person present. Firstly, whether the installation position does not detect the chest rise and fall. Secondly, the stationary energy value can be adjusted downwards.
I hope the above answer is helpful to you. If you have any questions during the use, please feel free to contact me.

Hello, Martin. This is Stella from HiLink. Thank you very much for using our products. I have consulted our engineers and the answer is as follows: The Bluetooth module that comes with the 2410C is used to set up the module parameters and configurations, there is no data transmission function, if you want to connect via Bluetooth, you can add a Bluetooth module.
I hope the above answer is helpful to you. If you have any questions during the use, please feel free to contact me.

Hi all,
I have tried to follow the instruction reported here and I believe to have succefully create my first presence detector.
Yesterday everything seems to work well but this morning I found the Esp32 S2 mini off line.
The funny thing is that the sensor seem still connected and working
How is possible?

The ESPhome dashboard uses mDNS to find the device unless you specify use_address in the WiFi config.
The ESPhome integration uses the IP address to communicate with the device.
So, likely just an mDNS issue causing it to show offline in the ESPHome dashboard.
What do you suggest to do? Repeat the Install procedure via USB?
I want to say that if you edit the config for it in the dashboard, add the “use_address” option, and save, the dashboard will immediately start using the IP instead of mDNS. So just changing the config may resolve it.
With that said. It looks like you might have the older config. So refreshing via USB may be the better route. You can try out my config that’s updated to use the ESPhome components for the LD2410C.

I have used pins 16 and 17 for rx/tx so I should change the following section of the yaml, correct?
uart:
tx_pin: GPIO18
rx_pin: GPIO33
baud_rate: 256000
parity: NONE
stop_bits: 1
I suppose I should also add the api key, correct?
Yes to changing the pins. The API key is only necessary if you feel so.
It works very well - thanks!.
There are still some entities not available but it should not be a problem.
Looking the log file I saw few warning messages
[14:23:22][W][component:214]: Component ld2410 took a long time for an operation (0.16 s).
[14:23:22][W][component:215]: Components should block for at most 20-30ms.
[14:23:23][D][binary_sensor:036]: 'Moving Target': Sending state OFF
[14:23:23][D][binary_sensor:036]: 'Still Target': Sending state ON
Regarding the Automation do you have a good proposal to use all the potentiality of LD2410C?
thanks again
do you have STL or thinkcad files for this case?
Hi! Can you share your yaml file ?
sure.

That looks fine to me. ESPhome tries to programmatically restart the esp board but that doesn’t work with the S2. You have to unplug/plug in or hit the reset button on the board.
Can someone provide code to turn off the blue flashing led???
For the current screek firmware uses an indicator light to indicate the networking status, which is automatically turned off once networking is complete.
