HLK-LD2410S Low energy 24GHz mmWave presence sensor~

This feature is not included in precompiled binaries

When compiling your build add the following to user_config_override.h:

#ifndef USE_LD2410S
#define USE_LD2410S
#endif

This feature is designed only to work with HLK-LD 2410S module. To work with the HLK-LD2410(B,C) modules see here.

Configuration~

Wiring~

HLK-LD2410S-wiring

HLK-LD2410S	ESP
GND	GND
3V3	3.3V
OT1	GPIOx
RX	GPIOy
OT2	GPIOz

Warning: The power supply voltage of the module is 3.3V

Tasmota Settings~

In the Configuration -> Configure Module page assign:

GPIOx to LD2410S Rx
GPIOy to LD2410S Tx
GPIOz to Switch or Button

Settings example

Usage~

Tasmola is ready to read the status packet from the LD2410S module

Console output:

15:46:09.267 RSL: SENSOR = {"Time":"2024-11-09T15:46:09","LD2410S":{"Distance":196.0, "People":2}}

Where People values: 0/1 - not detected, 2/3 - detected

Commands~

Reread common, trigger and hold parameters from device (use this command after change module settings or after LD2410S_AutoUpdate command):
```
LD2410S_ReRead
```

Show previously received parameters on startup or after LD2410S_ReRead command:

LD2410S_Parameters

and result:

15:55:56.399 RSL: RESULT = {"LD2410S_Common":{"Near Door": 0,"Far Door":16,"Hold Time":10,"Status freq":10,"Distance freq":10,"Response speed":5},"Trigger values":[47,46,37,35,31,30,31,32,31,30,29,31,30,29,27,29],"Hold values":[45,45,34,32,30,29,30,31,30,29,28,30,29,28,26,28]}

Set common parameters: near door, far door, hold_time, status_freq, distance_freq, response_speed (see manual):
```
LD2410S_SetCommon 0-16,1-16,10-120,5-80,5-80,5/10
```
Set trigger values (the value at which the status changes to "people"):
```
LD2410S_SetTrigger n,n1..n16
```
Set hold values (the value of holding the "people" status):
```
LD2410S_SetHold n,n1..n16
```

Set device output mode 0-short, 1-normal:

LD2410S_Out_Mode 0/1

Console output in short mode:

16:09:49.247 RSL: SENSOR = {"Time":"2024-11-09T16:09:49","LD2410S":{"Distance":0.0, "People":0}}

Console output in normal mode:

16:22:59.255 RSL: SENSOR = {"Time":"2024-11-09T16:22:59","LD2410S":{"Distance":187.0, "People":2, "Energy":[0,0,209,217,86,131,104,141,80,128,116,253,251,209,51,232]}}

Start autoupdate trigger and hold thresholds/ Params: trigger_scale,retension_factor,scan_time:

LD2410S_AutoUpdate 2,1,60

Concole output:

16:29:58.239 RSL: SENSOR = {"Time":"2024-11-09T16:29:58","LD2410S":{"Update threshold":"0%"}}
16:29:59.261 RSL: SENSOR = {"Time":"2024-11-09T16:29:59","LD2410S":{"Update threshold":"2%"}}
16:30:00.277 RSL: SENSOR = {"Time":"2024-11-09T16:30:00","LD2410S":{"Update threshold":"3%"}}
...
16:31:01.230 RSL: SENSOR = {"Time":"2024-11-09T16:31:01","LD2410S":{"Update threshold":"100%"}}

And in main web page:

Start reports every seconds (need for tuning in normal output mode):
```
LD2410S_Follow 0/1
```

Rules~

You can use the LD2410S trigger to create rules, example:

rule1 ON LD2410S#Distance >0 DO state ENDON
rule2 ON LD2410S#People =2 DO state ENDON
