This ESPHome code should add the timeout config for Any Presence:

number:
  - platform: template
    name: "Any Presence Timeout"
    id: any_presence_timeout
    min_value: 0
    max_value: 600
    mode: box
    device_class: duration
    entity_category: config
    unit_of_measurement: s
    icon: mdi:timer-off
    step: 1
    optimistic: True
    initial_value: 0
    restore_value: True

binary_sensor:
  - platform: template
    name: "Any Presence"
    id: any_target_exsits
    device_class: occupancy
    filters:
      - delayed_off: !lambda |-
          return id(any_presence_timeout).state * 1000.0;

We synchronized athua’s code into it, and now a public firmware update can get this functionality.

A bit of a shame: the name of this property is too long, making it obscured in the HA properties.

I’ve updated my 2A with V230905_1_BETA and tested it by setting a 60 second timeout for ‘Any Presence’ and it clears 60 seconds after I left the room.

Hello,
i have tried this yaml file screek human sensor stable with a luatos board - official page, but i only get a boot loop.
I have also specified the platformio options:

  platformio_options:
    board_build.f_flash: 40000000L
    board_build.flash_mode: dio
    board_build.flash_size: 4MB

esp32:
  board: esp32-c3-devkitm-1

I have tried with a “regular” yaml file and the board works as expected.

My logs are like this:

ESP-ROM:esp32c3-api1-20210207

I have also tried the beta binary file, didn’t helped.
Thanks!

Thanks! Getting presence logs in minutes now rather than every few seconds.
Still working on fixing to the best position in the room, might need to print one of those motion sensor mount for the corners and tilting it.

Although Zone1 targets does not change, the Zone1 presence briefly changes to OFF and then to ON again in the same second. This occurs occasionally.

The “All presence” sensors stays still ON during Zone1 is shortly OFF.

Zone1 settings:

Zone1 Timeout	  60 s
Zone1 X-Begin	-600 mm	
Zone1 X-End      600 mm	
Zone1 Y-Begin    400 mm	
Zone1 Y-End	    1600 mm

What could be the reason for this beahivoir?

If you’re using the same c3 development board that we are, you may run into some more troublesome areas.
One of them is that we use a GPIO11, this cannot be used without unlocking it, and will cause the I2C to lock up and then restart repeatedly.

From your logs, it looks like the serial port logs are gone as well.

If you want to DIY a 2A radar, I’d suggest starting with a device you’re familiar with and modifying the GPIOs in the code. e.g. ESP32 development board.

Using a C3 without a USB serial port requires some special skills, some kernel tweaks to make the USB serial port stably supported, and some modifications to the esp32 built-in libraries in order to unlock the motherboard’s led lights.
All of this makes, things a bit more complicated.

From the logs, the behavior does seem strange. But the logs are a bit too short, so if possible, please post some nearby logs that might be better to investigate.
One of the things I might also be puzzled by is that Target 1 X, seems to have become Zone1 X here.

Since it’s 1am and I can’t access the code right now, this may be some name bug on my part that I’ll need to investigate further tomorrow.
But as it stands, we need a log with a little more detail.

[18:01:36][D][sensor:094]: ‘Zone1 X’: sending state -142.00000 mm with 0 decimals of accuracy
[18:01:36][D][sensor:094]: ‘Zone1 Y’: Sending state 1138.00000 mm with 0 decimals of accuracy

Thx for you fast answer.

I build a DIY LD2450 sensor with an M5 Stack Atom Lite based on V230905_1_BETA.

Only removed the illuminance and CPU part from your code.

The part that is not understandable:
20:52:24][D][sensor:094]: Zone1 Target Counts: Sending state 0.00000 targets with 0 decimals of accuracy

[20:52:35][D][sensor:094]: Zone1 Target Counts: Sending state 1.00000 targets with 0 decimals of accuracy

…and after 60 seconds (Zone1 timeout):
[20:53:24][D][binary_sensor:036]: Zone1 Presence: Sending state OFF
[20:53:25][D][binary_sensor:036]: Zone1 Presence: Sending state ON

If I understood the handling correct, 20:52:35 Zone1 Target Counts: Sending state 1 should cancel the switch off at 20:53:24 Zone1 Presence: Sending state OFF (due to delayed_off “zone1_x_timeout”).

From the very detailed information you’ve given, it does seem that there is a logical shortcoming here: it looks like the way athua’s delay closes, it can’t be interrupted in the middle of the process, which would be a problem.
We may need to rewrite a function for it to manage and clean up this timer.

This is an important discovery, and it means a small bug exists.

screek-workshop · September 6, 2023, 4:00am

According to the documentation there is no error

(Required, time, templatable): When a signal OFF is received, wait for the specified time period until publishing an OFF state. If an ON value is received while waiting, the OFF action is discarded. while waiting, the OFF action is discarded. Or in other words: Only send an OFF value if the binary sensor has stayed OFF for at least the specified time period. When using a lambda call, you should return the delay value in milliseconds. Useful for debouncing push buttons.

The problem is that while waiting for the state, our push code won’t push the new state (because the compared state value is still ON and won’t break the time interrupt), which results in a canceled state that won’t be broken.
So this problem will be a bit more complicated.

athua · September 6, 2023, 5:19am

I have had a look at the code and the following change seems to help. It may need some further testing to see if it does fix the issue, ie. move the push for the target exists when the target count changes rather than when the target presence changes:

          if (id(zone1_target_count).state != target_count_in_zone1){
            id(zone1_target_count).publish_state(target_count_in_zone1);
            id(zone1_target_exsits).publish_state(has_target_in_zone1);
          }
          //if (id(zone1_target_exsits).state != has_target_in_zone1 ){
          //  id(zone1_target_exsits).publish_state(has_target_in_zone1);
          //}

Very genius approach! I think it will work very well and we will integrate this patch.

haip · September 6, 2023, 8:09am

Added your fix (for all 3 zones) for testing. Will give feedback. Thx for the quick solution.

screek-workshop · September 6, 2023, 9:41am

By starting with a concern about the unsatisfactory static capability of the 2A radar, we found time today to do a basic test using three radar modules:

HLK-LD1125F: It’s an alternative version of the LD1125H, which seems to have lower power consumption and greater range. We tested the CEM5825F at the same time and they have almost identical performance and hardware, as does the OP.
HLK-LD2410B: This is the radar used on top of the 1U, 1W, very well known and very cost effective.
HLK-LD2450: This is the radar used on top of the 2A, with three target tracking capabilities, but HLK only has one open at the moment.

After a brief test, we came up with some of these conclusions:

The micro-motion detection ability of the LD2450 is in fact quite good, not too much worse than the 2410 or 1125F, as long as there is a little bit of activity, the target will not disappear. Conversely, when there is very little movement, it will remain undetected on the 1125F for a while and then become unoccupied (utilizing the delay setting). With athua’s recent code contribution, the delay off added to 2A could better ameliorate this unoccupied state issue. The latest release, V230906_1_beta, further improves a shutdown logic that, in conjunction with the shutdown delay, allows for more reliable micromotion detection.
The LD2410 has great short range detection capability, but the displayed distance can be extremely off, making it difficult to adjust the parameters.
For fixed interference capability, the LD1125F is as bad as the LD2410B and requires adjusting the parameters to exclude it, while the LD1125F can only be adjusted for three levels of sensitivity.
The LD1125 has a very large detection angle and high sensitivity, and the distance also seems to be farther. But it was limited by being a desktop computer and couldn’t be moved to a larger living room to test it.
The 2A’s LD2450 looks like a great radar as a single mode, and has its own advantages over anti-jamming. While the LD2410 has an advantage in cost/performance ratio with a comprehensive setup, the LD1125F is simple to setup and has a very strong micro-motion detection capability with a greater range and angle.

Next, we hope to build a radar based on the LD1125F, our codename might be Human Sensor F25.

Here’s a video recorded during testing:

screek-workshop · September 6, 2023, 9:49am

public version update to v230906_1 now

haip · September 6, 2023, 7:24pm

Tested it and it works as expected. One very small thing after ESP restart, the presence sensor for the zones stays at “unoccupied” (count is 1) if you are in front of the sensor. Move out and in the zone triggers the presence sensor fine.

If I add this code back in addition, it works correctly even after an ESP restart:

          if (id(zone1_target_exsits).state != has_target_in_zone1 ){
            id(zone1_target_exsits).publish_state(has_target_in_zone1);
          }

screek-workshop · September 6, 2023, 10:36pm

This patch looks to add a layer of ensuring updates are in there, which is interesting. We’ll add it for testing as well.

If possible can the post startup logs replicate some of this and we can investigate together what this might be causing?

Gasinskiy · September 8, 2023, 12:17am

Thanks for a great job! Please advise, I slightly adjusted the source code for Wemos D1 Mini based on ESP8266) I hoped it would work. But unfortunately, there are zeros in the indicators, but in the logs:
02:50:01 [W] [component:204] Component uart took a long time for an operation (0.09 s).
02:50:01 [W] [component:205] Components should block for at most 20-30ms.

I still have Wemos based on ESP-WROOM-32 and ESP32-S2F, maybe they will fit, or the minimum supported board should be based on ESP32-С3? Thanks!

athua · September 8, 2023, 2:28am

I have my LD2450 connected via GPIO17 for TX and GPIO16 for RX on a Wemos Compatible D1 Mini ESP32 which is based on the ESP-WROOM-32 chip with no problems.
