LD2410 esphome tips

liminal · August 19, 2023, 8:00am

Just some info that could help someone. I found that my ESP32s would enter a boot loop if I had MQTT info in the YAML.

This was more for my DF robot sensors, but if you are using MQTT you could have the same issue.

Also what’s the new values for;

Thanks

ld2410: [source /config/esphome/bedroom-presence.yaml:46]
  - 
    The 'timeout' option has been moved to the 'timeout' number component.

I think this is MQTT, I removed my MQTT login details and it stopped the boot loop

When changing the thresholds, where do the values go in the yaml? This gives an error:

    g0:
      move_threshold: 50
        name: kitchen radar g0 move threshold
      still_threshold: 50
        name: kitchen radar g0 still threshold

I built the custom card. When I turn engineering mode on with the switch, it turns off again in a few seconds. Is this normal?
Thanks

Yeah it really does not explain the new config well at all

liminal · August 20, 2023, 1:49am

Ok, I got it.

Here is the config, it actually allows you to adjust the gates from within HA now, which is cool.

I also added the diagnostic sensors for the gates, but they don’t seem to work? Anyone else having that?

would pay to go back and review THIS PAGE as the sensor config has changed a lot if ya werent you beta version … also has a very handy card layout for testing & config

liminal · August 20, 2023, 2:23am

I think all that’s changed, you don’t need the card, you can do it all from the device page?

So you can configure the gate thresholds

And I’m assuming it will give you the actual energy output of the gates so you can dial it in. But as you can see, mine picks up nothing. Wanted to see if this was working for others and just a me thing or not.

Enable engineering mode

Gaston · August 20, 2023, 4:42pm

Wow, this solve my problem. I think that example code should be included in the ESPHome documentation.
Question: What is the “Light Function” and how can it be used?
What is “out pin” and how to use it?

jcd420 · August 20, 2023, 7:07pm

I had same issue. I resolved by enable engineering mode directly on ld2410 by Bluetooth

sebcaps · August 20, 2023, 7:21pm

As per doc :

light (Optional, int): When in engineering mode, indicates the light sensitivity, otherwise unknown. Value between 0 and 255 inclusive. Though it seems that the value 85 is the lowest value at complete darkness. All options from Sensor.

I assume the config of the component is not quite easy and a lot items to handle and new version comes with breaking change, but everything is written in doc.

Without any offense, but from what I can read in this thread, many questions could be avoided with a carefull reading of the doc. And not only copying the parameters from other with others needs and requirements.

Gaston · August 20, 2023, 10:14pm

I think that I figure it out. The LD2410 has a LDR (Light Dependant Resistor). The “Light Function” is use with the “Light Threshold” to control the activation of the LD241 ON/OFF based on Above/Below Threshold.

liminal · August 20, 2023, 11:43pm

I don’t disagree, but for those of us still getting into this. We don’t really know what we are looking at or what is pertinent half the time. So while you are right, it really helps us newbies when we get whole configs to give context.

As an example, I still dont know what that light thing is for and I did read that part of the doc.

Is it saying there is a lux sensor? Ive never seen that mentioned.

athua · August 21, 2023, 12:50am

Yes, there is a lux sensor on the LD2410. I don’t believe it is very sensitive but there is one and it currently only works if you have Engineering mode enabled.

nickrout · August 21, 2023, 2:27am

Well why don’t you add it then. That is how the docs get improved.

RaptorHunter · August 21, 2023, 3:14am

I can’t get the ld2410_id to change entity names.

liminal · August 21, 2023, 4:06am

Cool thanks for that. I guess that’s why it wasn’t advertised as a feature.

switch:
  - platform: ld2410
    engineering_mode:
      name: "engineering mode"
    bluetooth:
      name: "control bluetooth"

Added these and got the diagnostics working.

But I dont really understand how to dial it in. Anything more then 2m does not show up even after changing the detection distance to 7 (is that meters?)

Do I up that value on the gates, does that increase the radar’s power?

athua · August 21, 2023, 4:33am

The higher the value for the gates, the more movement is required to trigger detection.
So as a start, reduce them to something low like 10 and have engineering mode turned on and watch the move and still energy values for each gate when there is no one present in the room and adjust the gate threshold to above those values to stop false detections.

liminal · August 21, 2023, 4:37am

Thank you!

Thats awesome, I assumed it went the other way.

Ill start testing it

EDIT

I also found this, can someone confirm these are the distances for the gates? Ignore the power values, I’m just talking about the gate and corresponding distance values.
