my yaml also includes a ledstrip, so you can ignore that part if you don’t need it (basically what @Holdestmade posted)

Dont know why, but new config broke my sensor completely.

  1. It stops reporting any data
  2. When I try to access device through web interface it resets it.
  3. When I try to flash updated firmware it resets it and it stops connecting to wifi, just blinks status led

Can you try removing the following from your YAML:

  source: github://regevbr/esphome@ld2410
  components: [ld2410]
402

Hello, is there any side effects to leave engineering mode on for extended periods in ESPHome?

I’m thinking of charting the energy of all gates and doing some funky processing on the data over a month.

403

Just a short how did you get this software in an english version, all I see and can find is the Chinese which is gibberish to me.

404

i have the same problem with the last update of LD2410 and Esphome, there is always 3-4% still energy and my sensor is always in “detect” mode…

I try your settings, its better but still the same problem, the “still energy” take a while to enventually go to 0%, what make the “detect” state false.

Is someone has experiment a similar behaviour please?

EDIT : noob am i…just set the timeout to 10s and work great lol

405

Tried, same, not working.

[13:12:21][W][ota:102]: Last Boot was an unhandled reset, will proceed to safe mode in 7 restarts
406

Hoping there comes a new video soon on youtube that explains what just happen and what these new setting do

407

Older versions defaulted to Chinese if the phone language was not English.
The very most recent one fixed that in the sense that the app defaults to English, now.

408

esp8266 d1mini. all parameters are not available!

409

Updated to esp 2023.8.0? Have you read the changelog?

410

2023.8.1
what is in there? It does not say that device will be highly unstable rebooting at every opportunity.

411

I think this component made esp32 unusuable.
receiving this error:

updated my two sensors.
the one in the kitchen works like it always have worked.

no matter what i do, i can not get the livingroom sensor to work.
when i press the (soft) restart button i get the following.

image785×126 30.6 KB

and then nothing really is changed.
i think i swap out the LD2410 sensor for a new one and see what will change.

edit
oke, so i disconected the LD2410 sensor from the board.
let the board boot without the LD2410 sensor.
disconnected the board from power, and connected the LD2410 sensor.
restarted the board by connecting the power.
and there it goes, works like a charme.

next question, what does control bluetooth does?

and what does engineering mode does?

Control Bluetooth: Toggles the Bluetooth Power on LD2410B. If off, you can’t configure it using the app.

Engineering Mode: Turns on tracking of each gate energy, and allows changing of threshold values. Basically facilitates all you need to calibrate the device to its environment.

Question adding on to engineering mode, are there any cons to leaving engineering mode on all the time?

Tried without success, can’t access to the ESP ip.

Ping works, but it’s not starting

don’t know if this has any sense

EDIT:

As stated in github, removed webserver and now esp boots fine.

let’s check if it works fine

I wonder about the volume of sensor updates that engineering mode creates, since it seems like leaving it on all the time might cause a lot of unnecessary writing to the logbook. I can’t quantify the performance impact of that, but my gut instinct is that it’s better to turn it off when not actively tuning the sensor.

417

Is it possible just to hardcode the gate values like before (see below)? I didn’t solder a wire on the out pin and I assume that’s required for the engineering mode to work correctly?

g0_move_threshold: 40
g0_still_threshold: 41

418

I don’t believe that the out pin is required unless you want to use it the way you would a single-wire PIR. Engineering mode should still allow you to tune the values that trigger the presence, has_moving_target, and has_still_target binary sensors, which come in over the UART pins.
