Presence sensor LD2410 missing some sensore values

nessumsaR · August 16, 2023, 10:23pm

Hi,
I’m wondering why ESPhome is creating extra data points for my LD2410 pressens sensor, the sensor data that is add in the dash board does not yeld any data.
I did see this as an error and have tried to debug it.

The extra sensor data point (the one that are not showing data) are not defined in the YAML or the libery ld2410_uart.h.

I’m new to this ESPhome but have tried to debug/understand the logic on the sensore data that are shown in the dash boad after adding it.

Set up:
ESP8266 conected to the LD2410 (Rx Tx +5v,G)
d1_mini
by Espressif
Firmware: 2023.7.1 (Aug 16 2023, 00:18:23)

Code/configuration:
Im using this GitHub - rainchi/ESPHome-LD2410: ESPHome LD2410 mmWave Radar Sensor Custom Component
YAML configuration and ld2410_uart.h code, changed uart1 to uart_1 there was not alowed to be used.

I dod get sensore data but not all som are missing data-

Sensor data that works and gives data all are defined in the yaml:

Detect Distance
Has Moving Target
Has Still Target
Has Target
Last Command Success
Moving Target Distance
Moving Target Energy
Still Target Distance
Still Target Energ

No sensor data! and not in the yaml or the ld2410_uart.h code-?

Moving Target
Still Target
Detection Distance
Move Energy
Moving Distance
Still Distance
Still Energy

Is this just a normal behaviure of the ESPhome, that it creates new sensore data for the dashboard, and I shoud just remove the sensore data that does not yeld any data from the dasboard?
I like to know if im missing some sensor data from the LD2410
I looked at the custom logic handlePeriodicData function in the ld2410_uart.h code maybe there is some off the data thet is not being processed corectly… it is bit advanced for me to debug the c++

Yes. Just don’t show those values.

Any issues with this custom component, you will need to ask the component author, not the ESPHome team

I would probably move away from using a custom component for the LD2410 in ESPHome since it is now directly supported and is about to be updated shortly to enable the LD2410 to be configured directly in HA and not just via the YAML or the HLKRadar app.

Add configuration flow abilites to the ld2410 component

# What does this implement/fix? Currently, in order to easily calibrate we ne…ed to download the radar app and do it over Bluetooth. To support the calibration process you can now: 1. enable engineering mode 1. monitor the gates values 1. change the gates thresholds and repeat step 2 if necessary (without reflashing esp) 1. disable engineering mode In the updated docs I added a suggestion of a custom HA card that will make this process super easy, same as the app :-) ## Types of changes - [ ] Bugfix (non-breaking change which fixes an issue) - [x] New feature (non-breaking change which adds functionality) - [x] Breaking change (fix or feature that would cause existing functionality to not work as expected) - [ ] Other **Related issue or feature (if applicable):** fixes <link to issue> https://github.com/esphome/feature-requests/issues/2107 **Pull request in [esphome-docs](https://github.com/esphome/esphome-docs) with documentation (if applicable):** https://github.com/esphome/esphome-docs/pull/2680 https://deploy-preview-2680--esphome.netlify.app/components/sensor/ld2410 ## Test Environment - [x] ESP32 - [ ] ESP32 IDF - [ ] ESP8266 - [ ] RP2040 ## Example entry for `config.yaml`: (must be on latest dev branch) ```yaml external_components: source: github://regevbr/esphome@ld2410 components: [ld2410] api: services: - service: set_ld2410_bluetooth_password variables: password: string then: - bluetooth_password.set: id: ld2410_comp password: !lambda 'return password;' uart: id: ld2410_uart tx_pin: GPIO17 // Your pin rx_pin: GPIO16 // Your pin baud_rate: 256000 parity: NONE stop_bits: 1 ld2410: uart_id: ld2410_uart throttle: 1500ms id: ld2410_comp select: - platform: ld2410 distance_resolution: name: distance resolution baud_rate: name: baud rate light_function: name: light function out_pin_level: name: out pin level button: - platform: ld2410 factory_reset: name: "factory reset" restart: name: "restart" query_params: name: query params number: - platform: ld2410 timeout: name: timeout max_move_distance_gate: name: max move distance gate max_still_distance_gate: name: max still distance gate g0: move_threshold: name: g0 move threshold still_threshold: name: g0 still threshold g1: move_threshold: name: g1 move threshold still_threshold: name: g1 still threshold g2: move_threshold: name: g2 move threshold still_threshold: name: g2 still threshold g3: move_threshold: name: g3 move threshold still_threshold: name: g3 still threshold g4: move_threshold: name: g4 move threshold still_threshold: name: g4 still threshold g5: move_threshold: name: g5 move threshold still_threshold: name: g5 still threshold g6: move_threshold: name: g6 move threshold still_threshold: name: g6 still threshold g7: move_threshold: name: g7 move threshold still_threshold: name: g7 still threshold g8: move_threshold: name: g8 move threshold still_threshold: name: g8 still threshold light_threshold: name: light threshold text_sensor: - platform: ld2410 version: name: "presenece sensor version" mac_address: name: "presenece sensor mac address" switch: - platform: ld2410 engineering_mode: name: "engineering mode" bluetooth: name: control Bluetooth binary_sensor: - platform: ld2410 has_target: name: "presence" has_moving_target: name: "movement" has_still_target: name: "still" out_pin_presence_status: name: out pin presence status - platform: gpio pin: GPIO13 // Your pin name: gpio out pin presence device_class: presence sensor: - platform: ld2410 moving_distance: name: "Moving distance (cm)" still_distance: name: "Still Distance (cm)" moving_energy: name: "Move Energy (%)" still_energy: name: "Still Energy (%)" detection_distance: name: "Distance Detection (cm)" g0: move_energy: name: g0 move energy still_energy: name: g0 still energy g1: move_energy: name: g1 move energy still_energy: name: g1 still energy g2: move_energy: name: g2 move energy still_energy: name: g2 still energy g3: move_energy: name: g3 move energy still_energy: name: g3 still energy g4: move_energy: name: g4 move energy still_energy: name: g4 still energy g5: move_energy: name: g5 move energy still_energy: name: g5 still energy g6: move_energy: name: g6 move energy still_energy: name: g6 still energy g7: move_energy: name: g7 move energy still_energy: name: g7 still energy g8: move_energy: name: g8 move energy still_energy: name: g8 still energy light: name: light ``` ## Checklist: - [x] The code change is tested and works locally. - [x] Tests have been added to verify that the new code works (under `tests/` folder).

Ok thankyou, I have learnd sevral things trying to debug and get the ld2410 to work with the custome componet, you are probaly rigth that I should move to the HA when the settings are implemented.

I removed the extra stuff the the HA/ESPhome add (i dont need to undestandt the inner workings of that rigth now ), and the sensor is working switching on and off the ligth in my EE lab.

And the timing couldn’t be any better, the above update to the LD2410 component in ESPHome has just been released as part of ESPHome 2023.8.0
The ESPHome documentation page above for the LD2410 component has also been updated with the details for the YAML config.

Has anyone have a full esphome working code with the new configuration for LD2410.

My previous installation was working with the following code in my esphome unit.

binary_sensor:
  - platform: gpio        # LD2410
    pin:
      number: ${LD2410_pin}
      mode:
        input: true
        pullup: true
    name: ${esp_id}_Presence
    device_class: presence

I try multiple options without success.
Do I have to include Binary Sensor, Sensor, Switch, Number, Button, Text Sensor, Select etc code to only get a presence and movement?

athua · August 20, 2023, 3:06am

See the following thread as there are examples of the YAML code that has been used that works:

Have you also wired up the TX and RX pins as I think the updated LD2410 ESPHome component is designed to work with the TX/RX pins so that you can fully configure it directly from HA.

Looking at the documentation, the OUTPUT pin configuration has changed to the following:

binary_sensor:
  - platform: gpio
    pin: REPLACEME
    name: gpio out pin presence
    device_class: presence
