FAQs

Motion Detection

Will Everything Presence Lite detect moving animals or objects?

Yes. The sensor detects any moving object, including pets, fans, and even minor movements like shifting blinds.

My sensor is giving false detections. What should I do?

In most cases, the sensor is accurately detecting small movements that may not be immediately visible. To fine-tune its sensitivity, refer to the How to Tune Your EPL Sensor .

Can the sensor detect motion direction or specific zones?

Yes! Everything Presence Lite supports up to 4 configurable zones, allowing you to define specific areas within the sensor's field of view.

Use the Zone Configurator to visually create and manage zones, or see How to Create Zones for manual setup.

The sensor does not track motion direction, but it can detect which zone a target is currently in.

Customization

Can I 3D print my own case?

Yes. You can download the official case files from Printables.

Home Assistant Integration

My Home Assistant database is growing too fast after installing Everything Presence Lite. How can I reduce its size?

Certain sensor entities update frequently, especially in high-activity areas. These include:

  • target_#_active

  • target_#_angle

  • target_#_distance

  • target_#_resolution

  • target_#_speed

  • target_#_x

  • target_#_y

To prevent excessive database growth, you can:

  • Disable these entities if they are not needed for automations (note: this disables the Zone Configurator).

  • Exclude these entities from Home Assistant's database recorder while keeping them available for real-time monitoring and automations.

To exclude them, add the following to your configuration.yaml file:

recorder:
  exclude:
    entity_globs:
      - sensor.everything_presence_lite*target*

Troubleshooting

My EPL stops updating occupancy after some time, but light levels still update.

This issue is caused by a firmware bug in early versions of the LD2450 mmWave sensor. Updating the firmware should resolve the problem.

Update the LD2450 firmware:

  1. In Home Assistant, enable the mmWave Bluetooth entity if it is disabled.

  2. Install the HLKRadarTool app (Android / iOS) and stand near the EPL.

  3. Connect to the LD2450 sensor and update the firmware to version 2.04.23101915 or later.

    • If the HLKRadarTool app crashes on iOS, use RadarTools instead.

  4. After the update, toggle the mmWave Bluetooth entity off in Home Assistant to prevent unauthorized access. You can disable it entirely if it is no longer needed.
