# **Quick Start (Home Assistant)**

Follow the step-by-step guide to integrate your device with **Home Assistant**. [Set up your EPL device in Home Assistant](/doc/82661309-df52-470a-a668-7dbd15bcaaea)

# 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](/doc/515d8862-90dd-4d60-a5b9-af421e94cf22) .

### 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**](/doc/6640e98e-2d8f-4cbe-a705-5d215371b372) to visually create and manage zones, or see [How to Create Zones](/doc/5b75125c-e11e-4009-a366-59e9e9ff1a72) 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](https://www.printables.com/model/624830-everything-presence-lite-official-case).

## 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:

```javascript
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](https://play.google.com/store/apps/details?id=com.hlk.hlkradartool&hl=en_GB&pli=1) / [iOS](https://apps.apple.com/gb/app/hlkradartool/id1638651152)) 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.
