# HAP (Apple HomeKit)

{% hint style="info" %}
This skill is outdated and will no longer be further developed! Instead, we recommend [Matter](/nomos-system/integrator-en/skills/matter.md) as a new forward-looking standard.

The HAP Integration (HomeKit Accessory Protocol) allows you to connect the **nomos system Controller** to **Apple HomeKit**. This is done easily by scanning a QR code with your iPhone or iPad.

**Steps to Set Up:**

1. **Activate HAP:**
   * Make sure the switch is turned **ON** to activate the HAP function.
2. **Start Pairing:**
   * Open the **HomeKit** app on your **iOS** device.
   * Scan the **QR code** displayed on the screen to pair the **nomos system Controller** with HomeKit.
3. **Alternatively: PIN Code:**
   * If you cannot scan the QR code, you can manually enter the displayed **PIN code** into your HomeKit app to establish the connection.
4. **Status of Devices:**
   * The current status shows how many devices from the nomos platform are currently connected to **Apple HomeKit**. For example: “13 out of 149 devices are in use.”
5. **Reset Pairing:**
   * To reset the HomeKit pairing, click the red Reset button if you want to reconfigure the connection to Apple HomeKit.
6. **Set Up HomeKit App:**

   * Once the QR scan (or PIN) has been successfully paired with the HomeKit app, you can continue the integration in the Apple HomeKit app.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://documentation.nomos-system.com/nomos-system/integrator-en/skills/hap-apple-homekit.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
