# Matter Bridge

iSG natively supports adding Matter-over-WiFi devices (see [**Add Matter Devices**](https://kb.linknlink.com/isg/using-isg/devices/adding-devices/add-matter-devices)). These devices will automatically sync to Home Assistant if your iSG is connected to HA (check **Settings > Local HA**).

However, if you prefer to add Matter devices directly in iSG's built-in Home Assistant, you’ll need to use this add-on.

This add-on is optional and not installed by default. To use it, go to the **Add-On** section, click **Install**, and then switch **Enable** on after installation.

After enabling the add-on, go to Home Assistant and click **ADD** on the discovered Matter integration.
