iSG natively supports adding Matter-over-WiFi devices (see Add Matter Devices). These devices will automatically sync to Home Assistant if your iSG is connected to HA (check Einstellungen > Local HA).
4.7. Matter Bridge
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 Installieren, and then switch Aktivieren on after installation.
After enabling the add-on, go to Home Assistant and click ADD on the discovered Matter integration.
