On your mobile device, open the Apple Home app and locate the adapter you wish to remove. Tap and hold on its device tile for 2 seconds and then release to bring up its menu.

Step 2:
Tap on the Settings (gear) icon to bring up the adapter's settings page.

Step 3:
Tap on Remove Accessory.

IMPORTANT: Removing the device from the Apple Home app will not remove it from your WiFi network nor will it remove any stored settings. If you want to factory restore your Belkin AUZ002, you can do it using the Belkin SOUNDFORM app.
