How to Remove Devices from Smart Home Manager

Why Removing Devices Matters

Unused or unknown devices on your network can introduce security risks, clutter your device list, and slow performance. Here’s how to remove devices from Smart Home Manager using top provider apps and smart hubs.

🛠️ AT&T Smart Home Manager

According to AT&T support, you can block or pause devices, but removal often requires a full factory reset of the router or device.

1. Open the Smart Home Manager app.
2. Go to Profiles & Devices and find the device.
3. To block it, use the toggle; to fully remove it, you’ll need to factory reset the router or device.

3. If still connected, change your Wi-Fi password to force removal.

   Xfinity support confirms you can delete disconnected devices under “Forget Device”.

For hubs like Google Home or SmartThings:

• Go to the Devices tab in the Google Home app
