Xfinity Home alerts (Answered)

Your Xfinity Home system lets you know if there's a problem with a device connected to your alarm system. You’ll receive Xfinity Home alerts notifying you when a device or connection needs attention. Learn more about managing alert messages and potential resolutions below.

Is your Xfinity Home system offline?

What you'll need:

  • Xfinity Home
  • Access to your Xfinity Home touchscreen

Xfinity Home alerts

Alerts let you know when a device or connection in your Xfinity Home alarm system needs attention. You can manage these alerts on the Xfinity Home app and Xfinity Home touchscreen. See how to manage these alerts below. These alerts are different than alarms and notifications you receive informing you of activity in your home. These alerts notify you have an issue with your alarm system and devices.

Xfinity Home app

The alert icon (triangle with exclamation point) appears in the upper-right corner of the Overview screen.

  • The number in the red circle tells you how many issues are active (not snoozed).

  • Tap the icon to open All Alerts and get more information.

Touchscreen

  • Some touchscreens display an alert icon (triangle) on the upper right.
  • Some touchscreens display a blue dot that appears in the Notification Center (circle) in the upper-left corner of the screen.
    • The blue dot disappears when alerts are read and reappears every four hours if the problem remains unresolved.
  • A device screen will open the first time an alert sounds with information on how you can resolve the problem.
    • Tapping Learn More and navigating away from the screen automatically snoozes the alert.
  • The Alerts list will open when snooze expires on an unresolved problem.
    • Tap an alert from the list to open the message.
    • Non-critical problems remain snoozed and can be accessed from the Notification Center.

Note: Xfinity Home has a Do Not Disturb feature you can use to automatically mute the audible alert for most trouble messages. This prevents interruptions during times when you may be asleep or otherwise don't want to be disturbed. This feature doesn’t block or change your security or alarm settings — only the alerts related to issues with devices and their connection to your system.

Check if there's an outage

First things first — the problem might not be with your system. Before you try any fixes, check if there are service outages in your area.

Note: Your touchscreen has a battery backup, so you'll stay connected even in a power outage. However, if your cable service is out, your high-speed internet service will also be out, which will affect your Xfinity Home system. You'll still be protected, but you won't be able to view feeds from your cameras or control your system from the Xfinity Home app.

Check the power and connections

  • Make sure:
    • Devices are plugged in to working power outlets that aren't controlled by a light switch.
    • All power cords are securely connected to the devices.
    • A circuit breaker in your home hasn't tripped.
  • Check that all modem, router, gateway connections are secure.
  • Confirm your account is up to date.
    • Late payments can cause service interruptions.
  • If you're using the Xfinity Home app, make sure your phone can connect to the internet using WiFi.

If none of the above resolves the issue, check your connection to the internet.
