Steps

Goal: Confirm the symptom, rule out Wi-Fi and power, then fix app notifications or chime setup.

  • Press the doorbell button. Note whether the in-home chime, phone app alert, or both fail.
  • Good: You know which part fails. Proceed to Check Wi-Fi and power.
  • Bad: Both work—no fix needed. If intermittent, retest.

Check Wi-Fi and power

Goal: Rule out connection and power before changing chime settings.

  • Open the doorbell app and confirm the device shows online. If offline, the doorbell has no power or no Wi-Fi.
  • Battery models: charge or replace the battery. Wired models: check the transformer output (16–24 V AC typical) with a multimeter.
  • Power-cycle: battery—remove, wait 30 seconds, reinsert; wired—turn off breaker 30 seconds, turn on. Recheck the app.
  • Good: Doorbell shows online. Proceed to App notifications.
  • Bad: Stays offline—check Wi-Fi signal, router placement, and power. Contact support if it still will not connect.

App notifications

Goal: Confirm you receive phone alerts when the button is pressed.

  • Open the doorbell app and go to device settings. Confirm push notifications are enabled.
  • Check your phone: Do Not Disturb, app notification permissions, and notification sound. None should block alerts.
  • Good: Notifications enabled and you get alerts. If the chime still does not ring, go to Chime setup.
  • Bad: No app alerts—fix notifications in app and phone settings, then retest.

Chime setup

Goal: Fix the in-home chime—mechanical, wireless, or smart speaker.

  • Mechanical chime: The doorbell needs a power kit installed at the chime box. Check your owner’s manual or search “[brand] [model] power kit install.” The kit prevents the doorbell from drawing too much power from the chime. If missing or wrong, install per the manual.
  • Wireless chime: Confirm it is paired in the doorbell app and powered (battery or plug-in). Check volume is not muted. Re-pair in the app if needed.
  • Smart speaker: Confirm the doorbell skill or integration is enabled and the doorbell is linked. Check speaker volume and that announcements are not muted.
  • Good: Chime rings when you press the button.
  • Bad: Chime still does not ring—confirm power kit wiring (mechanical), pairing (wireless), or link (smart speaker). Contact support if correct and it still fails.

When to get help

Contact the doorbell manufacturer or call a pro (electrician for wiring) if:

  • The device stays offline after power-cycling and Wi-Fi checks.
  • The mechanical chime does not ring after installing the power kit correctly.
  • You have replaced the battery or transformer and it still does not ring.
  • The app shows an error code.

Have your model number and what you have tried ready.

Verification

  • The doorbell shows online in the app.
  • You receive a phone notification when the button is pressed.
  • The in-home chime (mechanical, wireless, or smart speaker) rings when the button is pressed.
  • No error codes in the app.
