Power issues

You might have a power issue if you notice any of the following:

• Your doorbell doesn't power on when connected to a compatible power source, or you see a flashing red light.
• Your doorbell loses power at night or after the button is pressed.
• Certain features can't be toggled on in the Blink app.
• A poor power rating is shown in the Blink app.

Wiring

If your Wired Doorbell 2K+ isn't responding after hardwiring, the mounting plate may not be fully flush against the wall, or the terminal screws may be overtightened. Either issue can prevent the wires from making a proper connection.

To resolve this:

• Verify that the mounting plate is flat and flush against the wall.
• Loosen any overtightened terminal screws and re-secure the wires firmly, but not too tight.
• Double-check each wire is under the correct terminal screw by referring to the hardwiring instructions for your device.

Transformer requirements

Your Wired Doorbell 2K+ requires the following power from your transformer:

• Voltage: 12–24V (US/CA) 8-24V (EU/UK)
• VA rating: 10–40 VA

f your current transformer does not meet these requirements, it will need to be replaced. We recommend consulting a qualified professional for transformer replacement. Note: Using non-approved power sources, can damage your device.

To locate your transformer, turn off power at the circuit breaker first. Transformers are typically small metal boxes found in garages, basements, attics, or closets.

Chime issues

If you're experiencing issues with your chime, try these solutions:

Check compatibility: Verify that your chime is compatible with the Wired Doorbell 2K+. Confirm that all wires are secured under the correct terminal screws.

Chime rings continuously or spontaneously: This is typically caused by a wiring issue. Check that the bypass wire is correctly installed.

Chime buzzes or hums: This usually indicates a power mismatch or a wiring issue. First, verify that your bypass wire is installed correctly. Then, confirm that your transformer's voltage and VA rating meet the requirements for your doorbell and chime. Replace the transformer if necessary. If you're uncomfortable doing this yourself, consult a licensed professional.

Verify your device health

Your Blink app shows a power rating for your doorbell under Device Health. Use this to quickly diagnose power issues before trying other troubleshooting steps.

1. From the Home Screen of your Blink app, tap the More (...) button on your Wired Doorbell 2K+ thumbnail.
2. Tap Device Settings.
3. Tap Device Health.

Not receiving motion notifications

Two key requirements must be met to receive motion notifications:

1. From the Home Screen of your Blink app, verify that the system where your doorbell is added is Armed.
2. From the Home Screen of your Blink app, tap the More (...) button on your Wired Doorbell 2K+ thumbnail, and ensure Motion Detection is On.

If you're still not receiving alerts, visit Troubleshooting Motion Notifications.

Reducing excessive motion notifications

If you're getting too many motion notifications:

• Adjust Sensitivity Settings
  To minimize false notifications triggered by blowing leaves, moving shadows, or small animal movements, reduce the sensitivity setting by two points initially. Keep in mind that lower sensitivity requires more significant movement to trigger alerts, allowing you to fine-tune the balance between responsiveness and false motion.
  
  
• Set Up Activity Zones
  Customize your monitoring zones. This helps avoid unwanted notifications from busy areas like sidewalks or streets, keeping your notifications relevant to what matters to you.
