A blinking red light on your Blink doorbell typically indicates that it's in a state of readiness for setup or re-pairing, or that it's experiencing a power issue. If it's blinking red but failing to connect, the problem usually lies with the connection process itself, the doorbell's power source, or the network configuration.
Understanding the Blinking Red Light
When your Blink doorbell blinks red, it often signals one of two primary conditions:
- Ready for Setup/Pairing: After a battery replacement or a successful reset, a red flashing light indicates the doorbell is in pairing mode and ready to be discovered and added to your Blink account via the app.
- Power Issue: In some cases, a red light can also be an early indicator of low or insufficient battery power, which can prevent it from establishing a stable connection.
Common Reasons for Connection Failure
Even when the doorbell is blinking red, indicating it's ready, several factors can prevent it from successfully connecting:
- Insufficient Power: While it might blink red, the batteries may not have enough charge to sustain a full connection process.
- Incomplete Reset: The doorbell might not have been fully reset, or the reset procedure wasn't followed correctly to prepare it for connection.
- Sync Module Issues: The Blink Video Doorbell requires a Sync Module to operate. If the Sync Module is offline, too far away, or not properly configured, the doorbell won't connect.
- Wi-Fi Network Problems: Incorrect Wi-Fi credentials, a weak signal, network congestion, or incompatible Wi-Fi settings (e.g., 5GHz network when only 2.4GHz is supported) can hinder connection.
- App Setup Errors: Mistakes during the in-app setup process can lead to connection failures.
Troubleshooting Steps to Connect Your Blinking Red Blink Doorbell
To resolve the connection issue, follow these systematic troubleshooting steps:
1. Address Power and Reset the Doorbell
Ensure your doorbell has adequate power and is properly reset to enter pairing mode.
-
Check and Replace Batteries:
- Remove and reinsert the existing batteries. Sometimes, a simple reseating can re-establish contact.
- If the red LED still flashes after reinserting batteries, proceed to reset.
- Try new batteries. If there's no red LED flash at all, or if the red LED flashes but it still won't connect, install a fresh set of high-quality 1.5V AA lithium batteries. This ensures the doorbell has sufficient power for the connection process.
-
Perform a Hard Reset:
- With the batteries installed, locate the Reset button on the back of the doorbell.
- Press and hold the Reset button for five seconds. This action clears previous connection data and prepares the doorbell for a new setup.
- Once the reset is complete, the red LED should flash, indicating it's ready to be added to your Blink account.
2. Verify Your Sync Module and Wi-Fi Network
The doorbell needs to communicate with a Sync Module, which then connects to your home's Wi-Fi.
- Ensure Sync Module is Online and Close By:
- Check that your Blink Sync Module is plugged in, powered on, and has a solid blue and solid green light, indicating it's online and connected to your Wi-Fi.
- Place the Sync Module within a reasonable distance (typically 10-20 feet) of the doorbell during the setup process to ensure a strong signal. You can move it back later if needed.
- Check Wi-Fi Network Details:
- Confirm your Wi-Fi name (SSID) and password are correct. Even a single typo can prevent connection.
- Ensure your Wi-Fi network is 2.4 GHz, as Blink devices typically do not support 5 GHz networks.
- Verify Wi-Fi signal strength at the doorbell's installation location. Use your phone to check the Wi-Fi bars in that area. Weak signals can cause intermittent connectivity or failure to connect.
3. Re-attempt Setup via the Blink App
Once the doorbell is reset and ready, and your network is verified, try adding it again through the app.
- Remove Existing Doorbell (if applicable): If the doorbell was previously added to your account, even if it was offline, remove it from the Blink app first. Go to device settings and select "Delete Device."
- Initiate "Add Device" in App:
- Open the Blink Home Monitor app.
- Tap the "+" icon (Add Device) on the home screen.
- Select "Blink Video Doorbell" from the list of devices.
- Follow the on-screen instructions carefully, scanning the QR code or manually entering the serial number when prompted.
- During the setup, the app will guide you through connecting the doorbell to your Sync Module and then to your home Wi-Fi.
4. Additional Considerations
- Reduce Interference: Other wireless devices or large metal objects near the doorbell or Sync Module can cause interference. Try to minimize these during setup.
- Router Settings: Check your router's settings. Sometimes, strict firewall settings or MAC filtering can block new devices. Temporarily disabling these during setup might help, but remember to re-enable them afterward.
- App and Firmware Updates: Ensure your Blink app is updated to the latest version and that your Sync Module's firmware is also current.
By systematically addressing power, resetting the doorbell, verifying your network, and carefully following the app's setup process, you should be able to get your Blink doorbell connected.
