Understanding Your Aqara Doorbell Model and Components

Identifying Your Aqara Doorbell Model

Before you begin the reinstallation process, it’s essential to identify your specific Aqara doorbell model. Aqara offers several variants, each with slightly different mounting mechanisms and connectivity requirements. The most common models include:

• Aqara Video Doorbell G2H (Wired): Requires a constant power supply via existing doorbell wiring. Features HD video, night vision, and local storage.
• Aqara Door and Window Sensor with Chime (Battery-Powered): Uses a magnetic sensor and wireless chime. Often paired with a separate camera or hub.
• Aqara Video Doorbell G2H Pro (Wired): An upgraded version with improved audio, wider field of view, and enhanced motion detection.
• Aqara Smart Doorbell (Zigbee-based, Battery-Powered): Relies on a Zigbee hub (like Aqara Hub M1S) for connectivity and doesn’t require Wi-Fi directly.

Knowing your model helps you determine whether you’re dealing with a wired or wireless installation, which tools you’ll need, and how to reconnect it to your smart home system.

Essential Components and Tools

To successfully reattach your Aqara doorbell, gather the following components and tools:

• Original mounting bracket or plate (included with the doorbell)
• Mounting screws and wall anchors (usually provided, but replacements are available at hardware stores)
• Small Phillips-head screwdriver or electric screwdriver
• Spirit level (to ensure the doorbell is straight)
• Drill (if you need to make new holes in the wall)
• Smartphone or tablet with the Aqara Home app installed
• Access to your Aqara Hub (if using Zigbee models)
• Wi-Fi network details (SSID and password, for Wi-Fi models)
• Optional: Silicone sealant (for outdoor installations to prevent water ingress)

Tip: If you’ve misplaced the original screws or bracket, check the Aqara website or contact customer support for replacement parts. Most mounting kits are standardized, and third-party options are also available.

Assessing the Installation Site

When reattaching your doorbell, evaluate the installation site for:

• Structural integrity: Ensure the wall or door frame can support the doorbell’s weight.
• Weather exposure: Outdoor installations should avoid direct rain or extreme heat. Use a protective cover if necessary.
• Signal strength: For wireless models, ensure the location has strong Wi-Fi or Zigbee coverage. Use a signal strength checker app or your phone’s Wi-Fi analyzer.
• Field of view: The camera should cover the approach path to your door without obstructions (e.g., overgrown plants).

Reinstalling in the same spot as before is ideal, but if you’re relocating, take time to plan the new position carefully.

Step 1: Prepare the Mounting Surface and Hardware

Clean and Inspect the Mounting Area

Begin by cleaning the area where the doorbell will be installed. Remove any dust, dirt, or old adhesive residue. If you’re reusing existing screw holes, inspect them for wear or damage. Over time, drywall anchors can loosen, especially with frequent temperature changes or vibrations from door use. If the holes are stripped or the anchors are loose, it’s best to:

• Remove the old anchors completely.
• Fill the holes with a wall repair compound (e.g., spackle) and let it dry.
• Drill new pilot holes and install fresh anchors.

For brick, stucco, or concrete walls, use masonry anchors and a hammer drill for best results.

Align the Mounting Bracket

Place the Aqara mounting bracket against the wall at the desired height (typically 48–52 inches from the ground, aligning with standard doorbell placement). Use a spirit level to ensure the bracket is perfectly horizontal. Mark the screw hole positions with a pencil. If your bracket has alignment guides or templates (as seen on the G2H models), use them to ensure precise placement.

Practical Example: For the Aqara G2H Pro, the bracket has a built-in level indicator. Align the bubble in the center of the vial to ensure the doorbell won’t tilt forward or backward, which could affect camera angle and motion detection.

Secure the Bracket with Screws

Drill pilot holes at the marked positions, then insert the wall anchors. Attach the mounting bracket using the provided screws. Tighten them firmly, but avoid over-torquing, which can strip the plastic or damage the bracket. For outdoor installations, apply a small bead of clear silicone sealant around the screw holes and edges of the bracket to prevent water infiltration.

Tip: If you’re installing on a metal surface (e.g., a steel door), use self-tapping screws and a drill bit designed for metal to prevent slipping.

Step 2: Reconnect Power and Attach the Doorbell

For Wired Models (G2H, G2H Pro)

If you have a wired Aqara doorbell, power reconnection is crucial. Follow these steps:

1. Turn off the circuit breaker for your existing doorbell to avoid electric shock.
2. Remove the old doorbell or disconnect the wires from the mounting plate.
3. Identify the transformer wires (usually labeled “Front” and “Trans” or “Common” and “Front”).
4. Connect the Aqara doorbell’s power wires to the existing doorbell wires using wire nuts. Match the colors (typically red to red, white to white).
5. Ensure no bare wires are exposed. Push the connections into the wall cavity.
6. Turn the breaker back on and verify power by checking if the doorbell’s LED lights up.

Safety Note: If you’re unsure about electrical work, consult a licensed electrician. Most doorbell transformers output 8–24V AC, which is low voltage but still requires caution.

For Battery-Powered Models (Smart Doorbell, Door/Window Sensor with Chime)

Battery-powered models don’t require wiring, but you must:

• Insert fresh CR123A or AAA batteries (depending on the model) into the doorbell unit.
• Ensure the battery compartment is clean and the contacts are free of corrosion.
• Press the reset button (if available) to ensure the device is in pairing mode.

Once powered, attach the doorbell unit to the mounting bracket. Most Aqara models use a magnetic or snap-in mechanism. For example, the G2H Pro has a locking tab—slide the doorbell onto the bracket and push it down until you hear a click.

Verify Physical Attachment

After attaching, gently tug on the doorbell to ensure it’s securely fastened. If it wobbles, tighten the mounting screws or check that the locking mechanism is fully engaged. A loose doorbell can lead to false motion alerts or damage over time.

Step 3: Reconnect to Your Smart Home Ecosystem

Reconnecting via the Aqara Home App

Open the Aqara Home app on your smartphone. If the doorbell was previously paired, it may appear as an “offline” device. Tap on it and follow the on-screen instructions to re-establish the connection. For new setups or factory resets:

1. Tap the “+” icon in the app and select “Add Device.”
2. Choose your doorbell model from the list.
3. Follow the prompts to scan the QR code on the doorbell or enter the pairing code.
4. For Wi-Fi models: Select your Wi-Fi network and enter the password.
5. For Zigbee models: Ensure your Aqara Hub is online and in pairing mode.

Tip: If the app doesn’t detect the doorbell, restart the app and ensure Bluetooth is enabled on your phone (for initial pairing).

Troubleshooting Connection Issues

Common reconnection problems and solutions:

• Wi-Fi models won’t connect to network: Ensure your router supports 2.4 GHz (Aqara doorbells do not support 5 GHz). Move the router closer or use a Wi-Fi extender.
• Zigbee doorbell not found by hub: Reset the doorbell (press and hold the reset button for 10 seconds), then restart the hub. Ensure the hub is within 10–15 feet of the doorbell.
• App shows “Device Offline”: Check power (wired models) or replace batteries (wireless). Reboot your router and hub.

Syncing with Other Smart Devices

Once connected, reconfigure automations. For example:

• Link the doorbell to a smart light to turn on when motion is detected.
• Set up notifications on your smartwatch or Alexa/Google Assistant.
• Adjust motion detection zones to avoid false alerts from passing cars.

Test these integrations by triggering the doorbell or simulating motion.

Step 4: Test and Calibrate the Doorbell

Video and Audio Testing

Open the Aqara Home app and access the live view. Check:

• Video quality (HD, night vision, field of view).
• Audio clarity (two-way talk, chime volume).
• Motion detection (wave your hand in front of the camera).

Adjust the camera angle by slightly rotating the mounting bracket if needed. For G2H models, the camera has a swivel mechanism—loosen the screw, reposition, and retighten.

Chime and Notification Testing

Press the doorbell button to test the chime. If using a wireless chime (e.g., Aqara Smart Plug or Chime), ensure it’s powered and within range. Check that push notifications arrive on your phone within 2–3 seconds.

Tip: For wired models, test the indoor chime by connecting it to the doorbell’s chime terminals (if supported).

Calibration and Settings Optimization

Fine-tune settings in the app:

• Adjust motion detection sensitivity (lower for busy streets).
• Set recording schedules (e.g., only at night).
• Enable AI-based person detection to reduce false alerts.
• Update firmware to the latest version for improved performance.

Step 5: Long-Term Maintenance and Best Practices

Regular Cleaning and Inspection

Clean the camera lens and motion sensor with a soft, lint-free cloth monthly. Remove cobwebs or debris that could block the view. For outdoor units, inspect the sealant annually and reapply if cracked.

Firmware and Security Updates

Enable automatic updates in the Aqara app. Regular updates patch security vulnerabilities and add new features. Check for updates every 2–3 months.

Backup and Redundancy

For critical installations, consider:

• Using local storage (microSD card) as a backup to cloud recordings.
• Keeping spare batteries or a power bank for wireless models.
• Documenting your Wi-Fi password and hub IP address for quick recovery.
