Why Properly Installing Your Aqara Doorbell Back Cover Matters

When it comes to smart home security, the Aqara Doorbell stands out as a reliable, feature-rich device that offers seamless integration with Apple HomeKit, Google Home, and Amazon Alexa. Whether you’re a tech-savvy homeowner or a DIY enthusiast, installing your Aqara Doorbell correctly ensures optimal performance, durability, and long-term reliability. One of the most critical yet often overlooked steps in the setup process is how to put the back cover on an Aqara Doorbell. This seemingly simple task can have a significant impact on the device’s functionality, weather resistance, and overall longevity.

Many users rush through the installation process, assuming that once the doorbell is mounted and powered, the job is done. However, the back cover—often referred to as the mounting plate or base plate—plays a vital role in securing the doorbell unit, protecting internal components from environmental elements, and ensuring a clean, professional finish. A poorly installed back cover can lead to loose connections, water ingress, signal interference, or even damage to the doorbell’s sensitive electronics. In this guide, we’ll walk you through how to put the back cover on an Aqara Doorbell in 5 easy steps, covering everything from preparation to troubleshooting common issues. Whether you’re replacing an old cover, upgrading your doorbell, or installing it for the first time, this guide will help you do it right—every time.

Understanding the Aqara Doorbell Back Cover and Its Components

What Is the Back Cover and Why Is It Important?

The back cover of the Aqara Doorbell is more than just a decorative piece. It serves multiple functional purposes:

• Secures the doorbell unit to the wall or mounting surface using screws or adhesive.
• Provides weather resistance by sealing the internal electronics from rain, dust, and humidity.
• Hides wiring for a clean, professional appearance.
• Acts as a grounding plate in some models to improve Wi-Fi and signal reception.

Without a properly installed back cover, your doorbell may become loose, suffer from connectivity issues, or even short-circuit during heavy rain. The Aqara Doorbell (models like the Aqara Video Doorbell G2H Pro or G3) typically uses a magnetic or screw-based back cover design, depending on the version.

Identifying Your Aqara Doorbell Model and Cover Type

Before attempting to install the back cover, it’s essential to identify your specific Aqara Doorbell model. Different models may have slightly different mounting mechanisms:

• Magnetic Back Cover: Found in newer models like the G3. Uses strong magnets to hold the doorbell in place, allowing for easy removal for charging or cleaning.
• Screw-Mounted Back Cover: Used in older or Pro versions. Requires screws to secure the doorbell and offers a more permanent installation.
• Adhesive-Only Mounting: Some kits include 3M adhesive strips for renters or those who prefer not to drill holes.

Check the model number on the original packaging or in the Aqara Home app under device settings. Knowing your model ensures you follow the correct installation method and use compatible accessories.

Tools and Materials You’ll Need

To successfully install the back cover, gather the following tools and materials:

• Aqara Doorbell back cover (included in the original kit or purchased separately)
• Screwdriver (usually Phillips #0 or #1—check your model’s manual)
• Drill and wall anchors (if mounting on brick, concrete, or stucco)
• Measuring tape or ruler
• Level tool (to ensure the doorbell is straight)
• Masking tape (for marking drill points)
• Optional: Silicone sealant (for added weatherproofing in high-exposure areas)

Having these tools ready before you start saves time and prevents interruptions during installation.

Step-by-Step Guide: How to Put Back Cover on Aqara Doorbell in 5 Easy Steps

Step 1: Prepare the Mounting Surface and Remove the Old Cover (If Applicable)

If you’re replacing an existing doorbell or upgrading your Aqara model, start by removing the old back cover. For screw-mounted models, use your screwdriver to unscrew the mounting plate. For magnetic models, gently twist and pull the doorbell unit away from the base—avoid using excessive force to prevent damaging the magnets or the doorbell’s housing.

Once removed, clean the surface with a damp cloth to remove dust, grease, or old adhesive residue. For new installations, choose a location:

• At eye level (approximately 4–5 feet from the ground)
• Near a power source (for wired models) or within Wi-Fi range (for battery-powered)
• Protected from direct rain or sprinklers, if possible

Use the back cover as a template to mark the screw holes or adhesive placement. Apply masking tape over the marked areas to prevent surface scratches during drilling.

Step 2: Secure the Back Cover to the Wall or Mounting Surface

This step varies slightly depending on your mounting method:

• For Screw-Mounted Covers: Drill pilot holes at the marked locations using a drill bit slightly smaller than your wall anchors. Insert the anchors, then align the back cover and drive the screws through the cover’s holes into the anchors. Do not overtighten—snug is sufficient.
• For Adhesive Mounting: Remove the protective liner from the 3M adhesive strips on the back of the cover. Press the cover firmly against the wall for 30–60 seconds to ensure a strong bond. Avoid repositioning after initial contact.
• For Magnetic Covers: The magnetic base plate is usually screw-mounted. Install it securely, then the doorbell will snap into place magnetically.

Use a level to check that the back cover is perfectly horizontal. An uneven mount can cause the doorbell to appear crooked or affect motion detection accuracy.

Step 3: Connect Wiring (For Wired Models) or Ensure Battery Is Charged (For Wireless)

If your Aqara Doorbell is wired (e.g., G2H Pro with transformer), now is the time to connect the wires:

• Strip the ends of the existing doorbell wires (if not already done).
• Connect the wires to the terminals on the back cover or doorbell unit (polarity is usually not critical for AC doorbells).
• Secure the wires behind the cover using built-in wire clips or zip ties to prevent strain.

For battery-powered models (e.g., G3), ensure the battery is fully charged before attaching the doorbell. A low battery can cause the device to disconnect or fail to power on after installation.

Step 4: Attach the Aqara Doorbell Unit to the Back Cover

Now, carefully align the doorbell unit with the back cover:

• Magnetic Models: Position the doorbell so that the magnets on the back cover align with those on the doorbell. Gently push until it clicks into place. The unit should sit flush with no wobbling.
• Screw-Mounted Models: Slide or snap the doorbell into the back cover, then secure it with the included security screw (usually located at the bottom). This screw prevents unauthorized removal.
• Adhesive Models: Press the doorbell firmly onto the adhesive-mounted cover. Wait 24 hours before heavy use to allow full adhesive curing.

After attachment, gently wiggle the doorbell to confirm it’s secure. Any looseness could indicate improper alignment or loose screws.

Step 5: Test the Doorbell and Finalize the Installation

Power on the doorbell (via transformer, battery, or USB) and follow the Aqara Home app setup process if not already completed. Perform the following tests:

• Press the doorbell button to verify it triggers a chime and sends a notification to your smartphone.
• Check the video feed for clarity and field of view.
• Test night vision and motion detection.
• Ensure the doorbell doesn’t rattle or move when pressed.

If everything works, use a small bead of clear silicone sealant around the edges of the back cover (especially on exterior walls) to enhance weatherproofing. Avoid covering screw holes or ventilation slots.

Common Mistakes and How to Avoid Them

Overtightening Screws

One of the most common errors is driving screws too tightly, which can crack the plastic back cover or strip the threads in wall anchors. Always tighten screws until snug—then stop. If the cover feels loose, use larger wall anchors or a different mounting surface.

Ignoring Weatherproofing

Even though the Aqara Doorbell is IPX3-rated for splash resistance, prolonged exposure to rain or snow can damage internal components. To avoid this:

• Install the doorbell under an eave, awning, or porch.
• Apply silicone sealant around the edges of the back cover.
• Avoid mounting directly above a downspout or sprinkler.

Incorrect Alignment

An off-center or crooked doorbell looks unprofessional and can affect motion detection. Always use a level during installation. If you’ve already mounted the cover and notice misalignment, remove it, reposition the marks, and reinstall.

Forgetting to Charge the Battery

Battery-powered models require regular charging. If the doorbell powers off immediately after installation, the battery may be depleted. Charge it using the included USB-C cable for at least 6 hours before reattaching.

Using Incompatible Accessories

Not all back covers are interchangeable. Using a third-party or wrong model-specific cover may result in poor fit, reduced weather resistance, or voided warranty. Always use genuine Aqara parts or certified replacements.

Advanced Tips for Optimal Performance and Longevity

Upgrade to a Weather-Resistant Mounting Kit

For homes in extreme climates, consider purchasing a weather-resistant mounting kit. These kits often include:

• Extended back covers with drip shields
• UV-protected materials
• Enhanced adhesive for high-moisture areas

Some third-party vendors offer custom mounts with built-in solar panels for continuous battery charging.

Use the Aqara Home App for Firmware Updates

After installation, open the Aqara Home app and check for firmware updates. Updated firmware can improve Wi-Fi stability, motion detection accuracy, and battery life. Firmware updates often address known issues with back cover recognition or magnetic attachment.

Schedule Regular Maintenance Checks

Every 3–6 months, perform a quick inspection:

• Check for loose screws or adhesive failure.
• Clean the lens and sensors with a microfiber cloth.
• Verify the doorbell’s connection in the app.
• Test the chime and notification settings.

Regular maintenance prevents small issues from becoming costly repairs.

Consider a Doorbell Cover or Housing

For added protection, install a decorative or protective doorbell housing. These covers shield the device from direct sunlight, hail, and vandalism while maintaining access to the button and camera.
