Preparing for Reinstallation: Tools, Safety, and Prerequisites

Before you begin the physical reinstallation of your Aqara Doorbell, it’s crucial to prepare adequately. A successful reinstallation depends not only on correct mounting but also on ensuring all technical and environmental conditions are met. Skipping this preparation phase can lead to recurring issues, such as poor signal strength, battery drain, or app disconnections.

Gather the Necessary Tools and Materials

Having the right tools on hand will make the process smoother and prevent damage to your doorbell or mounting surface. Here’s what you’ll need:

• Original mounting hardware (screws, wall anchors, mounting bracket) – these are typically included in the Aqara Doorbell box
• Phillips-head screwdriver or a small electric screwdriver
• Drill with a 3/16″ (5mm) drill bit for masonry or wood surfaces
• Level to ensure the doorbell is perfectly aligned
• Measuring tape to position the doorbell at optimal height (recommended: 48–52 inches from the ground)
• Smartphone or tablet with the Aqara app (iOS or Android) installed and updated
• Fully charged batteries (for battery-powered models like the G2H)
• Optional: Painter’s tape to mark drilling points without leaving residue

Pro Tip: If you’ve misplaced the original screws or bracket, contact Aqara support—they often provide replacement parts for free or at minimal cost.

Check Your Wi-Fi and Network Environment

Your Aqara Doorbell relies on a stable 2.4 GHz Wi-Fi connection. Before reinstalling, verify the following:

• Your router broadcasts a 2.4 GHz network (not just 5 GHz)
• The signal strength near the installation point is strong (use a Wi-Fi analyzer app to test)
• Your router supports WPA2 or WPA3 encryption (avoid WEP)
• No interference from thick walls, metal doors, or large appliances

For example, if you’re mounting the doorbell on a brick wall near a microwave, consider relocating your router temporarily or using a Wi-Fi extender to ensure a strong signal. A weak signal can cause frequent disconnections, delayed alerts, and poor video quality.

Ensure App and Firmware Are Up to Date

Before physically mounting the doorbell, update both the Aqara Home app and the doorbell’s firmware. Outdated software can cause pairing issues or prevent the device from connecting to your hub (like the Aqara Hub M1S or M2). To check for updates:

1. Open the Aqara app and go to Device Settings
2. Select your doorbell (if previously paired) or tap + Add Device if starting fresh
3. Navigate to Firmware Update and install any available updates
4. Restart the app after updating

Updating firmware not only improves performance but also adds new features and fixes known bugs related to connectivity and power management.

Step-by-Step Guide to Physically Mounting the Aqara Doorbell

With your tools ready and network verified, it’s time to reinstall the physical unit. This process varies slightly depending on your mounting surface (wood, brick, stucco, metal), but the core principles remain the same: secure, level, and weather-resistant.

Choose the Optimal Mounting Location

The location of your doorbell affects both usability and performance. Consider these factors:

• Height: Mount between 48 and 52 inches from the ground to capture faces clearly and reduce tampering risk
• Angle: Position it to face the walkway or porch, not directly into sunlight (to avoid glare in video)
• Distance from door: Place it 6–12 inches to the side of the door frame for easy access and visibility
• Weather protection: If possible, install under an eave or awning to protect against rain and direct sunlight

For example, if your front door is on a south-facing wall with afternoon sun, consider mounting the doorbell slightly to the west side to avoid lens flare during peak hours.

Mark and Drill Mounting Holes

Follow these steps to ensure precise drilling:

1. Hold the mounting bracket against the wall at the desired height
2. Use a level to ensure it’s perfectly horizontal
3. Mark the screw hole locations with a pencil or painter’s tape
4. Drill pilot holes using the appropriate bit for your surface:
   • Wood: 3/16″ bit, 1.5″ depth
   • Brick/Concrete: 3/16″ masonry bit, 2″ depth (use wall anchors)
   • Stucco: 1/4″ bit, 1.75″ depth (pre-drill slightly deeper to avoid cracking)

Caution: Always check for electrical wires or plumbing behind the wall using a stud finder with a wire detection feature before drilling.

Secure the Mounting Bracket

Once holes are drilled, insert wall anchors (if needed) and screw the bracket tightly into place. Use a screwdriver or drill on low torque to avoid stripping the screws. Ensure the bracket is flush with the wall and doesn’t wobble.

Pro Tip: For added security, especially in high-traffic areas, use tamper-resistant Torx screws (available from third-party vendors) to prevent unauthorized removal.

Attach the Aqara Doorbell Unit

Now, slide or snap the doorbell onto the mounting bracket. Most Aqara models use a magnetic latch system combined with a security screw. Here’s how:

1. Align the back of the doorbell with the bracket’s grooves
2. Push gently until it clicks into place (magnetic hold)
3. Insert the included security screw into the bottom hole and tighten lightly

Do not over-tighten—this can crack the plastic housing. The magnetic hold should be strong enough to resist casual tampering, while the screw prevents full removal.

Test Physical Stability

Gently tug on the doorbell to ensure it doesn’t move. If it wiggles, recheck the screws and bracket alignment. A stable mount prevents vibrations that can trigger false motion alerts.

Reconnecting the Aqara Doorbell to the Network and App

Physical installation is only half the battle. The next critical phase is reconnecting your doorbell to your Wi-Fi network and the Aqara ecosystem. This process ensures you can view live video, receive alerts, and control settings remotely.

Power Up the Doorbell

For battery-powered models (e.g., G2H):

• Insert fully charged batteries (Aqara recommends 18650 Li-ion cells)
• Press and hold the reset button (usually on the side or back) for 5–10 seconds until the LED flashes blue

For wired models (e.g., G3 with PoE or AC adapter):

• Connect the power adapter or PoE cable
• Wait for the LED to flash red/blue (pairing mode)

Note: The LED pattern indicates status:

• Solid blue: Connected to Wi-Fi
• Flashing blue: In pairing mode
• Flashing red: Low battery or connection issue
• Solid red: Charging

Pair with the Aqara App

Follow these steps in the Aqara Home app:

1. Open the app and tap + Add Device
2. Select Doorbell from the category list
3. Choose your specific model (e.g., G2H Pro)
4. Scan the QR code on the back of the doorbell or enter the pairing code manually
5. When prompted, enter your 2.4 GHz Wi-Fi network name (SSID) and password
6. Wait for the device to connect (usually takes 1–2 minutes)

If the connection fails:

• Ensure the password is correct (case-sensitive)
• Move closer to the router during setup
• Disable VPNs or ad blockers on your phone
• Restart the doorbell and retry

Reconnect to Your Smart Home Hub (If Applicable)

If you use an Aqara Hub (M1S, M2, or E1), you’ll need to re-add the doorbell to the hub for advanced features like local storage, automation, and HomeKit integration.

1. In the Aqara app, go to Hub Settings
