Understanding Your Aqara Doorbell and Compatibility

Types of Aqara Doorbells Available

The Aqara ecosystem offers several doorbell models, but the most popular and widely used is the Aqara Video Doorbell G2H (Pro). This model supports both wired and wireless installations, making it ideal for retrofitting into existing doorbell setups. It features 1080p HD video, night vision, motion detection, and compatibility with Apple HomeKit, Amazon Alexa, and Google Assistant via the Aqara Hub. Another option is the Aqara Doorbell H1 (Wireless), which is battery-powered and designed for homes without existing wiring. While this guide focuses on connecting the G2H model to a traditional doorbell circuit, the principles apply to other models with slight modifications.

Before you begin installation, it’s crucial to identify which model you have. The G2H comes with a chime unit (also called a “doorbell chime adapter” or “relay”), which is essential for integration with existing mechanical or electronic chimes. The H1, on the other hand, relies on Wi-Fi and a smart speaker or phone notification for alerts. Always check your package contents: the G2H includes the camera unit, mounting bracket, chime unit, screws, wire connectors, and a quick start guide.

Assessing Your Current Doorbell System

Not all doorbell systems are created equal. To ensure a smooth connection, you need to determine the type of doorbell circuit in your home. Most traditional homes use one of two setups:

• Mechanical Chime (Tubular or Bell Type): These use a physical striker to hit a metal bar or bell. They typically operate at 8–24 volts AC.
• Electronic Chime (Digital or Chime Module): These play a recorded tone or melody and may require a constant power supply (transformer) and a momentary switch (the doorbell button).

You can identify your system by listening to the chime sound or checking the transformer voltage. The Aqara Doorbell G2H is designed to work with both types, but the wiring method differs slightly. For mechanical chimes, you’ll connect the Aqara chime unit in parallel with the existing chime. For electronic chimes, you may need to bypass the internal electronics or use the chime unit as a relay to trigger the original chime.

Checking Voltage and Power Requirements

The Aqara Doorbell G2H requires a stable power source between 8–24 volts AC. Most residential doorbell transformers output 16V AC, which is ideal. To check your voltage:

1. Turn off power at the circuit breaker.
2. Remove the existing doorbell button and disconnect the wires.
3. Use a multimeter to measure the voltage across the two wires. If it reads between 8V and 24V AC, you’re good to go. If it’s below 8V, your transformer may be underpowered or degraded.

Tip: If your voltage is too low, consider replacing the transformer with a higher-rated one (e.g., 24V 30VA). Never use a DC power supply—Aqara doorbells are designed for AC only. Using the wrong voltage can damage the device or cause erratic behavior.

Step-by-Step Installation Guide

Tools and Materials You’ll Need

Before starting, gather the following:

• Aqara Doorbell G2H and chime unit
• Screwdrivers (Phillips and flathead)
• Wire strippers
• Wire nuts or Wago connectors
• Voltage tester (multimeter or non-contact tester)
• Drill and drill bits (if mounting on brick or stucco)
• Level (for precise alignment)
• Smartphone or tablet with Aqara Home app installed

Having these tools ready will make the process faster and safer. Always wear safety goggles when drilling or working near electrical components.

Disconnecting the Old Doorbell Button

Start by turning off power to the doorbell circuit at the breaker. Confirm it’s off using a non-contact voltage tester at the doorbell wires. Once safe, remove the old doorbell button by unscrewing it and gently pulling it away from the wall. Disconnect the two wires (usually labeled “Front” and “Trans”) and cap them with wire nuts to prevent accidental contact.

Pro Tip: Take a photo of the wiring before disconnecting. This serves as a reference if you need to revert or troubleshoot later. Label the wires with tape if possible (e.g., “Front” and “Trans”).

Mounting the Aqara Doorbell Camera Unit

Choose a location that provides a clear view of your doorstep—typically 48–52 inches from the ground. Use the included mounting template to mark screw holes. Drill pilot holes, insert wall anchors (if needed), and attach the mounting bracket with screws. Ensure it’s level using a spirit level.

Next, connect the two doorbell wires to the terminals on the back of the Aqara camera unit. The terminals are labeled “L” (Live) and “N” (Neutral), but polarity does not matter—AC current is not directional. Tighten the screws securely, but don’t over-tighten. Slide the camera unit onto the bracket and lock it in place.

Installing the Chime Unit (Relay Module)

The chime unit is the key to making your existing doorbell chime work with the Aqara Doorbell. It acts as a relay, allowing the camera to send a signal to your original chime without drawing too much current.

Locate your chime box (usually inside the house, near the front door). Open it and identify the “Front” terminal (connected to the front doorbell button). Disconnect the wire from this terminal and connect it to the “NO” (Normally Open) terminal on the Aqara chime unit. Then, run a new wire from the “COM” (Common) terminal on the chime unit back to the “Front” terminal on the chime box. This creates a parallel circuit—when the Aqara camera sends a signal, the chime unit closes the circuit and triggers the chime.

Example: In a home with a mechanical chime, the Aqara chime unit mimics the action of pressing the old doorbell button. For electronic chimes, the same principle applies, but ensure the chime unit is rated for the chime’s voltage and current (Aqara’s chime unit supports up to 24V AC, 1A).

Powering On and Initial Setup

Turn the power back on at the breaker. The Aqara Doorbell camera should power up within 30 seconds. A blinking blue light indicates it’s ready for setup. Open the Aqara Home app on your smartphone, tap “Add Device,” and select “Video Doorbell G2H.” Follow the on-screen instructions to connect to your Wi-Fi network (2.4 GHz only—5 GHz is not supported).

During setup, you’ll be prompted to pair the chime unit. The app will guide you through scanning the QR code on the chime unit or manually entering its ID. Once paired, test the system by pressing the Aqara Doorbell button. You should hear your original chime ring and receive a notification on your phone.

Configuring the Aqara Home App for Optimal Use

Pairing with the Aqara Hub (If Applicable)

While the G2H can function standalone, pairing it with an Aqara Hub M1S or M2 unlocks advanced features like HomeKit Secure Video, local storage, and integration with other Aqara sensors (motion detectors, door/window sensors). To pair:

1. In the Aqara Home app, tap the hub and select “Add Subdevice.”
2. Put the hub in pairing mode (usually by pressing and holding a button).
3. Follow the prompts to connect the doorbell to the hub’s Zigbee network.

Once connected, you can set up automations—e.g., “When the doorbell rings, turn on the porch light” or “If motion is detected, record a 30-second clip.”

Customizing Notifications and Alerts

By default, the app sends push notifications for every doorbell press and motion event. To avoid alert fatigue, customize your settings:

• Notification Schedule: Set quiet hours (e.g., 10 PM to 7 AM) to disable chimes or notifications.
• Motion Detection Zones: Use the app to draw zones where motion should trigger alerts (e.g., your driveway, not the street).
• Sensitivity Adjustment: Reduce false alarms from passing cars or animals by lowering sensitivity.
• Smart Alerts: Enable “Person Detection” to receive alerts only when a person is detected, not just any movement.

Tip: Use the “Do Not Disturb” mode during parties or when expecting frequent deliveries to mute notifications temporarily.

Setting Up Two-Way Audio and Video Recording

The Aqara Doorbell supports real-time two-way communication. When someone rings the doorbell, tap the notification to open the live view. You can speak through the app, and your voice plays through the doorbell’s speaker. This is useful for giving delivery instructions or greeting guests remotely.

For video recording, you have three options:

1. Cloud Storage (Subscription Required): Stores encrypted clips for 7–30 days (depends on plan).
2. MicroSD Card (Up to 512GB): Local storage—no subscription needed. Insert the card into the chime unit.
3. HomeKit Secure Video: If using an Aqara Hub and Apple devices, clips are stored in iCloud and analyzed on-device for privacy.

Note: Cloud and HomeKit options require a stable internet connection. Local storage works even during outages.

Troubleshooting Common Connection Issues

Doorbell Not Powering On

If the camera doesn’t light up after installation:

• Verify power is on at the breaker.
• Check voltage at the doorbell wires (should be 8–24V AC).
• Ensure wires are securely connected to the camera terminals.
• Test the chime unit with a multimeter to confirm it’s receiving power.

Common Fix: A loose wire is the most frequent culprit. Re-tighten all connections and use wire nuts for extra security.

Chime Not Ringing

If the camera works but the chime doesn’t sound:

• Confirm the chime unit is properly wired in the parallel circuit (NO to chime, COM to “Front” terminal).
• Check if the chime unit’s LED blinks when the doorbell is pressed (indicates signal sent).
• Test the original chime with a temporary wire across its terminals—if it doesn’t ring, the chime may be faulty.

Example: One user reported their chime only worked when the Aqara app was open. The issue was resolved by updating the chime unit’s firmware via the app.

Wi-Fi Connection Problems

The G2H requires a strong 2.4 GHz signal. If setup fails or the camera disconnects frequently:

• Move your router closer or install a Wi-Fi extender.
• Reduce interference from other devices (microwaves, cordless phones).
• Reboot the router and retry setup.
• Ensure the doorbell is within 30 feet of the router with minimal obstructions.

Pro Tip: Use a Wi-Fi analyzer app to check signal strength at the doorbell location. A signal below -70 dBm may cause issues.

False Motion Alerts or Poor Night Vision

Adjust the motion detection settings as described earlier. For night vision, ensure the camera’s IR sensors aren’t blocked by dirt, spider webs, or the mounting bracket. Clean the lens monthly with a microfiber cloth.

Advanced Integration and Smart Home Automation

Connecting to Apple HomeKit, Alexa, and Google Home

To use voice assistants:

• HomeKit: In the Aqara app, enable “HomeKit Mode.” Scan the HomeKit QR code on the doorbell or hub. Add it to the Home app.
• Amazon Alexa: Link your Aqara account in the Alexa app. Discover devices and assign the doorbell to a room.
• Google Home: Use the Google Home app to link Aqara and enable “Doorbell Press” routines.

Once integrated, you can say, “Alexa, show me the front door,” or “Hey Google, who’s at the door?”

Creating Automations and Scenes

Use the Aqara app to build automations:

• When the doorbell rings, turn on the porch light for 5 minutes.
• If motion is detected at night, send a notification and record a 10-second clip.
• When the doorbell is pressed, send a message to your smartwatch.

Example: A homeowner set up an automation so that when the Aqara Doorbell detects a person, it turns on the hallway lights and plays a custom chime on their Echo Dot.

Using with Other Aqara Devices

Pair the doorbell with Aqara sensors for a fully automated home:

• Aqara Motion Sensor: Trigger recording when someone approaches the door.
• Aqara Door/Window Sensor: If the front door opens after a ring, send an alert.
• Aqara Smart Plug: Turn on a welcome light when motion is detected.

This creates a layered security system that responds to real-time events.
