Pre-Installation: Assessing Your Home and Gathering Tools

Evaluating Your Existing Doorbell System

Before you begin wiring your Aqara Doorbell, it’s essential to assess your current doorbell setup. Most homes have a traditional wired doorbell system consisting of a chime, transformer, and low-voltage wiring (typically 8–24V AC). The Aqara Doorbell is designed to work within this standard voltage range, but compatibility must be confirmed. Start by turning off the power to your doorbell circuit at the main electrical panel. This is a critical safety step—never work on live circuits.

Once the power is off, remove the existing doorbell button and inspect the wiring. You should see two wires (often red and white) connected to the back. Use a multimeter to check the voltage across these wires. The reading should fall between 8V and 24V AC. If the voltage is below 8V, the transformer may be undersized or failing. If it’s above 24V, you risk damaging the Aqara Doorbell. In such cases, consider upgrading your transformer to a 16V, 10–15VA unit—this is the recommended specification for optimal performance.

Gathering the Right Tools and Materials

To wire up your Aqara Doorbell, you’ll need the following tools and supplies:

• Voltage multimeter (to test existing wiring)
• Wire strippers and cutters
• Electrical tape or wire nuts
• Philips and flathead screwdrivers
• Drill and appropriate drill bits (for mounting)
• Fish tape (if routing new wires through walls)
• Low-voltage transformer (16V, 10–15VA) if replacement is needed
• Aqara Doorbell unit and included mounting hardware
• Smartphone with Aqara app installed

Pro Tip: If your home doesn’t have an existing doorbell circuit, you’ll need to install a transformer. This involves connecting it to a 120V AC power source (usually near your electrical panel or a nearby outlet) and running low-voltage wires to the doorbell location. While this is a more involved task, it’s manageable with basic electrical knowledge and proper safety precautions. Always consult a licensed electrician if you’re unsure.

Checking Compatibility with Your Smart Home Ecosystem

The Aqara Doorbell comes in different models, including the Aqara Video Doorbell G2H (Wired) and the Aqara Doorbell H1 (Wired). Both support Zigbee 3.0 and require an Aqara Hub (such as the M1S, M2, or Hub E1) to connect to your Wi-Fi network. Before purchasing, ensure you have a compatible hub. The Aqara app (available on iOS and Android) is your central control point for setup, firmware updates, and integration with voice assistants.

Additionally, check your Wi-Fi signal strength at the doorbell’s intended location. Aqara Doorbell requires a stable 2.4 GHz Wi-Fi connection. If the signal is weak, consider installing a Wi-Fi extender or mesh node near your front door. A strong connection ensures smooth video streaming and real-time notifications.

Step-by-Step Wiring Process

Step 1: Power Off and Remove Old Doorbell

Safety first: confirm that the power is off using your multimeter. Once verified, remove the existing doorbell button by unscrewing it from the wall. Carefully disconnect the two wires, noting their positions. Label them with tape if necessary (e.g., “Left” and “Right”) to avoid confusion during reconnection.

If your old doorbell had a chime, locate it (usually in a hallway or kitchen). Open the chime cover and disconnect the wires from the “Front” terminal. These wires run to the doorbell button and will be repurposed for your Aqara Doorbell. Leave the “Trans” and “Rear” terminals connected to the transformer and back doorbell (if applicable).

Step 2: Prepare the Wires for Aqara Doorbell

The Aqara Doorbell uses two wires for power and signal. Unlike some smart doorbells that require a “power kit” to bypass the chime, the Aqara Doorbell is designed to work with standard mechanical chimes. However, it’s recommended to install a chime bypass capacitor (sold separately or included in some kits) to prevent flickering or buzzing in the chime. This capacitor ensures stable voltage delivery to the doorbell while allowing the chime to function normally.

Strip about 1/2 inch (1.25 cm) of insulation from the ends of the two wires. If the wires are damaged or too short, use a wire nut and a short length of 18–22 gauge stranded wire to extend them. Twist the wires clockwise and secure with a wire nut. Wrap with electrical tape for added protection.

Step 3: Mount the Aqara Doorbell

The Aqara Doorbell comes with a mounting bracket and screws. Position the bracket at your desired height (typically 48 inches from the ground, eye level for most adults). Use a level to ensure it’s straight, then mark the screw holes. Drill pilot holes and secure the bracket with the provided screws.

For stucco, brick, or concrete surfaces, use masonry anchors and a hammer drill. The Aqara Doorbell is weather-resistant (IP55 rated), but avoid mounting it directly under a downspout or in areas with constant water exposure. A slight overhang or eave is ideal for protection.

Step 4: Connect the Wires and Attach the Doorbell

With the bracket in place, connect the two wires to the terminals on the back of the Aqara Doorbell. The terminals are typically labeled “L” (Left) and “R” (Right), but polarity is not critical—either wire can go to either terminal. Tighten the screws securely to ensure a good connection.

Once wired, gently snap the doorbell unit into the mounting bracket. Some models require a small screw to lock the unit in place—check your manual for specifics. Avoid overtightening, as this can crack the housing.

Step 5: Restore Power and Initial Power-Up

Turn the power back on at the electrical panel. The Aqara Doorbell should power up within 30–60 seconds. You’ll see LED indicators (usually blue or white) blinking, indicating it’s ready for setup. If the lights don’t come on, double-check your wiring, voltage, and transformer.

Example: One installer reported the doorbell not powering up. After troubleshooting, they discovered the transformer was only outputting 6V due to old wiring. Replacing the transformer with a 16V unit resolved the issue instantly.

Setting Up the Aqara App and Smart Features

Installing the Aqara App and Creating an Account

Download the Aqara Home app from the App Store or Google Play. Open the app and create an account using your email or phone number. Enable location services and allow notifications for real-time alerts.

Log in and tap the “+” icon to add a new device. Select “Doorbell” from the list of categories. The app will guide you through the pairing process. Make sure your smartphone is connected to the same Wi-Fi network (2.4 GHz) that the doorbell will use.

Pairing the Doorbell with the Aqara Hub

The Aqara Doorbell uses Zigbee, a low-power wireless protocol, to communicate with the hub. Press and hold the pairing button on the back of the doorbell (usually for 5–10 seconds) until the LED flashes rapidly. In the Aqara app, follow the on-screen instructions to search for the device.
