Understanding Aqara Doorbell Models and Requirements

Before diving into the wiring process, it’s essential to understand which Aqara doorbell model you have and what it requires to function properly. Aqara offers both wired and battery-powered doorbells, but this guide focuses specifically on the wired models, such as the Aqara Video Doorbell G2H (Wired), which require a constant power supply to operate continuously. Unlike battery-powered versions, wired doorbells eliminate the need for frequent charging and provide uninterrupted performance, especially for features like live streaming and motion alerts.

Key Models and Their Power Needs

The most common wired Aqara doorbell is the G2H (Wired), which operates on a 16–24V AC power supply—the same standard voltage used by most traditional mechanical doorbells. This compatibility makes it easier to retrofit into existing doorbell circuits without needing to install a new transformer. However, if your home uses a non-standard voltage (e.g., 12V or 24V DC), you may need a voltage converter or a replacement transformer to ensure proper operation.

Other models, such as the Aqara Doorbell H1 (Wired), also follow the same 16–24V AC standard. Always refer to the user manual or product specifications on the Aqara website to confirm voltage requirements for your specific model. Installing a doorbell with incorrect voltage can lead to malfunctions, reduced lifespan, or even permanent damage to the unit.

Compatibility with Existing Doorbell Systems

One of the major advantages of the Aqara wired doorbell is its compatibility with most North American and European doorbell circuits. If your home already has a mechanical doorbell (with a chime box inside), you can typically reuse the existing wiring and transformer. However, you must verify the following:

• Transformer voltage: Use a multimeter to measure the output of your doorbell transformer. It should read between 16 and 24 volts AC. If it’s below 16V, the doorbell may not power on; if it’s above 24V, it could damage the device.
• Wiring integrity: Inspect the existing wires for corrosion, fraying, or breaks. Damaged wires must be replaced or spliced with new 18–22 gauge bell wire.
• Chime compatibility: The Aqara doorbell can work with mechanical chimes, but some digital or “smart” chimes may not be compatible. Aqara provides a list of tested chimes—check their support site for details.

Pro Tip: If you’re unsure about your transformer, consider upgrading to a 16V/10VA transformer, a common and reliable choice for smart doorbells. These are widely available online or at hardware stores and cost between $15–$25.

Tools and Materials You’ll Need

Proper preparation is key to a successful installation. Having the right tools and materials on hand will save time, reduce frustration, and ensure a safe and professional result. Below is a comprehensive list of what you’ll need to wire your Aqara doorbell.

Essential Tools

• Screwdrivers: A Phillips #1 and flathead screwdriver for removing the old doorbell, mounting the new unit, and securing wires.
• Wire strippers: To strip insulation from the ends of the doorbell wires for a secure connection.
• Multimeter: Crucial for testing voltage at the doorbell location and transformer. A basic digital multimeter (around $20) is sufficient.
• Drill and drill bits: For making pilot holes in wood, brick, or stucco. Masonry bits are needed for stone or concrete exteriors.
• Fish tape or wire snake: Useful if you need to run new wires through walls or conduit.
• Voltage tester (non-contact): To confirm power is off before working on electrical circuits.
• Level: Ensures your doorbell is mounted straight and aligned properly.

Required Materials

• Aqara Video Doorbell (Wired): Confirm model and voltage compatibility.
• 18–22 gauge bell wire: If replacing old or damaged wires. Pre-tinned wire is easier to work with.
• Wire nuts or Wago connectors: For splicing wires safely. Wago lever connectors are preferred for their reliability and ease of use.
• Wall anchors and screws: Usually included with the doorbell, but extras are helpful for different wall types.
• Electrical tape: For insulating connections (though wire nuts are often sufficient).
• Optional: Silicone sealant: To seal the mounting area and prevent water ingress, especially in rainy climates.

Optional but Helpful

• Smartphone or tablet: For scanning the QR code during setup and using the Aqara Home app.
• Extension ladder: If your doorbell is mounted high on a two-story house.
• Work gloves and safety goggles: For protection during drilling and wiring.

Tip: Lay out all tools and materials before starting. This prevents interruptions and keeps the workflow smooth. Also, take photos of your existing setup before removing the old doorbell—this can be a lifesaver if you need to troubleshoot later.

Preparing Your Home for Installation

Installing a smart doorbell isn’t just about wiring—it also involves planning the location, ensuring network connectivity, and preparing your home’s infrastructure. A well-thought-out preparation phase ensures your Aqara doorbell functions optimally and integrates seamlessly into your smart home ecosystem.

Assessing the Installation Location

Choose a spot near your front door that:

• Is within 3–6 feet of the ground for optimal motion detection and video capture.
• Has a clear view of the approach path (sidewalk, driveway, etc.).
• Is protected from direct rain or snow, if possible. While Aqara doorbells are weather-resistant (IP54 rating), prolonged exposure to water can reduce lifespan.
• Is close to your home’s Wi-Fi router or has strong signal strength. Use a Wi-Fi analyzer app to check signal strength at the proposed location.

Example: If your front door is on the east side of the house and your router is on the west, consider installing a Wi-Fi range extender or using a mesh network to boost signal.

Checking Wi-Fi and Network Requirements

The Aqara doorbell requires a 2.4 GHz Wi-Fi network with a stable connection. It does not support 5 GHz networks, which are faster but have shorter range and poorer wall penetration. Ensure your router broadcasts a 2.4 GHz signal and that the signal strength is at least -65 dBm at the doorbell location. A signal below -70 dBm may result in poor video quality or frequent disconnections.

Also, make sure your router supports WPA2 or WPA3 encryption, as the Aqara app requires a secure network for setup. Disable any “guest network isolation” features that might block the doorbell from communicating with other smart devices.

Power and Circuit Verification

Before touching any wires, turn off power to the doorbell circuit at your home’s main electrical panel. Use a non-contact voltage tester to confirm the wires at the doorbell location are dead. Then, test the transformer output (usually located in the basement, utility closet, or garage) to ensure it’s within the 16–24V AC range.

If your transformer is undersized (e.g., 8V or 10V), it may not provide enough power, especially if you have a long wire run with voltage drop. In such cases, upgrade to a 16V/10VA or 24V/20VA transformer and ensure it’s properly grounded.

Pro Tip: Label the doorbell circuit in your electrical panel to make future maintenance easier. Use a label maker or masking tape with a permanent marker.

Step-by-Step Wiring Process

Now that you’ve prepared your tools, location, and circuit, it’s time to install the Aqara doorbell. Follow these steps carefully to ensure a safe and successful wiring process.

Step 1: Remove the Existing Doorbell

Turn off power at the main panel. Remove the cover of your current doorbell and unscrew it from the wall. Carefully disconnect the two wires (usually labeled “Front” and “Trans” or color-coded black and white). Use wire nuts to cap the wires temporarily to prevent accidental contact.

Note: If you don’t have an existing doorbell, you’ll need to run new wires from the transformer to the doorbell location. This may require drilling through walls and using fish tape—consider hiring an electrician if you’re not comfortable with this.

Step 2: Prepare the Mounting Surface

Clean the wall area and use a level to mark the mounting holes. Drill pilot holes and insert wall anchors. If your wall is brick or stucco, use masonry bits and appropriate anchors. For wood, self-tapping screws may suffice.

Step 3: Connect the Wires to the Aqara Doorbell

Strip about 1/2 inch of insulation from the ends of the two wires. The Aqara doorbell is non-polarized, meaning the wires can be connected in either direction. However, for consistency, connect the wire from the transformer to the terminal labeled “Trans” and the wire to the chime to the terminal labeled “Front” (if your chime has labeled terminals).

Secure the connections with the provided screws or spring clamps. Double-check that no bare wire is exposed and that the connections are tight.

Step 4: Mount the Doorbell

Attach the mounting bracket to the wall using the screws and anchors. Then, snap the Aqara doorbell into the bracket. Use the included security screw (usually a small Torx or hex screw) to lock it in place and prevent theft.

Apply a thin bead of clear silicone sealant around the edges of the doorbell to create a weatherproof seal. Avoid sealing the speaker or microphone holes.

Step 5: Restore Power and Test

Turn the power back on at the main panel. Wait about 30 seconds for the doorbell to power up. You should see a blinking LED light, indicating it’s ready for setup. Press the button—if you hear a chime inside, the wiring is correct.

Step 6: Connect to Wi-Fi via the Aqara Home App

Download the Aqara Home app (iOS/Android). Open the app, create an account, and tap “Add Device.” Scan the QR code on the doorbell’s back or in the manual. Follow the prompts to connect to your 2.4 GHz Wi-Fi network. The app will guide you through firmware updates and chime pairing.

Tip: If the connection fails, reset the doorbell by holding the setup button for 10 seconds and try again. Ensure your phone is connected to the same Wi-Fi network during setup.
