Understanding Your Aqara Doorbell and Compatibility

What Model Are You Installing?

Before you begin wiring, it’s essential to confirm which Aqara Doorbell model you’re working with. The most common models that require wiring include:

• Aqara Video Doorbell G2H Pro – Designed for Apple HomeKit Secure Video, supports 1080p HD, night vision, and two-way audio.
• Aqara Doorbell G4 – A newer model with enhanced AI detection, local storage, and support for both 2.4GHz and 5GHz Wi-Fi.

Both models are intended for hardwired installation, which means they draw power directly from your home’s electrical system via the existing doorbell circuit. This eliminates the need for batteries and ensures consistent operation, especially during extreme weather conditions.

Checking Compatibility with Your Home Setup

Not every home is immediately ready for a smart doorbell. To wire Aqara Doorbell successfully, you need to verify a few key components:

• Existing Doorbell System: Most homes have a low-voltage doorbell transformer (typically 8–24V AC) connected to a chime and a push button. The Aqara Doorbell is compatible with this standard setup.
• Transformer Voltage: Use a multimeter to check the output voltage at the doorbell terminals. Aqara recommends between 8V and 24V AC. If your transformer is 16V or 24V, you’re in good shape. Lower than 8V may cause instability.
• Wi-Fi Signal Strength: The doorbell must be within range of your Wi-Fi router. Aqara models support 2.4GHz and 5GHz bands (G4), but 5GHz may require a closer proximity to the router. Use a Wi-Fi analyzer app to test signal strength at your door.
• Apple HomeKit or Aqara App Access: If you’re using the G2H Pro, you’ll need an Apple Home Hub (HomePod, Apple TV, or iPad) for full functionality. The G4 works with both Apple HomeKit and the Aqara app.

Pro Tip: If your existing doorbell is battery-powered or doesn’t have a transformer, you’ll need to install a compatible low-voltage transformer (available at hardware stores) before wiring the Aqara Doorbell. This is a common step for older homes or apartments.

Tools and Materials You’ll Need

Essential Tools for a Smooth Installation

Having the right tools on hand makes the wiring process faster and safer. Here’s what you’ll need:

• Multimeter – To test voltage at the doorbell terminals and ensure the circuit is live or dead as needed.
• Screwdrivers – Both Phillips and flathead, preferably insulated for safety.
• Wire strippers – For preparing the existing doorbell wires (if they need trimming).
• Drill and wall anchors – If you’re mounting the doorbell on brick, stucco, or concrete.
• Level – To ensure the doorbell is perfectly aligned.
• Smartphone or tablet – To download the Aqara or Apple Home app and follow setup instructions.
• Electrical tape or wire nuts – For securing wire connections if needed.

Materials Included with the Aqara Doorbell

Most Aqara doorbell kits come with the following:

• Video doorbell unit
• Mounting bracket and screws
• Wire extension terminals (for connecting to existing doorbell wires)
• User manual and QR code for app setup
• Optional: Chime connector (for use with mechanical chimes)

Note: If you’re replacing an old doorbell, keep the existing wires intact. You’ll be connecting the Aqara Doorbell directly to these wires using the provided terminal block.

Optional but Recommended Add-ons

• Smart Chime – Aqara offers a wireless chime (like the Aqara Hub M1S) that pairs with the doorbell. Useful if your existing chime is outdated or you want indoor audio alerts.
• Ethernet Adapter – For the G4 model, a PoE (Power over Ethernet) adapter can provide a more stable connection than Wi-Fi.
• Weatherproof silicone sealant – To protect the wiring and mounting area from moisture, especially in rainy climates.

Example: John, a homeowner in Seattle, used silicone sealant around the mounting bracket after wiring his Aqara Doorbell G4. This prevented water ingress during winter storms and ensured the unit operated reliably for over a year.

Step-by-Step Wiring Process

Step 1: Turn Off the Power

Safety first! Before touching any wires, locate your home’s electrical panel and turn off the circuit that powers your doorbell. This is usually labeled “Doorbell,” “Front Porch,” or “Chime.” If you’re unsure, turn off the main breaker temporarily. Use a multimeter to test the wires at the doorbell location to confirm there’s no voltage.

Warning: Never assume the circuit is off. Always test with a multimeter. A false reading could lead to electric shock or damage to the doorbell.

Step 2: Remove the Old Doorbell (If Present)

Unscrew the existing doorbell button from the wall. Gently pull it away to expose the two wires connected to the terminals. Take a photo of the wiring for reference. Loosen the terminal screws and disconnect the wires. Label them if necessary (e.g., “Left Wire,” “Right Wire”).

Tip: If the wires are too short or damaged, use the wire extension terminals provided with the Aqara kit. Strip about 1/4 inch of insulation and insert into the terminal block.

Step 3: Prepare the Mounting Area

Clean the surface and use the mounting bracket as a template to mark screw holes. Drill pilot holes and insert wall anchors if needed. Use a level to ensure the bracket is straight. Secure the bracket with screws. Some models allow you to snap the doorbell directly into the bracket; others require a secondary plate.

Step 4: Connect the Wires to the Aqara Doorbell

Take the two doorbell wires and insert them into the terminal block on the back of the Aqara Doorbell (or the mounting bracket). The terminals are typically labeled “L” and “N” or “+” and “-”, but polarity does not matter for low-voltage AC circuits. Tighten the screws to secure the wires. If using extension terminals, connect the existing wires to the extension first, then attach the extension to the doorbell.

Example: Sarah in Austin had 18-gauge stranded wires from her old doorbell. She used the extension terminals to connect them to the Aqara G2H Pro, which has screw terminals designed for solid-core wires. The connection held securely after tightening.

Step 5: Mount the Doorbell and Restore Power

Snap the Aqara Doorbell into the mounting bracket. Ensure it’s snug and aligned. Turn the power back on at the electrical panel. Wait 30–60 seconds for the doorbell to boot up. You should see LED indicators (usually blue or white) on the front.

Step 6: Connect to Wi-Fi and Complete Setup

Download the Aqara app (or open Apple Home if using HomeKit). Follow the on-screen instructions to add the doorbell. You’ll need to scan the QR code on the device or enter the setup code. Connect to your Wi-Fi network (2.4GHz recommended for reliability). The app will guide you through naming the device, setting up motion zones, and enabling notifications.

Pro Tip: For the G4 model, use the Aqara app to enable AI detection (e.g., person, package, vehicle) and set up automations (e.g., turn on porch light when motion is detected).

Troubleshooting Common Wiring and Setup Issues

Doorbell Won’t Power On

If the LED doesn’t light up after restoring power, check the following:

• Verify voltage – Use a multimeter to confirm 8–24V AC at the terminals.
• Check wire connections – Loose or reversed wires can prevent power flow. Re-tighten and ensure no bare wire is touching the wall.
• Transformer output – If voltage is below 8V, replace the transformer. A 16V/30VA transformer is ideal.
• Fuse or breaker – Some doorbell circuits have inline fuses. Check for continuity with a multimeter.

Wi-Fi Connection Problems

Smart doorbells rely on stable internet. Common fixes include:

• Move closer to the router – If the signal is weak, consider a Wi-Fi extender or mesh system.
• Switch to 2.4GHz – The 5GHz band has faster speeds but shorter range and poorer wall penetration.
• Restart the router – Sometimes a simple reboot resolves connectivity issues.
• Forget and re-add device – In the Aqara app, remove the doorbell and set it up again.

Example: Mark in Chicago had intermittent Wi-Fi drops. He installed a Google Nest Wifi point near the front door, which improved signal strength from -85 dBm to -62 dBm—well within the recommended range.

Chime Not Working

If your mechanical chime doesn’t ring, the issue may be with the chime’s compatibility or the Aqara’s chime mode settings. Aqara doorbells support two modes:

• Mechanical chime mode – For traditional doorbell chimes. Ensure the chime connector is properly installed.
• Digital chime mode – For use with Aqara’s wireless chime or smart speakers.

Go to the Aqara app > Device Settings > Chime Mode and select the appropriate option. Test by pressing the doorbell button.

App Not Recognizing the Doorbell

If the app fails to detect the device during setup:

• Ensure Bluetooth is enabled on your phone.
