Installing Your Aqara Smart Wall Switch H1 EU (With Neutral)

The Aqara Smart Wall Switch H1 EU (With Neutral) is a Zigbee-connected wall switch designed for European-style installations where a neutral wire is available in the switch box. Having a neutral wire provides more reliable operation and eliminates the minimum load requirement found in no-neutral versions. This guide covers the electrical installation and software setup.

What You Will Need

• Aqara Smart Wall Switch H1 EU (With Neutral)
• Aqara Hub (M2, M3, or Camera Hub G3) already set up on your network
• Aqara Home app installed on your smartphone (iOS or Android)
• Flathead and Phillips head screwdrivers
• Voltage tester or multimeter
• Wire strippers (if needed)

Important Safety Warning

Turn off the circuit breaker controlling the switch you are replacing before beginning any work. Use a voltage tester to confirm that no power is present at the switch box. If you are unfamiliar with electrical wiring, hire a qualified electrician to perform the installation.

Identifying Your Wires

The neutral-wire version of this switch requires three connections. Before removing your old switch, identify the wires in the switch box:

• Live wire (L) — The hot wire from your breaker panel, typically brown in EU wiring.
• Neutral wire (N) — The return wire, typically blue in EU wiring. This may be bundled together with other neutral wires in the back of the box.
• Load wire (L1/L2) — The wire going to your light fixture, which may vary in color.
• Ground wire — Green and yellow striped, connected to the ground terminal.

Removing the Existing Switch

1. With the breaker confirmed off, remove the existing switch's faceplate.
2. Unscrew the switch from the wall box and carefully pull it forward to expose the wiring.
3. Note which wires connect to which terminals. Take a photo for reference if needed.
4. Disconnect all wires from the old switch.

Wiring the Aqara Switch

1. Locate the terminals on the back of the Aqara switch: L (live), N (neutral), L1 (load 1), and if applicable, L2 (load 2 for the double-rocker version).
2. Connect the live wire to the L terminal.
3. Connect the neutral wire to the N terminal. If the neutral wires in the box are joined together, add a short pigtail wire from that bundle to the switch's N terminal.
4. Connect the load wire to the L1 terminal. For the double-rocker version, connect the second load wire to L2.
5. Connect the ground wire to the appropriate terminal.
6. Carefully push the wires into the box and mount the switch with the included screws.
7. Attach the faceplate.

Powering On and Pairing

1. Turn the circuit breaker back on. The switch's LED indicator should illuminate.
2. Open the Aqara Home app and tap the + icon.
3. Select Smart Wall Switch H1 EU (With Neutral) from the device list.
4. Choose the Aqara Hub you want to pair with.
5. Press and hold the switch button for 5 seconds until the LED begins flashing rapidly.
6. Wait for the app to discover and pair the switch. This usually takes 10 to 30 seconds.
7. Assign the switch to a room and name it appropriately.

Configuring the Switch

After pairing, customize the switch behavior in the Aqara Home app:

• Power-on state — Set the default state after a power outage: previous state, always on, or always off.
• LED indicator — Choose when the LED light is visible.
• Decoupled mode — Separate the physical button from the relay to use the button purely as a wireless trigger for automations while keeping the connected light in a fixed state.

Advantages of the Neutral-Wire Version

• No minimum load requirement — works reliably with any LED bulb, even those rated under 3W.
• No flickering issues when the light is turned off.
• More stable Zigbee connection since the switch receives consistent power through the neutral wire.
• The switch doubles as a Zigbee router, extending your mesh network's range.

Tips

• This switch is designed for the EU market and fits standard European round or square wall boxes. Verify your wall box dimensions before purchasing.
• Test both physical button operation and app control after installation.
• Check for firmware updates in the Aqara Home app after pairing to ensure you have the latest features and fixes.
