Aqara Light Switch H2

The default protocol is Thread. Note: Factory reset will not change the current protocol.

After restoring factory settings, check the LED indicator light to identify current protocol during device adding:

Blue blinking: Thread protocol

Purple blinking: Zigbee protocol

Red: Adding Timeout

1. Install the Aqara Home app, and enable Wi-Fi and Bluetooth.
2. Reset the device to factory settings (press any button 10 times continuously) to enter network setup (first-time device adding will automatically enter networking), which shows slow-blinking indicator.
3. In the Aqara Home app, tap Add Accessory, scan the Matter code on the button, select Zigbee under Switch Protocol page. Proceed following the app’s instruction.

1. Install the Aqara Home app, and enable Wi-Fi and Bluetooth.
2. Reset the device to factory settings (press any button 10 times continuously), then enter network setup.
3. In the Aqara Home app, tap Add Accessory, keep the phone close to the device, and light switch H2 EU will show in the app’s discovery section (at the top left). Tap the icon and select Thread under Switch Protocol page. Proceed following the app’s instruction.

Yes. Light Switch H2 EU supports both no-neutral and with-neutral wiring, regardless of your home wiring setup. It can be installed easily with no worries about compatibility.

Taking Light Switch H2 EU (2-buttons, 1-channel) version as an example:

1. Before installation, please remove the button, then unscrew to disassemble the switching unit, frame, and power unit for easier wiring and frame switching.
2. Loosen the screws on the power terminal.
3. Connect the live wire to the L terminal, the neutral wire to the N terminal (if the household wiring has one), and the load (light) wire to the L1 terminal.
4. Mount the power unit to the wall junction box with the attached screws and mount the frame, switching unit, and secure with the provided screws. Last snap on the button to finish.
5. Turn on main power at the circuit breaker, and test the switch by pressing the button. If the light can be controlled normally, the switch is working properly.

When not added to network, it will enter networking mode (blue indicator light blinks) when first powered on.

After adding, to reset the device, you need to:

Double-press any upper button, then press and hold it for 5 seconds until the blue indicator light starts blinking. This indicates that the device is in networking mode. Note that lower (wireless) button cannot be used for resetting.

Press any button 10 times continuously, then the blue indicator light starts flashing, meaning it’s in networking mode.

Typically, the live wire is red, the neutral wire is black or blue, and the load wire for lighting fixtures is green or yellow. It is recommended to have a professional electrician perform a test with specialized tools before installation.

For a perfectly aligned multi-gang setup, we recommend using the Aqara Switch Frame H2 EU (coming soon). This frame will allow for a clean, coordinated installation alongside compatible devices like the Wall Outlet H2 EU and the Dimmer Switch H2 EU (coming soon).

If the wiring is incorrect, the wall switch may fail to operate or even short-circuit, potentially causing damage. Be sure to follow the wiring instructions carefully or consult a professional electrician for installation.

1. if the neutral and live lines are reversed, the switch may still work, but turning it off leaves the live line active at the fixture, creating a shock hazard.
2.  if the light load (L1) is misconnected to the L or N terminal, there won’t be a short circuit, but the switch won’t respond until correctly connected.

To use the device with a particular Matter ecosystem (Thread Mode), a Matter Controller of this ecosystem and a Thread Border Router are required.

1. Double-press any button, then press and hold it for 5 seconds until the blue indicator light starts blinking. This indicates that the device is in networking mode.
2. Open the app that supports Matter, scan the Matter code on the manual or product, or enter the setup code to add the device to the app.
3. Proceed following the app’s instruction.

To use the device in Aqara Home (Thread Mode), an Aqara Hub with border router function (for example, Hub M3) is required:

1. Double-press any button, then press and hold it for 5 seconds until the blue indicator light starts blinking. This indicates that the device is in networking mode.
2. In the Aqara Home app, tap Add Accessory, choose light switch H2 EU. Scan the Matter code on the manual or product, or enter the setup code to add the device to the app. Select Thread under Switch Protocol page.
3. Proceed following the app’s instruction.

To use the device in Aqara Home (Zigbee Mode), an Aqara Zigbee Hub is required:

1. Double-press any button, then press and hold it for 5 seconds until the blue indicator light starts blinking. This indicates that the device is in networking mode.
2. In the Aqara Home app, tap Add Accessory, keep the phone close to the device, and light switch H2 EU will show in the app’s discovery section (at the top left). Tap the icon and select Zigbee under Switch Protocol page.
3. Proceed following the app’s instruction.

In the case where there is one wall separating the Light Switch H2 EU from the hub/border router, the communication distance can reach 7-10 meters. However, if there are multiple walls in between, it is recommended to position the devices as close to each other as possible for optimal communication.

Light Switch H2 EU does not support smart lights (including but not limited to dimmable, mode-adjustable, color-changing, gradient lights, or lights with built-in controllers, LED strips). Additionally, neither with-neutral nor no-neutral wiring supports high-power devices like bathroom heaters.

When connected to both neutral wire and live wire: no minimum load requirement.

When only connected to live wire: Minimums are 3W for energy-saving bulbs, 5W for LEDs, or 16W for fluorescent bulbs. Lower-quality lights may still flicker or cause issues. Please choose fixtures carefully.

Note: If using an old-style tube lamp with a starter, please replace it with an electronic starter.

Dimensions: 85.8*86*45 mm, in-wall depth of 30mm.

YES but only in with-neutral wiring, and light wattage shall be aligned with device load requirement.

① If you want to wire it to Aqara smart light  

Requirements: Zigbee mode (Aqara Zigbee hub), with-neutral wiring >> use MARS tech-Smart Load

② If you want to wire it to third-party ecosystem’s smart light

Requirements: Zigbee mode (Aqara Zigbee hub), with-neutral wiring, Relay Lock on/Decouple Switch Mode (Convert to wireless switch) >> use wireless switch exposed to Matter function to control 3rd party smart light
