Does Light Switch H2 EU support both no-neutral and with neutral wiring?
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.
How to install the Light Switch H2 EU?
Taking Light Switch H2 EU (2-buttons, 1-channel) version as an example:
- Before installation, please remove the button, then unscrew to disassemble the switching unit, frame, and power unit for easier wiring and frame switching.
- Loosen the screws on the power terminal.
- 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.
- 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.
- 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.
How to reset Light Switch H2 EU?
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.
How to reset to factory settings?
Press any button 10 times continuously, then the blue indicator light starts flashing, meaning it’s in networking mode.
How can I distinguish between a live wire and a load wire?
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.
How to install it with a multi-gang plate?
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).
Will incorrect wiring cause a short circuit?
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.
- 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.
- 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.
