Aqara Smart Wall Switch H2 (Vertical)

Product Description:

Aqara Smart Wall Switch H2 (Vertical) is designed for ultimate compatibility and convenience, supporting both Zigbee and Matter over Thread protocols for seamless integration with third-party ecosystems. Effortlessly turn lights and other smart devices on or off or control them wirelessly with ease. No need to worry about compatibility with your home’s existing wiring—this switch supports both with-neutral and no-neutral setups. Available in 1 to 3-channel versions, it adapts to diverse control needs, making it the perfect choice for different scenarios.

Key Features:

● Thread/Zigbee Support

The device features dual protocol support. In Thread mode, no Aqara hub is required to connect to third-party Matter ecosystems [1], while Zigbee mode [2] unlocks exclusive Aqara features and ensures backward compatibility with Aqara Zigbee hubs. The flexible protocol switching [3] lets users enjoy Matter integration or Aqara's advanced functionalities based on their preference.

● Works With or Without Neutral Wire

Whether your home has a neutral wire or not, this switch is designed for hassle-free installation. It supports both no-neutral and with-neutral wiring setups, eliminating any concerns about your home's wiring configuration. For homes without a neutral wire, installation is straightforward, while homes with a neutral wire benefit from advanced features like overload protection and power monitoring [4] enhancing both safety and efficiency.

● Customise Buttons for More Wireless Control [5] [6]

Your buttons can go beyond simple on/off, they also can trigger scenes and automations you configure. Decouple or lock the relay to turn buttons into wireless triggers, then expand them with single, double, and long presses to trigger multiple devices with one button, one switch becomes a powerful controller for your entire smart home.

● Manage up to 3 Separate Lighting Circuits

Offers flexible control of up to 3 circuits with multifunctional buttons. Whether you need simple or advanced control, these buttons provide both relay and wireless control for managing multiple lighting circuits and smart home automations with ease.

● Power Monitoring [7]
The switch monitors the power consumption of connected wired devices and provides daily/weekly/monthly energy consumption reports in Aqara Home. Users can use these data reports to optimise their daily electricity usage or create energy-saving plans and automations to reduce consumption and increase sustainable energy use.
