Key Features
1. Thread and Zigbee Support
The Aqara Light Switch H2 US offers built-in support for both Thread and Zigbee protocols, giving users flexibility in choosing the best communication method for their setup:
- Thread Protocol: Enjoy native Matter compatibility for seamless platform interoperability, ensuring the switch integrates smoothly with other Matter-enabled devices.
- Zigbee Protocol: Take advantage of Aqara's robust ecosystem, which includes additional features like power monitoring, configurable LED indicators, and button decoupling, making it more versatile than many competing options.
2. Neutral and Non-Neutral Wiring Support
One of the standout features of the H2 US is its 2-in-1 neutral wire compatibility, allowing it to work in homes with or without neutral wires. This simplifies installation for DIY users and makes the switch suitable for modern and older houses.
- With Neutral Wire: Users can access enhanced features like overload protection, power monitoring, and a customizable LED indicator.
- Without Neutral Wire: Enjoy core smart switch functionality without worrying about rewiring your home.
3. Flexible 3-Way Control
The 2 Buttons, 1 Channel version supports single-pole and 3-way switch configurations, making it easy to replace traditional 3-way switches. This ensures flexible control of lights from two locations, a common requirement in hallways or staircases.
4. Additional Button for Smart Home Control
Each H2 US switch includes up to 4 buttons that can act as wireless triggers for smart home devices or scenes. These buttons can be configured to control functions like:
- Unlocking a door.
- Opening curtains.
- Arming a security system.
- Activating a customized home scene.
The Aqara Home app also allows for Custom Press Mode, enabling separate automations for single-, double-, and long-press actions.
5. Independent Light Circuit Control
The electrical buttons can be decoupled from light circuits through the Aqara Home app when using the Zigbee mode. This feature is handy for smart lighting systems, as it allows users to control smart lights without cutting off their power supply—a common issue with many smart switches.
6. Power-Off Memory
The switch's power-off memory ensures that wired lights return to their previous state after a power outage. Whether the lights stay on, off, or reverse to their previous state, this feature prevents unexpected disruptions, like lights turning on at night.
7. Power Consumption Monitoring
When connected with a neutral wire, the H2 US can monitor energy usage and provide detailed insights through the Aqara Home app. Users can analyze historical power consumption data to identify energy-saving opportunities and better manage electricity costs.
