Aqara Light Switch H2 US(4 Buttons, 3 Channel) WS-K04E

The Aqara Light Switch H2 US (4 Buttons, 3 Channel) (Model: WS-K04E) is a versatile smart wall switch that uses Thread and Zigbee protocols to control up to three independent lighting circuits and an additional scene control button. It is compatible with both neutral and no-neutral wiring, offering flexibility for various home installations.

Key Features:

• Connectivity Protocols: Supports both Zigbee 3.0 and Matter over Thread. This allows integration into a wide range of platforms, with Zigbee mode unlocking full Aqara Home features and Thread enabling native Matter compatibility.
• Wiring Flexibility: It is a 2-in-1 switch compatible with both neutral wire and no-neutral wire installations. Connecting with a neutral wire enables advanced features like power monitoring and overload protection.
• Decoupled Switch Mode: A key feature allowing any of the four buttons to be configured to trigger scenes or automations rather than controlling the physical relay. This provides a total of four potential wireless switches for complex smart home setups.
• Compatibility: Works with major smart home platforms, including Apple HomeKit, Amazon Alexa, Google Assistant, and SmartThings. An Aqara hub is recommended for access to all features within the Aqara Home app.
• Power Monitoring: When installed with a neutral wire, the switch can provide detailed real-time and historical power consumption reports in the Aqara Home app, helping to optimize energy use.
• Safety Features: Includes built-in overheat and overload protection mechanisms that automatically shut off the circuit in unsafe conditions (requires neutral wire installation).
• Electrical Rating (US): 120 VAC, 60 Hz, Max 10 A (Resistive Load).
• Dimensions: The product dimensions are approximately 119 x 74 x 42 mm (4.69 x 2.91 x 1.65 inches).
• Power-Off Memory: This feature ensures that connected appliances return to their last state (on or off) after a power outage, which can be customized in the Aqara Home app.
