Thread/Zigbee Support
Includes Thread and Zigbee protocol support; Thread enables connection to Matter ecosystems*, while Zigbee mode** unlocks exclusive Aqara features. The switches remain compatible with classic Aqara Zigbee hubs while maintaining future-proof Matter support. Easily switch between protocols as needed.
**Aqara Zigbee hub required. Zigbee 2MQTT and comparable third-party USB dongles are not Aqara-supported. Full product functionality may be limited or unavailable.

3-Way (2-Way) Control
Designed for flexible use, the switch is compatible with single-pole or 3-Way (2-Way) wiring. It operates with or without a neutral wire. Replace your traditional 3-Way (2-Way) switches for smart control without losing the 3-Way (2-Way) function.
2-in-1 Neutral
This switch works with or without a neutral wire, offering easy installation. When connected with a neutral wire, it enables enhanced features with built-in overload protection and real-time power monitoring* for smarter energy management.

Power Monitoring
The Aqara Home app provides a clear view of your real-time and historic energy consumption for connected lights, with detailed data and visual charts available by day, week, month, or year. This allows you to track energy usage and gain valuable insights. Use this information to create energy-saving plans and automations for more sustainable energy use.
Power-Off Memory
This feature automatically restores your appliance's previous on/off state after power outages. Customize preferences to always on/off, or reverse settings for ultimate flexibility. Ensures seamless operation and energy efficiency.
Customized Wired & Wireless Buttons
Decoupled Switch Mode*
Decoupled Switch Mode disables the physical button's control of the relay, allowing it to be pressed exclusively for scenes and automations. This setup keeps the connected circuit unaffected by physical interaction, but it still can be controlled via app/automation/voice.
Relay Lock*
Set shutter positions for different scenes, times of day, or moods, all controllable within the app. Easily integrate them into automations for a smarter home experience.
Custom Press Mode*
** (2 Buttons, 2 Channels) version does not support custom press mode because all buttons are dedicated to controlling the channels.

Quick Two-Way Control
When configured, this switch (decoupled) enables two-way control of the light or wired load with another Aqara smart switch**
. Additionally, the indicator lights on both switches are synchronized for smooth operation.
** The associated button must correspond to the light/load wired to the controlled switch, and the controlled device must be an Aqara switch.
