Aqara H2 EU rotary light switch Grey — rotary control, BLE, 86×86×55.5 mm

The Aqara Light Switch H2 is a smart wall dimmer that supports both Thread and Zigbee protocols, offers installation options for homes with or without a neutral wire, monitors power consumption, and enables customizable automation. Control lighting via voice assistants, the Aqara Home app, or scheduled scenes. The device fits standard 55 mm frames and works with popular third-party frame systems.

Advantages

The dual-protocol design lets you choose Thread mode for direct integration with Matter-compatible ecosystems without an Aqara hub, or Zigbee mode to access Aqara-specific features and compatibility with classic Aqara Zigbee hubs. The 2-in-1 neutral design simplifies installation in homes lacking a neutral wire while providing additional functions—such as overload protection and power monitoring—when a neutral is available. The multifunctional dial acts as both on/off control and a smooth dimmer (1%–100%), and power monitoring in the Aqara Home app delivers daily, weekly, and monthly consumption data for energy management.

How to use

Install the switch in a standard 55 mm frame following local electrical regulations; choose the neutral or no-neutral wiring option based on your home’s wiring. Select Thread mode to connect directly to a Matter-enabled ecosystem or choose Zigbee mode to pair with Aqara Zigbee hubs and access Aqara-specific settings. Press the dial to turn lights on or off and rotate it to set brightness between 1% and 100%. Configure power monitoring, brightness limits, and automation rules in the Aqara Home app once the switch is paired.

Recommendations

For homes without a neutral wire, use the no-neutral installation option for easier setup. If a neutral is available, install using the neutral connection to enable power monitoring and overload protection. When using low-power LED lamps, set a minimum brightness limit in Zigbee mode to avoid flicker and ensure stable dimming performance.
