Aqara - Dimmer Switch H2 EU (KD-R01D) White

Aqara Dimmer Switch H2 EU

A multi-function dimmer switch with a rotary dial designed for ultimate compatibility and convenience, supporting both Zigbee and Matter over Thread protocols for seamless integration with third-party ecosystems. It can work with or without a neutral wire. It is compatible with various lamps, including incandescent, halogen, dimmable LEDs and CFLs. Users can switch dimming modes according to load types to achieve optimal dimming and maintain stable operation of the equipment. Remote control, scheduling, power monitoring and other functions can be achieved through the application.

Highlights :

Thread/Zigbee Support : The device features dual protocol support. In Thread mode, no Aqara hub is required to connect to third-party Matter ecosystems①, while Zigbee mode② unlocks exclusive Aqara features and ensures backward compatibility with classic Aqara Zigbee hubs. The flexible protocol switching③lets users enjoy Matter integration or Aqara's advanced functionalities based on their preference.

2-in-1 Neutral for Hassle-free Installation : 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 monitoring④, enhancing both safety and efficiency.

• No neutral and with-neutral wiring setups
• No wiring modification required

Multi-Functional Dial : The multi-function dial has a built-in wireless switch. Users can turn it on and off by pressing the dial, and can also make a smooth transition from 1% to 100% by turning the dial to achieve precise dimming, so that the light in your home better matches your living environment. The default response time is 1.5 seconds⑤ and user can also set the customized response time④.

• Swtich on/off
• 1%-100% dimming
• customized respond time
• Dial sensitivity adjustment
• Adjustable on/off transition from 0-10s

Wide Light Compatibility : The dial switch offers wide light compatibility⑥, supporting incandescent, halogen, dimmable CFL/LED. Leading /Trailing Edge Dimming compatibility can easily match existing lamps, bring a stable dimming experience, ready for future lighting upgrades. The default mode is Trailing Edge Dimming, as all the compatible light types can work under this method.

• Wide light compatibility
• Incandescent
• Halogen
• Dimmable CFL/LED

55 mm Frame Support⑦ : Dimmer switch H2 EU fits seamlessly into all standard System 55 switch modular systems (55 mm x 55 mm) and supports popular third-party multi-gang frames like Gira System 55 and Merten M, making installation easy even without an electrician. Its standardized design ensures compatibility across EU markets, minimizing the need for custom fittings and simplifying integration into existing setups.

• Standard 55 switch modular systems
• Support third-party multi-gang frames
• Gira E2
• Gira 55
• Busch Balance SI
• Schneider MertenM
• JUNG A550
• Berker S.1

Power Consumption Monitoring⑧ : 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 optimize their daily electricity usage or create energy-saving plans and automations to reduce consumption and increase sustainable energy use.

• Monitors the power consumption of wired devices
• Output energy consumption reports
• Daily/weekly/ monthly data

Custom Brightness Limits : Users can set the dimming range in Aqara Home using Zigbee Mode to change the maximum and minimum brightness to keep the device running smoothly and prevent light flickering and power loss. Maximum brightness⑨ ensures that low-power lights work smoothly at maximum brightness without flickering or shutting down. Minimum brightness prevents lights from flickering, being unstable, or failing to turn on when set to low brightness levels. This feature helps users optimize the operation of their devices.

Disclaimers :

• ① To use the device with a particular Matter ecosystem, a Matter Controller of this ecosystem and a Thread Border Router are required.
• ② Aqara hub is required when using Zigbee mode.
• ③ To switch protocols, you need to factory reset the device.
• ④ This feature might be unavailable in some or all third-party Matter ecosystems, but is indeed supported by the device. To guarantee its functionality, we suggest using the Zigbee mode and connecting the device to an Aqara hub.
• ⑤ Transition setting can allow users to tailor how quickly or slowly your lights change from off to on, or vice versa, ensuring every lighting transition fits the mood and activity. With adjustable settings ranging from instant (0 seconds) to a deliberate fade (up to 10 seconds), you have the freedom to create the perfect atmosphere for every occasion. Upon switching on, lighting will increase from 0 to 100% in 1.5 seconds. This feature might be unavailable in some or all third-party Matter ecosystems, but is indeed supported by the device. To guarantee its functionality, we suggest using the Zigbee mode and connecting the device to an Aqara hub.
• ⑥ MLV is incompatible. Minimum Power: 4W (Aqara Home via Matter), 9W (other methods), general purpose. When only using a 4W light bulb in Aqara Home, please set the maximum brightness to 70%-75% to prevent flickering.
• ⑦ The dial control unit measures 55 × 55 mm without the frame, fitting perfectly into the Aqara Switch Frame H2 EU (our European standard 55 mm frame coming soon).
• ⑧ With-neutral wiring is required for power monitoring. This feature might be unavailable in some third-party Matter ecosystems, but is already supported by the device. To guarantee its functionality, we suggest using the Zigbee mode and connecting the device to an Aqara hub.
• ⑨ Please note: the feature might be unavailable in some or all third-party Matter ecosystems, but is already supported by the device. To guarantee this functionality, we suggest using the Zigbee mode and connecting the device to an Aqara hub. Maximum Brightness setting is only available in Zigbee mode.
