Dimmer Switch H2 US
A versatile smart dimmer that can be installed without a neutral wire. Features Matter over Thread & Zigbee with seamless, flicker-free lighting control.
Unmatched Flexibility & Future-Proof Control with Thread and Zigbee
Step into the future of the smart home. The H2 Dimmer supports both Thread and Zigbee protocols, giving you unparalleled choice. Use Thread for a direct, hub-free connection to your favorite Matter ecosystems like Apple Home, Google Home, and Amazon Alexa, enjoying lightning-fast, ultra-reliable local control. Or, use Zigbee to connect with an Aqara hub, unlocking exclusive features like advanced automations and energy monitoring while still maintaining full Matter compatibility. This dual-protocol approach ensures your smart home is not only powerful today but ready for whatever comes next.
End the #1 Installation Headache: Works With or Without a Neutral Wire
Stop worrying about your home's wiring. The number one challenge for upgrading to smart switches is the dreaded "no-neutral" wire issue. The Dimmer H2 solves this completely by supporting both with-neutral and no-neutral setups, making it compatible with almost any home in the US, new or old. This design eliminates the guesswork and frustration, making installation straightforward and hassle-free for everyone. When installed with a neutral wire, you unlock advanced features like overload protection and detailed power monitoring.
Finally, Silence: Quiet, Tactile & Perfectly Tuned Dimming
Tired of the loud CLICK from other smart switches? We designed the H2 Dimmer for peace and quiet. All buttons provide a satisfying, tactile feel without the disruptive clicking sound of traditional relays. The dedicated buttons for on/off and brightness give you intuitive control. Enjoy flawlessly smooth dimming, from a gentle, atmospheric glow to bright, functional light. Plus, with customizable transition speeds in the Aqara Home app, you can set your lights to fade in gracefully or turn on instantly, perfectly matching any mood or activity.
Eliminate Flickering and Buzzing Across All Your Bulbs
Get the perfect dimming experience you've always wanted. A common complaint with other dimmers is flickering or buzzing, especially with LED bulbs. The H2 Dimmer is engineered for extensive compatibility, supporting incandescent, halogen, and a wide array of dimmable LED and CFL bulbs. By supporting both forward and reverse phase dimming, it intelligently adapts to your specific lights, ensuring stable, silent, and flicker-free performance.
Your Lights, Your Way: Set Custom Dimming Limits
You are in complete control of your lighting range. Prevent the annoying flicker that happens when dimming low-power LEDs too low, or set a maximum brightness to create the perfect ambiance that's never overpowering. The "Minimum Brightness" setting ensures your lights never drop into a problematic range, while the "Maximum Brightness" setting can help extend bulb life and save energy. Once set, the switch will not go below or above these limits, guaranteeing a consistent and reliable experience every time.
Unlock Smart Energy Insights with Power Monitoring
Go beyond simple control and make your home smarter. When installed with a neutral wire, the Dimmer H2 tracks the energy consumption of your connected lights. Through the Aqara Home app, you can view easy-to-read daily, weekly, and monthly reports. Use these insights to identify energy-hungry fixtures and create powerful automations that reduce your electricity bill and build a more efficient home.
