[Thread/Zigbee Support] The Dimmer Switch H2 EU supports Zigbee and Thread protocols for versatile connectivity. In Zigbee mode, you can access advanced features and Matter compatibility via a compatible hub (hub required). Thread mode allows direct integration with Matter-enabled ecosystems like Apple Home, Google Home, Alexa, SmartThings, and Home Assistant (a Matter Controller within the ecosystem and a Thread Border Router are required).
[2-in-1 Neutral] Whether your home has a neutral wire or not, the Dimmer Light Switch H2 is designed for hassle-free use. Its simple installation supports both no-neutral and with-neutral wiring setups, so you don’t need to worry about your home’s wiring configuration. For homes with neutral wiring, overload protection is enabled for added safety. The minimum mounting box depth is 40 mm, making installation more convenient.
[Multi-Functional Dial] Equipped with a built-in wireless switch, the Smart Light Switch H2 enables smooth dimming and on/off control, offering a 1–100% dimming range. Whether you prefer a soft ambient glow or full brightness, this dimmer ensures flicker-free transitions across the entire brightness spectrum (recommended for use in Zigbee mode).
[Wide Fixture Compatibility] The H2 EU supports a wide range of non-smart dimmable lighting fixtures, including Incandescent/Halogen (Max 350W) and dimmable CFL/LED/ELV (Max 200W). Minimum power requirements: 4W (when used via Matter with a compatible app) or 9W (via other methods). MLV is not supported. (Note: Can be wired to a smart light of compatible wattage under with-neutral wiring for on/off control). The H2 also provides power monitoring, which is best used in Zigbee mode.
[55 mm Frame Support] The dimensions of the H2 dimmer switch are 86 × 86 × 55.45 mm, with an in-wall depth of 34.6 mm. Its modular design fits all standard 55 mm switch module systems (55 mm × 55 mm). It also supports third-party multi-frames such as Gira System 55 and Merten M, offering excellent flexibility. Third-party solutions such as Zigbee2MQTT or similar USB dongles may not be officially supported, and full product functionality could be limited or unavailable.
