Cable without neutral conductor: you don't have to worry about the compatibility of your device. The Aqara Smart Light Switch H1 EU can be installed even if your existing wiring is not equipped with a neutral conductor. (Note: some features such as performance monitoring are not available and performance will be more limited.)

【SUPPORT ROUND WALL ENCLOSURE】The Aqara Smart Light Switch H1 EU is compatible with 86mm square wall housing and with round EU wall housings. (Note: not all double/double wall enclosures are comparable. Please check the product size before purchase.)

【Two-way switch configuration】 you can achieve more application areas by combining the Aqara Smart Light Switch H1 EU with other Aqara products. With the Aqara wireless remote switch H1, you can easily control the same lights from two or more places without additional wiring. (Note: An additional H1 wireless switch is required for two-way configuration.)

【Wireless Switch Function】 The Aqara Smart Light Switch H1 EU can be part of your smart home solution. By converting into the function of a wireless switch, the switch can be controlled by automations with the Aqara motion sensor or the wireless Aqara mini radio switch, for example, while the switch button controls other devices
