The AQARA Smart Wall Switch H1 (No Neutral, Single Rocker) model WS-EUK01 is an innovative switch designed to make your home lighting systems smart, without requiring a neutral wire. Operating with the Zigbee 3.0 wireless communication protocol, this product, when paired with a compatible Aqara hub, offers remote control, scheduling, and the ability to create automation scenarios with other smart devices via the Aqara Home app. Its sleek and compact design (85.8 x 86 x 37.55 mm) fits any home decor, while the single rocker structure makes it very practical to use. Technically, it features a wide operating voltage range of 100-250V AC and a maximum resistive load capacity of 8A, allowing it to control even high-power lighting seamlessly. Not requiring a neutral wire greatly simplifies installation, especially in older buildings, while a typical minimum power consumption of 3W ensures energy efficiency. Thanks to the Zigbee 3.0 protocol, the switch provides a reliable and low-latency connection, operating stably at temperatures between 0°C and 40°C and humidity levels of 0-95% (non-condensing). As a use case, this switch is ideal for replacing existing single-pole switches in areas such as living rooms, bedrooms, or hallways. After installation, you can turn your lights on/off remotely via the Aqara Home app, set automatic timers based on sunrise/sunset, or create integrated automations with other smart devices like door sensors. Additionally, the indicator light on the switch allows you to monitor network connection status and possible overload warnings in real time.
