SmartWise Rain Sensor – eWeLink, Zigbee 3.0

The Smartwise MS1 Zigbee Rain Sensor is designed for smart scenes and smart home automations such as intelligent control of motorized roof windows, blinds, awnings, or irrigation systems. The sensor sends instant notifications via the eWeLink, SmartThings, or other compatible platforms, allowing you to remotely monitor current weather and rainfall conditions.

The sensor uses Zigbee communication technology, ensuring energy-efficient operation and a stable wireless connection. A Zigbee gateway or hub is required for operation, such as a SONOFF Zigbee Bridge, eWeLink or Tuya compatible gateway, another supported Zigbee hub, or Home Assistant. The sensor can be integrated into various automation scenarios, enabling automatic window closing, irrigation shutdown, or warning activation when rain is detected.

The IP66-rated housing makes it suitable for outdoor use, providing protection against rain and harsh weather conditions. Its special UV-resistant design ensures longer service life in outdoor installations. Thanks to its compact size, it can easily be installed on balconies, roofs, near windows, or even around gutters.

The highly sensitive detection surface allows the sensor to detect even small amounts of moisture. The eWeLink application provides event history and automation features, making the system easy to integrate into complex smart home environments. It is also fully compatible with Zigbee2MQTT.

About the eWeLink Ecosystem

eWeLink is one of the most popular smart home platforms, bringing together Wi-Fi, Zigbee, and Bluetooth devices from multiple manufacturers into a single application. The platform is especially well-known for SONOFF devices, but it also supports products from many other compatible brands.

The eWeLink platform enables users to create automations, schedules, scenes, and remote control functions while integrating with platforms such as Amazon Alexa, Google Home, and Apple HomeKit. Users can easily build complex automations by connecting various sensors and controllers together.

Thanks to their energy-efficient operation and stable mesh networking communication, Zigbee-based eWeLink devices are ideal for building reliable smart home systems.
