Ondeis™ WireFree RTS Rain and Sun Sensor


The Rain Sensor is a solar-powered combined rain and sun sensor compatible with Radio Technology Somfy® motorized exterior products, including awnings, rolling shutters and screens. The Sensor is completely wireless and uses optical rain-sensing technology to measure rainfall and sends an RTS command when rainfall exceeds the user-selected threshold. The Sensor also utilizes a sun-level sensor that sends an RTS command when sunlight exceeds the user-selected threshold.


Comfort & Convenience

  • Automatically operates motorized applications based on selected weather conditions with 6 available modes (for example: retracts an awning when it rains, extends it when it is sunny,  closes the screens when it is sunny, etc… )

Protects the Awning

  • Heavy rain can cause damage. The rain sensor automatically retracts the awning based on the selected rain threshold.

Energy Savings

  • Energy cost reduction and automatic protection from damaging UV rays.
  • Optical Rain and Sun Sensor  
    • Senses moisture from heavy fog to a downpour. Heavy rain can cause damage to an extended awning. Provides protection from the elements. Senses brightness levels from .5 klux to 50 klux.  Protects from harmful UV rays and provides comfort and energy savings.

    Solar Powered

    • Provides a maintenance-free and green solution.  Totally wireless, battery-free installation. No electrician – really easy.

    Flexible and Easy to Install
