    Brochure for the Somfy ZRTSI — the Z-Wave® to Radio Technology Somfy® Interface (Cat. No #1811265), a bridge controller that translates Z-Wave transmissions into motor commands for Somfy's full range of interior and exterior RTS motors.

    Overview

    The Z-Wave® to Radio Technology Somfy® Interface (ZRTSI) is a Z-Wave bridge controller that receives Z-Wave transmissions and converts them to motor commands for Somfy's full range of interior and exterior RTS motors. With intuitive menu-driven programming, the ZRTSI makes integrating RTS motorized products into Z-Wave-based automation systems easier than ever.

    The ZRTSI can be used to control up to 16 individual RTS motorized products, or 16 groups of RTS motorized products, within Z-Wave home automation systems.

    Z-Wave certification #ZC08-1308005

    Key Benefits

    • Addressability: Unique network address for control of individual motors.
    • Networkability: Communication via industry-standard RS-485 network.
    • Configurability: Individual or group control with customizable pre-set positions.
    • Flexibility: Simple to integrate with third-party automation systems via dry contact, IR, or RS-232/RS-485.
    • Expandability: Easily add ILT motors and accessories to meet changing application requirements.

    Integration with Somfy TaHomA®

    By incorporating a ZRTSI into Somfy's TaHomA home automation system, users can combine Somfy-powered motorized products with lighting and thermostat settings for a convenient, energy-efficient home control solution. In TaHomA's dashboard, users can easily access the "MY" position for any RTS motorized product.

    The ZRTSI bridges between a Z-Wave network (via a wireless router, Wi-Fi, or Ethernet) and Somfy RTS motorized products such as Sonesse 30 RTS and Tilt WireFree RTS shades/blinds, either directly or through a TaHomA controller or a third-party home automation system / third-party controller.
