  • The Somfy 1810872 Universal RTS Interface II can be used to communicate between home automation or other third party systems and Somfy's RTS Motors and controls. It is capable of individual or group control, and can be operated via infrared remote, RS-232 and RS-485 serial communication. Once an input is activated, an RTS radio command is sent to the automated window treatment. This unit features 16 channels of Radio Technology Somfy (RTS) Control.

    The operation of the Universal RTS Interface is very similar to the Telis 4 Remote Control but there are now 16 channels available for programming. Each Channel can handle one or many RTS motors. You can have the kitchen on one channel, the living room on another, isolate mini groups and control all shades at once. With 16 channels of control the configurations are nearly limitless. All shades or motors assigned to one specific channel will operate simultaneously. The universal RTS interface controls Up, Down, Stop and customer preferred location commands for Somfy RTS motors.

    Please Note: The RS232 to RTS interface can not program the limit points on Somfy RTS motors. You will need a Telis Remote or similar RTS controller to program the shade motors. This interface simply provides the ability to communicate up/down/and stop commands for 16 RTS channels.

    Simple, works well, but does NOT come with any cables to hook it up to anything. Not a big deal, but at this price you think they would throw in a cheap rs232 cable or something...

    Michel from CALGARY, AB:

    How did you integate this on the Insteon network?
    Any help appreciated!
    Could I also use the Somfy motors with RS485 connectivity
    for the integration with Insteon?

    Very good product. Linked via the GCIP2SL to the insteon network. Hunter Douglas shades operate flawlessly.
