DATA HUB PLUS – 1870263


Improved Connectivity for Somfy Digital Network Systems

Adds 5 isolated device ports to an SDN Bus line. Isolated device ports support longer wire stubs beyond the 30 ft. of the standard Data Hub.


SDN 2.0 products are backed by a SDN 2.0 Certified Quality Promise which means these products have been designed to meet the highest standards for Somfy Digital Network system components and validated by Somfy engineers. Systems designed using SDN 2.0 certified products are easier to install, more reliable, and improve overall system performance.


Efficient Power and Data Distribution

  • Increase the number of devices or bus segments in a system.
  • Isolated data distribution is built into the products and offered stronger data delivery throughout the system.
  • Most innovative motor options are complimented with smart power and data distribution devices to improve the overall experience of digital Somfy motors.

Improved System Design

  • Add devices or segments to a system by choosing the best product in the design.
  • Expand the size of any system by allowing longer wiring lengths or connecting more devices.
  • Built in end of line notification provides automatic termination in system which ensures signal integrity.

Simplified Installation

  • Protect wired devices in case power, ground or data wires are not connectly properly.
  • Easily connect components together using the factory printed port labels and the common RJ45 connection ports.
  • System status LEDs monitor Bus power, SDN activity, SDN idle and end of line indication.

The Data Hub Plus is a Somfy Digital Network™ (SDN) bus distribution component which adds 5 isolated device ports to an SDN Bus line. The isolated device ports support longer wire stubs beyond the 30 ft. of the standard Data Hub. A wire stub is an extension of the bus segment which connects the bus line to the user interfaces, motors or integration devices. The wire stubs consist of any devices which split away from the main bus distribution line in a system. A connected device can include a keypad, Radio Technology Somfy® (RTS) receiver, motor or Somfy Connect™ product.
