About the Crestron CI-SOMFY-RTS
This interface sits between a Crestron control system and Somfy RTS equipment, so that shades and drapery driven by Somfy RTS motors and receivers can be operated from the Crestron system. Crestron lists it among its third-party shade and drapery controllers, and describes it as an RS485 transmitter.
Each CI-SOMFY-RTS can control up to 16 groups of Somfy RTS motors and receivers. Before ordering a replacement or planning an extension, make a list of the Somfy RTS motors and receivers on site and how they are grouped, so the system stays within that limit.

Questions about the Crestron CI-SOMFY-RTS
What is the Crestron CI-SOMFY-RTS?
It is an RS485 Somfy RTS interface. Crestron describes it as an RS485 transmitter that acts as a motor controller, allowing a Crestron control system to manage Somfy RTS applications such as third-party shades and drapery.
How many Somfy RTS motors can the CI-SOMFY-RTS control?
It can control up to 16 groups of Somfy RTS motors and receivers. Check how the motors and receivers on site are grouped before ordering, so that the number of groups stays within what one interface supports.
What does the interface connect to?
On one side it works with a Crestron control system, and on the other it controls Somfy RTS motors and receivers. Crestron describes it as an RS485 transmitter and lists it among its third-party shade and drapery controllers.
Does the CI-SOMFY-RTS work with Somfy RTS receivers as well as motors?
Yes. Crestron states that it can control up to 16 groups of Somfy RTS motors and receivers, so both types of Somfy RTS device can be managed from the Crestron control system through this interface.
What should I check when replacing one?
Check the part number on the existing unit and count the Somfy RTS groups it controls, since one interface handles up to 16 groups of motors and receivers. Matching the existing model keeps the replacement consistent with the rest of the system.
How much is the Crestron CI-SOMFY-RTS?
Crestron asks its dealers to give the price of the CI-SOMFY-RTS directly rather than publish it online. Add it to your quote list and we will send you a written quote, with delivery, and installation and programming if you need them.
Can 1Install supply, install and programme the CI-SOMFY-RTS?
Yes. 1Install is an authorised Crestron Elite Partner with offices in Skerries, Co. Dublin and Cork. We can supply the CI-SOMFY-RTS on its own, or install, set up and programme it as part of your system. Installation visits are €440 for 4 hours or €880 for a full day, plus VAT and travel.
Does the CI-SOMFY-RTS come with a warranty?
Yes. Everything we supply is new, genuine Crestron with Crestron's standard warranty. If the CI-SOMFY-RTS develops a fault, contact us and we will handle the claim with Crestron. If we installed it, our workmanship is guaranteed for the lifetime of the system.
Is the CI-SOMFY-RTS in stock?
We order Crestron for each quote, so availability depends on Crestron's stock at the time. We check it before we quote and put the expected delivery date on your quote, so you know where you stand before you pay.
Can I buy the CI-SOMFY-RTS without installation?
Yes. We supply Crestron to end users, with or without installation. Like most Crestron devices of this type, it needs setting up or programming before it works in a system, and we can quote for that too.
