CI-Somfy-RTS Crestron Home™ driver

It is recommended that you save a configuration or golden configuration before installing any driver.

You don’t strictly need it if you use a COM port that supports RS-485 (such as COM 1 on the CP4R). However, if you use any other COM port that doesn’t support RS-485 (like on an NVX), than you will need an adapter.

Currently, we were able to successfully test using this DTECH adapter from Amazon. On a CP4R, we noticed that if you want to use COM 1, you will first need to select another COM port (such as COM 2) during install and then switch to COM 1. If you use any COM port other then 1, than you don’t need to do this. If you encounter any other adapters that work, you may let us know at drivers@digitalautomation.us. We’ll update this post as we encounter other adapters that have been reported with success.

You can add shade controls to your Keypads by creating quick actions. You can add these quick actions to any room. Then chose to have them shown or not on the UIs by selecting and editing the property using the eye symbol next to the quick action.

Then you can reference the quick action on any keypad as shown in the next snapshot.

In order to control all or a group of shades at once, you will need to pair all the shades to a single channel. If for some reason it’s not possible to do this, than an alternative is to define a quick action and add the shades you want to control to the quick action. The disadvantage with this option is that the shades will move in a staggered manner.

On the RS232 side, from the processor, you connect tx from the processor to the rx on the adapter and rx on the processor side to tx on the adapter. Ground from the processor goes to ground on the adapter. On the RS485 side, you would wire the TX/RX+ from the adapter side, to the + on the Somfy transmitter and the TX/RX- from the adapter to the - on the Somfy transmitter. Although wiring RS485 ground is optional, it is recommended to connect ground from the adapter to ground on the device. The example image below shows how the wiring should look like between the adapter and the Somfy transmitter.

It is recommended that you contact Somfy tech support or consult with your shade installation contractor for full details. Briefly, Somfy provides the software (called RS485 Demo Tool) and a USB-to-RS485 cable. You connect the cable to your computer and connect the other end to your CI-Somfy-RTS transmitter (make sure your transmitter has power!). Use the Somfy OEM remote to job the shade into pairing mode. Than in the software, select your channel and than choose “Open Programming Mode” and that will pair the shade to your transmitter at your selected channel. In a future driver update, we will make the “Open Programming Mode” command available.

Yes, The CI-Somfy-RTS Crestron Home Driver allows the system to control multiple devices connected to multiple COM ports. Install a separate instance of the platform driver to each COM port.

Check the “Number of Rooms” field in the Installer Settings tab and the COM port configuration. Also CH OS4 has moved the folder to a dedicated “Managed Platforms” that appears at the top most menu level.
