Description:

This driver interfaces with the Somfy RTS Universal interface. This interface allows for up to five channels of control of Somfy shades, blinds or awnings via RS-232.

The device only supports one-way commands; there is no way to query the current open/close state of a window covering. The device itself only allows commands to be received once every 1.5 seconds, so the driver will automatically queue commands and feed them to the controller at an appropriate rate.

Note that this device has a different protocol from the Multi-Link RS-232 multi-channel interface, which is a similar product from Somfy.

Quirks and Limitations:

None at this time.

Connection Details

This device uses an RS-232 connection, 9600 baud, 8 data bits, no parity and one stop bit. The device does not support any other communication settings, so the driver does not allow this to be configured.

Driver Fields

This section lists the fields that the driver makes available, their types, minimum and maximum values, etc...

Name	Type	R/W	Description/Limits
Command	String	W	Sends an command to operate the shade. Commands are two character values containing an action and a channel number. Actions are U, D and S for up, down and stop respectively. The channel is identified as a number 1 through 5. For example, the command U1 would send the up command to channel five. Multiple commands can be sent at one time, for example 'U1 U2 U3 D4' would send up commands to channels one through three, and the down command to channel four.
