node-urtsi

A JavaScript interface for the Somfy Universal RTS Interface (URTSI).

This package was tested using the following:

• Raspberry Pi (with Raspbian)
• USB-to-DB9 Serial Adapter
• DB9-to-RJ45 Adapter (with Cat 6)
• Somfy URTSI II

Example

The URTSI class is instantiated with a path to the serial port (e.g. /dev/ttyUSB0 or /dev/ttyAMA0).

The URTSI class a few methods that return one or a group of the 16 channels.

Each channel or group of channels has the up(), down(), and stop() methods.

const urtsi = new URTSI('/dev/ttyUSB0');

// Open shades on the first channel.
const channel = urtsi.getChannel(1);
channel.up();

// Get an array of all 16 channels.
const channels = urtsi.getChannels();

// Close shades on the even channels.
const evenChannels = urtsi.getChannels([2, 4, 6, 8, 10, 12, 14, 16]);
evenChannels.map(channel => channel.down());

// Stop (or go to favorite position for) a group of channels.
const channelGroup = urtsi.getChannelGroup([1, 2, 3]);
channelGroup.stop();

Each command returns a promise:

urtsi.getChannelGroup().stop().then(() => {
  console.log('All shades are going to their favorite positions!');
});
