Somfy has fully integrated Zigbee 3.0 into its ecosystem, moving beyond its traditional proprietary protocols (RTS and io-homecontrol) to offer a more interoperable, two-way smart home experience. This allows for real-time feedback on device status, such as precise blind position and battery levels, which is not possible with older RTS technology.
Radio Technology Somfy (RTS) is Somfys older proprietary wireless protocol used to control motorised blinds,. It uses a one-way signal to send a command to the motor, but the motor cannot send status updates back to the user.
Still widely used but now superceeded by the newer ZIGBEE WiFi protocol.
