Somfy offer two technologies here, radio controlled remote, and fully integrated home automation.

i) Radio Controlled (RTS)
Motors can be either 240 volt hard wired to the motor point, or battery operated
Tracks can have dual motors for long tracks, be curved or bent to accommodate around corners
The new technology Somfy Movelite 35 Battery will move up to 35 kg of curtaining from one motor
Somfy Movelite 35 Battery have a removable battery pack similar to a power pack hand tool, as a rule of thumb, recharging is required only once per 3 months, with a re-charge time of approximately 6 hours
“Somfy Conexoon” is a wifi device, allowing multiple Somfy RTS products to be controlled via mobile phone (or the Conexoon unit), rather than remote control units (like a TV remote). Standard remote controls are also available

ii) Switch Controlled (WT)
“Motors are 240 volt hard wired to the motor point, there is currently no battery option
Tracks can have dual motors for long tracks, be curved or bent to accommodate around corners
Each motor is wired back to the central “home automation” system, such as “Control 4” etc.
Switch motors are slightly less expensive than RTS options, as they do not require the radio control frequency data card inside the motor” 9Dual motor systems do require additional co-ordinating relays though)
