A little more investigation reveals that the system is call-driven. You dial a number (that you of course can store in your contacts) and enter the six digit code to turn on the lights in your street. That way, even old landline phones that can send DTMF signals can be used to turn on the lights, but you still have to register that number online.
An added advantage of using "voice" rather than SMS is that voice calls either go through immediately or get refused, while SMS messages can be queued, delaying the lighting. ________________________________________________________________ Welcome to the Interaction Design Association (IxDA)!
