Emanuele has informed us of a new open source project known as OpenduinoGSM. This is a standalone wireless remote control board which communicates via GSM.
With OpenduinoGSM you have the option of using the Arduino development environment, so anyone, even those who are unfamiliar electronics and circuits, can try to realize the automation they want by writing simple code in C ++ or by using one of the many open source projects published and modifying it according to their needs.
For advanced users, the OpenduinoGSM also has a JTAG interface for use with AVR Studio.
Their first project is a GSM gate opener to control an automated gate. When the device receives a call from one of the numbers in the SIM phonebook, the OpenduinoGSM relay closes the contact for 3 seconds, activating the button that controls the opening of the gate. This project saves money by avoiding the need for a separate remote control other than a cell phone for the gate (or other connected device of your choice), and even the call is free, since after receiving the call the device only reads the caller ID and hangs up without answering thus avoiding consuming phone units!
