If the location of the mobile communication device matches the location associated with the automation system, the mobile communication device transmits a command to the automation system. According to another method, a mobile communication device determines if it has entered wireless communication range of an automation system and determines if it has exited wireless communication range of an automation system. In response to determining if the mobile communication device has entered wireless communication range of an automation system, the mobile communication device transmits a first command from to the automation system. In response to determining if the mobile communication device has exited wireless communication range of an automation system, mobile communication device transmits a second command to the automation system.
