It is used for accumulation and storage of system data. The device determines the logical scheme of the system and allows authorized access to the system via the Internet. It also converts Ethernet into CAN bus and vice versa. DE-MG has a built-in IR receiver.The DE-MG can be controlled via cloud with a securely encrypted signal. The system history from all other devices and sensors is stored on the DE-MG for one year. Its plug and play feature means that it automatically detects and configures new Larnitech devices that are added to the system. A large and constantly updated database of ready-made scripts ensures that your home does everything your heart may desire. Get things going by telling your home what to do with the help of Siri, Alexa or Google Home. Get push notifications on your phone whenever the system has things to tell you and enjoy the ultimate control at your fingertips
