The EFC-02 Mini controller, when connected to the WI-FI, gives the possibility to control all receivers of the EXTA FREE system from mobile devices. In addition to the function of "virtual" transmitters, the EFC-02 Mini controller has the ability to implement SCENES, TIME FUNCTIONS and view the state of sensors. Communication with the receivers of the system takes place on the radio route using the frequency of 868.32MHz. The controller connects to the Wi-Fi router using a LAN cable terminated with an RJ45 plug. Configuration and control is carried out from the level of a free application installed on a mobile device. EFC-02 is intended for control within a local area network. Remote access is only possible for users who have a fixed external IP address and make appropriate redirections on the router.
